OPERATING FUNCTIONS
O N -O FF m ode
The unit features an ON-OFF mode that enables (or disables if the reverse mode is ON) the output relays of the metering
pumps, peristaltic pumps or other equipment.
ADVANTAGES: it works with the great majority of ON-OFF devices, which are also cost-effective.

The setpoint relays are factory set as follows:
Setpoint 1 CL : DIRECT mode, the output is active when the measured value is lower than the selected setpoint, the metering pump
injects an oxidising solution.
Setpoint 2 CL: REVERSE mode, the output is active when the measured value is higher than the selected setpoint, the metering pump
injects a reducing solution
.

The Alarm function makes it possible to select the minimum and maximum values outside which the instrument triggers an alarm.
ADVANTAGES: increasing safety measures assuring an alert if the parameters are out of control.

Hysteresis is useful during operations to adjust the setpoints in ON-OFF mode and is used to enable or disable the output relays
when the selected hysteresis is achieved. Hysteresis is useful when there are too many quick swings around the setpoint, that might damage
the connected device. By increasing hysteresis it is possible to move away from the setpoint value in accordance with the required value.
