Operator Interface

The Auto and Stop keys are used to put the unit into the auto or stop modes. Key selection is indicated by being darkened (reverse video).

The Alarms button is to the right of the Stop key. The Alarms button appears only when alarm information is present. The alarm blinks to draw attention to the shutdown diagnostic condition. Blinking is defined as normal versus reverse video. Pressing on the Alarms button takes you to the corresponding screen.

Persistent keys, horizontal at the bottom of the display, are those keys that must be available for operation regardless of the screen currently being displayed. These keys are critical for machine operation. The Auto and Stop keys will be presented as radio buttons within the persistent key display area. The

selected key will be dark. The chiller will stop when the Stop key is touched, entering the stop sequence. Pressing the “Immediate Stop” button will cause the chiller to stop right away.

The AUTO and STOP, take precedence over the ENTER and CANCEL keys. (While a setting is being changed, AUTO and STOP keys are recognized even if ENTER or CANCEL has not been pressed. Selecting the Auto key will enable the chiller for active cooling ( if no diagnostic is present.)

Chiller Stop Prevention/Inhibit Feature

A new chiller “Stop prevention/ inhibit” feature allows a user to prevent an inadvertent chiller stop from the DynaView screen for those chillers which are solely controlled by the CH530.

How It Works

This new feature will be activated after the service tech sets a variable shut down timer in TechView to be greater that 0 seconds and up to 20 seconds (i.e. 0 < Timer ± 20). Then, when the user presses the ‘STOP’ button on the DynaView display and initiates a chiller shutdown, a window will now appear that displays the “Unit Stop Information Screen” as shown below.

TechView service tool is utilized to enable this feature.
