If the checksum fails, a fault alarm is generated according to the user configura-
tion for the EEPROM corruption error (see "Alarm - Error configuration" section),
and the user will be asked to confirm or ignore a request of EEPROM reset.
If the request is ignored, the controller restarts operation, but alarm actions are
performed as configured by the user (see "Alarm - Error configuration" section).
Note that the device will be in Hold mode in any case.
If the reset action is confirmed, all the data stored in the EEPROM are erased
and the default values loaded. After that, the device must be completely
recalibrated.

Confirm the "Relays and LEDs test" option and the
instrument will ask for pressing a button to test a
relay or LED.
These are the keys used to toggle relays and LEDs
ON and OFF:
• the DIAG key toggles the alarm relay and the green LED
• the CAL DATA key toggles the red LED
• the up arrow key toggles relay 1 and corresponding LED
• the right arrow key toggles relay 2 and corresponding LED
• the SETUP key toggles relay 3 and corresponding LED
• the CAL key toggles relay 4 and corresponding LED
• the down arrow key toggles the hold digital output
When a relay/LED is activated, all the others are disactivated. LEDs are verified
simply by looking at them, while relays can be verified through a multimeter set
for continuity test.
To exit the test press the CFM key and the previous configuration of the relays is
reestablished.

To enter the analog output test procedure confirm
the corresponding option and a start output value
is displayed. This value is let out to the analog out-
put and coincides with the minimum value of the
selected analog output type (item O.11 for ana-
log output 1 and O.21 for analog output 2).
A new output value can be edited manually. Use the up & down arrow keys to
change each digit, and the right arrow to move to the next digit.

Once a value is entered, the corresponding current is immediately erogated by
the selected output and no confirmation is required.
The minimum and maximum values let out are 3.6 and 22 mA for the 4-20 mA
output, or 0 and 22 mA for the 0-20 mA output. This depends on the possibility
of the fault currents to be let out (see "Alarm - error configuration" section).
To verify the erogated current use a multimeter connected to the corresponding
output.

This test is made to verify if the instrument recognizes the digital input signal at
the hold input. To enter the test procedure confirm the "Hold digital input test"
option.
Once the test is confirmed, the display will indicate the status ("Off" or "On") of
the digital input corresponding to the hold command.
Toggle the digital input between high and low levels, and verify the correspond-
ing status on the display.
To exit the test press the CFM key.

To enter the test procedure confirm the "Advanced cleaning digital input test"
option.
Once the test is confirmed, the display will indicate the status ("Off" or "On") of
the digital input corresponding to the advanced cleaning.
Note that if relays #3 and #4 have been configured for the advanced cleaning,
and the cleaning trigger (L.15) is set to "External only" or "timer and external", a
cleaning action will be started when the digital input is on.
To exit the test press the CFM key.
