Step 1
- De-energize the device.
- Remove the screw cap.
- Using a suitable screwdriver (with as wide a blade as possible), remove
the screws at left and right of the profibus module.
Step 2
To help pull out the module, connect the device lead (or other suitable line)
directly to the terminals (Fig. 1).
Step 3
Carefully lift the basic module up and out of the housing. Be sure that at the
lower section of the module the ribbon cable for connecting the sensor to a plug
connector remains attached.
Turn the basic module to the side. While doing this, avoid putting any tension on
the connecting lead to the sensor (Fig. 2-3).
Step 4
Disconnect the sensor connecting lead from the basic module (plug connector)
(Fig. 4).
Caution: Avoid touching the plug connector at the bottom of the basic module
with your fi
ngers since dirt (grease, moisture) and electrostatic discharge could
damage the device. The sealing washer below the basic module can remain in
the device housing.
