4 - 15

Mode

There are three modes:

•

Auto - The valve’s on or off state is controlled by the GC.

•

Off

•

The mode can be set by the user.

Status icon

Green means that the valve is on, or active; gray means the
valve is off, or inactive.

4.3.2.3

The EPC screen

Label

The name of the EPC as set in MON2020.

Switch

•

Auto: The EPC is controlled by the GC.

•

Fixed On: The EPC is controlled manually, through user input.

•

Not used: The EPC is shut off.

Set Point

Indicates the target pressure.

Fixed PWM Output

The desired percentage of power to provide to the EPC.

Current PWM

Indicates the current percentage of power being provided to the EPC.
