LOW AND HIGH PRESSURE ALARM DUE TO PROBES 1 AND 2
If the reading in probe 1 reaches the value set for parameter A03 , the message ALL (Low
pressure) is displayed on screen, the alarm relay (if available) is activated and the compressors and
fans stop.
This alarm differential is established in parameter
A04.
If the reading in probe 1 reaches the value set for parameter A05 , the message ALH (High
pressure) is displayed on screen,the alarm relay (if available) is activated and the compressors and
fans stop.
This alarm differential is established in parameter
A06 .
When the readings return to their normal values, the alarm relay deactivates but the
R
indicator remains on until
the
Q
key is pressed.
PROTECTION ALARMS
If one of the thermal protections goes off (digital inputs I1 to I5 , according to the configuration),
the message At1 ... is displayed on screen At5 , the associated element (compressor or fan) stops
and the alarm relay activates (if available).
Once the protection is reset, the installation returns to its standard operation, but the alarm relay remains activated
until the
Q
key is pressed.
SEVERE EXTERNAL ALARM
When the digital input configured as a severe external alarm ( I07 or I08=4 ) is activated, the
screen displays the message AES , the compressors and fans stop and the alarm relay activates.
Once the cause that triggered the alarm disappears, the installation returns to its standard
operation, but the
R
indicator remains activated until the
Q
key is pressed.
PROBE 1, 2 or 3 ERROR
If an error occurs in probes 1, 2 or 3 (disconnection, cross-over or probe out of range), the
screen displays the messages
E1 , E2 or E3 respectively, the alarm relay activates and the
compressors and fans go on to operate according to parameters A01 and A02 .
Once the cause that triggered the alarm disappears, the installation returns to its standard operation, but the
R
indicator remains activated until the
Q
key is pressed.
DEPROGRAMMED CLOCK ALARM
If the unit remains without electrical supply for a period longer than 6 hours, or upon its first start-
up, the screen displays the message
Ar , indicating that the internal clock is deprogrammed. The
unit will continue its standard operation, but if the energy save mode has been activated, it will
not start. In order to set the date and time again, adjust parameters
r01 to r05 . Activates the alarm relay.
PUMP DOWN ALARM STOPPED DUE TO TIME
If, during pump down, the maximum interval configured in E09 passes before the stop value
specified by E08 is reached, the last stage will stop and the message PdA will be displayed. Does
not activate the alarm relay.
