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 galvani-
cally 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.
