9.2
Explanations about the automatic restart of the Chiller KSC215-L-…
The following power failure situations are considered:
1.
Main switch: On => Off => On
2.
Mains supply: ok => power failure => power returns
9.2.1
Main switch: On => Off => On
When switching the main switch off and on again, the operator’s display shows the a failure message called
„phase sequence“ (blinking) and at the electrical cabinet the green and the red indicator lamps are blinking to
indicate this failure. After a start-up time of around 20 sec., the chiller will restart automatically and the life bit
is on again. The red indicator lamp blinking goes off again and the green lamp continues blinking to indicate
that in the past in this situation a power failure / interruption occurred.
The chiller restarts automatically!!!!
In case the chiller does not restart automatically, the failure is still pending!
9.2.2
Mains supply: ok => power failure => power returns
Once power returns after a failure (phase sequence or phase failure), the screen also displays the error
message „phase sequence“ and the green indicator lamp at the electrical cabinet blinks to indicate that a
failure had occurred.
The chiller restarts automatically!!!!
Once the power supply has stabilized again, the chiller restarts automatically after a start-up time of around
20 secs, the red indicator lamp goes off, the life bit is on again, the green indicator lamp saying that a failure
was pending is still blinking and at the display the failure message „phase sequence“ remains visible.
In case the chiller does not restart automatically, the failure is still pending or another failure exists!
To set off the failure message at the operator’s display, press the „ACK-button“ at the display unit.
The blinking green or red indicator lamp at the electrical cabinet becomes permanent (green lamp) or goes off
(red lamp), if the „black RESET-button“ at the electrical cabinet is actuated.
