E-2 Detector Check
2.1 Applicable Model: GR-750XL-2
2.1.1 Boom Length Detector
1. Retract the boom fully, set the boom angle to 0°,
and set the PTO switch to "OFF."
2. Measure the resistance of the potentiometer.
Checking at the connector of the detector
Pull out the connector(CN576) of the detector, and
measure the resistance of the potentiometer.
The specified resistance values are as follows:
G-R: 833±167
Ω
G-W: 458±92
Ω
Checking at the connector of the AML
[NOTICE]
Be sure to pull out the swing angle detector
connector (CN580) in advance.
Pull out the CN3 connector (CN643) of AML, and
measure the resistance of the potentiometer.
The specified resistance values are as follows:
1-5: 833±167
Ω
2-5: 458±92
Ω
