―
During the test, the display changes in the order of
“1000->0100->0010->0001”. This change is synchronized with
the J612: EXT ALARM output (ON/OFF).
In ALARM-4 alone, ON/OFF operations are opposite to those of
ALARM-1 to 3.
1000: ALARM-1 (#1-2), 0100: ALARM-2 (#3-4),
0010: ALARM-3 (#5-6), 0001: ALARM-4 (#7-8),
NOTE:
The polarity of ALARM-1 to 4 (ON/OFF) depends on the
setting of “[Menu] -> 3-> 6, 7, 8, 9-> 9: ALARM OUT
POLARITY”.
The setting item is not available on the IMO and A types.
