18.7 LOCK ALARM – ixF=bAL
The digital input reports an external alarm conditions which causes the lock of the device. In this
case:
- alarm LED and digital output set as alarm (oAx=ALr) will be activated;
- all the compressor outputs (oA1, oA2) will be deactivated (delayed of 1 sec each from
the other);
- solenoid valve control output (oA3=dGt,d4d) will be deactivated;
- oA1=dGt,d4d and oA3=dGt,d4d will be deactivated at the same time;
- analogue output will be deactivated (0V or 0Hz);
- the display will show the relative error label “CA”;
- the buzzer will be activated (depending on the par. bEn);
- the error will be saved into the database.
Alarm reset is automatic and happens when:
- the root cause ends and the digital input is deactivated.
The regulation always re-starts after the safety delays are up (es. 2on, minimum time between
two consecutive compressor activations, and 2oF, minimum time between one compressor stop
and next start-up.
The buzzer can be muted by pressing any button.
18.8 SECURITY INPUT – ixF=oAx
The digital input is used to deactivate the oAx output. It can be used to deactivate both
compressor and ventilators. The following outputs will not be affected from digital input:
- oA3 = dGt, d4d
- oAx = ALR
Any digital input activation will lead to immediately deactivate the linked output. This condition
will be signaled on the display by the label “EAx” (x=1, 2, 3, n) and by the flashing of the relative
icon. As soon as the digital input deactivates, the regulation will restart depends on the par. Ar.
If Ar=MAn, the output will stay locked until a manual restart (done by keeping the DOWN button
pressed for 3 sec and if rSt=YES).
18.9 REVERSE ANALOGUE OUTPUT ACTION – ixF=rEv
The digital input is used to reverse the analogue output set as proportional repeater (oAn=PrP)
from direct to reverse action.
19. ALARMS
Any alarm is visualized on the display with a specific code as reference. In case of multiple
alarms are simultaneously present, these will be visualized in rotation. The buzzer activation,
due to a new alarm condition, can always be muted if tbA=YES.
In case of a new alarm condition:
Alarm code signaled on the display.
Alarm output activation (oA1…oA3) if set as ALr.
Buzzer activation (if present and enabled).
Alarm condition memorization in the internal alarm list.
