Operation
CAUTION
• The power supply to the measuring device and to the
sensor must not be interrupted. If the power supply is
interrupted (> 2 hours) the sensor must be re-commis-
sioned (see Chapter 8.1).
• Do not switch off the measuring system during interval
operation. After any operation without chlorine, running-
in periods must be reckoned with.
If required, switch on metering unit time-delayed!
If no chlorine is metered for a longer period of time, the
sensor must be disconnected from the power supply and
stored dry.
• The sensor's current signal must not exceed 20 mA.
Otherwise the sensor may be damaged, which may result
in dangerous overdosing within a control system. To
avoid this, install a monitor, which permanently switches
off the chlorine control system and triggers an alarm.
The monitoring equipment must not be automatically
re-setting.
• Once the sensor has been commissioned it must be kept
permanently wet.
