Installation - ProMinent DULCOTEST PAA 1-mA-200 ppm Operating Instructions Manual

Fitting the measuring cell in
the in-line probe housing Ensure you also observe the operation and safety instructions con-
ProMinent ®
tained in the operating instructions manual for the in-line probe
housing!
DLG III Push the O-ring up over the measuring cell as far as the terminal
block.
Put the measuring cell into the DLG III.
Tighten the measuring cell with thread plugs.
DGM Push the O-ring up over the measuring cell as far as the terminal
block; leave a plain washer in the DGM.
Put the measuring cell into the DGM and fit tightly with terminal
screw until the O-ring is sealed: the terminal block determines
the correct depth for fitting the measuring cell.
Information on discontinuous operation
The following installation and process measures must be
implemented if the measuring probes are not always in perma-
nent contact with disinfection solution but rather the probes are
used in a discontinuous process, i.e. in intermittent mode (e.g.
at the rinser):
Disinfection solution must not only permanently flow over the
measuring probe during the rinsing procedure but also over night.
The installation of a small, chemical-resistant centrifugal pump
(e.g. ProMinent vonTaine 0502 PVDF, order number: 1023095) is
recommended, connected to a separate power supply.

Installation

General safety instructions
IMPORTANT
Install the equipment so that the power supply for the controller
never falls below the minimum! A power supply that is too low
causes errors in measured values and can lead to over metering
in a control system!
The measuring cell PAA is a measuring cell with a passive 4-20 mA
two-wire interface. The power is supplied externally or from a mea-
suring and control system. Connection to the DULCOMETER
controller from ProMinent ensures automatic compliance with inter-
face safety requirements.
Additional safety instructions for operation with external equipment:
IMPORTANT
• You may only connect the measuring cell to external equip-
ment after authorisation from ProMinent!
