TROUBLESHOOTING GUIDE
No Lights/LEDs are Lit.
1. Check for the proper battery supply at terminal block J10 pins 1 and 2.
• J10 pin 1 should be + Battery (12 or 24 volts).
• J10 pin 2 should be – Battery.
• Refer to the “ power supply requirements” section at the beginning of the manual for
cable specifications.
The “ Communication OK” LED is flash-
ing at the rate: second ON/one second
OFF.
1. Does the RS485 communications cable meet specifications. Refer to the “ Communication
with generator control system” section at the beginning of this manual.
2. Check that the RS485 connections are connected properly.
• RS485+ connected to J10 pin 5.
• RS485– connected to J10 pin 6.
• Is the Shield/screen connected correctly.
The shield/screen should be connected at the
Generator end only.
3. Check for proper installation of the RS485 cable between the Annunciator and the genera-
tor’s control panel. Is this cable sharing a conduit or running next to any high voltage or
high current electrical lines?
4. Use the Generator Controller GenLink communication diagnostics to check if data is being
sent or received via the Tx and Rx check boxes. Go to the pull-down menu for diagnostics
and select “ Com Ports” . Select the port the Annunciator is connected to (normally port
0) and look to see if the check boxes change state. If not, data is not being transmitted/
received, check the cabling. If data is being received, check the baud rate settings of all
connected equipment.
The “ Communication OK” LED is flash-
ing at the rate: 0.5 seconds ON/two
