Parameter Val
Status
Configuration
ok
The configuration of the digital input is ok.
ko
The configuration of the digital input is wrong, this happen when a new control panel is mounted
on an old card with digital input configured. To solve the problem reconfigure in menu factory
EXTDI.
Communication
ok
The communication between the machine cards and the remote control panel works properly
ko
Problem with the communication among cards and remote panel:
1) check electrical connections between electric panel and remote panel (see wiring
diagram);
2) if the problem is not solved, check electrical connections between the cards (see wiring
diagram);
3) if the problem is not solved, check the dipswitch position in both cards, only 1 unit: X540
only 1=on ; X531 only 2= on;
4) if the problem is not solved, replace the electronic cards.
Te (external)
ok
The external air temperature sensor works properly.
ko
Problem with the external air temperature sensor:
1) check electrical connections of the temperature probe (see wiring diagram);
2) if the problem is not solved, replace the temperature probe;
3) if the problem is not solved, replace the electronic card.
Tr (return)
ok
The return air temperature sensor works properly.
ko
Problem with the return air temperature sensor:
1) check electrical connections of the temperature probe (see wiring diagram);
2) if the problem is not solved, replace the temperature probe;
3) if the problem is not solved, replace the electronic card.
Tx (expelled)
ok
The exhaust air temperature sensor works properly.
ko
Problem with the expelled air temperature sensor:
1) check electrical connections of the temperature probe (see wiring diagram);
2) if the problem is not solved, replace the temperature probe;
3) if the problem is not solved, replace the electronic card.
Ti (input)
ok
The input air temperature sensor works properly.
ko
Problem with the input air temperature sensor:
1) check electrical connections of the temperature probe (see wiring diagram);
2) if the problem is not solved, replace the temperature probe;
3) if the problem is not solved, replace the electronic card.
Tw (water)
It is present only if the air after-treatment control is equipped with a water-powered battery (Factory
menu).
ok
The water-powered battery temperature sensor works properly.
ko
Problem with the water-powered battery temperature sensor:
1) check electrical connections of the temperature probe (see wiring diagram);
2) if the problem is not solved, replace the temperature probe;
3) if the problem is not solved, replace the electronic card.
Tw (water) low
It is present only if the air after-treatment control is equipped with a water-powered battery (Factory
menu).
ok
The temperature of the water from the battery is higher than a safety threshold, there is no risk of
water freezing in the battery.
ko
Risk of liquid freezing in the water-powered battery.
Filters
It is present only if the filter status alarm with differential manostat is configured or is based on the ma-
chine operation hours (Factory menu).
ok
Clean filters.
ko
Clogged filters: replace filters. If the filters alarm is based on the machine operation hours, you
must reset the Filter Hours parameter (Installer menu).
Fans
It is present only if the fan status alarm is configured with differential manostats, with tachometric signal
of fans or with fan Digital Output (Factory menu).
