Default Range Description
52 1800 Proportional Band
The proportional band is set as an offset of above the set TDS target value,
within the proportional band, the PID control will make corrections during
the blowdown time to maintain the TDS target value. If using a solenoid
valve or servomotor (2-state) TDS control, then the P element will determine
how long the valve is fully open for before it goes to fully closed, during the
blowdown time. If using servomotor continuous TDS control, then the P
element will determine what angle the valve is opened to during the
blowdown time. If the measured is above this proportional band, then the
solenoid valve or top blowdown servomotor will remain fully open.
10 – 10000 ppm or μS/cm (see expansion option 41)
53 600 Integral Time
For a slower response, increase the integral time. For a quicker response
with fast changing TDS values, decrease the integral time.
0 Disabled
1 – 1000 Seconds
54 5 Derivative Time
For water level with a quickly changing TDS value in the water, a derivative
time can be added to prevent overshoot.
0 Disabled
1 – 1000 Seconds
55 900 Servo Open Angle
The TDS servomotor closed position is set by zeroing the potentiometer in
commissioning mode. As default the servomotor is set as fully open,
however this setting can be decreased to shorten the operational movement
range of the servomotor.

60 0 Bottom Blowdown Function
To enable bottom blowdown, the bottom blowdown expansion feature must
be unlocked. The bottom blowdown function can be set for up to 4 timed
blowdowns over 24 hours. For setting 1, the timed blowdown output
terminal BB is used with an external solenoid valve. For setting 2, the
bottom blowdown control module is used on terminals 5T+ and 5T-, which
is connected to the bottom blowdown servomotor.
0 Bottom blowdown disabled
1 Bottom blowdown using solenoid
2 Bottom blowdown using Autoflame controller
61 0 Bottom Blowdown Triggering
For setting 0, when the MM does not need a manual trigger for a
blowdown to start when the configured blowdown timing is reached. For
setting 1, a manual trigger is required to start the blowdown when the
configured blowdown timing is reached.
0 Automatic triggering
1 Manual triggering
