CHECK
• While steering or lifting up, the voltage measured at
the System Module's P terminal did not agree with
the predicted value for at least 240mS. This issue may
be caused by a power wiring error or an internal fault.
• Pump Feedback . Predicted >7V
• ZAPI - HEALTH (Status LED) - ON
• While steering or lifting up, the voltage measured at
the System Module's P terminal did not agree with
the predicted value for at least 1000mS. This issue
may be caused by an open-circuit of the pump wiring
(+BF2 and –P terminals) or an internal fault.
• Pump feedback does not increase more than 1.3V
• Pump feedback is less than 20% Battery Voltage
• Battery Voltage - pump feedback is greater than 4V
• ZAPI - HEALTH (Status LED) - ON
• The System Module detected excessive braking cur-
rent for more than 5000mS. This can be caused by
transporting an excessive load on a steep grade.
Alternately, this may indicate an internal fault.
• ZAPI - HEALTH (Status LED) - ON
• The System Module voltage at the F1 and F2 termi-
nals was improper at power-up (expected to be ½
Battery Voltage). This is caused by an open- or short-
circuit in the field wiring or motor. Disconnect the
field and motor wiring from the System Module and
connect F1 / F2 with a short wire. If the situation per-
sists after a power cycle, it may be an internal issue.
• ZAPI - HEALTH (Status LED) - ON
CHECK
• Calibrate the tilt sensor, see Section 5.2.
• Replace then calibrate tilt sensor, see Section 5.2.
• Check tilt sensor connections and wiring in ground
control box.
• Calibrate the tilt sensor, see Section 5.2.
• Replace then calibrate tilt sensor, see Section 5.2.
• Refer to Section 2.3: Troubleshooting in the LSS man-
ual, 3124288.
