Table 7-7. ATM Events
ATM Events
Error Message Probable Cause Corrective Action
ATMAddr Acknowledge Input Fault
On
An open circuit in wiring from the
ATML'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
Terminal Block 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
ATML'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.
• Check for 24 Vdc power at LAM
Board J6.
• 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.
