DEFAULTS :
Name
Automatic
reset
Causes Effects Actions
Maintenance number of
cycles exceeded
YES
Manufacturer Counter number of
declogging cycles above the setpoint
« number of cycles »
- none on the running
- achieve maintenance
and reset manufacturer
counter
High alarm default
analog input
YES
Value corresponding to the value of the 4-
20mA signal is above the high threshold
- none on the running
---
Low alarm fault analog
input
YES
Value corresponding to the value of the 4-
20mA signal is under the low threshold
- none on the running
---
Analog input fault
YES
Signal 4-20mA error (<3mA)
- none on the running - check connections
between sensor and
sequencer
-check that the sensor
is correctly running
CDM communication
fault
YES
Problem of communication with CDM dust
sensor
- none on the running
- check connections
between sequencer and
CDM sensor
CDM : rejects alert
YES
Dust rejection is higher than the alert
threshold which is adjusted in page
« parameters CDM0 »(see CDM brochure)
- none on the running
- check the integrity of
filters
CDM : rejects alarm
YES
Dust rejection is higher than the alarm
threshold which is adjusted in page
« parameters CDM0 »(see CDM brochure)
- none on the running
- check the integrity of
filters
CDM : Alarm
Configuration
YES
Alert and/or Alarm threshold is out of the
measure range
- none on the running - decrease n1 and/or
n2
- reference measure
too high
Absence A/C
YES
The A/C presence input = 0
- no declogging
-check the good
working of the system
linked to the A/C input
High dP alarm
YES
Filter is clogged :
Load loss too high
- none on the running
- replace the filter
Low dP alarm
YES
Load loss of the filter is too low
- none on the running
- check the presence,
the correct fixing and
the state of the filter
Electrical fault
YES
At least one fault « electrical SVx fault »
(see here under)
(see here under) (see here under)
Electrical SVx fault
YES
No electrical consumption when the SV x
is activated
- no declogging on the SV x
- check the connection
and the correct running
of the SV
- check the fuse on the
sequencer electronic
boards
Short-circuit SV
electrical fault
YES
No SV is activated and the system notes
an electrical consumption on at least one
SV output
- one SV may be alaways
supplied
- replace the electronic
board
Link card SV n°X
YES
Problem of communication between
master electronic card and the card SV
n°X
- unefficient declogging
- check the connection
between master card
and card SV n°X
