Wireless System Diagnostics
Possible Solutions:
- Check for proper wiring and connections from the output modules to the controller.
- Check to see if the controller’s software is configured properly.
- Check for proper power to the receiver, repeater (if used) and output modules.
- Retrain the Analog Output Module.
- Check that the associated transmitter is transmitting (the LED will flash about once
every 10 seconds when it transmits). If not, replace the batteries. Check that the
associated receiver is receiving the tranmissions (its LED will blink right after the
transmitter LED if it receives that transmission.) If it is not receiving the transmissions,
move it closer to the transmitter or reposition the antenna for maximum reception.
Note:
The receiver will receive transmissions from all transmitters that are within
range, not just the one you are testing.
- Retrain the Analog Output Module.
- Check for proper wiring and connections from the output modules to the controller.
- Check to see if the controller’s software is configured properly.
- Check to see if the correct output module is connected to the correct controller.
Analog Output Module Default Status when Wireless Transmission is Interrupted:
If an output module does not receive data from its assigned transmitter for 15 minutes, the red LED on the top of the module will
blink rapidly. If this happens, the individual Analog Output Modules will react as follows:
• Resistance Output Modules (BA/ROM) calibrated for temperature will output the highest resistance in their output range.
• Voltage Output Modules (BA/VOM) calibrated for temperature will set their output to 0 volts.
• Current Output Modules (BA/COM) calibrated for temperature will set their output to 4 mA.
• Voltage Output Modules (BA/VOM) calibrated for humidity will set their output to their highest voltage (5 or 10 volts).
• Current Output Modules (BA/COM) calibrated for humidity will set their output to 20 mA.
• Setpoint Output Modules (BA/SOM) will hold their last value indefinitely.
• Relay Output Modules (BA/RYOM Units Only) will go to their default state (example: open for a normally open unit).
When a transmission is received, the output modules will revert to normal operation in 60 seconds or less.
Possible Problems:
Temperature or Humidity is reading
its low limit or high limit, or the LED
at the top of the Analog Output Mod-
ule is blinking rapidly:
Temperature or Humidity reading is
coming out the wrong output module
Temperature or Humidity reading is
incorrect
Extending the RS485 Network between the Receiver and the Analog Output Modules
The Analog Output Modules may be mounted up to 4,000 feet away from the receiver. The total length of all the shielded, twisted
pair (TSP) cables shown in Fig 13 is 4,000 feet (1,220 meters). Connect the terminals together as shown in Fig 13. If the dis-
tance from the receiver to the group of Analog Output Modules is greater than 100 feet (30 meters), provide a separate power
supply for that group of
Output Modules. BAPI’s
VC350A-EZ Voltage
Conv. and a small
transformer are a perfect
solution.
