Sensor
)
– indicates filter condition and analog pressure
sensor failure, if any.
Clean
– filter is clean.
Dirty
– filter is dirty, the AC unit remains running and a message is displayed in the
alarm messages. After the filter has been replaced, the message in the alarm
messages must be cleared.
Clogged
– filter is very dirty, the AC unit has automatically shut down and a message
has been displayed in the alarm messages. After the filter has been replaced, the
message in the alarm messages must be acknowledged.
Sensor
– fault has occurred in the analog air pressure sensor, if configured.
Press
(Pa)
– current filter pressure, if monitored by the analog pressure sensor.
WrongOperatingHrs
(0)
– informs how long the AC unit has been operated with a dirty
filter in the state
Dirty
or
Clogged
.
AlarmsStates:
Filter
(
Dirty
/
Clogged
)
– this setting is only valid when monitoring filter clogging by a
pressure sensor with an output contact called a manostat, which indicates only two filter
states,
Clean
or
Dirty
(
Clogged
)
. It determines the behaviour of the AC unit when the
filter is no longer
Clean
.
Dirty
(200 Pa)
– specifies the pressure limit at which the filter clogging alarm is raised and
the AC unit continues to operate. It can only be set when monitoring filter clogging with a
0-10V analog output manometer.
Clogged
(300 Pa)
–
specifies the pressure limit at which the filter clogging alarm message
is displayed and the AC unit shuts down. It can only be set when monitoring filter clogging
with a 0-10V analog output manometer.
Delay
(60s)
– delay of the display of the alarm when the filter is no longer
Clean
.
Air quality
6.15
Air quality is a parameter that can affect the performance of the fans and the position of
the mixing (circulation) damper. Air quality can be monitored by sensors with digital outputs or
sensors with 0-10V analog outputs. This chapter covers air quality control by changing the amount
of fresh air supplied.
