7.1.2 Pump in unregulated operation
Example:
In unregulated-operation mode, the pump performance
is set within the range from min. to max. curve, fig. 20.

7.2 Setting to MAX-characteristic operation

Press continuously to change to the MAX-characteristic
of the pump (top light field flashes). When the top light
field is on, must be pressed for 3 seconds before the
light field starts flashing.
To return to unregulated or regulated operation, press
continuously until the desired setpoint is indicated.

7.3 Setting to MIN-characteristic operation
Press continuously to change to MIN-characteristic of
the pump (bottom light field flashes). When the bottom
light field is on, must be pressed for 3 seconds before
the light field starts flashing.
To return to unregulated or regulated operation, press
continuously until the desired setpoint is indicated.

7.4 Start/stop of pump
Stop the pump by continuously pressing
the light fields are activated and the green indicator light
flashes.
Start the pump by continuously pressing
desired setpoint is indicated.

8. External switching commands

The pump has inputs for the following external
switching commands:
– External ON/OFF
– Digital function
Caution

(terminals 1 and 3 – three-phase pumps)

9. BUS signal

The pump provides serial communication via an RS-485
interface. Communication is according to the GENIbus
protocol, and permits connection to a GLT or similar
system. (Possible types of control on request)
With the BUS signal it is possible to set pump operating
parameters such as reference value, mode of operation,
etc. from a remote point. At the same time the pump can
supply status information via the BUS for important
parameters, such as actual value of control parameter,
power consumption, fault indications, etc.
