FUNCTION
Alarm outputs are normally assigned to the LL, L, H and HH alarms and there is not an output
for the P status. However the P output can be assigned to an output instead of one of the
alarm points (Figure 1).
The alarm output ON except for the P output can be held (Figure 2). Whether the output is
held with the display reading continued to accept measured values, or both output and read-
ing are held, can be selected.
In order to reset the latching, set the latching alarm to "no latching" , turn off the power and
restart, or provide the RESET signal.
The measuring can begin after waiting for the delay time from power on (Figure 3).
The outputs can stand by until the input enters P zone from power on (Figure 4).
An alarm trip when 'S.ERR' is indicated can be set.
