Two selectable chlorine level setpoints can be set by the op-
erator: a proportional dosing setpoint and an alarm setpoint.
Both setpoints control a SPDT relay.
The proportional dosing setpoint analyzers is user-selectable
with a delta from 0.1 to 2.0 mg/L (ppm).
The alarm level can be set by the user to be an “activate-
if-lower-than” setpoint or an “activate-if-greater-than” setpoint.
A system alarm feature provides relay activation to signal
need for operator intervention.
The PCA 300 and PCA 301 analyzers can supply data to
an external computer through an RS232C output connec-
tion.
Voltage output levels of 0-10mV, 0-100mV, 0-1V or a cur-
rent output of 4-20 mA are selectable to drive an external
device such as a chart recorder or an external regulator.
Recorder span minimum and maximum values in mg/L
are programmable by the operator through the keyboard.
