Thrust actuator ARI-PREMIO-Plus
5.7 Options
5.7.1 Relay card
Scope of supply:
5.7.1.1 Operating principle
The relay card is a digital expansion module for the PREMIO-Plus control electronics. It has
four relays for signalling system states and positions digitally to a higher-level control or for
connecting relays 1 and 2 to local power consumers (pumps, butterfly valves, etc.).
Two buttons are provided for programming two positions. If a position is overtravelled, the
corresponding travel-dependent relay is switched.
The switching states of the travel-dependent relays are indicated by two LEDs.
ATTENTION !
- The thrust actuator may only be operated for a short time without the hood for
unavoidable setting operations to the electronics, the relay card and the
electrical options. While these operations are in progress, the thrust actuator
has hazardous, live, uninsulated parts exposed as well as moving and rotating
parts.
- Improper execution of the setting operations or lack of care may cause death,
grievous bodily injury or substantial property damage.
- Operation of the thrust actuator without the hood for any purpose other than
that described above is strictly prohibited.

3 Warning
Orange, yellow or blue LED on the
motherboard
4 Failure Red LED on the motherboard
NOTE !
The Failure relay is switched (high) in normal operation.
If a fault occurs, the relay drops out to enable a mains voltage or electronics
failure to be signalled as well.
The relays are not switched if the handwheel is adjusted or an initialisation run is
started.
