Setting data
• When this setting is set to "ON", a latch function is added to the
alarm function. Once an alarm goes on, the alarm output is held on
until the power is turned off. Note that the latch is canceled if you
change to setting area 1.
• When the alarm output is set to close in alarm, closed output is held,
and when set to open in alarm, open output is held.
• After changing an alarm 1 to 3 latch setting, a software reset must
be executed or the power turned off and on to make the new setting
take effect.
