Configuration and Troubleshooting
2-70 Manual # 42-02-2P26
Floor Code Invalid (311) An invalid (out of range) absolute floor code has been detected.
On a stepping landing system: Check spare inputs (R0, R1, R2, etc) to
ensure they are returning valid binary floor codes. Refer to landing sys-
tem drawing in controller job prints.
On an LS-EDGE landing system this fault may require performing the
hoistway learn procedure to re-learn the floors.
Floor Unintended Motion (252) Traction 0nly. The car has drifted more than six inches from the landing
with car and hall doors open. The emergency brake will deploy. Fault-
bypassed in Construction.
Correction:
1. If persistent, verify landing system sensors and connections.
2. Verify machine brake and counterweighting.
3. With car on inspection, press UIM RST on SCE-CPU board for 8 sec-
onds to reset brake.
4. Press FLT RST to reset faults.
FLT BYPASS JP (264) The fault bypass jumper on the SCE-CPU board is in the BYPASS position.
Cannot be bypassed.
Flt Bypass JP: Time Out (265) The fault bypass jumper on the SCE-CPU board is in the BYPASS position
and will be effective for the duration of the countdown timer displayed.
When the timer expires the system will ignore the jumper and Fault
Bypass will end. If more time in fault bypass is required, cycle power to
the controller to “reset” the jumper or temporarily move the jumper to
the OFF position before again placing it in the BYPASS position.
GOV Input Low (164) Traction 0nly. The governor input is low. The car will perform an emer-
gency stop, immediately dropping motor and brake contactors. Cannot
be bypassed.
System Verifies:
- Application is a Traction machine and the GOV input is low
Correction:
1. If in error, verify governor and input mechanically and electrically.
2. If actual, troubleshoot for overspeed and/or check governor overspeed
switch.
GS Open-Running (336) Asserted if the car gate switch is not made during a run. The car will
make an emergency stop.
Correction:
1. Verify GS input electrically and mechanically.
Hall Calls Bypassed (355) Hall calls are being bypassed. Typically due to heavy load status of car.
Correction:
Automatically corrected when car load allows additional passenger.
1. Verify System IO > Programmed Inputs > Load Hvy.
Hall Calls Disabled (354) Hall calls have been disabled. Typically due to heavy load status of car.
Correction:
Automatically corrected when car load allows additional passenger.
1. Verify System IO > Programmed Inputs > Load Hvy.
HDB Switch Fault (329) Generated when HDB and HDBO inputs are in the same state (both low
or both high) indicating possible failure of Hoistway Door Bypass Switch.
Correction:
1. Toggle hoistway door bypass switch and verify that diagnostic LEDs
HDB, HDBO also toggle (System IO > System Inputs).
2. Verify HDBPTST jumper is inserted in the OFF position.
