GENERAL DESCRIPTION The Hanna PCA 310, PCA 320 and PCA 330 series of chlorine, pH, ORP and temperature analyzers are microprocessor controlled, process analyzers which continuously monitor a sample stream for chlorine content, pH, ORP and temperature values. The PCA 310-330 monitor the free chlorine or total chlorine in the 0 to 5 mg/L range depending on the factory settings and used reagents. In the DPD Colorimetric method, N, N-Diethyl-p-phenylenediamine indicator and a buffer are mixed with the sample.
13 standards. Molded fiberglass polyester has outstanding chemical and temperature resistance. The case provides wall mounting capability and door gasket assures a watertight and dust-tight seal. The electrical and hydraulic connections are made through the side of the enclosure. The front cover is secured with two lockable latches. Four chlorine level setpoints can be adjusted by the operator: a proportional dosing setpoint, two alarm setpoints and a minimum level for dosing.
The analyzer can store up to 3500 readings (at least 7 days at 3 minutes sampling interval), that are available for consulting or downloading. The PCA 310-330 analyzers can be monitored or controlled through RS485 or GSM network connection. Errors, alarms and warnings are sent through SMS (using GSM module HI 504900). The analyzer state can be interrogated by a simple call using GSM phone.

OPERATING DESCRIPTION CHLORINE MEASUREMENT Referring to the drawing on page 10 and the Fluidic Diagram on page 17, the Sample Line is connected to the instrument at the Sample Port (#17); an internal Regulator (#15) reduces the inlet pressure from a maximum of 4 bar (57.2 psi) down to 1 bar (14.3 psi); from the Regulator a nylon tube is connected to the input of the Electrovalve (#21). The output of the valve goes to the Drain Port (#11) and then to the Measuring Cell (#7).
METHOD OF ANALYSIS TO DRAIN Free available chlorine oxidizes the DPD indicator reagent at a pH SAMPLE OUTLET between 5.5 and 6.0 to form a magenta-colored compound. The intensity of the resulting color is proportional to the concentration SAMPLE INLET of chlorine in the sample. The purREAGENT BOTTLES pose of the buffer solution is to maintain the proper pH. To measure total residual chlorine (free available chlorine plus combined chlorine) the PCA adds potassium iodide.
INITIAL PREPARATION AND INSTALLATION INSTALLATION PERSONNEL Installation of the PCA 310-330 Chlorine, pH, ORP and temperature analyzers should be undertaken by persons with technical knowledge of the dangers associated with chemical exposure and electrical shock. Hanna Instruments assumes that persons performing the installation tasks are aware of the appropriate safety procedures. CAUTION:Review the Material Safety Data Sheets (MSDS) before handling the supplied chemical reagents.
A 1/2 BSP sample input fitting allows direct connection to the optional input filter. Sample line pressure should be between 0.07 and 4 bar (1 and 57.2 psi) with an ideal pressure of 0.7 bar (10 psi). It is recommended to assure that the water inlet come at 1 m above the instrument sample input pitting. For maintenance issues is also recommended to install valves on both sampling pipes. WATER OUTLET WATER INLET ORP probe MIN.
Return Line Installation The return hose fitting is a 12 mm (1/2”) hose barb on the bottom of the regulator output port and should always be connected even when pressure is below 1 bar. INSTALLING THE INPUT FILTER In order to ensure maximum accuracy of measurements, it is recommended to have always clear sample, with suspended particles smaller than 0.5 μm. This can be achieved by installing two filters before the sample input.
the protective cap from electrodes and electrodes connectors. HI 1005 Screw the pH probe (HI 1005) in the lower position and the ORP probe HI 2008 (HI 2008) in the higher position and assure that no leakage occurs. Only after the probe is in final position connect the probe to the dedicated connector. Lock the connector with the built in nut. Warning:: Never connect or disconnect the probes when the analyzer is powered on. INSTALLING THE PUMP TUBES Locate the analyzer reagent tubes in the accessory kit.
Note: them. Place the indicator bottle (HI 70450 for free chlorine and HI 70460 for total chlorine) on the right and the buffer bottle (HI 70451 for free chlorine and HI 70461 for total chlorine) on the left. Add the content of 5 HI70452 sachets, DPD Compound, to the Indicator Solution prior to installing it. Connect the longer tube ends on the left side of the pump to the reagent bottle cap insert fitting.
