NOTE!
Important information:
▶
Avoid emitting pulses simultaneously to both coil windings.
▶
Do not switch any other consumers (relays, etc.) at the same
time as the terminals.
▶
The coil connection, to which voltage is not applied, must be
galvanically isolated (open).
▶
If two or more valves are switched in parallel, ensure that this
requirement is met by using 2-pole or multi-pole switches.
