PROGRAMMING FUNCTIONS
Set-Points
Output Relay 1 - 2
2 set-points ON-OFF
Independent setting to activate Constant / ON-OFF
mode dosing pumps or On-Off equipment.
Set point adjusts set-point value (ON-OFF mode).
Hysteresis
It selects a measuring range around set-point value,
blocking output relays (ON-OFF mode)
Direct - Reverse
It selects output dosing relay dosing direction.
PWM Proportional mode with
modular pulses
Proportional time/pause pulses output will activate a
Constant / ON-OFF mode dosing pumps or other
equipment.
Delay on set point
It selects a delay time (999 seconds adjustable) before
activating relay output.
Alarm Min / Alarm Max
Alarm function selects alarm Lowest and Highest level
passed which alarm relay will be ON or OFF.
mA output
It allows to select Conductivity (μS) levels corresponding to min. / max mA output analogical signal. It activates a
dosing pump suitable to process a remote mA signal or chart recorder or Data logger.
Calibration Calibration menu for Conductivity sensor.
System
Settings
Flow sensor It activates (ON) or deactivates (OFF) flow sensor (proximity switch) input.
Manual temperature It selects manual temperature compensation. 0÷100°C (Auto-Temp=OFF).
Auto-temperature
Compensation
It compensate the temperature/electrode sensor thus always measuring
the exact value against the current temperature.
