Both active and non-active alarms can be
acknowledged. When a non-active alarm is
acknowledged, it can be reset, which immediately
removes it from the active alarms list.
When all non-active alarms have been acknowledged,
only active alarms will remain on the list.

Reset
Pressing this button allows a specific non-active alarm
to remain on the active alarms list.

Pressing this button saves the changes made to the
active alarms list. Any changes that are made without
saving will be lost.
Reset PLC
This button, located in the upper right portion of the
screen, resets the active alarms in the primary
microprocessor, so they could be further
acknowledged or reset on the touchscreen interface.
Only those alarms for which the alarm condition is

otherwise, the RESET PLC button will have no effect.
A list of all chiller alarms are found in the
Troubleshooting chapter.
