3.2 Non-NAMUR Mounting
For non-Namur mounting (Fig. 7), depending on the
application the mounting kit will usually consist of a
bracket and one or two adapters. Fit the bracket to the
actuator/Valve. Fit the bottom adapter to the actuator. If
two adapters are supplied, fit the top adapter to the bottom
adapter. For valves, fit the handle in conjunction with the
bottom adapter. Lower the Switchbox onto the bracket and
lift the (top) adapter until it mates correctly with the
Switchbox shaft. Secure adapter to Switchbox shaft using
grub screw, if there is provision. Once the Switchbox and
actuator/Valve shafts are correctly aligned, tighten all the
bolts. All bolts and washers should be supplied with the
Mounting kit.

Removal of the Cover
Turn the HYVISION COVER (Fig. 8) until the Arrow lines
up with the Arrow moulded into the base. This action will
release the cover from the three bayonet grooves in the
base. The cover may be tight to turn initially due to the
friction on the 'O' ring seal.
5
Setting the switches
Each Switch has its own independent operating cam
arrangement. Setting is done by simply pushing the Cam
(Fig. 9) against the spring (to disengage from the Spline)
and turning the Cam until the Switch is activated. Once in
the correct position, the Cam is pushed back onto the
spline. To set the other Cam, first operate the actuator to
the opposite end of its travel and adjust in the same
manner as above.

Checking the switch setting
Operate the actuator fully in both directions several times
to check that the Switches are operating correctly.

Switch / Terminal strip assembly
removal
The whole Switch/Terminal Assembly can be removed in
one piece for ease of wiring, if required. This is done by
removing the locking screws in the base.
