9.1.1 How to Select the Reflash Function ON/OFF
Reflash is a function to indicate repeating alarm occurrences among a group of alarms
sharing the same output relay. When the optional alarm output relays are not installed,
data entry will be ignored. Note that only I01 to I03 (which should be assigned in the
alarm setting also) can be used for the reflash function.
The initial value is ‘
OFF
’.
SETTING PROCEDURE:
Enter the SET UP Mode by turning ‘
ON
’ the power while pressing and holding the
ENT
-key until the SET UP display appears.
Use the
UP/DOWN
-keys to select the display ‘
SETUP=ALARM
’. Press the
ENT
-key.
The display ‘
REFLASH=...
’ will appear. Select ON or OFF. Press the
ENT
-key.
The reflash setting has been completed, but has not been stored yet. Before you can
adjust other settings in the SET UP Mode, you have to finish the alarm settings until the
‘*
ALARM SET
*’ display appears.
Before leaving the SET UP Mode, you have to store your new settings. Proceed with the
alarm settings until the display ‘*
ALARM SET
*’ appears. Press the
ESC
-key to return
to the
‘SETUP=ALARM
’ display and then select the ‘
SETUP=END
’ display.
Press the
ENT
-key. Select ‘
END=STORE
’ to keep your new settings or
‘
END=ABORT
’ and press the
ENT
-key. After a few seconds, the Operation Mode will
appear.
NOTE
When I01 to I03 are used for the reflash function, they cannot be used for the AND
function, see 9.1.2.
I01 to I03 will be exclusively used for the reflash function, regardless of the number of
alarm output relays.
