LOW LIMIT OPERATION
LOW LIMIT OPERATION
If Lo. is selected for OUT1, the unit will perform low limit control. When
power is applied the OUT1 relay is de-energized. After 6.5 seconds self-
test period, if the process is above the low limit set point (LSP1), the
output 1 relay will be energized and OP1 indicator will go off. If the
process goes below the low limit set point, the relay will be de-
energized, the OP1 indicator will go on and the display will show the
process value. After the process rises above the low limit set point and
the RESET key is pressed or the remote reset input is applied, the relay
will be energized and the OP1 indicator will go off.
