Section VIII - Power$ync IIOperation

Start-up

The Power$ync IIfour-line, forty-character display provides information in English, should a problem occur. If the operating requirements were properly noted when the machine was ordered, it will be completely ready to run once installed. All settings have been adjusted at the factory per the instructions on the order. If the operating requirements have changed since the machine was ordered, the control can be easily adjusted for new parameters.

NOTE

The voltage unbalance between phases should not exceed ±5%. If this unbalance is not corrected, the current draw may be excessive.

Once the wiring between the disconnect and the compressor is complete, the discharge piping has been connected to the air system and the water source for water-cooled units is connected and turned on, close the disconnect to provide power to the control. The power- on indicator will light on the control panel and the computer will run a short diagnostic program to confirm that all software and hardware are functioning properly. Should a software or hardware problem be identified, the computer will display the nature of the problem. If the problem is minor, the computer will allow the compressor to operate after an operator confirms knowledge of the problem. If the problem is major, the computer will prevent the compressor from operating in Power$ync IIMode until the problem has been corrected. In most cases, even with a major fault in the computer control system, the compressor can still be operated in Back-up Mode until repairs can be made. A complete description of these diagnostic message displays can be found under the Power-up Displays heading of this section.

The diagnostic program also checks the function of the LCD display screen. If the controller cannot properly communicate with the display, it will flash all the amber warning lights to draw attention to this fact. If there is a fault with the LCD display’s memory, then only the RED LED’s will flash.

After the diagnostic program has determined that all systems are functional, the computer will display a message prompting the operator to either press ENTER to move into the menu section or press START to begin compressor operation.

!WARNING

Under no circumstances, should any welding be done on the compressor package. Welding can damage the computerized controller.

Power-up Displays

This section will identify minor fault conditions, major fault condition that will prevent the compressor from running in any mode of operation and major fault conditions that will prevent the compressor from running in the Power$ync IIMode, but will allow Back-up Mode operation.

When power is turned on to the unit, the computer will run a short diagnostic program to confirm that the machine is ready to operate. If the diagnostic check finds a problem with the computer or sensors, a message will be displayed describing the nature of the problem.

There are two categories of problems that can be detected, those which would result in unsafe operating conditions (the computer is programmed to prevent the compressor from running if this type of problem is detected) and those which should be corrected as soon as possible, but will not result in an unsafe operating condition. The computer is programmed to allow the compressor to operate with minor problems that do not affect the safe operation of the compressor after an operator acknowledges the problem by pressing ENTER.

!WARNING

Always disconnect and follow lockout/tag-out procedures before attempting any repair or adjustment to any electrical component on this compressor. Failure to do so could result in serious injury or death.
