Pub.# OM17-MSP-pH Procedure #1: Checking power inside External Controller The Veris pH module requires a minimum of 12 volts at all times. 12 volts at the battery terminals is NOT sufficient power for the system to function, due to the significant current draw when the pumps and solenoids are engaged. Reduced voltage can be caused by corroded or dirty terminals, and an inadequately charged battery or failure in the charging system.
Pub.# OM17-MSP-pH POWER (12V) FUSE 2 (10A) and its LED 12V C 5V FUSE 1 (500 mA) and its LED Figure 1.2 External Controller circuit board (metal cover removed) 2. Turn off power to External Controller, remove clear lid and remove and replace any fuse that has failed. 3. Check voltage with a digital voltmeter at power supply connection All functions must be engaged during this test.
Pub.# OM17-MSP-pH If voltage at power connector drops below 12 volts during this test: a) clean battery terminals b) check disconnect contacts c) hook power leads directly to battery—not through tractor power port d) charge battery 4. Check voltage at power cable (Figure 4). If 12V at cable but not on circuit board—call Veris Service Dept. Figure 1.
Pub.# OM17-MSP-pH Procedure #2: Trouble-shooting Sampler Cylinder Hydraulics The Veris pH module uses electro-hydraulics to perform the cycling functions. If the sampling shoe hydraulic cylinder is not functioning properly, the cause of the problem must be traced to either the electronic or the hydraulic side. This Procedure will guide you through the steps necessary to identify the problem when the sampler cylinder in manual mode is not moving or only moves in one direction.
Pub.# OM17-MSP-pH SOLENOID LED’s UP 12V C 5V DOWN Figure 2.2 External Controller circuit board (metal cover removed) 3. Test voltage coming out of External Controller to solenoids. Disconnect the weather-pack connectors in line from Controller to the solenoids. Using a digital voltmeter set to read voltage, insert leads into connector coming from Controller. Activate manual raise-lower switch and read voltage. (Figure 4) Voltage should be 12 volts. Figure 2.
Pub.# OM17-MSP-pH 4. Test continuity of coil. With voltmeter set to ohms (resistance), insert both leads into the weatherpack connector leading to each solenoid. Start at the jumper wire (at first connection from external controller) and move to connector at solenoid. This tests the continuity of the signal through the coil. You should have continuity if the coil is working. Test both solenoids. Figure 2.4 Testing continuity of solenoid coil (at weather-pack connector on jumper-wire) 5.
Pub.# OM17-MSP-pH Procedure #3: Trouble-shooting Communication Problem between Instrument and External Controller Communication between the Veris Instrument and the External Controller is required for the system to initialize (sampler cylinder moves to neutral), and function. A communication failure between these components may be expressed as INIT ERR (initialization error) or COMM ERR (communication error). Follow flow chart below to address problems in their logical sequence. Figure 3.
Pub.# OM17-MSP-pH Figure 3.2 Inspecting pins on communication cable 2. Testing continuity on communication cable. a) Unplug the communication cable from the DataLogger or PC. b) Bring both ends of the communication cable close enough together to reach with a voltmeter. c) Set your voltmeter to resistance (or continuity). Check continuity between the following pins: (Figure 3.
Pub.# OM17-MSP-pH 3. Testing continuity from the circuit board through the communication cable a) Remove the steel cover and unscrew the plastic lid from the external Controller. b) Look for the brown Molex 3-pin connector circled in Figure 4. The color sequence (left->right) should be white-green-black. CAREFULLY wiggle each wire to check for a loose connection. c) Check continuity between the following pins: Figure 3.
Pub.# OM17-MSP-pH 4. Testing that the external controller is receiving/acknowledging the command sent to it by the DataLogger or PC. a) Turn on the external pH Controller. b) Open up a HyperTerminal session on a PC: Click Start►Programs►Accessories►Communications►HyperTerminal. A new session of Hyper Terminal should open. In the box labeled “Connect using___” you will need to select the Com port you will be using. (on Windows 2000 and older: Under the Call menu, click Disconnect.
Pub.# OM17-MSP-pH 5. Testing that the instrument is sending the proper command to the external controller. a) Connect the DataLogger or PC to the PC using a serial cable (you will need a null modem and may need a gender changer). Turn on the DataLogger or PC and enter data acquisition. The data in Hyper Terminal should look like this $U♥♦Ç$U♥♦Ç The important letter above is the ‘U’, but the data coming up should match this character-for-character. The ‘U’ is the letter the pH Controller is looking for.
Pub.# OM17-MSP-pH Procedure #4: Trouble-shooting Prox Sensor The prox sensor, located on the left of the sampler shoe parallel linkage arm, is critical to the machine’s function. It informs the external controller of the sampler’s position, which allows the controller to move the sampler to the next position in the sampling/measuring sequence. If the prox sensor is not functioning properly, the entire operation will be affected. The problem may be with the Prox sensor itself or with its adjustment.
Pub.# OM17-MSP-pH 2. Adjust prox sensor gap if needed. Adjust sensor to 1/4”- 3/8” (6-9 mm) gap (Figure 2). Cycle unit manually to insure that this gap is maintained throughout cycling range. 1/4 to 3/8” gap (6-9 mm) Figure4.3 Prox sensor gap 3. Adjust prox sensor height if needed. Loosen bolt holding prox sensor arm and rotate to change height of prox sensor (Figure 3). Adjust prox sensor height with sampler shoe completely raised.
Pub.# OM17-MSP-pH 4. Check voltage to prox sensor if needed. Disconnect sure-seal connector from external controller to prox sensor. Check for 12V voltage on socket #1 and pin #3 from external controller, with power to external controller turned on (Figure 4). Do not short across voltmeter leads. Figure 4.
Pub.# OM17-MSP-pH Procedure #5: Diagnosing GPS-related problems If you do not see a GPS, DGPS, or RTK in the upper left-hand corner of the EC Surveyor screen, you do not have GPS coming in, and no data will be sent out the serial port for logging. Figure 5.1 Insure your GPS receiver is powered and outputting NMEA strings GGA, and either VTG or RMC at a 1hz rate; 4800 baud, 8 data bits, no parity, 1 stop bit.
Pub.# OM17-MSP-pH If it becomes necessary to send GPS data into your PC, you will use a program called HyperTerminal. This program is in all Windows software. It is designed to record serial data streaming into a serial or USB port on the computer. The purpose of this is two-fold: 1) it verifies whether your GPS and cables are delivering the proper messages, and 2) it give Veris Technologies support personnel a GPS data file to test. Here’s how to use HyperTerminal 1.
Pub.# OM17-MSP-pH 5. The program will then ask you for a phone number. Instead of entering a phone number, specify the proper serial port number. For example, if Com 1 of the laptop is being used, specify “Direct to Com 1” under “connect using:” at the bottom of the entry area. Figure 5.5 6. HyperTerminal will then display a configuration menu where you can specify 4800 bits per second, 8 data bits, no parity, 1 stop bit and no flow control. Figure 5.
Pub.# OM17-MSP-pH 7. At this point, upon clicking ok, legible strings of GPS data should begin appearing on the laptop screen. Here’s an example of a typical set of strings: $GPGGA,191528.00,3851.0333,N,09737.2342,W,2,08,1.3,372.7,M,27.3,M,10.0,0100*69 $GPRMC,191528.00,A,3851.0333,N,09737.2342,W,0.1,0.0,090998,6.3,E*48 8.
