Maintenance message
If the LED above the
Alarm
key lights up yellow, maintenance carried
out by a service technician is required. The interval operation is con-
tinued. The respective message is recorded on the SD card. The
alarm relay does not switch.
The service technician determines which maintenance work has to be
performed by using a computer at the USB interface and then per-
forms the maintenance work.
When this has been completed, he or she acknowledges the mainte-
nance message by pressing the
Alarm
key for 3 seconds. Now, he or
she presses the
Manual
key and the device returns to the interval op-
eration.
