What does Mernak 3000 fault code E37 stand for?

Indicates abnormal contactor feedback:

1. When the brake is turned on, the running contactor does not attract.

2. When the elevator runs over 1 s, the contactor feedback model is lost.

3, contactor feedback signal adhesion.

4. After the contactor was closed, no feedback signal was received. ?

Solution: First check whether the brake contactor is in good condition, then tighten the UVW wiring, and check whether the normally open and normally closed parameters of F5-26-28 are set correctly.

Extended data:

Mernak has "integrated" control technology, which is suitable for the main engine of permanent magnet synchronous elevator. Simply put, the inverter is integrated with the elevator control motherboard, which saves the space of electrical components and the control cabinet, reduces the cost, and the operation and maintenance of the control cabinet are relatively simple.

The traditional elevator control system frequency converter and control motherboard are separated, and more wires and electrical components are needed to integrate their functions. Also in Shenzhen, Medis Elevator Co., Ltd. used Munak's integrated control technology on its permanent magnet synchronous passenger elevator and freight elevator, and achieved complete test results.