3) Open front panel. 4) Remove the cover screws (Allen head). 5) Do not remove peristaltic pump or motor. 6) Unplug all alarms and recorder jacks. Feed the power cord through the watertight grommet and tighten the grommet nut. See the picture below for proper wire connections.
Alarm Relay Note: A system alarm feature provides relay activation ALARM to signal that the measuring value exceed the alarm setpoints. The alarm relay is closed (Common connect to Normal Close) if the value is lower than alarm low setpoint or higher than C NO NC alarm high setpoint. The ALARM LED blinks when alarm is active. The Alarm relay is power-fail safe and is closed when the analyzer is not powered.
I Acid/alkali Dosing Relay Acid/alk dosing relay is activated (Common connected DOSING to Normal Open) depending on the setpoint and pH selected delta. If the analyzer is set to dose acid, the relay is active when the pH value is over the setpoint. If alkaline is dosed, the relay is activated when the C NO pH value is under the setpoint. The DOSING ACID/ALK. LED is turned on when the dosing relay is closed. Note: The acid/alk dosing is stopped when system error related to pH occurs.
STARTUP To power up the analyzer open the electronic box door and turn on the main switch. When the analyzer is powered up, the display backlight is turned on and the initialization take place. In this phase, the integrity of the stored data is checked and the information regarding the language is loaded. The display will show HANNA INSTRUMENTS, the name of the instrument and the software version.
USER INTERFACE PANELS ORGANIZATION ORP panels Temp. panels pH panels Cl panels The PCA 310 – 330 analyzers provide a friendly interface that display all important parameters of the analyzer. The appearance of the display could be selected by the user. The panels are organized UP/DOWN in circular loops.
One row with messages is also displayed. When the display 08:10 show one of this pan6.29 pH Error els, pressing “CFM”, < Low ORP > will enter in the panMin:4.18 Max:7.00 els related to the parameter displayed in the left side. Example: When pH is displayed on the left side and the chlorine, ORP and temperature on the right side, pressing “CFM” will go in one of the pH measure panels. MEASURE PANELS For each parameter, several measure panels are available.
The display go in large digits panel if no key 16:49 is pressed for about 4 minutes. If key is mg/L pressed, the display returns in the panel where it was before. Pressing “ESC” when in one of those panels will return in main panels mode. MESSAGES When warnings, alarms or errors appears, the message line is displayed. The meanings of each message is explained in chapter ERRORS, ALARMS AND WARNINGS. If many messages are present, the “<“and “>” signs are displayed on the left and/or the right side.
If correct password is entered and confirmed, the analyzer will go in menu mode. If wrong password is entered, the analyzer displays “Password incorrect. Settings are not allowed!”, and the user could only view the analyzer parameters. NAVIGATING THROUGH MENU The menu is organized as a list of options. Each line of this list: - could contain a General Menu sub-menu; Chlorine Menu - could display an pH Menu analyzer parameter or ORP Menu - could start a funcTemperature Menu tion.
For list type parameter In this case the cursor will blink and first letter alternates with a black square. To modify the value press “UP” or “DOWN” arrow key until the correct value appears. Setpoint :2.50 mg/L Delta :0.1 mg/L Low Point:0.02 mg/L Low Point:Inactive Press “CFM” to save the value or press “ESC” to end the editing without saving the value. For single numeric values In this case the cursor will blink by alternating the first digit and a black square.
Note: Pressing “RIGHT” or “LEFT” arrow keys, another parameter can be set. Pressing “ESC” key will return to menu. If the edited value is outside the allowed range, a warning panel appears when “CFM” is pressed. This panel contains the parameter limits. Pressing again “CFM” or “ESC” will return to the edit mode. PROGRAMMING THE ANALYZER To set the parameters press “MENU” while in the measure mode. The main Menu is displayed.
GENERAL SETTINGS The analyzer settings, common for all measurements, are grouped in “General Menu”. CHANGING THE PASSWORD System Log Analog Output SMS Settings Serial & GSM Comm. Time and Date System Functions Language Change The password is a numeric value with 4 digits. To change the password, enter in “General Menu” - “System Functions” and edit the “Change Pass” line. Press “CFM” to save. After new value is confirmed, the displayed password is set to 0000 for protection against unauthorized reading.
