Section VIII - Power$ync IIOperation

Start-up Displays

Once the diagnostic program has determined that the compressor is ready to begin operation, the following display will prompt the user to start the machine:

STG 1 OUT TEMP______STG 2 IN TEMP______

2 STAGE VERSION 1.04

PRESS ENTER KEY TO SELECT MENU OR PRESS START BUTTON TO START COMPRESSOR

Each compressor is shipped from the factory with the start-up configuration that was noted on the order. If this configuration is satisfactory, press START to begin compressor operation. Should a change in the configuration be required, or should you desire to check that the proper configuration has been entered into the controller, press ENTER. At this menu, press the button sequence F1- DOWN-UP-ENTER to lock out all adjustment menus. With the control locked, all operational displays will be functional but access to adjustment menus will be stopped. When pressing this sequence of buttons, a message will appear warning that you have pressed the wrong button.

NOTICE

THE KEYBOARD IS SECURED AGAINST POSSIBLE UNINTENDED ALTERATIONS SEE MANUAL TO UNLOCK THIS FUNCTION

This is aimed at discouraging people from finding the combination to the lock by accident. Pressing the same sequence again will unlock the adjustment displays and menus. The purpose of this lockout feature is to prevent unauthorized personnel from making changes to any setting on the compressor.

The UP or DOWN arrow keys will access the auxiliary pressure sensor displays:

ADDITIONAL SENSORS

STG 1 OUT P______STG 2 OUT P______

FLUID PRESSURE______

UNITS: ______STG 2 OUT TEMP______

This display is of the pressure readings for STAGE 1 OUT, STAGE 2 OUT and the FLUID PRESSURE. These pressures provide verification of the normal operation of the compressor.

Operational Displays

When START is pressed, one of three displays should appear, depending on the mode of operation selected. If, however, the compressor has been manually stopped and an immediate restart is attempted, one of the following messages may appear:

WARNING COMPRESSOR IS STARTING

COMPRESSOR WILL START WHEN THE STAGE 2

DISCHARGE PRESSURE IS UNDER 10 PSI

STAGE 2 DISCHARGE PRES ________

To avoid starting against a load, the Power$ync IIcontroller monitors the pressure in the Stage 2 discharge pipe. It will not allow the compressor to start until the pressure has been relieved (down to 10 PSIG) through the blowdown valve. When the pressure reaches that level, the compressor will restart without further action.

A starting display confirms that the compressor is starting and has all valves open:

STG 1 OUT TEMP______STG 2 IN TEMP______

COMPRESSOR IS STARTING

HOURS______STG 2 OUT TEMP______

Power$ync IIchecks for the proper rotation of the compressor at start-up. If the compressor is rotating in the wrong direction, the controller will shut the machine down and display the following message:

NOTICE

COMPRESSOR HAS SHUT DOWN

**NOTICE** POSSIBLE REVERSE ROTATION

REFER TO YOUR SERVICE MANUAL

Power$ync IIchecks for reverse rotation by watching the pressure rise in the STAGE 2 discharge. It will shut the compressor down if the STAGE 2 discharge pressure does not reach 8 PSIG within fifteen seconds of the time that the start button is pushed. If this message is displayed, disconnect and lockout and tag-out the power supply to the compressor. Remove two of the three leads supplying power to the starter. Reverse their position and reinstall them. Restore power to the compressor and begin the start-up procedure again.
