6.11.4 Control of twin-head pumps

Twin-head pumps have a GENI module incorporated
in each terminal box. The modules are internally con-
nected via a wire.
The twin-head pumps are factory-set to the control
mode AUTO and the operating mode "alternating op-
eration", which is described below.
The pump has the following operating modes:
• Alternating operation. Pump operation alter-
nates every 24 hours. If the duty pump stops due
to a fault, the other pump will start.
• Standby operation. One pump is operating con-
tinuously. In order to prevent seizing-up, the other
pump will start at a fixed frequency. If the duty
pump stops due to a fault, the other pump will
start.
The operating mode is selected by means of a me-
chanical contact in each module. The contacts in the
two modules must be set to the same position. If the
contacts are positioned differently, "standby opera-
tion" is selected.

Operating the pump:
Twin-head pumps can be set and operated in the
same way as single-head pumps. The duty pump
uses its setpoint setting, whether it is made by
means of the control panel, via the R100 or via bus.
Note: Both pumps should be set to the same set-
point and control mode. Different settings will result
in different operation when changing between the
two pumps.

6.12 LON module

The LON module offers the possibility of connecting
the pump to a LonWorks network. The module is
used for data transmission between a network and
pumps of the type MAGNA UPE 32-120, 40-120,
50-60 and 65-60.
For further information, see the documentation files
on the floppy disk supplied with the LON module.
6.12.1 Connection to network
Pumps fitted with a LON module are registered by
the LonWorks network in one of the following ways:
• Activate the "Service PIN" button on the module.
Then the module transmits a unique 48 bit
ID-code (Neuron ID), which is registered by the
network.
• The bar code on the module or the additional label
