4.7 Switch Adjustments
(Figure 4-7 & 4-8)
TILT SENSOR
Function: This limit switch is activated when the
internal sensor in the ‘Tilt Sensor’ is tilted
3 ° or more (factory set at this value). When the Tilt
Sensor activates the elevating and telescope extend
functions will be locked out and an audible warning
alarm will sound. It will activate if the Chassis tilts 3 °
in any direction.
4.7
BOOM REST LIMIT SWITCH
Function: This limit switch is activated when the
Elevating Assembly is fully stowed and
the upper boom is sitting in the boom rest. The Boom
Rest is located on the side of the First Post on the
A38E Work Platform. The high speed drive can only
be operated when this switch is activated. When the
boom leaves the boom rest the Normally Open con-
tacts of the limit switch open and power is cut to the
high speed drive function.
Location: The switch is located on the side of the
First
(see fig 4-8)
Post on the Boom Rest Weldment.
Adjustment:The switch should be activated when the
boom sits in the boom rest. The lever is
adjustable and should be adjusted so that the
switch’s activation/deactivation point occurs just as
Boom 2 leaves the Boom Rest. To adjust the switch
loosen the lever clamping nut and rotate the lever.
Tighten the lever clamping nut. The switch should
periodically be checked for freedom of movement and
be kept clean from dirt and other contaminants that
might affect its free movement.
Adjustment:
1.Place machine on firm level surface ±¼°.
2.Use the Inclinometer
(p/n 057281-000) to ensure front and rear of
Chassis is level ±¼°.
3.Attach a 1 meter length of single core wire
to the “Reset Port” shown in Fig 4-7.
4.Attach the other end of the Single core wire
to the a negitive terminal on a battery cell and
hold for 3-4 seconds until a green LED flashes
from under the head of the Tilt sensor.
5.Test the Sensor as described below before
using the machine.
1.Raise the platform approximately 2 )t f 7 ( m
2.Support the elevating assembly (see “Sup-
porting Elevating Assembly” on
page Section 4-7).
3.Jack the machine to the side (Past 3 degrees)
and the tilt alarm should sound..
Test:
Location: The Tilt Sensor is fitted in the rear chassis
alcove and is a vital part of the electrical
equipment.