WORKING MODE Three working modes could be selected for the analyzer. The selection is available in “General Menu” “System Functions” “Manual Commands” - “Work Mode”. The work mode could be set as AUTOMATIC, STANDBY or MANUAL. Work Mode:AUTOMATIC Read On Demand Alarm Relay :ON Dose Cl Rel :ON Dose pH Rel :ON Sys.Err. Rel:OFF Stirrer :OFF Valve :OFF Cell Led :OFF Reagent Pump:OFF AUTOMATIC MODE In this mode the analyzer performs the measurements continuously accordingly with the settings.
Note: READ ON DEMAND When this function is selected, (“General Menu” - “System Functions” - “Manual commands” - “Read On Demand”) a new chlorine measuring cycle is immediately started. This command is useful when calibrate or whenever an immediate result is needed. The read on demand function is active only when the analyzer is in automatic mode. DIRECT READ For rapid diagnostics of the measuring cell, the converter readings for dark (cell LED off) and blank (cell LED on) could be consulted.
CHLORINE SETTINGS The settings related to chlorine measurement are grouped in “Chlorine Menu”. The following options are available: REAGENT CHANGING One set of reagents is enough for at least 16000 samples. The remaining doses of reagent are displayed on one chlorine measuring panel. When the reagent is changed, several actions must be performed: Prepare the reagent and install the new bottles as described in initial preparation and installation chapter.
MEASURE SETTINGS Select “Chlorine Menu” - “Measure Settings” and set the “Period” between 3 and 90 minutes. Period (sampling rate) is the elapsed time between two consecutive chlorine measurements. The sampling rate is also important when the analyzer is used for chlorine dosing. For larger pools, the period must be longer, and for smaller pools, the period must be shorter. The sampling rate can be quickly consulted on one chlorine measuring panel.
delta The output will be proportional with chlorine if the read value is between those limits. Example: if the 0.0 to 20.0 mA recorder output has been selected, the operator can select 0.0 mA to correspond to a concentration of 3.00 mg/L (Min. Rec. setting) and 20.0 mA to correspond to a concentration of 4.50 mg/L (Max. Rec. setting). The full scale span of the recorder would then be 1.5 mg/L, yielding a magnified view of the 3.00 to 4.50 mg/L concentration range on the recorder.
To modify the Delta, edit the “Delta” line. The available values are 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.5, 2, 3, 4, 5. Note: The speed of the analyzer could be modified by changing the sampling rate. A new decision regarding the chlorine regulator is taken only after a new measurement. The Setpoint and Delta could be quickly consulted on one chlorine measuring panel.
Note: The alarms could be separately activated or inactivated. To modify the alarms status, enter the “Chlorine Menu” - “Alarms Chlorine” menu and edit “Alarm Hi” or “Alarm Lo” status. When the status is set to “Inactive”, the alarm is ignored. The Alarm high must be greater than Alarm low value. The analyzer display a warning if the settings are incorrect. The Alarm high setpoint and Alarm low setpoint could be quickly consulted on one chlorine measuring panel. When an alarm is disabled, the —.
Note: • With a calibrated meter take a measure of the sample. This is the calibration value. • Wait for the PCA to display the new reading. • Go in “Chlorine menu” - “Cal. Measuring Cell” and edit “Cal. Value” field. • Enter the calibration value and save with “CFM”. • The calibration coefficient and the calibration date will be updated. • Press repeatedly “ESC” to exit from menu mode. The displayed chlorine concentration will be equal with the calibration value.
ANALOG OUTPUT The type of analog output could be set as described in “Analog output” chapter. The analog output span for pH could be set in “pH Menu” - “Analog Output pH”. “Min. Rec” will set the recorder low limit and “Max. Rec” will set the recorder high limit. The Max. Rec. value must be greater than Min. Rec. value. The output will be proportional with pH value if the read value is between those limits. The analog output limits could be quickly consulted in one of the pH measuring panel.
Note: Note: Note: The analog output will have the value: analog output [mA] = 4 + 16 * dosing time/Period [mA] If the measured pH is lower (or higher for acid dosing) than setpoint minus (plus) delta, the dosing will be continuous until the pH period elapsed. To modify the dosing setpoint, enter the “pH Menu” - “Dosing Control pH” edit the “Setpoint” line. The value must be between 2.00 and 12.00 pH. To modify the Delta, edit the “Delta” line. The available values are 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.
