LC-I Control Switch Kit

LC-I Control Switch Kit This kit contains:
A microprocessor-based motor controller that can be mounted in a standard electrical box.
A white face plate.
A 24VAC 50VA Free-Air Transformer with a mounting plate (shown in picture) or a 24VAC 50VA Plug-In Wall Transformer.

The LC-I Control Switch can operate up to three motors (three Standard Motor Kits or Skylight Motor Kits or one Standard Motor Kit with up to two Motorized Locks). When opened or closed, each window moves in sequence to the same position. Independent control of a single window in a group wired to a common LC-I Control Switch is not possible.

The LC-I Control Switch should only be ordered when the lowest cost operation of up to three motors is desired. The LC-I Control Switch cannot be controlled from an RS Module, IR Receiver, or Rain Sensor and it cannot be integrated into a home automation system. If you need to control your windows or skylights with an RS Module, IR Receiver, Rain Sensor, or home automation system you should consider the LC-II Control Switch Kit instead.

To see how an LC-I Control Switch integrates with all of our other components to form a complete system for motorizing your casement, awning, and skylight windows, take a look our wiring diagram. It should give you a basic guideline for planning and creating your own motorized window and skylight system.

LC-I Control Switch Installation Instructions

You can download the Motor System Installation Instructions (1.26MB) to familiarize yourself with the LC-I Control Switch installation. The installation instructions are in Adobe PDF format and require Adobe's free Acrobat Reader. If you don't have Acrobat Reader you can download it from Adobe's website.

Step 1 - Gather Your Tools

#2 Philips head screwdriver
1/8" (3.0 mm) bladed screwdriver
1/10" (2.5 mm) bladed screwdriver
Electric drill motor
Drill bits (1/4" and 1/16")
An awl for marking mounting holes
Class II, low voltage wire for the motors, switches and transformers
An assortment of wire nuts

Step 2 - Run Electrical Wires

Use Class II stranded wire for all connections.
Use the table below to select the wire size for transformer and motor connections. Stranded wire is recommended for all transformer and motor connections.
Run the wires to the motors, switches, and transformers. Low voltage wires should be at least 12" away from high voltage (120 VAC or higher) wires to avoid any electrical interference.

Class II Wire Size	Total Distance Transformer To Farthest Window
18 AWG stranded	50 ft (15 m) maximum
14 AWG stranded	100 ft. (30 m) maximum
12 AWG stranded	150 ft. (45 m) maximum

Step 3- Install LC-I Control Switch Jumper Setting

Install jumper setting
Jumper Block

1. Verify the jumper setting on the LC-I Control Switch is correct for your application.
A - For windows with Motorized Locks.
B - For skylights.
C - For windows without Motorized Locks (no jumper installed).

Step 4 - Connect LC-I Control Switch

Connect LC-I Control Switch 1. The LC-I Control Switch can control up to three matching sized windows, OR three matching skylights, OR one window with up to two Motorized Locks.

2. Connect the LC-I Control Switch per the wiring diagram and the LC-I Connectors table below. There must be one transformer for each LC-I Control Switch.

3. Mount the LC-I Control Switch in a single gang electrical box.

LC-I Connectors

Symbol	Connection	Description
P	Power	Input from 24 VAC transformer. There must be one (1) transformer for each LC-I Control Switch.
MC	Motor Common	The common (ground) connection to all motors.
M1	Motor #1	The "hot" output connection to motor #1.
M2	Motor #2	The "hot" output connection to motor #2.
M3	Motor #3	The "hot" output connection to motor #3.

Step 5- Connect Transformer

Connect transformer 1. Install a Free-Air Transformer (pictured to the left) on a 4" x 4" junction box in a cool, dry location. The surrounding air temperature must not exceed 150° F (65° C). A Plug-In Wall Transformer can be plugged into any convenient wall socket.

2. Connect the transformer per the wiring diagram. There must be one transformer for each LC-I Control Switch.

Note: Installation must meet local and National Electrical Codes (N.E.C).

Note: Connecting the transformer directly to the motor can cause damage.

Step 6- Powering Up the System and Testing

Note: Before powering up the system all motors must be installed and correctly wired per Steps 1 through 6.

Because some windows open clockwise when the handcrank is turned and some open counter-clockwise it is important to determine which direction the skylight travels when power is applied.

Upon connecting power to the transformer wait 15 seconds without pushing any buttons. The system should automatically close all windows. Windows already closed should remain closed.
- If any of the units open, power should be disconnected and the motor wires to those units must be reversed either at the motor or at the switch.
- If any of the units fail to open or close, see the Troubleshooting Guide below.
If all windows closed correctly, press the "Reset" button on the front of the LC-I Control Switch. After a few seconds the LC-I Control Switch will automatically open each window/skylight to its full range of available travel. The LC-I Control Switch will then close each window/skylight. This procedure may take several minutes. Once the windows/skylights have closed again, the system is ready for normal operation.
After the system has been "Reset", momentarily pressing "Open" will open all units, one at a time, to the automatic vent position (approximately 80% of available travel). The units may be opened further for cleaning or servicing by holding the "Open" button after the vent position is reached. "Close" will completely close all units from any position. Note: Special open positions can be attained by pressing the button for the opposite direction of travel while the motor is running. This will halt the moving unit and move all other units to the same approximate position.
Each screen interlock must be checked when the unit is running. The motor should stop when the screen interlock is disconnected. Correct installation is the responsibility of the installer. Note: The system must be reset after each test.

Troubleshooting Guide

Symptom	Possible Solution
Unit does not operate, no sound from the motor.	1. Press the "Reset" button on the LC-I Control Switch to reinitialize the system. 2. Refer to the wiring diagram and check the connections. 3. Check for power at the transformer for 110-125 VAC input and 24 VAC output. 4. Check the screen interlock connection.
Unit makes a noise, but the window/skylight will not move or operates erratically.	1. Press the "Reset" button on the LC-I Control Switch to reinitialize the system. 2. Be sure the window is unlocked. 3. Be sure the window will operate freely without the motor attached. 4. Remove the motor cover and test. Be sure the cover screw length is #6 x 3/8 PH. 5. LC-I Control Switch may be incorrectly wired to the motor. Refer to the wiring diagram.
Unit runs slowly.	1. Due to gear reduction in different operators, the speed will vary. Skylights, due to very low gearing, are normally slower.
Unit does not close completely.	1. Press the "Reset" button on the LC-I Control Switch to reinitialize the system. 2. Be sure the window will operate freely without the motor attached. 3. Disconnect the power and refer to Step 6, Powering Up the System and Testing. 4. Check the jumper setting for the application. Refer to Step 3, Install LC-I Control Switch Jumper Setting.
Unit runs continuously in one direction when bench testing.	1. The motor must be connected to a window for correct operation. Note: Connecting the transformer directly to the motor can cause damage.
Unit closes when the "Open" button is pressed.	1. Motor leads are reversed. See Step 6, Power Up the System and Testing.
