SCR Phase Lock Loop Warning
Description: Phase lock loop circuit PLL LED is ON in SCR-LGA and that System 12 SCR Drive was unable to
lock onto incoming line frequency. PLL LED is normally on for a few seconds during power up. Detected while
the car is not moving. DC controls only.
Car Reaction: Car will not move.
Troubleshooting:
1. Verify PLL indicator is active on SCR-LGA board.
2. Verify iBox is not resetting SCR drive. If so, PLL indicator will be active for a short interval. For a recur-
ring drive fault, iBox should reset SCR drive every 15 seconds. If so, there is probably an underlying fault
the iBox is trying to clear.
3. Contact MCE technical support.
SCR Power Supply Fault, SCR POWER SUPPLY FLT
Description: Indicates that power supplied to the System 12 SCR Drive is insufficient. DC controls only.
Car Reaction: Car will not run.
Troubleshooting:
1. Check all supply voltages on SCR-PS board (See “System 12 SCR Drive” on page 118.).
2. Check F2D fuse. Verify voltages in drive within 1%. Please refer to “Calibrating Actual Car Speed (Sys-
tem 12 SCR Drive)” on page 2-62.
3. If voltages are correct, check drive cable from the iBox to the drive. Check the SCR-LGA board (See
“System 12 SCR Drive” on page 118.).
Secondary Fire Switch On, SEC FIRE SWITCH ON
Description: The Secondary Fire Recall Switch is in the ON position.
Car Reaction: Car will recall to Main fire recall floor, position doors as indicated on Car Operation > Fire Ser-
vice > Fire Code > Fire Recall tab, and await activation of in-car firefighter switch.
Troubleshooting: If in error, check the Secondary Fire Recall switch input.
Security On
Description: Indicates that system security is On.
Security Config ‘n’ (n = 1 - 8)
Description: Indicates the security configuration that is being used.
Send Sys Params to ‘n’ (n = 1 - 15)
Description: Indicates that this controller (iCentral or Local/Dispatcher) is sending system parameters to car
‘n’ (n = 1 - 15). (DO NOT RESET CAR ‘n’).
Serial COP Bus ‘n’ Comm Fault, SCOP BUS ‘n’ COMM FAULT (n = 1 - 4)
Description: Indicates lost communication between the ICE-CTP (cartop processor) board and the ICE-COP
(serial COP) board for at least 1.5 seconds.
Car Reaction: none
Troubleshooting:
1. Check for a bad cable between the ICE-CTP and ICE-COP boards.
2. Check for a bad ICE-COP board.
3. Check electrical noise interference and proper shielding of cables (board to board, board to controller).
Serial COP Bus ‘n’ Inventory Fault, SCOP BUS ‘n’ INVENTORY FLT (n = 1 - 4)
Description: Can indicate lost communication between ICE-COP board and one or more expansion boards or
that an ICE-COP board was connected or disconnected after system powered up (I/O inventory changed).
Car Reaction: none
Troubleshooting:
1. Check for bad cable(s) between the ICE-COP and ICE-COP-x boards.
2. Check for a bad ICE-COP-x board.
3. Press the RESET button on the ICE-COP board (takes a new inventory).