To modify this protection, edit “pH Menu” - “Dosing control pH” - “Max. ON” value. The allowed range is between 30 and 720 minutes. ALARMS Note: Two alarm setpoints are available for pH: Alarm high and Alarm low. The ALARM LED and relay are activated when the pH value is higher than Alarm high or lower than Alarm low. To modify the alarms setpoints, enter the “Alarms pH” menu and edit “Alarm Hi” value or “Alarm Lo” value. The alarms can be separately activated or inactivated.
For accurate calibration use two different beakers for each buffer solution, the first one for rinsing the probe and the second one for calibration. By doing this, contamination between buffers is minimized. Unscrew the probe from its position. Take care to stop the sample flow before removing the probe. If necessary, disconnect the probe from analyzer to prevent the damage of the probe cable. ONE POINT CALIBRATION Immerse the pH probe into the buffer solution Probe (e.g. pH 7.
• The analyzer prompts for the second buffer selection, and displays the message “Select buffer pH... or press SET for one point cal.”. Pressing “SET” key will end the one point calibration procedure. TWO-POINTS CALIBRATION • To perform a two-points pH calibration follow the steps described at one-point calibration until the analyzer displays the message: “Select buffer pH... or press SET for one point cal.”. • Immerse the pH electrode into the second buffer solution (e.g. pH 4.
Note: • Wait for readings to stabilize. • Enter in “pH Menu”- “Cal. pH Probe” - “Process pH Cal.” and enter in the Cal. Value:06.84 pH “Cal. Value” field the reading from the reference pH meter. • Press “CFM” key when the analyzer prompt for “Overwrite pH cal. ?”. •The analyzer checks for readings stability (see One-point calibration) and when the value is stable the message “Stable... press CFM” is displayed. • Pressing “CFM” key will complete the process pH calibration.
TEMPERATURE SETTINGS (PCA 320, PCA 330) Settings related to temperature measurement are grouped in “Temperature Menu”. The following options are available: UNITS Note: The analyzer could display the Temperature using Celsius or Fahrenheit temperature units. To select the temperature units, edit the “Temperature Menu” “Units” line. Select Celsius or Fahrenheit and confirm. The temperature values sent via SMS are always the Celsius values.
“Min. Rec” will set the recorder lower limit and “Max. Rec” will set the recorder higher limit. The Max. Rec. value must be greater than Min. Rec. value. The output will be proportional with temperature value if the read value is between those limits. The analog output limits could be quickly consulted in one of the Temperature measuring panel. ALARMS Note: Two alarm setpoints are available for temperature: Alarm high and Alarm low.
ORP SETTINGS (PCA 330) Settings related to ORP measurement are grouped in “ORP Menu”. The following options are available: Alarms ORP Analog Output ORP Measure Info MEASURE INFO The analyzer calculates the maximum and minimum ORP value since the first measurement. The maximum and minimum can be quickly consulted on one ORP measuring panel. For more detailed information select “ORP Menu” - “Measure Info” The “Max. Value” and “Min.
ALARMS Note: Two alarm setpoints are available for ORP: Alarm high and Alarm low. The ALARM LED and relay are activated when the ORP value is higher than Alarm high or lower than Alarm low. To modify the alarms setpoints, enter the “ORP Menu”-“Alarms ORP” menu and edit Alarm Hi value or Alarm Lo value. The alarms could be separately activated or inactivated. To modify the alarms status, enter “ORP Menu” - “Alarms ORP” menu and edit “Alarm Hi” status or “Alarm Lo” status.
ANALOG OUTPUTS The PCA 310-330 analyzers has two current analog outputs. Each one can be configured as 0-20 mA, 4-20 mA or dosing type. Also they can be assigned to one of the measurement parameters: Cl, pH, Orp, Temp. SELECT THE ANALOG OUTPUT TYPE To select the analog output type enter in “General Menu” “Analog Output1” or “Analog Output2”. The analog output Out Param.:Chlorine could be assigned Type :Dosing to one of the four Cal.Analog Out Max. measured parameters. Cal.Analog Out Min.
