This manual shows only the parameters that have an operational relevance to the ICON32. The UIT may have
additional parameters available, which should not effect the controller operation.

1161

DZ Node B data error.

—

1166

Low Pressure Active On Inspection - INHIBIT DOWN RUN

—

1167

PU #3 - Electronic MCFC Fault

—

1169

Auxiliary Power Unit Relay Monitor Fault.

1170

Low Pressure Active On Inspection - INHIBIT DOWN RUN

—

1501

MCD failed to open - A run sequence was started and was
waiting for MCD input to go active. The MCD input did not
go active at the start of a run.

—

1502

MCE dropped during run - MCE went active at the start of a
run, but during the run, a loss of MCE was detected.

—

1520

The CANBus channel is turned Off.

—

1521

CAN Channel 1 did not communicate.

—

1522

CAN Channel 2 did not communicate.

—

1523

CAN Channel 3 did not communicate.

—

1524

Invalid CAN handle.

—

1526

CAN Channel 1 did not receive a message for 60 sec.

—

1527

CAN Channel 2 did not receive a message for 60 sec.

—

1528

CAN Channel 3 did not receive a message for 60 sec.

1529

The controller has not received CAN data from the drive in
0.4 seconds. The safety string opens, stopping all car
motion.

Software error.

1530

TSR overspeed detected - The monitoring input for the Fast
Valve Solenoid (UFSM) has been seen as active when the
selector/car is in a terminal floor zone and on the TSR tape
magnet. The TSRCPU output is turned off, stopping all car
motion.

• Use the TFR Command to reset.
• Cycle operation to inspection and back to automatic. This

fault indicates a timing issue with hardware on the IOF Card.
Check all connections and verify no added relays to sole-
noid outputs. Slowdown magnet length wrong, valve mis-
adjusted (not enough slowdown), P17 value too low.
Should this continue to happen, replace the IOF Card.

1531

Valve input monitor failed - Valve monitoring inputs UFSM,
USSM, DFSM, or DSSM have been detected in the wrong
state (should always match their output counterparts UFS,
USS, DFS, or DSS). The TSRCPU output is turned off, stop-
ping all car motion.

• Use the TFR Command to reset.
• Cycle operation to inspection and back to automatic. This

1532

TSR input monitor failed - The TSRM monitoring input does
not match the TSR output. The safety string is opened, stop-
ping all car motion.

• Use the TFR Command to reset.
• Cycle operation to inspection and back to automatic. This

fault indicates a timing issue with hardware on the IOF Card.
Check all connections and verify no added relays to sole-
noid outputs. Should this continue to happen, replace the
IOF Card.

1533

FPGA detected door open outside of door zone - The safety
string opens, stopping all car motion.

• Use the TFR Command to reset.
• Cycle operation to inspection and back to automatic. This

fault indicates a timing issue with hardware on the IOF Card.
Check all connections and verify no added relays to sole-
noid outputs. Should this continue to happen, replace the
IOF Card.

1534

FPGA detected an active fast valve solenoid (UFS or DFS out-
puts energized) when on hoistway access, inspection, or lev-
eling -The safety string opens, stopping all car motion.

• Use the CLR FLT button to reset.
• Cycle operation to inspection and back to automatic. This

fault indicates a timing issue with hardware on the IOF Card.
Check all connections and verify no added relays to sole-
noid outputs. Should this continue to happen, replace the
IOF Card.
