Fig 5: Capacitor shafts rotation direction
To find the minimum position, turn the capacitor
shaft in the direction of the arrow, shown in Fig
5.
To find the maximum position, turn the
capacitor shaft opposite to the direction of the
arrow in Fig 5.
At the minimum position, the shaft becomes
stiff; at the maximum position, the shaft
becomes loose.
Do not try to turn the shaft
past these points. If when turning the
capacitor to the maximum position, the shaft
becomes loose, turn the shaft back in until it just
begins to bite, this is the maximum position.
For Vacuum Capacitor AMU (AMU board with capacitor range mod.):
(Applies to all system types) Rotate the vacuum capacitor shaft clockwise as you
look at it from the motor end (see Fig 5) until the shaft just becomes stiff, and then
turn in half a turn. Making sure the motors don’t mesh, drive both motors to
minimum (000).
6b)
For gear driven capacitors:
Re-mesh the gears and tighten motor retaining
screws, ensuring that the motor and capacitor positions don’t move.
For direct drive capacitors:
Loosen the coupling clamp screw on the capacitor
side, turn the coupling on the capacitor side until it lines up wit that on the motor
side ensuring neither the capacitor nor the motor change position at any time. Clip
the coupling together and tighten the clamp screw. Then re-attach the motor plate.
7) Confirm the ‘end of range’ stop functions using the manual drive switches located
on the AMU panel:
Drive C1 positive to the stop position; LED 101 lights; stop point in the range 950-999
