ID Name ID Name
01 Controller
interface
board
02 Logic fault #1 The base board is waiting
for the controller to complete
its internal test.
This alarm may appear from time
to time upon starting. Any
initialization delay can cause this
alarm to appear. If the alarm
appears too often or if it is
permanent, there is an internal
error. Check the current software
version or replace the controller.
03 Valve Drv. off
line
The internal device which
controls all the auxiliary
outputs has a problem and
is not communicating
correctly with the
microcontroller.
Replace the controller.
04 Output
mismatch
overcharge
This alarm is due to a
disparity between the
operating states detected by
the two computers. The
controller has asked the
base board to activate the
output for the drive or the
pump but the interface does
not identify a command or
an operating state where the
drive or pump must be
allowed.
Check whether the software
versions installed on the two
consoles are correct. If so, there
must be an internal fault.
05 EEPROM There is a fault in the
management/verification of
the internal EEPROM.
It is an internal fault. Replace the
controller. The platform can still
function but the controller will use
default values for the internal
parameters.
06 Wrong RAM
memory
The algorithm used to verify
the main memory is working
with erroneous data.
Try to break the contact. If the
alarm is still present, replace the
controller.
10 Flash check Incorrect software
downloaded or the Flash
memory is corrupted.
Check the installed software
version or replace the controller.
15 Analog input
There is a fault in the A/D
converter of the micro-
controller.
Replace the controller.
