dicator is standard. The self-locking actuator holds its posi-

tion in a stable manner when idle and in the event of power

supply failure.

3.4 Function

The product controls or regulates (depending on version) a

flowing medium by being closed or opened by a motorized ac-

tuator.

The product is equipped as standard with a mechanical posi-

tion indicator as well as an electrical position and status indic-

ator.

4 GEMÜ CONEXO

Order without CONEXO

If you have ordered the product without CONEXO functionality,

the RFID chip is used for traceability in the production process

and quality assurance. Expansion to include the CONEXO

functionality at a later date must be coordinated with GEMÜ.

Order with CONEXO

option "CONEXO" (see order data).

For electronic identification purposes, each replaceable com-

ponent contained in the product is equipped with an RFID chip

(1). Where you can find the RFID chip differs from product to

product.
