Cause(s)
Action
1
Yellow light illuminates continu-
ously for periods longer than 45
seconds in duration
Engine exhaust backpressure is
increasing and the DPF should be
scheduled for service within the
next 72 hours.
Purifilter systems - download BPM histogram
and parameter files and confirm reported
Yellow Alarm
Confirm duty cycle is acceptable for pas-
sive regeneration.
Remove DPF and clean
Perform all service items defined in the
Maintenance section under this service
Purifilter Plus systems - perform on-board
regeneration.
2 Red light illuminates continu-
ously for periods longer than 45
seconds in duration OR red
light stays illuminated at all
times.
Engine exhaust backpressure is at
a level where the DPF should be
cleaned within the next 24 hours.
Purifilter systems - download BPM histogram
and parameter files and confirm reported
Red Alarm
Confirm duty cycle is acceptable for pas-
sive regeneration
Remove DPF and clean
Perform all service items defined in the

If red light remains illuminated, contact
your ECS distributor to reset the red light
Purifilter Plus systems - perform on-board

Refer to Purifilter Plus manual if problem is
apparent.

Pink system error light flashes
continuously
Backpressure Sensor problem
* The logged parameter data and
user interface will show “-3276.8” in
the pressure column when there is
an abnormal pressure condition.
Check the backpressure sensor line for any
breaks or leaks . Check the tubing between the
water trap and exhaust pipe for any blockage
and clear with compressed air blowing toward
the exhaust pipe. Service the condensation
trap and condensation trap filter.
Thermocouple connection problem
* The logged parameter data will
show “SAT” in the temperature
column and user interface when
the thermocouple is disconnected
Check thermocouple connections. Check
thermocouple sensor. Make sure the thermo-
couple polarity is correct. Refer to installation
instructions.
High backpressure Error. Back-
pressure greater than 500 mbar.
This will latch the system error
light.
Follow the actions required in item 2 above.
Contact your ECS distributor to reset the
system error light.
Internal problem with the BPM
Contact your ECS distributor.
4
All lights on the remote driver
display are on continuously
Power supply voltage has been
out of the normal operating range.
The BPM will operate with a sup-
ply voltage between 9V and 30V.
Disconnect power to the BPM for 20 seconds
and then reconnect power. This can be done
by removing the fuse or the power connec-
tor, whichever is more convenient.
