82 CNT Short Circuit
This error is reported if the contactor feedback input is
still on [CNT=1] while the lift is in motion. Check CNT
terminal, contactor aux. contacts and their wiring.
Cause
Troubleshooting
1. CNT is a single line with 230VAC connected to the main board
CNT (for L) CNN (for N). Neutral is directly connected. CNN
is a single phase moving through the K1-K2-KF contactors in
traction lifts with the CNT B50 parameter set as 1 or KM-KD-
KS when it is used for hydraulic lifts and parameter B50 is set
equal to 2. If one of these contactors do not activate proper,
then CNT error is given to the board. check if all coils activate
properly.
2. Check if the board have voltage 230 in rest position. if not, then
check the auxiliary contacts of these contactors.
3. If there is voltage in rest position but the error appear then
contact after sales service department.
