Procedure:
→ Pulse valves (variable code CF 02) as in “Fig. 8: Circuit diagram”
connect. Pulse to Terminal 1 closes the valve; pulse to Terminal 2
opens the valve.
→ Connect standard version L1/+ or N/– to Terminals 1 and 2 irre-
spective of the polarity.
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 gal-
vanically 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.
Electrical connection of the position indicator (var code LF02 or
LF03) see operating instructions Type 1060.
6 MAINTENANCE, TROUBLESHOOTING
6.1 Safety instructions
DANGER!
Risk of injury from high pressure in the equipment.
▶ Before loosening the pipes and valves, turn o the pressure and
vent the pipes.
Risk of injury due to electrical shock.
▶ Before reaching into the device or the equipment, switch o 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 technicians 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.
