Pro Max User’s Manual

Rain Master Irrigation Systems

The Universal Adapter is equipped with a 35-conductor connection cable RMIS Part Number
32PC, which must be physically wired to each station of the generic controller.

Note:

If you have purchased model Pro Max-UA and you need to connect to a
Rain Master controller, the Universal Adapter box (PM-UDAPT) is not
required. Refer to section 2.0 for installation and operation.

In cases where the controller does not provide the required 24 Volts AC, a step-down
transformer is employed to convert standard 117 Volts AC or 220 Volts AC to 24 Volts AC.

3.1

Using the Pro Max-UA Universal Adapter with a Non Rain Master
Controller

The controller serves only two purposes when using the Universal Adapter.

First, it provides 24 Volts AC for the Pro Max receiver. Never allow more than the “normal” 24
Volts AC (up to 28 Volts AC maximum) to enter the Pro Max receiver through the wires
designated for 24 Volts AC. If the controller runs ON a voltage other than 24 Volts AC, use a
step-down transformer to convert the voltage to 24 Volts AC for input to the Pro Max receiver.
Transformers that convert higher voltages to 24 Volts AC are available from Rain Master.

Secondly, the controller serves as a point of connection for the field wires and the Pro Max
receiver’s output. Usually the point of connection is the terminal strip or a quick disconnect
within the controller or pedestal. Rain Master offers several types of connector cables for wiring
to the controller. The RMIS Part Number 32PC or RMIS Part Number 24PC Permanent
Connector Cable, which is intended to be permanently connected to the controller. The other is
the RMIS Part Number 32TC Temporary Connector using alligator clips.

3.2

Installing the Pro Max-UA System

To install a Permanent Connector, follow the instructions below. Prior to installation, please
observe the following precautions:

CAREFUL CAUTION

DANGER

WARNING:

STOP – PLEASE READ ALL INSTRUCTIONS AND
THE FOLLOWING WARNING MESSAGES
BEFORE OPERATING THIS EQUIPMENT.

Always use with the approved Rain Master cable connector assemblies (RMIS Part Number
24PC, RMIS Part Number 32PC, RMIS Part Number 32TC, RMIS Part Number 32EX) Use of
any other connector will void the warranty and may damage the Pro Max remote control system.

NEVER allow more than the “normal” 24 Volts AC to enter the Universal Adapter on
any of its wires. If there is any question about a connection voltage, check the voltages
with a voltmeter.

NEVER operate the Pro Max transmitter without the CORRECT antenna properly
installed.
