Adjustment
The limit switch (PNP NO contact; Item 10) for the EAS
®
-HTL
clutch has been adjusted and countered manufacturer-side.
However, as the final clutch position is defined via the
customer-side attachment, re-adjustment may be necessary.
This is carried out as follows:
Loosen the counter nut on the limit switch. Screw in the limit
switch up to its limit (limit switch damped).
Unscrew the limit switch until it switches
(limit switch undamped).
Screw in the limit switch again carefully until it switches (limit
switch is damped again), then continue for another 90°.
Counter the limit switch.
The correct switch adjustment must be checked and
guaranteed by manually disengaging the overload clutch.
In order to secure limit switch function, please
keep it free from oil, grease and other dirt
particles.
