Otis Service Update

(January 2010)
NDC can now offer a comprehensive repair and full-function testing service to the lift industry across the OTIS™ door controllers

The complexity of the unit is the repair issue. The DCSS 5 version is a microprocessor frequency inverter suitable for AC motor applications capable of operating with serial link CAN-bus and CAR-bus communication protocols.


The controller requires setting up parameters in order to control a lift door motor reducing the speed of the motor shaft according to the requirements of the mechanical environment.


The complexity of the unit in terms of hardware and software makes the repair a challenge. However, NDC can now repair and reprogram the unit by using a service tool machine.


NDC can also test those controllers with different door motors.
