SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Discharged battery
Check battery voltage to confirm that it is a
minimum of 68.3 volts. Charge battery, if
required.
Battery overcharged or incorrect battery used.
Check each battery cell for proper voltage
(maximum 2.4 volts per cell). If voltage is
excessive, check battery charger for proper
output voltage.
Incorrect control card adjustment.
Check Function 15 for proper adjustment for
