10.2.11 Current Sensors
To remove or reinstall the current sensors, use the
following steps. Refer to
NOTICE
PARTS TYPE
Some current sensors look different than the sensors
shown in this guide. LEM is the manufacturer of current
sensors used in production since the first quarter of
2016. Previously, Honeywell manufactured the current
sensors.
Disassembly
1.
Remove the power terminal mounting plate. Refer
to
chapter 10.2.9 Power Terminal Mounting Plate
.
2.
Disconnect the wire harness from the wire
connector on each of the 3 current sensors.
3.
Remove 6 screws (T20), 2 from each of the 3
current sensors.
4.
Remove the current sensors from the drive.
Reassembly
Tighten fasteners according to
, unless otherwise noted.
1.
Position the outer 2 current sensors at the top of
the power terminal mounting plate with the
current sensor base against the plate.
2.
Invert the middle current sensor so that the wider
base is at the top.
3.
Align the current sensors so that the cable
connectors face the back of the unit, and the
arrows on the sensors point outward.
4.
Attach the 3 current sensors to the power
terminal mounting plate by fastening 6 thread-
forming screws (T20), 2 per sensor. Torque screws
to 2.0 Nm (17.7 in-lb).
5.
Connect the current sensor cables to the 3 cable
connectors on the current sensors, 1 per current
sensor.
6.
Attach the 16-pin connector to MK101 on the
power card, and route the current sensor cables
through the cable guides on the power terminal
mounting plate.
7.
Replace the power terminal mounting plate. Refer
to
chapter 10.2.9 Power Terminal Mounting Plate
