3.5.2 Functions
The DEPOLOX® Pool Compact is used for mea-
surement and control tasks during the treat-
ment of water in swimming pools and baths
and saline pools:
• free chlorine
• pH value
• ORP (Redox) voltage
• Conductivity
• Temperature
Typical applications:
•
Measurement and control of chlorine, pH
and ORP (Redox) and conductivity in the
swimming pool
• Actuation of dosing pumps or chlorine gas
metering systems
• Monitoring and raising of alarm if limit
values exceeded
• Data visualization
• Data transfer to higher-level systems
For connection to a visualization system, there
is an optional 4-way mA output module, an
RS485 interface and an Ethernet interface with
Modbus TCP and HTTP protocol.
3.5.3 Controller outputs
The electronics module is equipped with an
integrated controller for the chlorine value
and a controller for the pH value and the con-
ductivity.
• The chlorine value is held constant at the
setpoint using PI single feedback closed-
loop control.
• The pH value is held constant at the set-
point using proportional control.
• The conductivity is held constant at the
setpoint using PI single feedback closed-
loop control.
The following controller outputs are supported:
