Operating instructions – Built-In Encoders, Add-On Encoders and Safety Encoders
1. Remove the screws [34] to disassemble the safety cover [361].
2. Remove the encoder [220], see chapter "Removing EV../AV../XV.." (→ 2 76).
3. In order to remove the ground strap [1489] from the encoder mounting adapter [A],
loosen the serrated lock washer [1496], washer [1497], and screw [1498].
4. Remove the screws [22] to disassemble the fan guard [35].
5. Loosen the screw [1458] to remove the encoder mounting adapter [A].
ð If the encoder mounting adapter cannot easily be removed: Screw an M6
set screw (length 20 – 35 mm) hand tight in the rotor bore. Screw an M8 set
screw (length > 10 mm) into the same bore and push the encoder mounting
adapter [A] off the rotor [1]. Remove the M6 set screw from the rotor bore.
1. Remove the screws [34] to disassemble the safety cover [361].
2. Pull out the cable grommet [269] together with the encoder cable from the safety
cover [361].
3. Loosen the retaining screws [232] and turn the conical spring washers [251] out-
wards.
4. Loosen the screw at the coupling clamping hub [233] at the encoder end, the
screw can be accessed through the slots of the encoder mounting adapter [A].
5. Remove the encoder [220] from the encoder mounting adapter [A] or the interme-
diate flange [225].
1. Mount the intermediate flange [225] to the encoder mounting adapter [A] using
screws [226].
2. Install the encoder [220]; refer to the chapter about installing encoders.
3. Secure the safety cover [361] in place by using the screws [34] and washers [33].
