DUAL MOTOR IN-BOARD WHEEL REVERSAL - This feature allows for the control of the in-
board traction motor while in a sharper turning condition. The in-board motor is controlled by inputs
from limit switches located on the rear steering wheel which connect card input points to negative.
Logic for turn switch operation is shown below:
LEFT TURN - L1 and L2 open - motor energized.
- L1 closed and L2 open - motor disabled.
- L1 and L2 closed - motor reversed from normal direction.
RIGHT TURN - R1 and R2 open - motor energized.
- R1 closed and R2 open - motor disabled.
- R1 and R2 closed - motor reversed from normal direction.
DUAL MOTOR SHARP TURN SPEED LIMIT - This handset adjustable feature allows for the
limiting of top speed when either the R1 and R2 or the L1 and L2 switches are both closed.
TOP SPEED ( MOTOR VOLTS ) LIMIT - This feature provides a means to limit motor volts to
three adjustable limits by limit switch opening between input points on the control card and negative.
The lower motor volt limit always takes priority when more than one switch input is closed. This
motor volt limit effects top speed of the SCR, but actual truck speed will vary at any set point de-
pending on the loading of the vehicle. Each speed limit is adjustable by the handset, function 11, 12,
and 13, for speed limits 1, 2, and 3.
STEER PUMP CONTACTOR TIME DELAY - This feature provides two options for SP time
delay option 1 provides a .5 to 63 second time delayed drop out of the steer pump contactor when the
Forward or Reverse directional switch is opened. This is overridden by a 1.5 second time delayed
drop-out whenever the seat switch is opened. Option 2 provides a .5 to 63 second time delayed drop
out of the SP contactor when the seat switch is opened.
CONSTANT CURRENT COIL DRIVERS AND INTERNAL COIL SUPPRESSION - This
feature allows the use of 24 volt contactor coils on through the entire voltage range of the EV100 (
24 volts to 84 volts ) for the F,R,1A,SP,RG,D,and FW contactors.
This feature also allows the above contactors to operate cooler due to less current being applied to
the coil after pick-up.
HOUR METER READINGS - This feature will display the recorded hours of use of the traction
control and pump control to the dash display each time the key switch is turned off.
INTERNAL RESISTANCE COMPENSATION - This feature is used when the Battery Discharge
Indicator is present. Adjustment of this function will improve the accuracy of the BDI.
TRUCK MANAGEMENT MODULE (TMM1) - is a multi-function accessory card that provides
the OEM the ability to provide status codes or operator warning codes that will be displayed on the
dash display whenever a normally open switch or sensor wire provides a negative signal to the card.
Typically the TMM1A can be used to display over temperature of motors, hydraulic systems or any
other switch that closes at the desired temperature. The TMM1A can also be used to monitor and
display motor brush wear warnings when the motor brushes require replacement.
