8.4.1 Limiting the volume flow

If there is excess supply from the differential pressure control (Δp-c, Δp-v), the
maximum volume flow can be limited to 25%-90% of Qmax by means of the IR
operating and service unit (accessory). (Pump software status SW ≥ 6.0). When
the set value is reached, the pump is controlled on the pump curve along the limit
- never beyond.
NOTE: "Q-Limit" can only be set using the IR operating and service unit (accessory).
If "Q-Limit" is used in non-hydraulically balanced systems, partial areas can be
undersupplied. Perform hydraulic balancing.
8.5 Operation
Faults of electronic devices due to electromagnetic fields
Electromagnetic fields are created during the operation of pumps with fre-
quency converter. Interference of electronic devices may be the result. The
result may be a device malfunction, which can result in damage to the health or
even death, e.g. of persons carrying implanted active or passive medical devices.
Therefore, during operation the presence of any persons e.g. with cardiac pace-
makers in the vicinity of the unit/pump should be prohibited. With magnetic or
electronic data media, the loss of data is possible.

8.6 Decommissioning

The pump must be decommissioned before conducting maintenance, repair or
dismantling work.
DANGER! Risk of fatal injury!
An electric shock may occur when working on electrical equipment.
• Have work on the electrical part of the pump carried out only by a qualified
electrician as a basic principle.
• Before starting any maintenance and repair work, disconnect the pump from
the power supply, and make sure it cannot be switched back on by unauthor-
ised persons.
• Work on the module may only be started once 5 minutes have passed, due to
the dangerous residual contact voltage (capacitors).
• Check to ensure that all connections (including potential-free contacts) are
voltage-free.
• The pump may still be live even in voltage-free state. The drive rotor induces
a dangerous contact voltage at the motor contacts.
Close the check valves in front of and behind the pump.
• If the control module is damaged, the pump must not be put into operation.
WARNING! Risk of burns!
Touching the pump can cause burns! Depending on the operating status of
the pump or unit (fluid temperature), the entire pump can become very hot.
Allow the unit and pump to cool down to room temperature.
