5.2 Hydro 2000 F with a PMU 2000
To start up a booster set Hydro 2000 F with a PMU 2000, follow
this procedure:
1. Pull out the connection plug (BUS) in the PMU 2000, see fig.
28, and proceed according to points 1 to 8 in section
5.1 Hydro 2000 F without a PMU 2000.
Fig. 28
2. Plug the connection plug (BUS) into the PMU 2000.
3. Allocate all pumps to the same zone (display 101).
4. Move from “presetting” (display 102) to display 111. For quick
setting-up of a Hydro 2000 F with a PMU 2000, select preset-
ting:
•
Select “pressure” for booster sets without pre-pressure
measuring (PFU 7).
•
Select “pressure with pre-pressure measuring” for booster
sets with pre-pressure measuring (PFU 8).
Further adjustment can be carried out later on.
The presettings are based on a 4-20 mA transmitter
(0-10 bar). If transmitters with other signal ranges are used,
please adjust accordingly.
5. In the presetting, “setpoint max.” is set to 5 bar which can be
changed to the required level in display 200.
6. Release the pumps for operation in display 300.
7. If Hydro 2000 F is to be operated without a PMU 2000, it can
operate either on the basis of the EPROM settings in the
PFU 2000 (DIP switch 1, contact 5 ON) or on the basis of the
data stored in the PFU 2000 RAM (DIP switch 1, contact 5
OFF).
5.3 Direction of rotation
The Control 2000 F has been wired for equal direction of rotation
for all motors.
The motors must rotate in the correct direction. Check the direc-
tion of rotation by manually switching the pumps on and off one
by one.
•
In case of wrong direction of rotation of all mains-operated mo-
tors, interchange two phases at the mains supply terminals.
•
In case of wrong direction of rotation of the speed-controlled
motor, change the direction of rotation at the frequency con-
verter.
•
In case of wrong direction of rotation of all motors, interchange
two phases at each motor.
Hydro 2000 F is now ready for operation.

3.1.5 Manual on/off and setting to max. or local.

5. Start-up
5.1 Hydro 2000 F without a PMU 2000
To start up a booster set Hydro 2000 F without a PMU 2000, fol-
low this procedure:
1. Check that the booster set corresponds to the one that was or-
dered and that no single parts have been damaged.
2. Connect water and electricity supplies.
Check that the wire cross-section corresponds to the specifi-
cations in the wiring diagram.
Switch off the automatic circuit breakers of all pumps.
3. Close the discharge valves of the pumps and prime the
booster set and the suction pipe.
Check that the pressure in the diaphragm tank is 0.7 times the
required discharge pressure (setpoint).
4. Turn the function selector in the PFU 2000 to “MAX”.
Switch on the automatic circuit breaker of pump 1.
Switch on the automatic circuit breaker for the control current.
After approx. 15 secs., motor 1 will start.
Vent the pump while slowly opening its discharge valve.
Repeat this procedure for all pumps.
Fig. 27
5. Hydro 2000 F has now been vented and is ready for running-
in. Check that the DIP switches in the PFU 2000 have been set
correctly.
6. Turn the function selector to 50%. The booster set will now
start. Establish a consumption of approx. 50% of the perform-
ance of one pump and await stable operation.
7. Adjust the function selector slowly until the required discharge
pressure can be read on the pressure gauge.
Note: When changing the discharge pressure, change the dia-
phragm tank precharge pressure accordingly.
8. Check that the pumps cut in and out and adjust the perform-
ance to the consumption.
Hydro 2000 F is now ready for operation.
5.1.1 Setting via a temporarily connected
PMU 2000
The factory-set standard values in the PFU 2000 RAM can be
changed via a temporarily connected PMU 2000.
