Fault Conditions
53
E-51
Brake contactor fault. P8
input on J2 of EC-MCB.
Check input device.
Check setting of parameter F1-01. Verify that setting matches physical
characteristic of break contact.
E-52
Seismic fault. P24 input on J4
of EC-MCB.
Check input device to terminal P24. User defined error message will be
generated for some software versions if programmed by user.
E-53
Smoke detection fault. P21
input on J4 of EC-MCB.
Check input device to terminal P21.
E-55
Safety circuit fault. P6 input
on J2 of EC-MCB.
Check stop switch on top of control cabinet.
Check remaining safety devices.
E-56
Safety circuit fault. P26 input
on J2 of EC-SCB.
Check stop switch on top of control cabinet.
Check remaining safety devices.
E57 Stopping distance error.
Number of pulses exceeds the learned value by more than the pro-
grammable stopping distance error, See “Escalator Braking Distance
Feature” on page 29 .
E58 Stopping distance error.
Number of pulses is less than the learned value by more than the pro-
grammable stopping distance error, See “Escalator Braking Distance
Feature” on page 29 .
E-59 P37 input on J3 of EC-SCB
Check input device to terminal P37. User defined error message will be
generated for some software versions if programmed by user.
