Configuring the Warning Device using DIP Switches

Often, suspended particles (e. g. leftovers) can be found in the grease interceptor
and lumps of fat often form. These suspended particles and lumps of fat can
cause a false alarm for the fat level sensor. Therefore, it is possible to set two
possible monitoring states for the fat level sensor on the warning device via the
setting of DIP switch 1 (reaction time of the fat level sensor).
Switch setting ON – operating mode
The reaction time for detection of a fat layer is 24 hours (warning device in
■
normal mode, green LED "SYSTEM OK" lights up). Only after the fat level
sensor has constantly been in a fat layer for 24 hours is the alarm status
displayed via the LED "FAT LAYER ALARM" and, if applicable, an acoustic
alarm triggered and relay activated.
The reaction time for detection of water is 1 hour (warning device in alarm
■
mode, red LED "FAT LAYER ALARM" lights up). Only after the fat level sensor
has constantly been in water for 1 hour does the LED "FAT LAYER ALARM"
go out and the LED "SYSTEM OK" flashes.
Note!
Note that after switching on the warning device or after switching the DIP switch
from OFF to ON, the LED "SYSTEM OK" lights up for approximately 1 minute.
Only after this is the status of the sensor displayed as described above.
Switch setting OFF – service/test mode
After switching on the warning device or after switching the DIP switch from ON to
OFF, an alarm is detected immediately and the warning device displayed.
The DIP switches are located on the right of the device (see chapter 2.3).
