Priming To Bleeding - ProMinent DULCOMETER Assembly And Operating Instructions Manual

Potential equalisation always has to
be in contact with the measuring
medium. A special potential equalisa‐
tion plug (Order No. 791663) and a
cable (Order No. 818438) are neces‐
sary with fitting DGMa. The potential
equalisation pin is always fitted with
fitting DLG, only the cable
(Order No. 818438) is necessary.
Peculiarities when calibrating
with potential equalisation
When calibrating, immerse the poten‐
tial equalisation pin in the respective
buffer solution, or use the calibration
receptacle which forms part of the
scope of supply of the DGMa fitting.
This calibration receptacle incorpo‐
rates an inbuilt potential equalisation
pin to which you can connect the
potential equalisation line.
Connection of ampero‐
6.3.6.2
metric sensors
Connect the sensor, as described in the
sensor operating instructions, to the corre‐
sponding terminals of the controller, see
Ä Chapter 6.3.2 'Terminal diagram'

pump
If you select the function
[Prime with <OK>] when the pumps are
connected and operable, the pumps con‐
tinue to operate at 100% power for as
long as you press and hold down the
key.
You can use this function, for example, to
transport the feed chemical to the pump,
thereby bleeding the metering line.
