Chapter 5 APPLICATION
Motor Power

This allows for the changing electricity consumption of the mount as the need arises. When electricity consumption is set to “3”, the mount
will easily accomplish tracking and Go-To slewing of your telescope and equipment up to 10kgs (22 lbs). The smaller the value is set, the
lower the electricity consumption is used, but it may cause a failure in tracking or Go-To slewing due to a drop of the motor torques.

If your telescope is not well-balanced or “Motor Power” is not set properly, the mount may not have torque enough to track or slew the
telescope. If this happens, the STAR BOOK TEN will sound the alarm and the motors will stop momentarily. Then, the mount will restart
the tracking and Go-To slewing automatically to reach the target.

Note:

*

The wattages are based on the loading weight of 10 kgs (22 lbs) approximately. The electricity consumption is affected by the size of

equipment mounted and the temperature.

*

Electricity consumption at the maximum loading weight of 16 kgs (35.2 lbs) would be about 0.6A to 2.5A (7.5 watts to 30 watts) at 12V.

In the “Mount Setting” menu, choose “Motor Power” with the or direction key and press the key (or the key) to call up the
dialog box.

Choose your desired value by number with
the or direction key. Press the
key to enter and leave the dialog box.

The setting is defaulted to “3”

About Failure of Tracking or Go-To Slewing

If a total weight of the equipment installed on the mount is no more than 10 kgs (22 lbs) (excluding counterweights) and well-balanced, the
default setting “3” would be sufficient enough to operate the mount stably. Chose the setting “4” if the loading weight exceeds 10 kgs (22
lbs), and choose the setting “2” or “1” if the loading weight is far less than 10 kgs (22 lbs) and you want to keep the electricity
consumption as low as possible.

An allowable payload of the mount is limited according to the size of your telescope regardless of its weight. Typically the larger the
diameter of the telescope, the smaller the payload the mount accepts.

Do not overly restrain the electricity consumption as it may result in failure of the motor controls.
