Products manufactured by GRUNDFOS PUMPS CORPORATION (Grundfos) are warranted to the original user only to be free of defects in material and workmanship for a period of 24 months from date of installation, but not more than 30 months from date of manufacture. Grundfos' liability under this warranty shall be limited to repairing or replacing at Grundfos' option, without charge, F.O.B. Grundfos' factory or authorized service station, any product of Grundfos' manufacture.
5.3 Ensuring motor cooling These installation and operating instructions apply to the Grundfos TPE pumps. The pumps are fitted with frequency-controlled permanent-magnet motors for single-phase or three-phase mains connection. Note In order to ensure sufficient cooling of the motor, the distance (D) between the end of the fan cover and a wall or other fixed objects must always be at least 0.16" (50 mm), irrespective of motor size. See fig. 1. 4.
6.2 Mains supply Carry out the electrical connection according to local regulations. 6.2.1 Single-phase supply voltage Check that the supply voltage and frequency correspond to the values stated on the nameplate. • 1 x 200-240 V - 10 %/+ 10 %, 60 Hz, PE. Warning Check that the supply voltage and frequency correspond to the values stated on the nameplate. Before making any connections in the terminal box, make sure that the power supply has been switched off for at least 5 minutes.
.3 Additional protection • 6.3.1 Single-phase motors 3 x 440-480 V - 10 %/+ 10 %, 60 Hz, PE. Caution Note In order to avoid loose connections, ensure that the terminal block for L1, L2 and L3 is pressed home in its socket when the supply cable has been connected.
6.4 Connection terminals The descriptions and terminal overviews in this section apply to both single-phase and three-phase motors. The advanced functional module is only available as an option. For maximum tightening torques, see section 23.1 Torques. The advanced module has these connections: The number of terminals depends on the functional module (FM). The fitted module can be identified on the motor nameplate. See fig. 8.

6.6.2 Replacing an existing motor • Use screened cables with a cross-sectional area of min. AWG 20 (0.5 mm2) and max. AWG 16 (1.5 mm2) for external on/off switch, digital inputs, setpoint and sensor signals. • • Connect the screens of the cables to frame at both ends with good connection. The screens must be as close as possible to the terminals. See fig. 10. If a screened 2-core cable is used in the existing installation, connect the cable as shown in fig. 12.
Caution The motor must not be installed more than 6562 ft (2000 m) above sea level. Warning The product may be so hot that only the buttons should be touched to avoid burns. Installation altitude is the height above sea level of the installation site. • Motors installed up to 3281 ft (1000 m) above sea level can be loaded 100 %.

11.4 Control mode 11.1 Setpoint Possible control modes: The setpoint for all control modes can be set in this submenu when the desired control mode has been selected. See section 11.4 Control mode. 11.2 Operating mode Possible operating modes: • Normal The pump runs according to the selected control mode. • Stop The pump stops. • Min. The min. curve mode can be used in periods in which a minimum flow is required. • • • Const. pressure (constant pressure) • Const. temp.
11.4.3 Constant differential pressure This control mode ensures a constant temperature. Constant temperature is a comfort control mode that can be used in domestic hot-water systems to control the flow to maintain a constant temperature in the system. See fig. 23. When this control mode is used, no balancing valves must be installed in the system. The pump maintains a constant differential pressure, independently of the flow in the system. See fig. 25.
11.4.5 Constant flow rate The pump maintains a constant differential temperature in the system and the pump performance is controlled according to this. See fig. 27. The pump maintains a constant flow in the system, independently of the head. See fig. 29. H H Q Q set Fig. 29 Constant flow rate Fig.

English (US) 11.9 Relay outputs Function (terminal) 11.11 Controller settings FM 300 (advanced) The pumps have a factory default setting of gain (Kp) and integral time (Ti). Relay output 1 (NC, C1, NO) ● However, if the factory setting is not the optimum setting, the gain and the integral time can be changed: Relay output 2 (NC, C2, NO) ● • Set the gain (Kp) within the range from 0.1 to 20. • Set the integral-action time (Ti) within the range from 0.1 to 3600 s.
Ti t L2 -0.5 10 + 5L2 Set the operating range as follows: • Set the min. speed within the range from fixed min. speed to user-set max. speed. • Set the max. speed within the range from user-set min. speed to fixed max. speed. The range between the user-set min. and max. speeds is the operating range. See fig. 34. Note t t t Speeds below 25 % may result in noise from the shaft seal. 100 % (110 %) L2 L2 = Distance ft (m) between heat exchanger and sensor.
At a lower sensor value of 0 psi, a set setpoint of 29 psi and an external setpoint of 60 %, the actual setpoint is 0.60 x (29 - 0) + 0 = 17.4 psi. Actual setpoint = actual input signal x (setpoint - lower value) + lower value. [PSI] Upper value Actual setpoint Lower value – Linear with Min. In the input signal range from 20 to 100 %, the setpoint is influenced linearly. If the input signal is below 10 %, the pump will change to operating mode "Min.".
"Inverse with Stop" and "Inverse with Min." • – Inverse with Stop In the input signal range from 0 to 80 %, the setpoint is influenced inversely. If the input signal is above 90 %, the pump will change to operating mode "Stop". If the input signal is reduced below 85 %, the operating mode will be changed back to "Normal". See fig. 39. – Inverse with Min. In the input signal range from 0 to 80 %, the setpoint is influenced inversely.
11.15.2 Ramps Seven predefined setpoints can be set and activated by combining the input signals to digital inputs 2, 3 and 4 as shown in the table below. The setting of ramps is only relevant in the case of constant-curve operation.
English (US) 12. Assist 12.1 Setup of multi-pump system The multi-pump function enables the control of pumps connected in parallel pumps without the use of external controllers. The pumps in a multi-pump system communicate with each other via the wireless GENIair connection or the wired GENI connection. A multi-pump system is set up via a selected pump, i.e. the master pump (first selected pump). All Grundfos pumps with a wireless GENIair connection can be connected to the multi-pump system.

English (US) 15. Bus signal The motor enables serial communication via an RS-485 input. The communication is carried out according to the Grundfos GENIbus protocol and enables connection to a building management system or another external control system. Via a bus signal, it is possible to remote-set motor operating parameters, such as setpoint and operating mode.
