STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-02
Standard truck configuration where the
direction is set by accelerator volts –
forward direction selected on power up.
This status code will be displayed when voltage
at P7 is less than 1.9V.
MEMORY RECALL
NO
CORRECTIVE ACTIONS TROUBLE-SHOOTING DIAGRAM
Circuits valid

Controller
SYMPTOM
Control will not operate because of Static Return
to Off (SRO) lock out.
POSSIBLE CAUSE
Accelerator calibration is incorrect and it must
be recalibrated for a new accelerator pot
installation.
· Repeat the accelerator pot calibration routine
outlined in this operating manual
The voltage at P9 is less than 4.2V.
· Measure the accelerator pot to verify that it
reads above 3K ohms. If not, replace the
accelerator pot.
Defective control.
· Replace the controller unit.

STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-02
Optional truck configuration with directional
switch input - forward directional switch is
closed on initial power up.
This status code will be displayed when P4 is
greater than 60% of battery voltage at initial key
switch on.

SYMPTOM
Control will not operate because of Static Return
to Off (SRO) lock out.
POSSIBLE CAUSE
Forward directional switch is closed on initial
start up (i.e. closure of battery, key switch or
brake switch).
· Return directional switch lever to neutral and
then return lever to forward position.
Forward directional switch is welded closed or
mis-adjusted to be held closed.
· Replace or adjust directional switch to insure
that it opens when the directional switch is
returned to neutral.
Short circuit between B+ and P4.
· Disconnect the wire from P4 and check for
positive voltage. Correct source of voltage.
Defective control. Replace the controller unit.
