Frequently Asked Questions - LVC-IV Draper

How do I wire the LVC-IV controller?

Connect the 24V DC power supply to the terminals marked 'POWER' and connect each motor to the corresponding channel output terminals (CH1-CH4). Use appropriate gauge wire for the load.

Can I use this controller with non-Draper motors?

The LVC-IV is designed specifically for Draper motorized shades and screens. Using it with other motors may damage the controller or the motor.

What is the maximum total load?

Each channel supports up to 2A at 24V DC, giving a maximum total load of 8A across all channels.

How do I reset the controller?

To reset, disconnect the power supply for 10 seconds and reconnect. The controller will power up in default mode.

Does the controller have a wireless option?

No, the LVC-IV is a wired controller only. For wireless control, consider Draper's RF or Wi-Fi interface modules.

How do I mount the controller?

Use the included mounting bracket to attach the controller to a wall or other flat surface. Secure with screws (provided).

What does the LED indicator mean?

A steady green LED indicates power on. Flashing LEDs on a channel indicate that the corresponding motor is active.

Can I control multiple shades simultaneously?

Yes, each channel operates independently. You can activate multiple channels at once to control multiple shades.

Is the controller compatible with low-voltage wiring?

Yes, the controller operates on 24V DC low voltage. Use standard low-voltage wiring (e.g., 18 AWG) for connections.

What should I do if a channel is not responding?

Check the wiring connections and ensure the motor is functioning. Test the channel with a known working motor. If still not working, the controller may need service.

USER MANUAL LVC-IV Draper

Please Note

-Don't let the RF receiver touch metal objects; this could affect the maximum distance the transmitter can be from the RF receiver.
-Disconnect the power supply before installing the RF receiver.
-Avoid electrostatic interference: Static electricity will damage the electronic components.
-Make sure there is more than 5 feet (1.52 meters) between the RF receiver and ground.
-Make sure there is more than 1 foot (30.5cm) between the RF receiver and ceiling.
-Make sure there is more than 1 foot (30.5cm) between the RF receiver and transmitter.
-If using more than one receiver, make sure they are separated by more than 8" (20cm).

If you encounter any difficulties installing or servicing your LVC-IV, call your dealer or contact Draper, Inc.

Radio Frequency (RF) Remote Control

The LVC-IV comes with built-in Radio Frequency Remote control capability (optional handheld transmitter NOT included).

To "Learn" a remote

1. Press receiver button on LVC-IV (see Fig. 2A).
2. Signal light will flash slowly.
3. Press transmitter's Up button within 10 seconds (see Fig. 2B).
4. Signal light flashes three times quickly.

To "Un-Learn" a remote

1. Press receiver button on LVC-IV (see Fig. 2A).
2. Signal light will flash slowly.
3. Press transmitter's Down button within 10 seconds (see Fig. 2C).
4. Signal light flashes three times quickly.

To "Un-Learn" all remotes

Figure 2

1. Press receiver button on LVC-IV until signal light flashes quickly, then release.
2. Press receiver button once while signal light is flashing.
3. Signal light will stop flashing.

Please Note: Operating range is 250ft (76 meters) open distance. RF Signal will degrade significantly with each wall it is required to penetrate. If you are experiencing issues with RF signal strength, the RF antenna can be threaded out one of the knockouts for better reception.

InfraRed (IR) Remote Control

1. Plug Optional IR Eye into mini plug input provided on LVC-IV (see Figs. 1 and 3).
2. IR Remote Control transmitter does not need to be "learned" by the LVC-IV. Simply point and operate.
3. Maximum IR Eye cable length is 42" (106 cm).

Please Note: IR Transmitter Range is 26ft. (7.9 metera).

DC Low Voltage Trigger

The LVC-IV comes with built-in connection for sending a DC trigger (4-28 VDC) from the projector to the projection screen.

1. Connect remote trigger voltage from projector to the low voltage trigger cable.
2. Plug the mini-jack plug of the low voltage trigger cable to the LVC-IV (Figure 1 & 4).
3. When projector is 'ON' the low voltage output of the projector will cause LVC-IV to deploy projection screen. When projector 'OFF' the low voltage is removed from LVC-IV and projection screen will retract into case.
