5.6.1 Removal
FIRST REMOVE
CAUTION:
Potential to cause electrostatic damage to electronic
components. Before handling electronic components, ensure that
you are discharged of static electricity by briefly touching a
grounded metal object.
1. Remove Accutronix control panel (subassembly #7).
(See Section 5.1.1.)
2. Remove control module (subassembly #8).
(See Section 5.2.1.)
NOTE: The encoder is a sealed assembly of high-precision
components and not suitable for repair. Should the encoder
fail, it will be necessary to install a factory replacement.
STEP 1
a WARNING: Hazardous Voltage! Turn off all power sources to
actuator before removing encoder assembly. Power sources may
include main power or control power.
CAUTION:
To avoid accidental oil leakage when removing
encoder screws (#1-36), be careful not to remove the encoder
cartridge mounting screw (#14-8). The encoder cartridge screw is
located near one of the encoder mounting screws. Accidentally
removing the encoder cartridge mounting screw could cause oil
leakage into the control compartment. (See Picture 1a.)
Remove the encoder by locating and removing the three
M4 screws (#1-36) that mount the encoder to the actuator
housing. Use a 3 mm hex key to remove the screws.
(Reference Picture 1a to locate screws (#1-36); note
important cautionary statement discussed with Step 1
and 1a).
