CAUTION

This is a PILOT DUTY device; it is not to be used for direct control of any type of motor. This device has been designed to control horsepower rated relays to run motors, and not run motors directly. These relays can have a maximum of 120 VAC coils.

When in doubt, check the current and voltage across the two wires this device will be switching. Some motor control boxes switch one side of the motor power at 240 VAC.

WARNING:

WHEN SERVICING, RISK OF ELECTRIC SHOCK - MORE THAN ONE DISCONNECT MAY BE REQUIRED TO DE-ENERGIZE THIS EQUIPMENT BEFORE SERVICING.

INSTALLATION

Installation of this product must comply with Local, State and National Codes.

This product is not suitable for installation in any wet, hazardous or explosive location.

Do not use knockouts on the top or sides of enclosure. Use only the knockouts on the bottom.

To get the full benefit of installing this controller it is advisable to have each dispenser on its own circuit breaker. In the case of mechanical dispensers it is advisable to have each hose on its own circuit breaker.

EMERGENCY SHUT OFF SWITCHES

When emergency shut off switches are required, the shut off switch should also control the AC power and the LINE terminal(s) on the Relay and Power Supply module. Then, if there is an emergency, the by-pass switches cannot over-ride the emergency shut off.

ELECTRONIC LINE LEAK DETECTORS

This controller is compatible with most Electronic Line Leak Detection systems. However, it must be installed so that the output from the controller is connected to the input of the Line Leak Detector. See the Line Leak Detector wiring diagrams.

240 VOLT CONTACTORS

When controlling contactors with 240 volt coils it is necessary to install an additional relay with a 120 volt coil to control the contactor, then use the relay contacts to control the contactor. See the 240 volt wiring diagrams.

WIRING DIAGRAMS

Wiring diagrams are furnished only as a guide to the installation of this product. When connecting to other manufacturers equipment or devices, that manufacturer's installation and operation instructions should also be consulted.

This controller was originally designed for service station use, but there can be many other uses, using different equipment and wiring variations.

It would be impossible to include wiring diagrams for all installation variations of this product; included are several typical service station wiring diagrams.

STAGE II, Vapor recovery

Located above U3 on the RPS module is a 8-pin socket that diodes can be inserted into to make submersible pumps or vacuum pumps operate at the desired time for vapor recovery systems. This socket is numbered 1 - 8 from left to right and controls outputs 1 - 8.

Page 2

BASIC OPERATION

When dispensers are used to control submersible pumps and no method of isolation is used in the submersible control wiring, hazardous feedback can occur in other dispensers that may not be in use. Relays are usually installed to correct this problem. This controller has been designed to eliminate relays and the large amount of interwiring that is necessary to wire them.

INPUT & SELECTOR MODULE

Each module can accept up to 8 submersible control wires. The upper terminal strip is connected to the dispenser submersible control wiring and its respective Neutral or common connection is directly below it on the lower terminal strip. Do not connect any INPUT & SELECTOR neutrals to the neutral on the RPS Module.

If Switched Neutral circuit breakers are used the dispenser neutral and the input Neutral should come from same breaker. Multi-product dispensers will require jumper wires between the Neutral terminals, See wiring diagrams.

Input signals from solid state devices with floating voltages in the off state may cause unpredictable results at the outputs on the RPS module. However, a resistor is included in the input circuit to pull this voltage down to an acceptable level.

ACCEPTABLE INPUT VOLTAGES, with 10k pull down resistor -

OFF: 0 - 30 VAC

ON: 90 -120 VAC

Questionable 30 - 90 VAC

Input voltage that is not at "0" volts in the off state may cause the input LED (RED) to glow slightly.

RED LED's (8):

Each LED will indicate when voltage is present on its input terminal. These LED's operate independently of the rest of the controller.

YELLOW LED:

12 VDC from the power supply.

GREEN LED:

This is for testing purposes only and should not be on during normal operation. To test the input optical isolator, set the input to be tested to 9 on the selector switch and apply voltage to the input; the LED will light if the optical isolator and PC Board connections are good.

SELECTOR SWITCHES:

These switches are used to set each controlling input (Letters B - J) to an output (Numbers 1 - 8) on the RPS board. When setting these switches, do not set any input switch to turn on more than one output. There is one exception to this. More than one switch can be set on applications where it is necessary to turn on two submersible pumps at one time using only one input. Caution, if any input is set to turn on only one of these submersible pumps, both pumps will always turn on.

RELAY & POWER SUPPLY MODULE

Part No. 100-RPS-4 can control a maximum of 4 devices. Part No. 100-RPS-8 can control a maximum of 8 devices.

Each output is controlled by a single pole relay. Above each relay is a RED LED to indicate the relay control status.

WARNING: DUE TO SPECIAL COMPONENTS IN THIS CIRCUIT IT CAN SWITCH 120 VAC CIRCUITS ONLY. To use 240 Volt contactors see page 2, 240 VOLT CONTACTORS.

Each output is also controlled by a by-pass switch. These switches are used to set the controller to "AUTO" (AUTOMATIC), "OFF" or "ON" operation. "ON" should only be used in case of controller failure, or testing other devices that may be connected to the outputs.

DO NOT USE THESE SWITCHES TO MAKE LINE LEAK DETECTION DEVICES WORK PROPERLY.

YELLOW LED:

12 VDC from the power supply.

RED LED's (2):

The top LED indicates AC line voltage at terminal L1 (power supply voltage). The bottom LED indicates AC line voltage present on the Output Disable terminal. These LED's operate independently of the rest of the controller.

GREEN LED's (2):

The top LED is for future use. The bottom LED indicates RUN - STOP status from the Output Disable terminal or the Output Disable terminal by-pass jumper on J1. Both LED's must be on for the controller to operate.

OUTPUT DISABLE:

This is an optional feature, outputs are enabled when this terminal is supplied with 120 VAC from any other UL Recognized switch or device. When it is de-energized, it will then disable anything that is connected to the output terminals.

All EDC's are shipped with this feature enabled, if it is not used it must be disabled, move the jumper on J1 from pins 2 - 3 to 1 - 2 to disable this feature.

WARNING:

THE OUTPUT DISABLE TERMINAL WILL HAVE NO CONTROL IF THE BY-PASS SWITCHES ARE SET TO "ON" OR THE JUMPER ON J1 IS ON PINS 1 - 2.

SETUP INSTRUCTIONS

Complete Setup Chart and leave on site with controller for future reference.

1 - Define PRODUCT PUMPS using CHART 2.

2 - Assign each Input (Letters B - J) a number on CHART 1. using the Output No.'s from CHART 2.

3 - Using the Output Numbers from CHART 1, set the selector switches on each I & S board. (Left is "ON" - Right is "OFF")

4 - Set any unused selector switches to "OFF".(Right position)

5 - If the Output Disable Terminal is not used, move the jumper on J1 from pins 2 - 3 to 1 - 2.

6 - Set by-pass switches to AUTO, set any unused switches to OFF.

WARNING:

THE OUTPUT DISABLE TERMINAL WILL HAVE NO CONTROL IF THE BY-PASS SWITCHES ARE SET TO "ON" OR THE JUMPER ON J1 IS ON PINS 1 - 2.
