Fault Conditions
Both the controller and the VVVF drive (if used) will display fault condition codes. This section
contains complete controller and drive fault condition tables and descriptions.
Controller Faults
Note
To reset a latched fault, press both UP and DOWN buttons and hold them down for two sec-
onds.
Terminals P10 through P18, P20, and P21 on the EC-MCB and terminals P27 through P34 on
the EC-SCB are assignable to different functions. The following table lists faults for these termi-
nals as they are normally assigned by MCE. There is a generic table following this one with
spaces to write the devices monitored by your system if changes have been made or your system
does not conform to the standard.

Fault Description Troubleshooting
E-01
Reversal detection fault on
EC-MCB. S2 and S3 input on
J1 of EC-MCB.
Confirm that F4-08 is set to the same value as UPNP when escalator is
going UP. If not, refer to the Escalator Learn Operation to re-learn
Verify that sensors are spaced < 1/2 tread width apart.
E-02
Overspeed fault. Step Speed/
Missing Step monitoring
using upper sensor 1. S2
input on J1 of EC-MCB.
Check connection and function of input device.
Confirm that F3-01 is set to the same value as USP1. If not, refer to
the Escalator Learn Operation to re-learn parameter F3-01.
Check escalator mechanical integrity.
E-03
Overspeed fault. Step Speed/
Missing Step monitoring
using upper sensor 2. S3
input on J1 of EC-MCB.
Check connection and function of input device.
Confirm that F3-02 is set to the same value as USP2. If not, refer to
the Escalator Learn Operation to re-learn parameter F3-02.
Check escalator mechanical integrity.
E-04
Overspeed fault. Left handrail
speed monitoring. S4 input
on J1 of EC-MCB.
Check connection and function of input device.
Confirm that F3-03 is set to the same value as USP3. If not, refer to
the Escalator Learn Operation to re-learn parameter F3-03.
Check escalator mechanical integrity.
E-05
Overspeed fault. Right hand-
rail speed monitoring. S5
input on J1 of EC-MCB.
Check connection and function of input device.
Confirm that F3-04 is set to the same value as USP4. If not, refer to
the Escalator Learn Operation to re-learn parameter F3-04.
Check escalator mechanical integrity.
E-06
Underspeed fault. Step
Speed/Missing Step monitor-
ing using upper sensor 1. S2
input on J1 of EC-MCB.
Check connection and function of input device.
Confirm that F3-01 is set to the same value as USP1. If not, refer to
the Escalator Learn Operation to re-learn parameter F3-01.
Check escalator mechanical integrity.
E-07
Underspeed fault. Step
Speed/Missing Step monitor-
ing using upper sensor 2. S3
input on J1 of EC-MCB.
Check connection and function of input device.
Confirm that F3-02 is set to the same value as USP2. If not, refer to
the Escalator Learn Operation to re-learn parameter F3-02.
Check escalator mechanical integrity.
E-08
Underspeed fault. Left hand-
rail speed monitoring. S4
input on J1 of EC-MCB.
Check connection and function of input device.
Confirm that F3-03 is set to the same value as USP3. If not, refer to
the Escalator Learn Operation to re-learn parameter F3-03.
Check escalator mechanical integrity.
E-09
Reverse phase fault. P9 input
on J2 of EC-MCB.
Check input device to P9 terminal. May be used for Speed Governor or
Motor Efficiency Controller depending on configuration.
