P/N 06-236530-001 5-21 August 2013
ATMAddr Test Lamps Input Fault On An open circuit in wiring from the
ATM-L's "Lamp Test" input terminal to
the associated annunciator's lamp-
test switch. ATM-L address is Addr.
• Refer to ATM Installation Manual,
P/N 06-236179-002.
• Look for discontinuity in wiring to
lamp-test switch
• Check for missing 10k end-of-line
resistor.
RDCMAddr Communication Fault On A communications fault between the
main printed circuit board and the
RDCM at address Addr.
• Check the RS-485 wiring from
main printed circuit board Terminal
Block TB15 to RDCM Terminal Block
TB1. Refer to Figures 2-27 and
2-28.
• Check for a discontinuity in the RS-
485 field wiring to RDCM (TB1,
Terminals 5 and 6 and 7 and 8).
• Troubleshoot wiring to RDCM TB1,
Terminals 5 and 6 and 7 and 8, by
breaking-up the circuits to isolate
short circuit to specific leg or legs.
• Check for 24 Vdc power at RDCM
TB1, Terminals 1 and 2.
• Ensure that the RDCM's RS-485
Termination Jumper W2 is set
correctly.
• Ensure that the RDCM Address
Switch S1 is set correctly.
• Check for duplicate addressed
RDCMs.
RDCMAddr Not Registered On The control unit has not been set up
to expect the RDCM at RDCM RS-485
circuit address Addr.
• Register the RDCM if part of system
configuration. See
Paragraph 3-2.5.2.4.57.
• De-register the RDCM if not part of
system configuration. See
Paragraph 3-2.5.2.4.58.
• Check the 24 Vdc power (TB1,
Terminals 1 and 2) and RS-485
communications wiring (TB1,
Terminals 5 and 6 and 7 and 8)
from the control unit to the RDCM
• Ensure that the RDCM Address
Switch S1 is set correctly.
RDCMAddr PSU Fault On A loss of 24 Vdc power at TB1,
Terminals 1 and 2 or an open circuit
in the RDCM's monitoring circuit from
TB1, Terminals 3 and 4 to the
normally-closed trouble contacts of
its associated remote power supply
• Check for 24 Vdc power at RDCM
Terminals 1 and 2.
• Look for discontinuity in wiring
from Terminals 3 and 4 to remote-
power-supply trouble contacts.
Jumper these terminals if you are
using the ARIES Control Unit to
power the RDCM.
• Check for trouble with third-party
remote power supply
