Zero G Pro: Installation Guide

Screen Overview #

Important: Due to structural reasons, the screen position is offset from the center of the casing:

• 4¼” (105mm) for small cassette screens

• 3⅛” (80mm) for large cassette screens, to the right

• Account for this offset when determining mounting hole locations and maintain 0.4 meters clearance on the power cord side for future service

Suspended Ceiling Installation Method #

Step 1: Measure and Mark #

1. Measure the distance for the four hanging screw holes on the screen (refer to diagram below)

2. Calculate the screen’s installation position and mark the four hole locations for threaded rods

3. Cut threaded rods to required length and secure them in place

Step 2: Lift and Adjust #

1. Use lifting equipment to raise the screen to installation position

2. Adjust the installation bracket horizontally to ensure threaded rods align with and pass through bracket holes

Step 3: Fasten and Level #

1. Fasten the nuts onto the threaded rods

2. Adjust nut height and use a level to ensure screen is perfectly horizontal

3. Double-check all connections are secure

Precautions:

• Screen fabric is offset to the right from casing – account for this when calculating installation position

• For closed suspended ceiling installations, reserve about 15¾” (400mm) of space on the power supply side for maintenance

• Pay attention to screen material’s projection surface orientation to avoid installing backward

Setting Limits #

Upper Limit Setting #

1. Briefly tap the programming button on the back of remote control until LED light in programming hole illuminates

2. Move screen to desired upper limit position

3. Press “Stop” button

4. Briefly press program button and verify LED light has turned off

Lower Limit Setting (Drop Height) #

1. Briefly tap the programming button on the back of remote control until LED light illuminates

2. Move screen to desired lower limit position

3. Press “Stop” button

4. Briefly press program button and verify LED light has turned off

Warning: To guarantee the screen’s precise positioning and safety, DO NOT use the motor adjustment key to adjust limits.

Critical Safety Information:

• Exercise extreme caution when setting screen’s retraction height

• Over-adjusting may cause bottom bar to become lodged in casing, potentially damaging screen or causing bottom bar to drop

• Careful consideration needed when setting deployment height

• Steel cable should not extend beyond 5 meters – exceeding this limit could reverse cable reel, hindering screen retraction

Changing Motor Direction #

1. Push and hold the Programming Button until the screen jogs once

Controlling the Screen #

Warning: An activation button has been added to safeguard the internal steel cable system. Before turning on power, ensure you completely remove the yellow adhesive tape from the screen. Failing to do so could damage internal steel cables and create safety risks.

Zero G Pro has 5 control methods:

• Manual control (cycle button)

• Wireless control

• Dry contact control

• RS485 or RS232 control

• 12-Volt Trigger

Manual Control #

• Manual control button is located on left side of enclosure near RJ45 connection

• Pressing button commands: extend → stop → retract → stop in sequence

RF Remote Control #

• Down button: Screen extends to set position

• Stop button: Screen pauses

• Up button: Screen retracts

Pairing/Unpairing (Remote pre-paired at factory) #

Method 1:

1. Press and hold cycle button for 3 seconds – screen will jog once, entering pairing mode

2. Within 10 seconds, press both up and stop buttons on remote simultaneously

3. Screen will jog again, indicating pairing is complete

4. Odd-numbered operations pair, even-numbered operations delete code

Method 2:

1. Disconnect screen’s power for 10 seconds, then reconnect

2. Within 10 seconds, press both up and stop buttons on remote simultaneously

3. Screen will jog slightly, indicating pairing is complete

Individual Pairing for One-to-One Control #

To ensure precise one-to-one control, each device must be paired individually:

• When pairing with single screen, ensure all other screens are completely powered off

• Power on and pair each screen one at a time

• This guarantees each control is uniquely mapped to specific screen

Important: Before re-pairing, existing pairing memory on each screen must be cleared.

Memory Reset Procedure #

1. Press and hold button on screen for 5 seconds

2. When indicator LED begins flashing rapidly, press button again

3. Memory will be cleared and device ready for re-pairing

Dry Contact, RS485/RS232 Control, 12V Trigger #

RS485/RS232 Port Settings #

• Data Bits: 8 bits

• Stop Bit: 1 bit

• Baud Rate: 2400

Hex Control Codes #

• Up: FFEEEEEEDD

• Stop: FFEEEEEECC

• Down: FFEEEEEEEE

• Address code: FFEEEEEEAA (for some central controls)

• Learn address code: FFXXXXXXAA (XXXXXX = hex characters other than E and 5)

Important RS232/RS485 Notes:

• If unable to control screen, try switching the two control wires

• Wiring loop resistance should be less than 20Ω

• Do not run wires parallel to strong interference sources

• For RS232: send data string twice in succession with 2400, n, 8, 1 settings

Parts in the Box #
