2.3 Remote Mounting
Table 2-3 Remote Mounting Procedure for Durafet II and Durafet III Electrodes
Step Procedure (Refer to Figure 2-4 and Figure 2-5)
1 Apply a thin film of silicon grease to the ID of electronics module’s remote mounting
cavity.
2 Connect Remote Sensor Wiring Cable to the Remote Electronics Housing
a) Remove the cover from the remote cable connector.
b) Align the slots in the cable connector housing with those in the electronics module
and push up to connect the cable to the electronics module.
c) Tighten the locking screw on the rear of the electronics module. Make sure the
connector is completely seated.
3 Secure Electronics Module with Wall, Pipe, or DIN Rail Mounting
Mount bracket with clips facing forward, smaller clip on top and larger clip on bottom.
Wall: Use one of three through-holes to secure to wall.
Pipe: Feed hose clamp through two slots and secure to pipe.
DIN rail: Attach the appropriate DIN rail clip to the mounting bracket:
“U” DIN rail—use metal clip and shorter screw (8 mm)
“G” DIN rail—use gray clip and longer screw (10 mm)
Clip can be rotated for horizontal or vertical DIN rails.
Push electronics module onto the remote mounting bracket until it snaps into position.
4 Connect Remote Sensor Wiring Cable to the Remotely Mounted Electrode
Durafet II with PC Board type connector:
a) Remove cover from the remote cable connector.
b) Loosen the ferrule and slide back the ferrule, small O-ring, and plastic cover to
expose the remote cable connector. Align the cable connector keyway with the
electrode key (small black tab on the top of the electrode). Slide the plastic cover
over the electrode end and hand-tighten the cover onto the electrode. Be careful not
to cross the threads of the connector.
Slide the O-ring and ferrule down the cable to the back of the cover cap. Hand-
tighten the ferrule onto the cover cap.
-OR-
Durafet III with Vario Pin, 11 conductor connector:
Electrostatic Discharge (ESD) hazards. Observe precautions for handling
electrostatic sensitive devices.
a) Remove cover from the cable connector.
b) Make sure electrode connector and cable connector are clean and dry.
c) Align keyway of Vario Pin connector on electrode with tab inside mating connector
on cable. Press cable connector onto electrode firmly.
d) Tighten knurled busing of cable connector by hand to ensure waterproof seal.