CALIBRATE THE ANALOG OUTPUTS Note: The analog output is factory calibrated. Recalibration is not needed when the output type is changed. If, for any reason, a new calibration has to be performed, each output type could be easily calibrated. To calibrate the current type analog outputs, follow the steps: • Connect an ammeter to the pin 1 and 2 / pin 3 and 2 of the output connector. • Enter in menu mode and select “General Menu” - “Analog Output” sub-menu.
OUTPUT MIDDLE RANGE To easily adjust a recorder offset, the analog output could be set to middle range. In this case the output is set to 12 mA or 10 mA for 4-20 mA or 0-20 mA output. To activate this option select “General Menu” - “Analog Output1” or “Analog Output2” - “Output Middle Range” function and press “CFM” key. The analyzer will display “Recorder output is set to middle value”. Press “ESC” to exit from this function.
SYSTEM LOG The PCA 310-330 analyzers have a permanent logging function. Up to 3500 records could be stored. At a sampling interval of 3 minutes the log covers more than 7 days. If the logging memory is full, the oldest record is lost when a new record is stored. The record contains the date and time, the chlorine, pH, ORP and temperature value and the status of errors and alarms. SET LOG The data are stored after the chlorine measuring cycle is completed.
When the searching is in work, the message “Searching Records” is displayed. The search result could be: • “No records found” meaning that no records were found with specified criteria. • “No records stored” meaning that there is no record in log. • Display the log. The records will have the following structure: 1 2 3 14:38 14:33 14:27 14:22 1.00 1.05 1.20 1.17 5.86 5.63 A 4.99 E 5.
6 – The Temperature value and units (°C or °F) 7 – The Errors and Alarms If many errors or alarms are present, the “<” and “>” signs are displayed on the left or right side of the display. Selecting another message could be done by pressing “LEFT” or “RIGHT” arrow keys. Pressing three time “ESC” will return in the main menu. SERIAL COMMUNICATION I The PCA 310-330 have one RS485 serial communication port. The serial communication is galvanically isolated from other analyzer parts.
GSM GSM MODE If the “Type” is set to GSM, the analyzer will work with HI 504900 GSM module. This connection enables the analyzer to send SMSs to one (or two) cellular phone(s) and through this feature the device can be monitored. Moreover if an error occurs on the PCA 3x0, a SMS is sent to the cellular phone(s) signaling immediately the user about the problem. When the SMS feature is active, three type of SMS messages are sent to the selected cellular phone(s).
One or two phone numbers associated with the service - to which the messages will be sent – must be set. The number has to be entered in the fields named “No1” and “No2”. The space reserved for a phone number is 15 digits. The phone numbers have to be inserted using the international format excluding the starting + character and without any space inside the number. Example: if the cellular number is +39123456789 (+39 is the country code), the number to be stored in the PCA 310-330 is 39123456789.
If a wrong PIN was entered three times, the user has to extract the SIM card and manually enter the PUK number using his own cellular phone to unlock the SIM card. Note: There is no need to modify the default baud rate (1200) of the serial link when enable the GSM feature. It will be switched to 9600 automatically. SETTING SMS FEATURE In order to avoid the frequent sending of the SMSs or rapid consuming of the GSM credit when one measuring channel not work correctly, the SMS sending could be customized.
The phone call advises the user that something happened on the PCA analyzer and SMS is going to be received. Is not necessary to answer the phone call and it is suggested to close it without any answer. A confirmation of the alarm message reception is waited by the analyzer. The confirmation can be done by simply calling the PCA analyzer phone number (number of the GSM module).
Note: If the analyzer is waiting for confirmation after sending an alarm SMS, the received SMS will be just stored on the SIM until the confirmation is coming or all the repeated alarm SMSs are sent. The info SMS will always contain the Chlorine, pH, ORP and Temperature readings and the Settings and Errors if enabled. Also, the remaining SMSs number will be added if “Chk. Charge” is active. Example of info SMS: “Temp Err;L Ph;H Temp; READINGS: ReagRem=8413;Cl=2.05; pH=7.02;Orp=700;Temp=25.
Note: Note: This particular situation is managed as an error occurrence and a confirmation of the SMS reception is waited. After that, a “GSM no credit” warning appears on the display signaling that no other SMS can be sent. In this case the user is supposed to extract the SIM card from the cellular module as soon as possible and check the remaining credit (using its own cellular phone and calling the network operator).
