INSTALLATION INSTRUCTIONS

Model 2031, 3021, and 3028 2 Channel Receivers

WARNING:

∙Disconnect power before any installation or repair.

∙Wear safety glasses.

Congratulations! You have purchased a MULTI-CODE RECEIVER, which we believe to be the finest product of its kind on the market. If you take a moment to read the enclosed instructions, we think that you will find installation of your receiver to be quite an easy matter, and will assure reliable operation.

INSTALLATION

Your Receiver may be mounted in the operator head, if space permits, or remotely, if this becomes necessary. Note that all wires should be routed through the strain relief fitting or rubber grommet of the cabinet, except for the antenna lead.

Begin your installation by correctly wiring the receiver to the devices you will be using. WE URGE YOU TO BECOME

FAMILIAR WITH THE INSTRUCTIONS THAT THE MANUFACTURER OF YOUR EQUIPMENT HAS PROVIDED, SINCE, IN MANY CASES, THESE INSTRUCTIONS WILL DETERMINE THE WAY IN WHICH THE RECEIVER WILL BE INSTALLED.

Note that on the top half of your cabinet you will find a terminal designation schematic. This schematic is reproduced below for your reference (figure 1)

24 VAC

24 VAC

The two positions marked 24 VAC are used to attach your power supply. If you find that your operator supplies only 110 VAC, then contact LINEAR CORPORATION for the 1092-01 power supply, and we will provide an adapter for 110 to 24 Volt use.

The next three positions, above the 24 VAC positions, provide channel 1 selection. Selection of Channel 1 on the transmitter is made by setting the number 10 DIP switch to the open position. You must then choose to wire the first channel to a NORMALLY OPEN or NORMALLY CLOSED cir- cuit. To determine this, consult the manufacturer’s instruc- tions, as previously noted. Refer to your transmitter instructions for coding instructions. Now attach the second wire from your device to common.

Above the channel 1 positions you will see the positions which allow channel 2 to be wired. Channel two is wired in the same manner as channel one, with the exception of the transmitter code switch number 10 being placed in the closed or on position.

You will note that the two channels on the receiver may be used in any combination of NORMALLY OPEN or NORMALLY CLOSED devices.

At this point you should mount your receiver to its permanent installation, if you have not already done so. If you have a 3021 receiver be sure to tightly secure the strain relief fitting through which the wires are routed as this provides a degree of water resistance. Should you desire a watertight connection, use a single length of 16 to 22 gauge jacketed cable.

ANTENNA INSTALLATION

After you have mounted your receiver, test it with the enclosed antenna for range, noting the coverage that you get from all desired operating locations. If greater range or coverage pattern is necessary, you may choose the MULTI- CODE 1066 Coaxial Wiring Kit, which is available from LINEAR CORPORATION. Note that the external antenna
