Manual

note!
Caution risk of breakage!
• Do not use the coil as a lifting arm.
→ Body with welded sleeve: Use PVDF.
→ Body with bonded sleeves: Use Tangit special adhesive.
Valve body must not be installed under tension.
→ Observe direction of flow:
The arrow on the body indicates the direction of flow (no function
in opposite flow direction).
6.4. Manual emergency actuation
Caution!
Discharge of medium due to loss of the O-rings!
• If the O-rings are lost, the valve will leak. Medium may be
discharged.
note!
Caution!
• When the manual emergency actuation is locked, the valve can no
longer be actuated electrically.

6.5. Electrical connection of the cable plug
Warning!
Risk of injury due to electrical shock!
• Before reaching into the device / equipment switch off the power
supply and secure to prevent reactivation!
• Observe applicable accident prevention and safety regulations for
electrical equipment!
If the protective conductor contact between the coil and body is
missing, there is danger of electrical shock!
• Always connect protective conductor.
• Check electrical continuity between coil and body.
Authorized cable plug e.g.
Type 2508 or other suitable
cable plug in accordance with
DIN EN 175301-803 Form A
Seal
max. 1 Nm
Note the voltage and current type as specified on the type
label.
Procedure:
→ Tighten cable plug (for permitted types see data sheet), observing
max. torque 1 Nm.
→ Check that seal is fitted correctly.
→ Connect protective conductor and check electrical continuity
between coil and body.

The connection terminals in the cable plug are identified with
the numbers 1 to 3 according to the terminals on the valve.
Procedure:
→ Connect the pulse valves (variable code CF 02).
→ 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 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.
7. MAINTENANCE, TROUBLESHOOTING
7.1. Safety instructions
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.
7.2. Malfunctions
If malfunctions occur, check:
→ 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.
