Installation

The installation process involves panel cutout, mounting the controller, and connecting wiring. Refer to specific diagrams for PM3 and PM6 dimensions and recommended panel spacing.

General Steps:

1. Prepare the panel cutout according to the dimensions for the PM3 or PM6 model.
2. Remove terminal connectors and mounting collar.
3. Insert the controller into the panel cutout from the front.
4. Orient and slide the mounting collar and bracket over the controller.
5. Secure the mounting bracket with screws, ensuring the device is flush to the panel.
6. Reinstall the terminal connectors.

Wiring: Use National Electric (NEC) or other country-specific wiring and safety practices. Ensure proper wire size and torque ratings.

• Universal Process
• Mechanical Relay (Form C and Form A)
• NO-ARC Relay (Form A)
• Open Collector

Menu Navigation and Operation

The controller is operated using the front panel keys: Infinity Key, Advance Key, Up/Down Arrow Keys, and Function Key (FN).

Key Functions:

• Infinity Key: Clears alarms, silences alarms, backs up one level, or returns to the Operations Menu.
• Advance Key: Scrolls through menu prompts and advances through parameter prompts.
• Up/Down Arrow Keys: Adjusts set points, increments/decrements settings, or changes parameter selections.
• Function Key (FN): Toggles between Manual and Auto control modes.

The controller features an Operations Menu for real-time adjustments and an Set Up Menu for configuration and parameter settings.
