POWER ON LIGHT

This indicates the control voltage and the line voltage are available for starting.

POWER

ON

The operator panel is divided into two areas. The bottom row of four buttons provides direct control over the starting, stopping, unloading and loading of the compressor. These are defined by the symbols printed on the buttons themselves, as shown here.

START

Pressing this button will start the compressor if the display shows “Ready To Start”. The compressor will start and load if there is sufficient demand for air.

STOP

Pressing this button will activate the unloaded stop sequence. If the compressor is running loaded, it will unload and continue to run unloaded for an adjustable 10 to 30 seconds and then stop. If the compressor is running unloaded, it will stop immediately.

UNLOAD

Pressing this button will cause the compressor to unload and remain unloaded. The display will indicate the machine is “Running Unloaded”, and “Mode: UNLOAD”.

LOAD

Pressing this button will cause the compressor to load if the compressor is running and if the “Discharge Pressure” is less than the “Online Pressure”. This also returns the machine to the operating mode that is specified by the “Mode of Operation” set point.

The other five buttons provide access to various operator-selectable functions and machine operating conditions. The purpose of each of these buttons is defined by the display screen and the particular function being performed at that time.

ARROWS

These up and down buttons have multiple functions relating to the right half of the display screen. When lists are presented, the buttons are used to move up or down through the items on the list. The small arrow(s) displayed in the upper right corner of the display screen indicate when you can move up (designated by arrow head pointing up) and/or down (designated by arrow head pointing down) through the list.

When the value of a specific machine operating parameter is highlighted on the display screen for the purpose of changing that value, the buttons are used to change the value itself.

DISPLAY BUTTONS

The functions of the three buttons below the display screen change and are defined by the words immediately above them in the bottom line of the screen. Each function, such as MAIN MENU, STATUS, SET, etc., is described in appropriate sections in this manual.
