7.9 Adjusting the settings
7.9.1 Setting the set pressure
The unit’s default setting equals the set pressure indicated on
the rating plate.
If the setpoint needs to be adjusted to the site conditions,
parameter
3-5-1 has to be changed.
First, enter the customer password as described under 7.5.2.1
Access levels - customer. Then change the setpoint as
described under 7.5.2.2.
7.9.2 Further settings
If any further settings have to be adjusted to the site conditions,
change their parameters as described in section 7.5.2.2. Refer
to section 7.5.2 for the menu structure.
7.10 Remote-OFF connection
The remote-OFF connection is a NC contact. When this contact
opens, alle pumps which are in operation will be sequenced
out after the set delay.
When this contact is closed, the pumps will start up again in
line with the demand.
7.11 Fire alarm connection
The fire alarm connection is a NC contact. When this contact
opens, all pumps are started up one after the other after the
set cut-in delay and an alarm signal (red LED) is shown. The
dry running protection and remote-OFF functions are ignored.
When this contact is closed, the pumps will stop again in line
with the demand. The alert is cleared.
7.12 Shutdown
As long as the unit is out of operation, water is supplied directly
through the unit at inlet pressure.
- Set master switch to “0”.
- For prolonged shutdown, drain the unit.
8 Dismantling / reassembling the
pumps
The pumps can be individually dismantled to facilitate
maintenance.
Dismantling sequence :
1. Disconnect the pump from the power supply.
De-energize the pump via the motor protection switch.
2. Close the suction and discharge side valves.
Reassembly :
1. Insert pump (original spare part only), always use new
gaskets for unions and tighten. Check tightness of screwed
connection !
2. Fasten the pump foot to the baseplate using hexagon head
bolts.
3. Connect to power supply, switch on motor protection switch.
9 Returning to service
Return the unit to service as described under Commissioning/
start-up.
10 Maintenance
10.1 Operation monitoring
All technical systems require a certain degree of monitoring.
The same applies to our package units for which the following
checks and inspections are prescribed :
- Check the unit’s readiness for operation.
- Check the operation check run, if activated.
- With the aid of the pressure gauge, compare the start and
stop pressures of the pumps against the data on the name
plate.
- The pump’s mechanical seal allows little or no visible
leakage. It is maintenance-free.
- The motor requires practically no maintenance.
- Verify whether the accumulator pre-charge pressure
corresponds to the data in the pre-charge pressure table
(see section 14). Close the shut-off elements under the
accumulator for this purpose and drain the accumulator
via the drain valve. Remove the protective cap of the
accumulator valve and check the pressure with the aid of a
tyre pressure gauge. Add nitrogen as necessary.
Do not add any other gases.
11 Work on the control cabinet
Each pump can be switched off via the motor protection
switch.
The motor protection switches can be locked with a
padlock as a standard.
The pumps can be stopped by using the manual-0-
automatic switch (supplementary equipment).
However, this will
not disconnect the system from
the power supply , i.e. all electric devices are still live,
even if the pumps are not in automatic operation mode.
Prior to working on the control cabinet or opening the
motor terminal box, set the master switch to “0” and
unscrew the back-up fuse.
Do not tamper with the control unit, which should only be
serviced by KSB’s customer service.
Prior to opening any electric equipment such as control
cabinet and motor terminal box, de-energize the unit.
Even when the mains lamp goes out, check whether all
phases are actually dead prior to performing any work on
the control cabinet.
Control cabinet maintenance
It is recommended to have the control cabinet serviced once a
year. For this purpose you can take out a maintenance contract
with one of KSB’s Service Partners.