MODEM CONNECTION Note: 64 Modem connection can be established between PCA 310-330 and a remote computer. The connection allows the user to interrogate the analyzer, from remote position, about its status and measurements and to change analyzer parameters. Also the log could be downloaded through remote connection. A SIM card able to receive data calls must be used in HI 504900 GSM module.
MAINTENANCE The PCA 310, PCA 320 and PCA 330 analyzers incorporate several technologies to minimize the maintenance. Also, if the GSM module is connected, the warnings, alarms and errors are sent to the operator, making the maintenance even simpler. The analyzer status could be sent via SMS messages after a call from operator. Calibration of the chlorine measuring circuits is not normally required. The DPD technique for measuring chlorine concentration is well established and consistent.
ELECTRODE CONDITIONING AND MAINTENANCE Preparation Remove the probe protective cap. DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal with probes and they will disappear when rinsed with water. During transport tiny bubbles of air may have formed inside the glass bulb. The probe cannot function properly under these conditions. These bubbles can be removed by “shaking down” the probe as you would do with a glass thermometer.
Cleaning procedure General Soak in Hanna HI 7061 General Cleaning Solution for approximately ½ hour. Removal of films, dirt or deposits on the membrane/junction: Protein Soak in Hanna HI 7073 Protein Cleaning Solution for 15 minutes. Inorganic Soak in Hanna HI 7074 Inorganic Cleaning Solution for 15 minutes. Oil/grease Rinse with Hanna HI 7077 Oil and Fat Cleaning Solution.
CHANGING PERISTALTIC PUMP TUBING It is recommended that the peristaltic pump tubes be changed on a regular basis depending on sampling period and operating time. For a 5 minutes sample interval and continuous operation, changing of the tubes every month is recommended. For best results however, change the tubings every time the reagents are replaced. Note: Rubber gloves and eye protection must be worn while handling reagent tubing to prevent contact with reagent chemicals.
TUBING REPLACEMENT The remaining tubing in the analyzers should be replaced every two months. HI 70479 HI 70474 or HI 70475 HI 70473 When installing new tubing it is helpful to dip them in hot water before making the connections. It is also recommended that one tube at a time is removed and replaced. Note: DPD reagent tubing may darken before the scheduled replacement time, but this will not affect the instruments performance.
Allow sulfuric acid to stand in the measuring cell for 15 minutes to dissolve any foreign materials adhering to the cell walls. Wipe the cell interior with a cotton-tipped swab. After wiping, open the drain port to empty the measuring cell from the cleaning solution. CHANGING MEASURMENT CELL Note: 70 To change the measuring cell (#7 page 10) with a new one (HI 70487) in the PCA310 - 330 analyzers, follow the steps: • Stop the analyser by turning off the main switch.
ERRORS, ALARMS AND WARNINGS The possible error, alarm and warning messages are described below with a short suggestion about the needed action to remove the error. The pH and temperature related messages are present only on PCA 320 and PCA 330 and the ORP related messages are present only on PCA 330. The warning messages appears on LCD and some of them on SMS. The measuring is not stopped on warnings.
The chlorine value not increase at least with 0.05 ppm even if the chlorine dosing pump is running full time for “Max On time”. In this particular case, the error is cleared only when the controller is restarted. This could be caused by absence of the chlorination agent, the malfunction of the dosing pump or malfunction of the detector. Check the presence of the magnet barr, check the reagent level, check the reagent pump tubes, clean cell, observe if the sample flow in the cell, edit the “Low Point”.
H ORP “High ORP” on LCD and “H ORP” on SMS High ORP The ORP is over the Alarm High setpoint. Change the setpoint, verify the ORP probe. “Low ORP” on LCD and “LL ORP ORP” on SMS Low ORP The ORP is under the Alarm Low setpoint. Change the setpoint, verify the ORP probe. “High emperature” on LCD and “H emp” on SMS High TTemperature emperature H TTemp emp The Temperature is over the Alarm High setpoint. Change the setpoint, verify the pH probe.
Recharge the SIM card and change the expiration date or set the “Chk. Charge” Inactive. “GSM GSM No Credit”: Credit appears on LCD The number of remaining SMS is 0.
