7.6.5 Pump number
A number between 1 and 64 can be allocated to a
pump or can be changed so that the R100 or Pump
Management System 2000 can distinguish between
two or more pumps.
The Pump Management System 2000 can, however,
only accept the numbers 1 to 8.
7.6.6 Twin-head pump
3
This display offers the following options:
Selection of operating mode for twin-head pump:
If field 1 reads "Twin", field 2 offers the choice be-
tween three operating modes:
• Alternating (alternating operation),
• Synchron. (synchronous operation),
• Standby (standby operation).
Description of function, se section 6.1 Control of
twin-head pumps .
Setting the pump to single-pump operation:
In the single-pump operation mode, the master and
slave pumps run independently of each other without
internal communication and with a sensor each.
To set the pump to this operating mode, the commu-
nication between master and slave is to be discon-
nected in one of the following ways:
1. If the master and slave pumps are connected
correctly:
1. Point the R100 at the master pump.
2. Choose "Single" in field 1.
3. Press "OK".
2. If there is a fault in the master-slave communi-
cation (red indicator lights of both pumps are
on):
1. Point the R100 at the master pump.
2. Choose "Single" in field 1.
3. Press "OK".
The master pump will now be running
like an ordinary single-head pump and
the red indicator light will go out.
4. Switch the R100 off and on again.
5. Point the R100 at the slave pump.
Field 1 is already reading "Single".
6. Press "OK" twice in field 1.
The slave pump is now running like a
single-head pump.

The slave pump will now be running according to the
factory settings unless its settings have been
changed.
Setting the pump to twin-pump operation:
If the pump is running like a single-head pump, the
communication can be restored in the following way:
1. Check that the bus cable between master and
slave pump is connected to the pump heads.
2. Check that both pump heads are connected to
the mains supply.
3. Check that the operating mode of the slave pump
is "Normal".
4. Check that the slave pump has been set to
"Single" in the display "Twin-head pump".
5. Point the R100 at the master pump.
6. Choose "Twin" in field 1.
7. Press "OK".
After a short while, the green indicator light on
1
the slave pump will start flashing rapidly for 5
seconds, indicating that the pump is ready to be
the slave pump of a twin-head pump. (If the pump
is installed in a bus system with many pumps, the
2
green indicator lights of all possible slave pumps
in the system will start flashing.)
8. Press "+" or "–" on the control panel of the se-
lected slave pump (while the light is flashing *).
The light fields of the slave pump will go out and
the green indicator light will be flashing 20 times
per minute to indicate that correct connection has
been established.
* If correct connection was not established because
5 seconds passed before "+" or "–" was pressed,
the red indicator light of the master pump will be
on. Go through the procedure all over again to es-
tablish connection.
Confirmation of correct connection:
1. Point the R100 at the master pump.
2. Press "OK" in field 3.
If the connection has been correctly established,
the green indicator light on the slave pump will be
flashing rapidly to indicate this.
