5.6 Switchpoints

The VSM provides 2 independent, potential-free relay switchpoints. These are
available as change-over switches at the connector according to the pin assi-
gnment described in section 3.3.2.
Relay R1, R2:
The relays can be configured independently for various switching modes. The pa-
rameter is used to query and set these switching modes.
Setting T[p1] F[p2]:
In this case 2 pressure thresholds T[p1] (true) and 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].
