STATUS CODE
DESCRIPTION OF STATUS
CAUSE OF STATUS INDICATION
-11
Start switch closed on power up after initial
key switch closure.
This status code will be displayed when P3 is
greater than 50% of battery volts when the key
switch is closed.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Start switch is mis-adjusted or defective.
•
=
Input voltage at P3 should be less than 50%
of battery volts at key switch closure. Adjust
or replace accelerator unit to insure that the
voltage at P3 is less than 50% of battery volts
before closing the start switch.
Short circuit between P15 and P3 in start switch
input circuit.
•
=
Disconnect wire from P3. Check for short
circuit from this wire to 12V positive.
Resistance should be greater than 4.7K
ohms.
Defective control.
•
=
Disconnect wire from P3. Measure voltage
from P3 to negative. Voltage should be zero.
If not, replace the control.

STATUS CODE
DESCRIPTION OF STATUS
CAUSE OF STATUS INDICATION
-15
Battery voltage is too low at initial key switch
closure.
This status code will be displayed when the
battery volts are less than 68.3 volts at initial key
switch on.

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.
Defective battery
•
=
Check each battery cell for proper voltage (greater
than 1.95 volts at cell). Replace or repair battery.
Incorrect control card adjustment.
•
=
Check Function 15 for proper adjustment for battery
being used. See Handset instruction sheet for
details. Adjust to proper settings.
Check “minimum” battery volts at P1 & NEG.
