UPC20 Wiring Requirements

In the United States, the UPC20 must be wired by an authorized electrician inaccordance with the National Electrical Code, ANSI/NFPA 70-1987, as well as all

local codes.

In the European community, the UPC20 unit must be wired by an authorized

electrician in accordance with all applicable European codes.

A readily accessible disconnect device shall be incorporated into the fixed wiring.

An insulated earthing conductor that is identical in size, insulation material and

thickness to be earthed and unearthed branch circuit supply conductors, except that

UPC20 Universal Power Controller Product Information 1

Product Information

The UPC20 Universal Power Controller is a dual 20 amp AC power and Motor

Controller designed for conduit installation. The UPC20 is housed in a compact metal

wall-mountable enclosure and can be configured for a wide variety of power and

motor control modes. Low voltage contact-closure or open collector inputs allow

control from simple wall panels and/or remote systems. A test switch with an LED

indicator for each relay provides for local control and status information.

All functions and capabilities of the UPC20 are listed on the circuit board inside the

enclosure. Figure 1 and Figure 2 show the high voltage wiring and control features.

Figure 3 lists the specifications.

Definitions

The following are definitions of terms used in this manual.

Momentary Power Relay contacts are closed only as long as a closure

from input to common is maintained.

Latching Power Relay contacts are toggled (from open to closed and

closed to open) each time a closure from input to common is momentarily

pulsed.

P1 Circuit Connections

P1 terminals 5 and 6 are connections for 115/230 VAC to power the circuit board

electronics. For 277 VAC high voltage wiring, you can use these terminals separately

with 115/230 VAC input or provide 12 VDC to the board from the low voltage

terminal block, P2.

K1 and K2 are the power and motor control relay connections to P1 terminals 1 and 2

and 3 and 4, respectively. Each relay is capable of switching the following loads:

Resistive Load rating; 20 A @ 115/230 VAC

Fluorescent Ballast rating; 6 A @ 277 VAC

Inductive Load rating; 1 HP @ 115 VAC, 2 HP at 230 VAC

Jumpers include one 22 gauge and one 14 gauge wired to supply board power at

115/230 VAC and to connect the common terminals of the relays. The jumpers are

cut as needed according to the wiring options selected.

High-Voltage Wiring Options

Single circuit connections 115/230 VAC

These connections are typical for most motor and screen control applications. See

Control Options Modes

Motor Control mode

Figure 8 and Figure 9 list options and connections for motor control. DIP switch

settings provide single-, two- or three-button remote control contact arrangements.This mode is typically used for screen and drape motor control.

In motor control mode, only one power relay (motor) can be energized at a time.

When switching from one direction to another, the first motor is automatically turned

off and a half-second delay is inserted before the other motor will turn on.

Caution

If motors of any kind are used,

do not set to a Power Control

mode. When a Power Control

mode is selected, both relays

can be on at the same time.

Motors can be severely

damaged if this happens.

The motor will automatically turn off when the time determined by the motor time

delay potentiometer, R8, expires. Delay time can range from 0.5 to 90 seconds. It is

typically set to allow direction limit switches to operate, or to reach the desired

position.
