Screwdriver
Allen wrench to fasten motor in place
Assembly
First remove the flexible shaft. Bring the entire assembly to the horizontal
(illustration C).
Now place the motor in the guide opening of the mounting (illustration C).
Make sure the motor shaft points towards the mounting drive shaft. Push
the Allen screw (6) through the fastening strap on the motor and tighten it
loosely.
Then install the cog (5) on the motor drive shaft and the cog clutch on the
mounting drive shaft.
Important note.
The clutch must be open when manually moving the mounting to pre-
vent damage to the drive motor.
Align the cogs on the axles so that they precisely interlock. The grub
screws must face the flattened shaft side before being tightened.
The motor fastening screw can now be tightened. Please then check the
position of the cogs again. They must not be slanted or press hard against
one another.
Commissioning
Close the clutch by turning the upper manual cog clockwise a little. Motor
and mounting now form a single drive unit.
Important note.
Manual operation with the clutch closed is impossible.
Insert eight Mono type batteries in the battery box (3) and make sure when
doing so that their polarity is correct. Now take the manual control system
(2) and connect the motor cable (1) as in illustration B. The battery box (3)
cable can now be connected to the D.C. power socket of the manual
control system.
Operation
To ensure correct tracking the mounting must first be aligned to the
celestial pole (see Operating Instructions). To turn on, the right sliding
control is set to „N" (when in the northern hemisphere) or „S" in the
southern. Tracking then commences automatically. Use the directional
buttons to correct matters by turning clockwise or counter clockwise at the
speed given. 32x is suitable to centre an object in the viewfinder or
eyepiece. 2x is suitable for making fine corrections. 1x is for very fine
corrections, e.g. in astral photography.
Note
Instead of using batteries the control system can also be powered from
the mains using a standard mains power unit or from lead accumulator
batteries. Make sure the connecting plug has the correct polarity (check the
specifications) and that the power supply is a constant 6 V DC!
The stepper motor warms up when operated for a long time. This is
quite normal and does not indicate any malfunction.
