• When these parameters are 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. The latch is canceled if you move
to setting area 1.
• When the alarm output is set to "Close in alarm," the closed output is
held, and when it is set to "Open in alarm," the open output is held.
• After changing an Alarm 1 to 4 Latch parameter setting, a software
reset must be executed or the power must be turned OFF and ON to
make the new setting take effect.
