Check cable connections from T1, T2, T3 to
motor terminals. Check control input connec-
tions to A1, A2. There is a delay of 0.5s
(approx.) until ramping starts, after applying
control voltage.

connected, ensure that PTC terminals P1, P2
are connected to each other with a loop. If
motor PTC is connected, motor may have
over-heated. If motor has not over-heated,
PTC sensor may be faulty.
[Ø LOSS] is ON
Missing phase voltage. Check power cable
connections to L3. If either L1 or L2 is missing,
[POWER ON] and [Ø LOSS] LEDs will be OFF.
[WRONG Ø] is ON
Incorrect phase sequence. Change the termi-
nal position of two of the power supply
cables connected to L1, L2, L3.
Alarm
Any alarm LED is ON
After noting type of alarm, disconnect mains
activated
supply L1, L2, L3. Re-connect only if problem
has been resolved. This resets device.
Note: Monitoring of phase loss and phase sequence is carried out just
after supply L1, L2, L3 is applied and thereafter it is de-activated
