Limit Switches for Pneumatics
Installation and setup instructions
for limit-switch box by KINETROL …
-003U Ex ed IIC T6 and
… -004U
IMPORTANT
If the limit-switch box … -003U is delivered separately, it has to be
stored in a plastic bag until it will be installed.
The certification will keep its validity only if the limit-switch box has
been installed correctly on the swivel drive.
For indirect installation, the limit-switch box can be supplied, on
customer's request, with installation dimensions according to VDI/
VDE 3845 or according to KINETROL’s factory norm (see below).
Direct installation

Unscrew the cover of the supplied limit-switch box and pull it
off, as shown in the illustration, while pushing down the
limit-switch shaft. Caution: Do not lose the cover sealing!

Remove shaft mounting bracket by opening the screws and
take off the limit-switch shaft.

Clamp swivel drive in vise (use soft jaws)

Apply LOCTITE (or a similar adhesive) on mounting thread, put
on the supplied cork sealing and attach the bottom part of the
limit-switch box. Fix it using the screws supplied.

The two trip cams on the limit-switch shaft are fixed by one
screw each. Untighten these screws.

Place limit-switch shaft with the Allen key onto the upper four
cornered shaft of the drive or the spring lock unit. DO NOT
HAMMER – DO NOT APPLY FORCE!

Install shaft mounting bracket again.
Adjusting the trip cams

Set revolving wings of the swivel drive to the initial position.
Caution: The mechanical end stops of the swivel drive should
have been set already to make subsequent correction of the
trip cams superfluous.

Move the respective trip cams on the guide ring until a soft click
indicates that the contact of the micro push-button (… -3U) or
micro push-button (… -4U) has switched. To be on the safe
side, move the trip cams by about 2-3 degrees further and
tighten the clamping screw.

Move revolving wings to the opposite stop position. Com-
pressed air is needed for single-acting swivel drives with spring
lock unit.

Proceed accordingly with the second trip cam.
