Default Range Description
45 1000 TDS Adjustment
This value will automatically display the adjustment factor when the TDS
probe is recalibrated during running.
10 – 999 0.010 – 9.999
46 0 TDS Warning Level
The TDS warning level is an absolute limit; if the average TDS reading
taken from the measurement time is higher than this TDS limit, a warning
will be generated. This limit should not be set lower than the target TDS
value set in expansion option 42.
0 Disabled
1 – 5000 ppm or μS/cm (see expansion option 41)
47 10 Pressure Threshold
This pressure threshold is an offset below the required pressure setpoint. If
the actual pressure is below this offset pressure, then TDS control will not
operate.
0 Disabled
1 – 100 PSI or 0.1 bar or 0.01 bar for low pressure sensor (depends on load
detector set in option 1 and metric/imperial units set in parameter 40)
48 25 Sample Time
The first stage of the TDS control cycle is the sample time, where the
solenoid valve or top blowdown servomotor is fully opened to take a
sample.
2 – 60 Seconds
49 25 Settle Time
The second stage of the TDS control cycle is the settle time. Following taking
a sample time in expansion option 48, the solenoid valve or top blowdown
servomotor goes fully closed to allow the sample to stabilise for this settle
time.
2 – 60 Seconds
50 10 Measurement Time
The third stage of the TDS control cycle is the measurement time. Following
the settle time in expansion option 49, TDS probe will a measure the TDS in
the sample every second set in the measurement time. The average across
these measurements is taken as the TDS reading for that cycle. A longer
measurement time will allow an average to be taken over more TDS probe
measurements, and so the TDS readings will be smooth.
2 – 30 Seconds
51 600 Blowdown Time
The final stage of the TDS control cycle is the blowdown time. Following the
measurement time in expansion option 50, if the measured reading is less
than 100ppm below the target value, the solenoid valve or top blowdown
servomotor will remain closed for the duration of the blowdown time. If the
measure reading is higher than the target TDS value, the PID control will
operate.
10 – 1200 Seconds
