MicroController Control System
Testing And Adjusting
5) INCORRECTSTART
A running request is present on key startup.
Possible causes:
a) Operator error.
b) Request microswitch stuck.
6) I HIGH AT STAND
Test carried out in standby, checks that the current
is nil. If this is not verified, an alarm is signalled.
This alarm shuts down the machine.
Possible causes:
a) Current sensor broken and logic failure.
First replace the logic, and if the defect persists,
replace the power unit.
7) I=0 EVER
Test carried out in running.
Checks that the current during running is greater
than a minimum value. If not, an alarm is signalled
and the machine is shut down. Possible causes:
a) The current sensor is faulty. Replace the power
unit.
8) EEPROM PAR.KO
Fault in the area of memory in which the
adjustment parameters are stored. This alarm
inhibits machine operation.
If the defect persists when the key is switched off
and on again, replace the logic.
If the alarm disappears, remember that the
parameters stored perviously have been cancelled,
and replaced by the default values.
9) EEPROM CONF.KO
Fault in the area of memory in which the special
chopper configuration data is stored. If the defect
persists when the key is switched off and on again,
replace the logic. Otherwise, keep in mind that the
chopper configuration has been reset to the default
values(regeneration voltage, etc.); thus it must be
re-programmed. Consult the console manual.
10) EEPROM DATA KO
The data in the area of memory that handles the
hour-meter is incorrect. This alarm does not shut
down the machine. If the alarm disappears when
the machine is switched off and on again, keep in
mine that the hour-meter data has been reset to
zero.
11) EEPROM OFF LINE
Fault in the non-volatile memory that contains
data relative to the area for the hour-meter, the
alarms stored and the programming parameters.
If the alarm persists when the key is switched off
and on again, replace the logic.
12) CHOP. NO CONF.
An alarm similar to no.9, except that here, enen
though the data is correct, it does not correspond
to a hardware configuration recognised by the H2.
The considerations are the same as for alarm 9
“EEPROM CONF. KO”.
13) WATCH-DOG
The test is made in both running and standby.
It is a self-diagnosis test within the logic.
If an alarm should occur, replace the logic.
