8.1. safety instructions
Danger!
Risk of injury from high pressure in the equipment!
• Before loosening the pipes and valves, turn off the
pressure and vent the pipes.
Risk of injury due to electrical shock!
• Before reaching into the device or the equipment,
off the power supply and secure to prevent reactivation!
• Observe applicable accident prevention and safety
regulations for electrical equipment!
Warning!
Risk of injury from improper maintenance!
• Maintenance may be carried out by authorized techni-
cians only and with the appropriate tools!
Risk of injury from unintentional activation of the
system and an uncontrolled restart!
• Secure system from unintentional activation.
• Following maintenance, ensure a controlled restart.

Procedure:
→
Pulse valves (variable code CF 02) as in
connect.
→
For direct current versions connect negative terminal to
terminal 3.
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.

8.2. malfunctions
If malfunctions occur, check whether:
→
the device has been installed according to the
instructions,
→
the electrical and fluid connections are correct,
→
the device is not damaged,
→
all screws have been tightened,
→
the voltage and pressure have been switched on,
→
the pipelines are clean.
Valve does not switch
Possible cause:
• Short-circuit or coil interrupted.
• Medium pressure outside the permitted pressure range.
• Manual emergency actuation locked.
Valve does not close
Possible cause:
• Internal space of the valve is dirty.
• Manual emergency actuation locked.
