Remote-Display/Annunciator
Events
Error Message Probable Cause Corrective Action
ATMAddr Acknowledge Input Fault On An open circuit in wiring from the
ATM-L's "Acknowledge" input
terminal to the associated
annunciator's acknowledge switch.
ATM-L address is Addr.
• Refer to ATM Installation Manual,
P/N 06-236179-002.
• Look for discontinuity in wiring to
acknowledge switch
• Check for missing 10k end-of-line
resistor.
ATMAddr Communication Fault On A communications fault between the
main printed circuit board and the
ATM at address Addr.
• Check the RS-485 wiring from
main printed circuit board Terminal
Block TB15 to ATM Terminal Blocks
TB1 and TB2. Refer to Figures 2-27
and 2-28.
• Check for a discontinuity in the
RS-485 field wiring (Terminal
Blocks TB1 and TB2).
• Troubleshoot wiring to ATM
Terminal Blocks TB1 and TB2 by
breaking-up the circuits to isolate
short circuit to specific leg or legs.
• Check for 24 Vdc power at ATM
Ter mi nal Bl oc k TB3.
• Ensure that the ATM's RS-485
Termination Jumper W1 is set
correctly
• Ensure that the ATM Address
Switch S1 is set correctly.
• Refer to ATM Installation Manual,
P/N 06-236179-002
ATMAddr Drill Input Fault On An open circuit in wiring from the
ATM-L's "Drill" input terminal to the
associated annunciator's drill switch.
ATM-L address is Addr.
• Refer to ATM Installation Manual,
P/N 06-236179-002.
• Look for discontinuity in wiring to
drill switch
• Check for missing 10k end-of-line
resistor.
ATMAddr Monitored Output Fault On An open circuit in any connection
from the ATM to the LEDs (ATM-L) or
relays (ATM-R) being driven
• Refer to ATM Installation Manual,
P/N 06-236179-002.
• Look for discontinuity in wiring to
LEDs (ATM-L) or relays (ATM-R)
• Ensure that the correct supervision
link corresponding to the number
of outputs being used has been
removed
