    The selector switches enable changeover between the operating 4. Setting by means of control panel modes “alternating operation” (left position) and “standby oper- ation” (right position). At high system temperatures, the pump may be so hot that only the buttons should be touched to avoid The switches in the two terminal boxes must be set to the same burns.

  • Page 11: Setting To Max. Curve Duty

    4.2 Setting to max. curve duty Press “+” continuously to change over to the max. curve 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 flash- ing.

  • Page 12: Setting By Means Of R100

    The R100 communicates with the pump via infra-red light. The transmitter and the receiver are incorporated in the pump control The pump is designed for wireless communication with the panel, fig. 25. GRUNDFOS remote control R100. During communication, the R100 must be pointed at the control Fig. 25 panel.

  • Page 13: Menu Operation

    5.1 Menu • Setpoint signal outside signal range (only 4-20 mA) OPERATION • Dry running When communication between the R100 and the pump has been established, the first display in this menu will appear. • Other fault A fault indication can be reset in this display if the cause of the 5.1.1 Setpoint setting fault has disappeared.

  • Page 14: Display Of Actual Speed

    5.2.4 Display of actual speed Furthermore, it is possible to set the controller to inverse control (if the setpoint is increased, the speed will be reduced). In the case of inverse control, the gain (K ) must be set within the range from –0.1 to –20.

    5.3.3 Selection of external setpoint signal 5.3.7 Selection of function for digital input The input for external setpoint signal can be set to different signal The digital input of the pump (terminal 1, fig. 8, 9,10 or 11) can be types.

  • Page 16: External Forced-Control Signals

    Max. curve 8. Bus signal The pump enables serial communication via an RS-485 input. The communication is carried out according to the GRUNDFOS 7. External setpoint signal bus protocol, GENIbus protocol, and enables connection to a building management system or another external control system.

  • Page 17: Priority Of Settings

    9. Priority of settings The start/stop and digital inputs will influence the number of pos- sible settings. By means of the R100, the pump can always be set to max. curve duty or to stop. If two or more functions are activated at the same time, the pump will operate according to the function with the highest priority.

    10. Indicator lights and signal relay The pump incorporates an output for a potential-free signal via an internal relay. The operating condition of the pump is indicated by the green and The signal output can be set to fault, operating or ready indication red indicator lights on the pump control panel, fig.
