Switch-Points

The VSM is equipped with 2 independent potential-free relay switch-points.
These are available as change-over contacts at the connector according to the
pin assignment described in chapter 3.3.2.
Relay R1, R2:
The relays can be independently configured for various switching modes. The
Parameter is used to query and set these switching modes.
Setting T[p1] F[p2]:
In this case 2 pressure thresholds T[p1] (true) und F[p2] (false) are transmitted.
T[p1] < F[p2]: The relay closes when actual pressure falls below threshold T[p1]
and opens again as soon as actual pressure exceeds threshold F[p2].
T[p1] > F[p2]: The relay opens when actual pressure falls below threshold F[p2]
and closes again as soon as actual pressure exceeds threshold T[p1].
