Trouble-shooting and
debugging when the
measuring signal is too low or
irregular
1
Remove air bubbles on the membrane (G) by lifting the
membrane sensor; air bubbles prevent the chlorine from
diffusing through the membrane (G) and distort the
measurement!
Please note
Air bubbles on the electrode shaft (B) and the membrane cap (E)
are normal following the initial startup and subsequent startups
and they disappear by themselves after one or two days.
2
Replenish electrolyte. Open membrane sensor. To do this,
push the elastomer seal (H) to the side so that air can flow in
through the valve opening (F), and only then screw off the
membrane cap (E). Pour out the electrolyte. Wash the
electrode finger (D) and the membrane cap (E) with clean
(distilled) water and dry with a clean paper towel.
Please note
For further procedures, see “Commissioning“. If the membrane
sensor's measuring signal is still too low or irregular, a new
membrane cap (E) must be used. The membrane sensor then
requires a run-in time of approx. one hour, before a calibration can
be carried out.

mA/V input module
The mA/V input module is used for connecting sensors or external
measurements with mA or voltage output signal.
0/4 – 20 mA signal or 0 – 10 V input voltage are possible.
The mA/V input module can be installed in slots 1 to 4. Various
controller functions are available depending on the slot and
application selected. An installed mA/V input module in slot 5
serves to record the flow and external setpoint/dosing factor.
