1-6 Limit Control Operation
HIGH LIMIT OPERATION
If Hi. is selected for OUT1, the unit will perform high limit control.
When power is applied the OUT1 relay is de-energized. After 6.5
seconds self-test period, if the process is below the high limit set
point (HSP1), the output 1 relay will be energized and OP1 indicator
will go off. If the process goes above the high 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 falls below the
high 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.
