The pump is fitted with an three-phase motor with frequency converter and PI-controller
integrated in the motor terminal box.
No additional motor protection is required as both motor and electronics are protected by
integrated overload and temperature protection.

External sensor can be connected if controlled pump operation based on for example flow,
pressure or temperature is required.

A control panel enables setting of required setpoint as well as setting of pump to MIN or
MAX operation or to STOP.
The control panel has indicator lights for "Operation" and "Fault".

Communication with the pump is possible by means of Grundfos R100 Remote Control
enabling further settings as well as reading out of a number of parameters such as "Actual
value", "Speed", "Power input" and total "Power consumption".

The terminal box holds terminals for the connection of:

- Pump start/stop (potential-free contact),

- external remote setpoint setting via analog signal, 0 - 5 V, 0 - 10 V, 0(4) - 20 mA,

- 5 V voltage supply for setpoint potentiometer, Imax = 5 mA,

- sensor, 0 - 5 V, 0 - 10 V, 0(4) - 20 mA,

- 24 V voltage supply for sensor, Imax = 40 mA,

- input for forced control to MIN, MAX, External fault or Flowswitch (potential-free
contact),

- potential-free fault signal relay with changeover contact, reporting Fault, Operation
or Ready,

- RS485 GENIbus.
