Operating and installation instructions
Thrust actuator ARI-PREMIO
®
-Plus 2G
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 ARI-PREMIO
®
-Plus 2G 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.

Warning
Orange, yellow or blue LED on the motherboard

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 initialization run is
started.
