the sensor
ProMinent
®
Loosen the M-12 connection and feed the 2-connector cable
through it. Whilst doing this, keep the two-connector signal cable
in the sensor (5 cm).
Strip the insulation from both ends of the cable and connect
to the terminal, as shown in fig. 4 (use the screwdriver provided).
1 = plus, 2 = minus (see fig. 5).
Tighten the M-12 connection.
Turn the upper section of the sensor clockwise firmly as far as
the stop.

Commissioning
CAUTION
• Please note that for regulation tasks, the response time T
is 8 min.!
• The power supply for the measuring equipment and the
sensor must not be interrupted. If power is interrupted for a
long
period
re-started (run-in and calibrate the sensor).
• Do not switch off the measuring system during interval
operation!
After operation without hydrogen peroxide, running-in
periods are to be reckoned with.
If required, switch on metering unit time-delayed. If no
hydrogen peroxide is metered for a longer period of time, the
sensor must be disconnected from the power supply and
stored dry.
