2.8 Self
diagnostic
A200E has a number of built-in self diagnostic features intended to improve the overall operating
safety.
Generally speaking, when a fault condition is detected, the instrument is driven to a safety condition
deenergizing alarm relays.
Display indications are provided to help in fault finding.
2.8.1 Configuration memory integrity check
Check is carried out at power on.
If the configuration memory is found defective, the power on sequence will not be completed, all
relays are driven to alarm condition (deenergized), the analog output is cleared and the serial line is
deactivated.
A forced reconfiguration to default is then performed and the primary display shows the following
message:
I N I T
Blinking
The transmitter stays in this condition as long as a key is pressed by operator to acknowledge the
situation.
The instrument must be reconfigured and recalibrated.
