7.3 Overview of features
7.3.1 Display and operation
Great emphasis was placed on easy-to-follow, simple, and intuitive
operation while developing PoolManager
®
. The screen design is also
presented in a modern and attractive manner.
The following is an overview of the significant features and concepts in
the graphic interface.
7.3.2 Measuring and control
pH and redox measurement via single-rod measuring cells
(glass electrodes)
free chlorine / bromine measurement via open potentiostatic
measurement (3-electrode system)
Temperature measurement in the measuring chamber (PT1000
sensor)
2 additional temperature inputs for additional functions (PT1000,
KTY83, or KTY16-6 sensors)
Proportional control for all control modules
Minimum dosing rate provides for additional I-(integral)
contribution, i.e. for reliable attainment of the setpoint.
All important control parameters are individually programmable for
each control module (setpoint, alarm thresholds, proportional
range, dead zone (pH), dosing cycle time, minimum dosing rate,
dosing monitoring)
Continuous display of current dosing rate
Conversion of all measured variables via high resolution 10-bit
A/D converter.
1- or 2-point calibration for pH
Simple and precise 1-point calibration for chlorine / bromine
(PoolManager
®
PRO only)
1-point calibration for redox (mV) and temperature
7.3.3 Safety functions
Extensive monitoring and alarm functions
Upper and lower measured value alarms
Flow monitoring
Level warnings and level alarms (canister level)
Dosing monitoring
(monitoring of the attainment towards the setpoint)
Battery alarm (buffer battery for the real-time clock)
Start delay after turning on PoolManager
®
or after turning
circulation back on
Automatic blocking of dosing in critical alarm states and during
start delay
Alarm signalisation via
Screen display
Acoustic alarm (can be deactivated)
Alarm relay
Continuous monitoring of correct program operation and
automatic reset in the event of an error.
