The regulations for both fans are identical, therefore there is only one regulation ramp which
is brought to a single analogue output. The position needs to be set from the constructor
Menu by going to parameter HA07. If HA07=0 the signal is not enabled on any analogue
output. It is also possible to associate at the two steps of enablement two digital outuputs for
the fans by setting the positioning parameters HF01(for delivery) and HF02(for pickup).
6.5.4 Air quality sensor cycles
When during planning purposes the regulation probe is positioned on the the pickup channel
(set PG05=1) at a satisfactory ambient temperature, it is necessary to activate cyclically the
pickup fan in order to “sense” the ambient temperature (parameter PC05 to enable).
The cycle is composed of a wait time (PC06) during which the fan remains shut off as well as
a wait time for activation (PC07) during which the fans will turn on. The cycle always
begins with a period of pause; as soon as the fan is shut down from the regulation ambient
temperature (satisfactory ambient temperature), the cycle will terminate if during the
activation phase the regulation ramp of the ambient temperature exceeds the activation point
of the fan. With the parameter PC08 you can decide whether to activate only the pickup fan
(PC08=0) or both the pickup and outake fans (PC08=1) during air quality control sensoring.
Note 1. If the fan regulation is continuous (PF01=0) the air quality sensor cycle can never be
activated and is thus unusable. If the pickup fan is not present (PG09=0) this function cannot
be used.
Note 2. The fan activation time during the cycle (PC07) must be sufficiently long with
respect to the protection time during the startup of the two fans (PF05) so as to ensure that
both fans are able to turn on during the start up of the air quality sensoring phase (if
requested, see PC08).
6.5.5 Fan status
Below are the different operating modes in which each fan may find itself:
1. Disabled: the fan has not been configured for the implant. In this state in the user
interface you will see the symbol “ - ”.
2.
Off: the fan is off. In this state in the user interface you will see written “OFF”.
3. On: the fan is on. In this state in the user interface you will see written “ON”.
4.
Waiting for startup: the fan is about to startup, and is in a temporary queue. In this
state in the user interface you will see written (and flashing) “WON”.
5. Alarm: the fan is in alarm for thermal reasons or because of the alarm inverter. In this
state in the user interface you will see written “ALL”.
6. Manual: the fan is operating manually. In this state in the user interface you will see
written “MANU”.
