Adjustment of the limit values (VKM-3..)

With a screwdriver, loosen both mounting screws at the contact.

Move the switch housing to the lowest position.

After loosening the screws, remove the plug cap from the contact.

Connect a suitable multimeter to PIN 1 & 2
(SPDT: contact PIN 2 & 3); (see page 5).

When the instrument is already installed, open the inlet pipe and slowly allow
the medium to flow until the pointer indicator shows the required minimum flow
throughput. The reed switch is then closed (electrical continuity).

Move the switch housing upwards until the reed switch just opens (no electrical
continuity).

At this position tighten the mounting screws. Replace the plug cap. The
instrument is now ready for operation.

By correct adjustment of the limit switch, a bi-stable switch condition is
achieved, i.e.: even when exceeding the adjusted limit value, the contact
remains closed (PIN 1 + 2 or PIN 2 + 3 for changeover contact option).
