THRESHOLD Adjustment
1. Move controller handle approximately one (1) inch
(2.5 cm), until LED light comes on.
2. Adjust THRESHOLD trimpot CW to increase function
speed, CCW to decrease speed.
3. Adjust trimpot so that function just starts to move
after LED light comes on.
HI RANGE Adjustment
1. Move handle all the way forward.
2. Back off controller approximately 10°.
3. If function slows down, controller is at or below max-
imum output. If this is satisfactory, do not adjust fur-
ther.
4. If function speed is too slow, turn HI RANGE trimpot
CW to increase speed. If function speed is too fast,
turn trimpot CCW to decrease speed.
5. If necessary, repeat steps (1) through 4.
IRS - RAMP RATE Adjustment
1. Turning RAMP RATE trimpot CW increases the time
to turn ON or OFF; CCW decreases the time it takes
to turn ON or OFF when handle is moved.
2. Trimpot has a wide adjustment range, therefore it
will be necessary to make 2 or 3 turns to notice a dif-
ference in function response.d.
LO RANGE Adjustment (CREEP)
1. Turn CREEP switch on and completely stroke han-
dle.
2. Adjust LO RANGE trimpot for desired output or func-
tion speed. CW increases speed/output, CCW
decreases speed/output.
2.29 BOOM MARKING TAPE INSTALLATION
Boom marking tape installation for Models 100HX, 110HX
and 100HX+10 (110HXER) is shown in Figures 2-28 and
2-29 and Table 2-4.
2.30 BOOM LENGTH/ANGLE SENSOR
ADJUSTMENT PROCEDURES
LOAD RADIUS CIRCUIT CARD P/N-0610106 WAS SUPERSEDED
WITH LOAD RADIUS CIRCUIT CARD P/N-0610130. ALTHOUGH
DIFFERENT IN COMPONENT LAYOUT AND POSITION OF TEST
POINTS, THE TEST POINTS ARE LABELED AND FUNCTION
EXACTLY THE SAME.
NOTE: The boom length/angle sensor is factory set and nor-
mally does not require adjusting unless it is removed
from the base boom for maintenance purposes, etc.
The boom length/angle sensor has been built to
three different configurations, hereafter referred to as
1st generation, 2nd generation and 3rd generation.
1st, and 2nd Generation Radius Cards
100HX, 110HX
1. Length Indicator Adjustment.
a. With the engine running, check test point 10
(TP10). Adjust trimpot P5 until 10 Volts is
obtained on TP10.
b. Fully retract the boom and place in the 0 (+3/-0)
degrees horizontal position.
NOTE: SEE TABLE 2-4 FOR
PROPER DIMENSIONS. NOTE: SEE TABLE 2-4 FOR
PROPER DIMENSIONS.
