Operation
5.1
Alarm Signals
The warning device indicates an alarm status or sensor fault both visually and
acoustically. The respective "OVERFLOW ALARM" or "HIGH OIL LEVEL"
("SLUDGE ALARM") LEDs are illuminated until the system returns to a normal
status.
5.2
Resetting the Alarm Signal
Pressing the "ALARM RESET" button resets an alarm that occurred in the past
(flashing green LED).
If the alarm status is still active, pressing the "ALARM RESET" button resets the
acoustic alarm and the relevant relay. The sensor LEDs remain lit/continue to
flash.
If the DIP switch "Repeat alarm in 24 hours" is set to ON (see chapter 4.1), the
alarm is repeated after 24 hours.
