Description 2200 SRM 514
charged or a charged battery must be installed
before lift truck operation can continue. The top
green bar will be illuminated when the battery is
more than 90% charged.
The controller also checks the battery voltage
each time a battery is connected. The traction
control will prevent lift truck operation if the bat-
tery voltage is not correct as set by traction func-
tion 15. A status code of
16 (voltage too high)
or
15 (voltage too low) will indicate on the dig-
ital display. The battery can have a voltage that
is too high or too low. A battery with the correct
voltage can also be deeply discharged from use or
other reasons and have a voltage that is less than
the minimum of the voltage range.
Batteries that have different ampere-hour rat-
ings or are of different ages can sometimes be
used in the same lift truck. It can be necessary
to adjust traction function 14 of the EV-100ZX
motor controller so that the weakest battery is
not damaged. Follow the procedure for adjusting
traction function 14 in one of the following ser-
vice manual sections: EV-100ZX™ SCR Motor
Controller 2200 SRM 557 or EV-T100™ Tran-
sistor Motor Controller 2200 SRM 581.
2. Digital Display. This four-digit LED display is
blank when the lift truck is operating correctly.
The status codes and the hourmeter values are
shown on this display. When the status code In-
dicator is illuminated, the status code is shown.
When the hourmeter and either the hydraulic
motor or traction motor indicators are illumi-
nated, the operating hours are shown. When a
problem occurs, the status code will be shown
with a dash (
) in the left digit position together
with three numbers. The warning LED for the
service interval will also be illuminated when a
problem occurs.
When it is time for periodic maintenance, the
warning LED for the service interval will be illu-
minated and a status code -99 will be indicated.
The traction motor or hydraulic motor indica-
tor will also be illuminated to show which sys-
tem needs maintenance. The register in the con-
troller card must be reset by the service person
before the service interval LED will go OFF.
The digital display for the hourmeter shows the
operating time of 0000 to 9999 hours. The time
for the traction circuit is shown for 4 seconds af-
ter the lift truck has been operating and the key
is moved to the OFF position. The LED indica-
tors for the traction motor and for the hourmeter
will also be illuminated during this time. If there
is an SCR control card for the hydraulic pump
motor, the operating time of the pump motor will
then be shown on the digital display for another
4 seconds. The LED indicators for the hydraulic
motor and for the hourmeter will also be illumi-
nated during this last 4 seconds.
3. Warning LED, Fasten Seat Belt.TheredLED
is ON for 8 to 10 seconds after the key switch is
moved to the ON position.
4. Warning LED, Brake Fluid Reservoir Is
Low.TheredLEDisON for 1 second when the
key switch is moved to the START position and
must go OFF during operation. If the warning
LED is ON during operation, the brake fluid
level in the reservoir is too low.
5. Warning LED, Parking Brake Indicator.
The red LED is ON when the parking brake is
applied and goes OFF when the parking brake
is released.
A buzzer is ON for 8 to 10 seconds if the parking
brake is NOT applied and the seat switch opens
or the key is moved to the OFF position.
6. LED Indicator, Steering Pump Motor.This
LED will illuminate with another warning LED
if the brushes in the steering pump motor are too
worn. If the brush wear sensor is activated in the
motor, the warning LED for brush wear will go
ON and the LED indicator for the steering pump
motor will show that this motor has the problem.
7. Warning LED, Motor Brushes are Worn.
When the sensor for brush wear closes, this
warning LED and the LED indicator for the
motor that has the problem will both illuminate.
The indicator will stay ON until the key is moved
to the OFF position.
8. LED Indicator, Traction Motor.ThisLED
will illuminate with another warning LED if the
traction motor is too hot or the brushes are too
worn. For example, if the brush wear sensor
is activated in the motor, the warning LED for
brush wear will go ON and the LED indicator for
the traction motor will show that this motor has
the problem.
