ADJUSTABLE FEATURES
SX TRANSISTOR CONTROLS
FUNCTION 18 STEER PUMP TIME DELAY
( Push CONT 3 )
This function allows for the selection of steer pump
contactor pick up input, either seat switch or directional
switch closing, as well as the adjustment of the time delay
for the contactor drop out.
• Pick up steer pump contactor on seat switch closure
and drop out steer pump contactor on seat switch
opening, after a delay determined by the following:
Range 1.5 to 65 seconds
Setting Between 0 and 127
Resolution 0.5 seconds per set unit
Example: Setting of 20 = (20 x 0.5) + 1.5 = 11.5 seconds
• Pick up steer pump contactor on directional switch
closure and drop out steer pump contactor on
directional switch opening, after a delay determined
by the following:
Range 0.5 to 63 seconds
Setting Between 128 and 255
Resolution 0.5 seconds per set unit
Example: Setting of 149 = ((149-128) x 0.5) + 1.5 = 11.5
seconds
Note: If the seat switch opens, the steer pump contactor
will open immediately.
FUNCTION 19 MAINTENANCE CODE TENS AND UNITS
HOURS SET
( Push CONT 4 )
This function allows for the adjustment of the tens and
units hours of the maintenance code activation time.
Range 0 to 99
Set 0 to 99
Example 9999 Hours
FUNCTION 20 MAINTENANCE CODE THOUSANDS
AND HUNDREDS HOURS SET
( Push CONT 5 )
This function allows for the adjustment of the thousands
and hundreds hours of the maintenance code activation
time.
Range 0 to 240
Set 0 to 240
Example 9999 Hours
FUNCTION 21 AUTO REGEN BRAKING CURRENT LIMIT
(Push CONT 6)
This function allows for the adjustment of the braking
torque applied when the start or directional switch is
opened, and the counter EMF is above the setting of
Function 5. A higher current correlates to a shorter
stopping distance.
Current = (Value of Setting /4) x 6.5
Note, if the result is less than 52 amps, the control will
default to 52 amps.
FUNCTION 22 NOT APPLICABLE
This value changes with operating mode selected, and
should not be adjusted in the field.
FUNCTION 23 REGEN CANCEL CURRENT
( Push CONT 8)
This function allows for the adjustment of the armature
current at which regenerative braking cancels, and is
specific to each motor design.
Important Note: This function is used to optimize motor
and control performance, and this setting will be
determined by GE and OEM engineers at the time of
vehicle development. This setting must not be changed by
field personnel without the permission of the OEM.
FUNCTION 24 FIELD WEAKENING START
( Push CONT 9)
This function allows for setting the armature current at
which minimum field current will be achieved.
Range 0 to 414 Amps
Setting 0 to 255
Resolution 1.625 per set unit
Example Setting of 20 = 32.5 amps
I FWS = VAL. x 1.625
