UAL MANIPULATOR
With the calibrator
- Connect the calibrator (Ref. 622813) to the variable speed drive: see
Chapter CHECKING THE OPERATION FO THE SEVCON VARIA-
BLE SPEED DRIVE , paragraph USING THE CALIBRATOR .
- Climb into the platform's basket with the calibrator.
- Select menus 2-4-2 and 2-4-4 (UPPER BOX TEST) on the calibrator
and note the voltage values from the signals from the manipulator.
- Then select menus 2-3-17, 2-3-18, 2-3-19 and 2-3-20 (UPPER BOX
PERS) on the calibrator to adjust the limit values for the voltages deli-
vered by the manipulator.
- Lastly, select menus 2-4-1 and 2-4-3 (UPPER BOX TEST) on the
calibrator and check :
- That the proportional signal shows a good progression (i.e.
0 to 100%).
- That it shows 0% in Neutral and 100% only when the mani-
pulator arrives almost at the limit switch.
This procedure must be performed every time
the manipulator is replaced.
With a voltmeter
- Take the voltmeter and climb into the access platform's basket.
- Remove and open the basket console 5 (Fig. B1) (4 bolts, No. 4 hex
spanner) and then locate the wires:
- Connected to the manipulator 6 (Fig. B1 - B2) (Trans
Steering).
- Connected to the manipulator 7 (Fig. B1 - B3) (Turret rotation
+ Upper arm).
