LAM Addr COMMUNICATION FAULT On A communications fault between the
Main Controller Board and the RDCM
at address Addr.
• Check the RS-485 wiring from Main
Controller Board J8 to RDCM Board
J8. Refer to Figure 2-41.
• Check for a discontinuity in the
RS485 field wiring to RDCM.
• Troubleshoot wiring to RDCM J8 by
breaking-up the circuits to isolate
short circuit to specific leg or legs.
• Check for 24 Vdc power at RDCM J6.
• Ensure that the RDCM's RS485
Termination Jumper W2 is set
correctly.
• Check for duplicate addressed
RDCMs.
LAM

• Look for discontinuity in wiring from
Terminals 3 and 4 to remote power
supply trouble contacts.
• Check for trouble with third-party
remote power supply.
