Data congruence
EPROM error
RAM Error
EEROM Error
Totalizer Error
Optional Inputs/Outputs
Mass flow meter control
Data correspondence control. The computing
head checks, even during the delivery, both
EPROM and RAM data. In case an error
occurs, it finally stops the delivery.
Error Code: FECd
When nozzle hangs on, the computing head
checks the EPROM checksum. If something
is wrong, it doesn’t allow the delivery.
Error Code:
FEEP
When nozzle hangs on, the computing head
checks RAM. If something is wrong, it
doesn’t allow the delivery.
Error Code:
FErA
When nozzle hangs on, the computing head
checks the E²rom checksum. If something is
wrong, it doesn’t allow the delivery.
Error Code:
FEEE
The computing head checks the totalizer
presence. In case an error occurs, it finally
stops the delivery.
Error Code:
Feto
The computing head verifies the presence of
device dedicated to Self Service and other
applications
.
Error Code:
FEin
The computing head verifies the communi-
cation and/or of the reset procedure of the
mass flow meter; In case an error occurs it
finally stops the delivery.
Error Code:
FEMF
(also in the case of impulsive type mass flow)
