SIGNALING
– low pressure alarm at
elevated compressed air demand. The
display flashes orange.
PRESSURE - current pressure in the
system
The display automatically disappears once
the air pressure is above 3 bar.

compressed air system as needed and
without restriction.
Medium priority alarm conditions
•
Air pump malfunction
The message on the display (FAULT) and
indicator P2-ALARM (17) indicate that the air
pump is not running (a motor circuit breaker
(Q1
– Q9) is tripped due to current overload).
The display flashes red.
The other air pumps are working normally.
The screen disappears once the malfunction
is remedied and the motor circuit breaker is
manually placed back in the “ON” position.
The display for normal operation is shown.
The compressor only supplies compressed
air to the central line through the functional
air pumps.
All alarms are automatically recorded on an
SD card.
Alarm signals have priority over maintenance interval signals. As such, the light
will indicate an alarm from any of the air pumps.
All error signals are connected to controller output K3:Q3.2 and to terminals
X1:44 and X1:45 (in the control panel) as NON VOLT ALARM SIGNAL.
Data collection
Data is recorded on a micro SD card in a slot in the base
module. Malfunction and operating event data is
recorded on this card. Information is saved in “.csv”
formatted files. The system sequentially saves data into
50 files, each of which may have up to 20,000 lines.
To copy data from the SD card, manually remove the
card and load the data using Excel onto a PC or
remotely via the Ethernet network.
