Assembly / Installation - ProMinent DULCOTEST CGE 2-mA-2 ppm Instrucciones De Servicio

Assembly / Installation

Insert sensor into the in-line probe housing:
S Push the O-ring from below over the sensor as far as the terminal block.
DLG
S Place the sensor in the DLG.
S Secure the sensor with packaging.
S Push the O-ring from below over the sensor as far as the terminal block;
DGM
leave a washer in the DGM.
S Place the sensor in the DGM and secure it with a terminal screw until the
O-ring seals: the terminal block determines the depth to which the probe
should be inserted.
6 Installation
When using with external equipment (mA-Variant):
The mA model is a probe with a passive 4-20 mA two-wire interface, i.e. the
power supply is external, i.e. from the controller. When it is connected to a
ProMinent controller (e.g. DULCOMARIN
interface's safety requirements are met automatically.
Observe the following when connecting it to external equipment:
Power source:
Max. load:

TAKE CARE
• Depressurise the system before putting the sensor into
the in-line probe housing. Close the stop valves in front of
and behind the in-line probe housing.
• The probe should be pushed into and pulled out of the in-
line probe housing slowly.
TAKE CARE
• The sensor should be installed in such a way that the
power supply is never interrupted.
• Do not switch off the measuring system if it is not being
operated continuously.
• It may be necessary to delay switching on the dosing
equipment.
TAKE CARE
• Do not allow the power supply to fall below 16 V DC, not even
for a short period. The power source must be able to bear a
minimum load of 35 mA at 16 V DC. Do not switch off the
measuring system if it is not being operated continuously.
It may be necessary to delay switching on the dosing
equipment. If the power supply is too low, the measured
variable will be incorrect and this can lead to a dangerous
chlorine overdose.
• Ensure that nobody else is using the same voltage.
The measuring device and monitor must not use the same
voltage as either the probe or power supply.
