Connect solenoid electrically
→
Always connect the device socket which
was delivered by Buschjost.
!
DANGER
Hazardous electrical voltage
(>25V AC; >60V DC)
There are high risks from elec-
trical voltage during assembly
works.
→
Work on electrical installations may be
carried out by a qualified and authorized
electrician only (refer to section
1.8
).
→
You must connect the earth wire to the
terminal marked with the grounding
symbol
y
.
→
You may only plug the device socket in
de-energized state.
→
Ensure correct polarity while connecting
live wires to terminals marked
+
and
–
.
→
Take care that the insulation is not trapped
in the terminals.
Faulty connection causes risks.
→
After connecting the solenoid carefully
close the terminal compartment to restore
protection.
→
To secure IP65 protection after connec-
ting: Carefully close the device socket.
Check whether the flat seal between
solenoid and device socket is properly
seated. Check whether cable gland is
properly sealed.
→
Connect solenoid in accordance with the
electrical regulations.
→
Use a
round
cable with diameters from
5 mm to 10 mm. The wire cross section
must not exceed 1.5 mm

Commissioning
→
Ensure compliance with the operating
conditions specified in chapter

.
10.1
Checking the switching function
→
Check the switching function of the valve
without fluid prior to flooding the valve and
exposing valve to the operating pressure.
The metallic clicking sound must be heard
during the electrical actuation of the valve.
10.2
Flooding the valve
1. Check whether all connections to pipe lines
are firmly sealed.
2. Slowly increase the pressure to flood the
valve. Thus to prevent pressure hammers.
!
WARNING
To fast flooding of the valve
may lead fluid to escape.
NOTICE
Do not
exceed the maximum operating pressure.
