Sevcon Calibration Tool (Continued)
HOURS COUNTER:
The hours counter records pulsing hours, and is displayed when the calibrator is first plugged in. Once the
SELECT button is pressed, the calibrator reverts to normal operation.
Initially a minute/seconds count is displayed. By pressing the (-) button, hours are displayed
and by pressing the (+) button 1000's of hours are displayed.
Releasing the buttons reverts back to the minute/seconds display. The decimal point blinks every second during
drive. The counter will record up to 65,500 hours before rolling back to 0.
DIAGNOSTIC PROCEDURE:
All machine functions remain operational while calibrator is plugged in.
The last five segments on the bar display are as follows.
BATT
MOTOR V.
MOTOR AMP
TEMP
TEST
With the calibrator connected and the platform powered up, as described in the adjustment procedure. Use the
SELECT button to select the test segment. If the SELECT button is pressed at any time during the test, the test
will be terminated and the minute/seconds count will be displayed.
The first test displayed, on the drive Sevcontrol, is the joystick input. This displays the input as 0-100% as joystick
is moved from min. to max.
Pressing the (+) and (-) buttons step through the tests as shown in
will loop back to the joystick input test, then test 1.

Displays the current battery voltage. Pressing the (+) button displays the highest
voltage, for the machine, that the Sevcontrol has recorded.
Displays the motor voltage as the machine is being driven.
Displays the motor current as the machine is being driven.
Displays the temperature of the MOSFET heat sink in °C. Pressing the (+) button
displays the highest temperature recorded and pressing the (-) button displays the
lowest temperature recorded.
This invokes the diagnostic test routines to check machine switches, joystick,
control wiring etc.
