MOTORIZE- ROLL OFF ROOF

Once I started using CCDAP4 for automating my imaging runs, it became quickly apparent for the need to automate the roof opening and closing . I used a modified electric hoist, gear motor to drive the the roof.

This system has performed so well over the years, I offer a motor kit package (modified motor + control box). For Details..............see link below.

MOTOR MODIFICATION WITH SPUR GEAR + BEARING BLOCK
I machined and added a custom bearing block for better strength and support of the spur gear drive shaft.

MOTOR MOUNTING-

I mounted the motor on a 1/4" thick x 12" x 18" steel plate.
SkyRoof Program Dashboard

The SkyRoof software handles my remote roof control. It interfaces wtih CCDAP and reads the weather from my SkyAlert , cloud sensor.
ADJUSTER BAR

Added a 1/2" x 1/2" steel bar with cap screws for fine adjustment of motor/ spur gear position.

COVER IN PLACE

Covered with matching indoor/outdoor carpeting.

RACK INSTALLED

Rack shown engaged with spur gear.

OLD CONTROL BOX & LIMIT SWITCHES

The control box houses a manual toggle switch (DPDT spring centered- replaces original motor control switch) for manual motor open and close. Also, inside are (2) DPDT 12vdc relays that are controlled via AMC-100 software.

On the outside is a 5 amp fuse with a 0-5 amp meter to monitor current load. Opening and closing pulls about 3.5 amps. I installed motor limit switches on full open and full close to prevent any possible roof over-runs.

The near limit switch is for "Roof Close Stop" and the far limit switch is for "Roof Open Stop." The roof is in a midway position, so the switch trip cams are not in view. Also, note the ~2 " offset between both switches to avert trip cams from activating switches from the wrong direction.

NEW CONTROL BOX

I re-design the control box to be housed in a standard PVC junction box and improved the component layout..

The main reason for this project was to cleanup the old wiring and provide a design that could be fabricated and tested.If anyone is interested in this type of system and wants to interface with SkyRoof, Foster Systems, or m1OASYS Remote PC Controllers, I can provide this control box + the modified motor.

INTERNAL WIRING

Two DPDT relays seen on the left, are used to automate roof opening and closing.

Interactive Astronomy- "SkyRoof" Remote Controller/ Relay Board

PC interface uses a direct USB connection to the controller/ relay board.

CUSTOM FIT COVER

Designed with quick hang-on hook/ hole & clip for easy access.

ROOF IN ACTION

Roof opening has (2) limit switch/ trip cam positions. The position shown is a partial opening when using the imaging scope only. This position still covers the desk/ computer, minimizing potential dew in that area. A full open position may be set to fully exposed my other scope for visual activity.
