States of emergency
(
alarm
)
The alarm from the inputs of the pressure controls
(pressostats)
DI0
up to
DI3
(additional signal-
ling by means of
H3
lamp):
Appearance of any of the alarms
ALPR1
–
ALPR4
activates the alarm lamp
H3
lighting pulsati-
vely, as well as switches on the acoustic signal (buzzer).
To confirm the alarm, press the
S2
(
STOP
) button. The occurrence of the alarm blocks the sys-
tem function
– until the alarm stops.
After the alarm reason is fixed
, press the
S2
(
STOP
) button
one more time
– this will delete the
H3
lamp.
In case of the adjusted parameter {
Cons. STOP = ON
}
the alarm
can
be confirmed
, and
subse-
quently deleted by means of the input
DI5
.
CAUTION
: The activated alarms
ALPR1
–
ALPR4
can be blocked by a parameter {
ALPR akt.
=
NIE
} on the Screen
MODES 4/6
.
The alarm from the input
(
that confirms the function of the motor disconnector
)
–
addi-
tional signalling by means of H1
):
All the time, the system controls the status of the disconnector of the fan motor. In case of the
signal of contact opening
– occurs an immediate
interruption of the system
function. The alarm
is signalised by the
H1
lamp lighting in blinking.
Whereas, when the alarm
appears
on the con-
troller display (on the
Master Screen
)
– a message
ALRS
emerges.
The
ALRS
alarm activates the
H3
alarm lamp lighting pulsatively. The alarm has to be confir-
med with the button
S2
(
STOP
). The alarm causes blockage of the system, until the alarm dis-
appears.
After the alarm reason has vanished,
press the
S2
(
STOP
) one more time
– this will
switch off the lamp
H3
.
In case of the adjusted
parameter
CONS. STOP
=
ON
the alarm can be confirmed,
and subse
-
quently it can be deleted with input
DI5
.
The alarm indicating the lack of supply of the electro-valves
(
additional signalling with
H3
).
The signal controlling the correctness of power supply
24VAC
is for operating the electromag-
netic valves.
The controller indicates on display
the
lack
of
supply
in
case when for example the
fuse is burned out.
