Service Test Mode
To assist in the troubleshooting and servicing of the electrical system and related components, a special test mode
allows independent control of the various outputs and monitoring of the various inputs. To enter the service test
mode perform the following step:
1. Turn the key switch to the off position.
2. While holding the Vacuum switch
(C)
depressed, turn the key switch to the on position.
3. Continue to hold the Vacuum switch until the Vacuum indicator turns green.
• Standard models: The Display will show “t” for Test Mode.
• EcoFlex models: The Display will show “svctest”
4. To exit Service Test Mode, turn the key switch to the off position.
Test Mode Input Indicators
Battery Voltage
The battery voltage, as detected by the controller, is shown in the display. If this displayed voltage differs
significantly from the actual battery voltage, it indicates a poor connection between the batteries and the controller.
• On standard models, the LED display
(J2)
will flash out the voltage. For example, “3”, “8”, “-”, “2” represents
38.2 volts.
• On EcoFlex models, the voltage is shown in the display below the “svctest” indicator.
Speed Controller Status
This is a
Main
controller input from the Curtis Drive controller. The indicator is
passed through the Main controller without interpretation, and represents the error
code from the Drive controller.
• On Standard models, the green light in the battery indicator (j5) will light
whenever the key is on. If there is a speed control fault, the indicator will flash
the fault code produced by the speed controller.
• On EcoFlex models, the SCS will be displayed whenever the key is on. If there is
a speed control fault, this indicator will flash the fault code produced by the speed
control.
Refer to the speed control section for details on these codes. If the indicator does
not display, disconnect the Orn/Blu wire from the speed controller and main controller and check the continuity of
the wire. If the wire tests open repair or replace the wire or plug. If wire tests OK, the fault is likely with the Drive
controller.
Forward/Reverse Status
This indicator comes from the Curtis Drive controller, and indicates that the palm drive switch is pressed (either
with or without the reverse button). The indicator is active when the signal is low.
• On EcoFlex models, F/R will be shown in the display.
• On Standard models, the middle battery indicator
(J4)
will be yellow.
Reverse Status
This indicator comes from the Curtis Drive controller and indicates when the reverse switch is pressed and either of
the palm drive switches are pressed (the machine is moving in reverse).
• On EcoFlex models, REV will be displayed if this signal is active.
• On Standard models, the red battery indicator
(J3)
will light.
