5.3 Commissioning
WARNING!
Operation of the G-BH100 only:
 with the pump lid assembled
 with the pipes/ hoses connected to
the suction and delivery branches
or
 in case of operation with open
suction or delivery branches
(drawing-in of gases from or dis-
charge of gases into the surround-
ings)
 with a piece of pipe or hose hav-
ing a length of at least 120 mm
connected to the branch in ques-
tion
 with bearing end housing
WARNING!
Do not reach into the G-BH100
through open suction or delivery
branches!
Do not insert any objects into the G-
BH100 through the openings!
i
IMPORTANT!
The G-BH100 must not be operated
with the suction or delivery branches
sealed up or jammed!
WARNING!
Before start-up
 check pipes / hoses and vessels
for sufficient strength!
 check pipe / hose connections for
tightness!
 check fasteners for secure fixing
Proceed as follows:
 Make
sure
- that the suction and delivery pipes are cor-
rectly connected,
- that in case of operation with open suction
or delivery branches (drawing-in of gases
from or discharge of gases into the sur-
roundings)
a piece of pipe or hose having a length of
at least 120 mm is connected to the
branch in question in order to prevent the
impeller from being reached by fingers.
- that the suction and delivery pipes are not
jammed,
- that all fasteners are properly tightened,
- that the correct voltage and current are
applied.
 Set the control voltage serving as speed ref-
erence and applied to n
des
to 0 V at first.
 Turn on the indicated operating voltage.
Now increase the control voltage serving as
speed reference and applied to n
des
(0 to
10 V) to your desired value or the value given
on the data sheet. By means of this speed
control the operating point of the G-BH100 is
adapted to the operating point of the system.
 Check the connections for tightness (ensure
that there is no fluid leakage).
