2. Slide the solenoid coil onto the armature guide tube of the base valve. The coil
can be adjusted in 45° staggered increments and must be completely en-
gaged.
3. Tighten the solenoid coil back onto the armature guide tube of the base valve.
Tightening torques:
- Metal nut: 0.8 ± 0.12 Nm
- Plastic nut (open): 0.5 ± 0.075 Nm
- Plastic nut (closed with sealing edge): 1.3 ± 0.1 Nm
6.3.2 Connect the solenoid coil
Remove electrical connector
1. Loosen the center screw (see g Fig. 1: 3) on the electrical connector (1) and
remove the electrical connector from the solenoid coil (10).
2. Carefully remove the center screw (3) and seal (2) without damaging the seal
(9).
CAUTION! Cable sealing ring and seal must not be damaged. Liquids and for-
eign objects could penetrate and destroy the device when incorrectly disas-
sembled.
3. Raise the electrical connector insert (8) out of the electrical connector (1) by
inserting a screwdriver into the recess (11).
4. Loosen the cable guide screw (6) and remove the thrust ring (5) and cable
sealing ring (4) without damaging it.
Connect the cable
1. Assemble the cable guide in the order to be followed: Push the cable guide
screw (6), the thrust ring (5), the cable sealing ring (4) and the electrical con-
nector (1) onto the cable. In particular, take the orientation of the thrust ring
(5) into account.
2. The connection terminals (7) are designed with a sleeve terminal design. Con-
nect the individual wires to the connection terminal as shown in the wiring di-
agram. Use wire end ferrules.
Tightening torque: 0.2 ± 0.1 Nm
Assemble electrical connector
1. The electrical connector insert (8) can be mounted in 90° increments depend-
ing on its application. Reinsert the electrical connector insert into the electri-
cal connector (1) until it engages.
2. Screw the cable guide screw (6) back onto the electrical connector without
damaging the cable sealing ring (4).
Tightening torque: 1.8 ± 0.2 Nm
3. Place the center screw (3) and seal (2) carefully into the electrical connector.
Install the electrical connector
1. Place the assembled electrical connector onto the three contacts of the sole-
noid coil (10).
2. Make sure that the seal (9) is lying smoothly between the solenoid coil and
electrical connector.
3. Tighten the center screw (3) with a hex key (SW2) in the electrical connector.
Tightening torque: 0.4 ± 0.1 Nm
