General warnings
It is assumed, for the safe use of the board, that the reader of this chapter is already familiar with the contents
of heading 2.2 "Safety Warnings".

Fault table and fault finding
The faults are shown on the REMP2 display
alternating
the error message “
Er
” with the
number of the identified
fault
. These can be:
•
Recoverable faults
: the lift is still operative and restarts with next call.
•
Non-recoverable faults
: the lift goes out of order and the MP3 board must be reset; the error is deleted in
case of power failure, only faults 23 / 25 / 27 are kept in memory.

Fault origin and actions to be taken
Er - 01
Phase reversal or phase loss
Recoverable
The board makes this control receiving at terminals J2/2(PHA) and J2/3(PHB) the signals PHA,
PHB coming from ACF power supply board.
Verify:
For phase reversal:
•
Swap two of phases R/S/T on the terminal block (then check the rotation of the hoisting
motor and door operator motor).
For phase loss:
verify R/S/T phases on main input terminals.
•
verify R/S/T phases on ACF board terminals.
•
Fuses F1/F2/F3.
•
verify 13 VDC (approx) on the board, relative to GND, at inputs J2/2 (PHA) and J2/3 (PHB).
Note: if it is needed to eliminate the phase control, see heading 4.5 “Other functions on REMP2”.
