2.2. Calibration
Note 1:
Switch actuation can be confirmed using a signal detection device
such as a multimeter or ohmmeter, set for “continuity”.
Note 2:
For NAMUR P+F NJ2-V3-N type sensors, use test meter, P+F model
#1-1350 or equivalent to check sensor actuation and calibration. If the proper
meter is not available, contact the factory for additional assistance with the
test procedure.
Note 3:
Adjust cams by hand by pushing/pulling the cam against the shaft
spring to disengage from the mating spline, rotating to adjust and re-engaging
firmly onto spline.
Required Tools:
Signal detection device (see note 1); slotted screw driver for
cover screws (M4, #10 or 5/16 by model)
Switch Adjustment (two switches):
1.
Remove unit cover as follows: loosen (but do not remove) captive screws,
rotate cover slightly to grip corners, pull firmly.

(#2) actuates.
3.
