INSTALLATION OF ENCODERS AND ENCODER HOUSINGS –600E MOUNT

ENC600 (purchased separately)

Parts List:

Right Ascension (R.A.) Encoder housing (black anodized)

Declination (Dec.) Encoder housing (black anodized)

R.A. Axis Adapter (clear anodized - silver colored), labeled R.A.

Dec. Axis Adapter (clear anodized - silver colored), labeled Dec.

To install your encoders, first remove the telescope from your mount. Remove your declination counter weight(s) and declination

counterweight shaft.

Fitting Declination Encoder Housing

If the encoders were purchased with the 600E mount, it

is likely that the declination axis adapter and encoder

housing have already been installed. No further action

will be required, as this encoder will remain in place.

If the encoders were purchased separately, the silver-

colored Dec. axis adapter may be inside the black Dec.

axis encoder housing. If it is, remove it now.

Thread the dec. axis adapter into the end of your dec.

axis (from where you earlier removed the dec.

counterweight shaft). Final tightening should be done

with firm hand pressure. Normally the Dec. axis adapter

will not be removed.

If you look into the black encoder housing, you will see

the encoder itself mounted at the rear of the housing.

When this installation procedure is complete, the

encoder shaft will insert into the center hole of the Dec.

axis adapter. This allows the encoder to read the

motion of the declination shaft as the declination axis

moves.

Thread the Dec. encoder housing onto the Dec. axis

housing. You may need to wiggle the encoder housing

gently to engage the shaft of the encoder with the hole

in the center of the Dec. axis adapter. When the

threading is complete, tighten up with firm hand

pressure since normally this encoder housing will not

be removed.

The counterweight shaft may now be rethread into the

rear of the Dec. encoder housing.

Fitting Right Ascension Encoder

Housing

If the encoders were purchased with the 600E mount, it is likely that the right ascension axis adapter and encoder housing

have already been installed. Please continue to read these directions since you may need to remove and reinstall the

encoders if you use a polar alignment scope. Since the polar axis telescope and R.A. axis adapter thread into the same

location, you will need to switch back and forth between them as needed. If you use the JMI NGC MAX or Mini MAX Digital

Setting Circles, you can use the "polar align" mode in these units instead of a polar alignment scope.

If the encoders were purchased separately, the silver-colored R.A. axis adapter may be inside the R.A. axis

encoder housing. If it is, remove it now.
