1. Check cab console:
a. No power to cab console - check with voltmeter.
b. Upper line (set) is visible but no lower line (out
rate and speed) on display: move to
Communication troubleshooting below.
c. 1 or 10 amp fuse on power cable may be blown.
d. Engage button is not on - check to see if green
indicator light is on.
e. Use Cab Console Power Tester (p/n 27857) to
check power out of cab console. Install tester on
round 7-pin power/comm cable from cab
console. Turn drive on. Green LED shows power
to external controller. Red LED shows power to
solenoid. If LED lights are not lit, double-check
power and connections; replace cab console if
needed.
2. Check communication between cab console and
drive:
a. Check to see if power and communication cable
(main harness) is properly connected.
b. If no lower line on cab console appears (speed
and output rate), and drive will not rotate in
calibration mode, use Cable Continuity Tester
(p/n 27859) to test power and communication to
external controller.
TO PREVENT DAMAGE TO COMPONENTS, DISCONNECT
POWER/COM CABLE FROM CAB CONSOLE AND
EXTERNAL CONTROLLER BEFORE INSTALLING THIS
TESTER.
Install 4-pin test plug on end of 4-pin
power/comm cable before powering the Cable
Continuity Tester - remove before reattaching
power/comm cable directly to cab console.
c. If Cable Continuity Tester shows power is getting
to external controller, turn power off and remove
Cable Continuity Tester and 4-pin test plug from
ends of power/comm cable. Reattach
