OVERHEATING PROTECTION
· Two clixon sensors are added in the motor winding to measure the
temperature and protect the motor against overheating. The signals of these
sensors are connected in a 2-conductor terminal strip:
The motor thermal protection 1 is the clixon sensor that indicates the
motor is near to reach the critical temperature. In this case the lift
controller must stop the car at a landing to alow the passengers to leave.
The motor thermal protection 2 is the clixon sensor that indicates the
motor has reached the critical temperature. Then the lift controller has
to remove the ECC + 230 V supply voltage.
The maximum contact rating is 7.0 (2.0) A 250 Vac.
DOOR CONTACT
· A separate monitoring signal is necessary to check that the car door(s)
is/are in the closed position. To comply with this point an additional door
contact is added, and the signal has to be connected to the lift controller.
The maximum contact rating is 2 A 230 Vac.
