Contact Closure Integration requirements:
-
Two normally open relays
-
750ms momentary pulse commands
-
The lift uses one relay for “extend”, and one relay for “retract”.
-
Make sure that the
BLUE
common wire runs between both relays with a jumper wire
that you supply.
-
When programming your control system, ensure that the relays use a momentary
pulse of 750 milliseconds or more.
-
The relays CANNOT latch. They must function similar to a light switch that always
reverts back to neutral position.
-
Connect the RJ-45 plug of the
Contact Closure Cable
to the Nexus 21 Lift Control
Box using port A1. (Ports A1 and A2 can be used interchangeably.)
A. Connect the Contact Closure Cable

Height Limit Insert
into the Control Box.
Note:
This will set the maximum extension for your system, to reset this,
remove the
Height Limit Insert
