Slow Motion Control Module; Changing The Manual Slow Motion Control Module For The Dec. Motor Module - Vixen AP Equatorial Mount Instruction Manual

APPLICATION
Case 2: Changing the Manual Slow Motion Control Module for the DEC. Motor Module.
1
Remove the declination body cover.
Open up the polar scope window on the declination body by sliding
down the shutter. While pushing down on the hook on the bottom of
the declination body, pull out the declination body cover by pinching the
hook and window hole with fingers.
2
Remove the batteries from the declination body. Do not disassemble the mount without removing the batteries. This may cause damage.
3
Loosen the two socket head cap screws on the top of the declination
body as shown in the figure with the 4mm Allen wrench. Remove the
manual slow motion control module assembly. Be sure to hold the
manual slow motion control module assembly firmly in hand while
loosening the screws.
Note:
The internal joint electrical contact of the declination body is very
delicate. Take care not to touch with fingers or other objects.
4
Separate the manual slow motion control module from the mount
head unit. Loosen the three socket head cap screws on the manual
slow motion control module as shown in the figure with the 3mm Allen
wrench.
5
Attach the DEC motor module onto the mount head unit so that the
sunken portion on the DEC motor module (opposite side of the elect-
rical contact) fits snugly on the protruding portion on the mount head
unit as shown in the figure.
6
Turn the DEC motor module to change the orientation so that the
screw holes (larger holes with no thread) are aligned in tandem. Repla-
ce the three socket head cap screws in place and tighten the screws
securely with the 3mm Allen wrench.
