Tab. 3: IF-Modules
NOTE:
The procedure and further information for commissioning and con-
figuring the IF-Module on the pump can be found in the installation
and operating instructions of the IF-Module used.
6.3.1
Operating modes
Main/standby operation
Each of the two pumps provides the configuration flow rate. The
other pump is available in case of malfunction or runs after pump
cycling. Only one pump runs at a time (see Fig. 15, 16 and 17).
Parallel operation
In the partial load range, the hydraulic output is provided at the
beginning by one pump. The second pump will be switched on when
it is most effective to do this, i.e. when the total power consumptions
P
1
of both pumps in the partial load range is less than the power con-
sumption P
1
of one pump. Both pumps will then be simultaneously
adjusted upwards to the maximum speed. (Fig. 19 and 20).
In manual control mode, both pumps always run synchronously.
Parallel operation of two pumps is only possible with two identical
pump types.
See chapter 6.4 “Other functions” on page 83.
6.3.2
Behaviour in dual pump operation
Pump cycling
In dual pump operation, a pump cycling occurs periodically (the period
can be set; factory setting: 24 h).
Pump cycling can be triggered:
• Internally, time-controlled (menu <5.1.3.2> + <5.1.3.3>)
• Externally (menu <5.1.3.2>) by a positive edge at the “AUX” contact
• Manually, (menu <5.1.3.1>)
