Hoping someone can assist.  Have just had a SL400EVK motor fitted and are trying to install that fail safes (772e) that were supplied with it but with little joy.  I have tried connecting one to the of the devices to 24VDC -/+ and the other to IR1 & GND in a number of combinations but with no joy.  The wiring diagram is not clear to me how these should be connected as the booklet supplied with the fail safes don't seem to reference my gate.

Hoping someone has already completed this and can provide some insight!

Many thanks in advance.
