Installation
(hydraulic)
CAUTION
• Observe the maximum permissible operating parameters of the entire installation of the
DULCOTROL
®
measuring/control station (e.g. pressure, temperature, fl ow rate)!
• Observe the lowest maximum permissible operating parameters of the component parts
of the DULCOTROL
®
measuring/control station and the installed sensors (and their
operating instructions)!
• Please also read the operating instructions of the controllers and fi ttings and any other
existing assemblies such as sensors, sample water pump … !
• Ensure a correct fl ow direction of the sample water.
• The maximum operating pressure (1 bar) may not be exceeded.
• A pressure reducer must be installed.
• Hazards from media under pressure.
• Before starting work at the hydraulical part of the DULCOTROL
®
measuring/control
station, this part is to be depressurised in a controlled way using the sampling valve.
• Wear safety goggles.
Fittings
The bypass fi tting (in-line probe) used depends in particular on the sample water, sometimes also
on the measured variable or the combination of the measured variables. For all clear waters, the
type DGMA with fl ow monitoring, and for contaminated waters, DLG III also with upstream fl ow
monitoring are always used.
Hydraulic Connection, Piping
The hydraulic connection of the sample water is made via a 8x5mm hose connection.
Shut-off ball valves are installed upstream and downstream of the bypass fi tting. Upstream of the
bypass fi tting, the optionally available sample water fi lter will be positioned. The bypass fi ttings
include a sampling valve. For an equipotential bonding circuit, a metal pin is integrated in the
bypass fi ttings (see operating instructions DULCOMETER
®
D1C, Part 1).

Measuring/Control Station
Connect the in-line probe or fi tting to the sample water (see operating instructions of the
in-line probe or documentation of the fi tting).

WARNING
•
Live
parts!
• Disconnect from mains plug before opening the housing.
• De-energise damaged, defective or manipulated units by disconnecting the mains plug.
• The electrical installation of the electrical assemblies may only be performed by a
qualifi ed electrician!
• The controller may only be opened by a qualifi ed electrician!
• With only one controller: Install a mains switch to be able to quickly disconnect from the
mains supply in case of emergency! For stations with two or more controllers, the
switch is installed at the terminal box.
CAUTION
• Please also read the operating instructions of the controllers and fi ttings and any other
existing assemblies such as sensors, sample water pump … !
