SITE PREPARATION REQUIREMENTS The Model 204 Weight Indicator is a precision weight indicating instrument. As with any precision instrument, it requires an acceptable environment to operate at its peak performance and reliability. This section is provided to assist you in obtaining such an environment. Environmental The Model 204 Weight Indicator meets or exceeds all certification requirements within a temperature range of 14 to 104 °F (-10 to +40 °C).
INSTALLATION Unpacking Carefully remove indicator from shipping carton and inspect it for any damage that may have taken place during shipment. Keep carton and packing material for return shipment if it should become necessary. The purchaser is responsible for filing all claims for any damages or loss incurred during transit. Should your indicator come already installed on a scale, the following installation information does not apply to you.
INSTALLATION, CONT. Serial I/O Load Cell Ground Lug Thumb Screw 12 VDC Battery Door Figure No. 2 Batteries The 204 indicator can use 6 "C" size Alkaline, Ni-Cad or NiMH batteries (not included). You must first obtain and install batteries in the 204 before operations can begin. The batteries are contained in a battery holder inside the indicator. Access is via a removable panel on the back of the indicator.
INSTALLATION, CONT. Battery Installation/Replacement To install or remove the batteries, the following steps should be followed: 1. Make sure the AC power adapter is unplugged. 2. Remove the indicator from the mounting bracket and turn the indicator over so that the display is facing away from you. 3. Locate the rectangular panel on the back of indicator and remove the thumb screw. 4. Remove the panel (lift straight up and slide it out) exposing the battery holder. 5.
INSTALLATION, CONT. Battery Status If batteries are used, the indicator will show the battery status on power up. The display will show battry then change to ð YY ð, where YY indicates the remaining battery voltage expressed as a percentage (%) of the total battery voltage. Battery Charging To recharge the Ni-Cad or NiMH batteries, the AC power adapter must be connected to an AC power outlet and plugged into the indicator. It will take approximately 15 hours to fully recharge the batteries in the scale.
INSTALLATION, CONT. Main PCB and Jumpers Figure No. 5 J1 and J2 - Sense Jumpers If sense leads are NOT used, you must install plug-in jumpers at J1 and J2 (adjacent to the P1 connector). These jumpers attach the sense leads to the excitation leads. If sense leads ARE used, these plug-in jumpers should be positioned on one plug-in pin only or removed and stored for later use. Refer to Figure No. 5 for the location of the jumpers.
SERIAL DATA FORMATS Weight-On-Demand If the Printer Continuous output was not selected, COnt=0 (0=NO) during setup and calibration of the indicator, and the 204 is connected to a computer, it will transmit a single set of weight data each time the computer sends an ENQ (hex 05) or a SMA weight request (W). This is known as Weight-On-Demand. Examples and explanation of the data format transmitted are shown below.
KEYPAD FUNCTIONS Figure No. 7 The membrane keypad is not to be operated with pointed objects (pencils, pens, fingernails, etc). Damage to keypad resulting from this practice is NOT covered under warranty. ON / OFF (I / O) KEY With the indicator off, pressing this key will apply power to the 204 and turn on the display. If the indicator is already on, pressing this key will remove power from the indicator.
KEYPAD FUNCTIONS, CONT. UNITS / S (UP ARROW) KEY This key is used to change the weighing units to the alternate units of measurement if selected during setup of the indicator (WEIGHTING UNITS = 3 or 4). For example, with pounds displayed (lb annunciator turned on) pressing this key will change the weighting units to kilograms (kg annunciator will turn on). NOTE! This feature must be enabled during setup and calibration for this key to be operational.
ANNUNCIATORS, CONT. lb The lb annunciator is located on the right of the weight display and is turned on to show that the displayed weight units is pounds. kg The kg annunciator is located on the right of the weight display and is used to indicate that the displayed units of weight measurement is kilograms. oz The oz annunciator is located on the right of the weight display and is turned on to show that the displayed weight units is ounces.
SETUP AND CALIBRATION Your 204 indicator has been thoroughly tested and calibrated before being shipped to you. If you receive the indicator with a scale, calibration is not necessary. If the indicator is being connected to a scale for the first time or recalibration is necessary for other reasons, proceed as indicated. Calibration of the 204 indicator is accomplished entirely by the keypad. To enter the setup and calibration mode: 1.
SETUP AND CALIBRATION, CONT. Decimal Point Location With the display showing dPP= press the ASTERISK key to show the current setting. Press the UNITS key until the number corresponding to the desired decimal point position is displayed. Press the PRINT key to store this setting and proceed to the next step. 0 = XXXXX 1 = XXXX.X 2 = XXX.XX 3 =X X.XXX Scale Capacity With the display showing CAP= press the ASTERISK key to show the current setting.
SETUP AND CALIBRATION, CONT. USA (Domestic or International) The display will next indicate USA=. This is the prompt to select whether the 204 is used in the USA (domestic) or outside the US (international). Press the ASTERISK key to show current setting, then press the UNITS key to select 1 (1=YES, Domestic) or 0 (0=NO, International). USA = 1 (Domestic) No Zero Limit Tare Resolution = 1d (1 division) USA = 0 (International) +/- 2% Zero Limit Tare Resolution = .
SETUP AND CALIBRATION, CONT. Hold Key Enable The display will next indicate HLd= which is the prompt for the selection to enable or disable the Hold (ASTERISK) key. This mode of operation will lock the 204 display and is used only in noncommercial applications. Press the ASTERISK key to show the current setting, then press the UNITS key to select 1 (1=YES, enable) or 0 (0=NO, disable). Press the PRINT key to save the setting. NOTE! This feature must be set to 0 (0=NO) for “Legal for Trade” applications.
SETUP AND CALIBRATION, CONT. Sleep Mode The display will now show SLP=. The Sleep Mode feature also conserves battery power when the indicator remains unused for a selected period of time. With the feature enabled, the load cell excitation will be reduced and the display will show SLEEP. The Sleep feature requires that the indicator remain at the center of zero to activate, unlike the Automatic Shutoff feature which only requires no motion.
SETUP REVIEW The 204 allows several operational parameters to be reviewed and changed as necessary without having to enter the setup and calibration mode. The parameters in the setup review will be processed in the following sequence: NiCAd= Disable battery charging (use Alkaline batteries), Enable battery charging (use Ni-Cad or NiMH) or Enable battery charging and Force charging of discharged Ni-Cad or NiMH batteries.
CALIBRATION SEAL INSTALLATION If your Model 204 Weight Indicator is used in a commercial application it must be tested and sealed by your local weights and measurement official. The 204 is designed to accept a lead and wire security seal to prevent unauthorized access to the calibration adjustments. Refer to the Figure No. 9 for details on the installation of the seal. Right End Cap Left End Cap (Indicator as viewed from rear) Figure No. 9 CARE AND CLEANING 1.
ERROR AND STATUS DISPLAYS The 204 is equipped with a diagnostic software program that tests various portions of the indicator's circuitry and verifies proper operation. Should a problem be detected, an error or status message will be displayed alerting the operator to that condition.
