2200 SRM 1286
Pick Deceleration
This parameter controls the rate of deceleration
when the coast control switch is released. Increas-
ing the value will increase the rate of deceleration.
Decreasing the value will decrease the rate of decel-
eration. Setting the value at 1 will result in no effect
on the rate of deceleration; the truck will coast until
it comes to a stop.
Battery Full Voltage
This is the battery voltage in millivolts at which the
battery is considered fully charged. Increasing the
setting increases the voltage. Decreasing the setting
reduces the voltage.
Lift Interrupt
This is the battery voltage in millivolts at which the
battery is considered 80% discharged. Increasing the
setting increases the voltage. Decreasing the setting
reduces the voltage.
Troubleshooting
GENERAL
The controllers are sealed units with no serviceable
components. Troubleshooting is usually limited to
accessing status codes and following the diagnostic
procedures listed in the status code charts.
Use standard testing procedures to verify inputs and
outputs when necessary.
CAUTION
Never attempt to probe through the back of
the connector plugs of the motor controller.
The plugs are special sealed plugs.
Probing
through the back of the plugs will destroy the
seal and can cause a short circuit. If a circuit
must be tested for voltage, check for voltage
at an amp-type plug, a switch, or a component.
If a circuit is suspect, check the circuit for
continuity from the front (pin end) of the plug.
Standard probes are too large to be inserted
into the center of the female pins (sockets) of
the special sealed plugs and can expand the
pins. Expanded pins will not provide good con-
nections once the plug is reconnected. The con-
nectors are shaped to allow the insertion of a
flat blade screwdriver into the connector. After
inserting the screwdriver into the connector,
attach probes with alligator clips to the shank
of the screwdriver to obtain readings. An addi-
tional method would be to use a breakout kit.
If the controller detects an issue, a status code is dis-
played on the display panel.
Once the status code number is obtained, follow the
procedures outlined in the status code charts of this
manual to determine the problem.
NOTE:
Due to the interaction of the controller with
all lift truck functions, almost any status code or con-
troller fault could be caused by an internal failure of
the controller. After all other status code procedures
have been followed and no problem is found, the con-
troller should be replaced as the last option to correct
the problem.
Tools and test equipment required are:
• Clip Leads
• Digital Multimeter (20,000 ohms per volt)
• Basic Hand Tools
Check resistance on the proper scale from frame to
power and controller terminals. Resistance of less
than 20,000 ohms can cause misleading symptoms.
Resistance of less than 1000 ohms indicates a short
and should be corrected immediately.
The on-board diagnostic system employed on this lift
truck can assist in the troubleshooting process. Read
and be familiar with the instructions for accessing
and using the dash display diagnostic system.
