Do not lift the product by the terminal box.

6.5 Outdoor installation

B3 B14 B5

English (GB)

If you install the motor outdoors, provide the motor with a cover and open the drain holes to avoid condensation on the electronic components. See figures 2 and 3.

When fitting a cover to the motor, observe the guidelines in section 6.4 Ensuring

motor cooling.

The cover must be sufficiently large to ensure that the motor is not exposed to direct sunlight, rain or snow. Grundfos does not supply covers. We therefore recommend that you have a cover built for the specific application. In areas with high humidity, we recommend that you connect the motor permanently to the mains supply and activate the built-in standstill heating function. See section

13.20 "Standstill heating", page 44.

Fig. 2 Examples of covers, not supplied by

Grundfos

In order to maintain the UL mark, additional requirements apply to the equipment. See page 71.

6.6 Drain holes

When the motor is installed in moist surroundings or areas with high humidity, the bottom drain hole must be open. The enclosure class of the motor will then be lower. This helps prevent condensation in the motor as the motor becomes self-venting, and it allows water and humid air to escape.

The motor has a plugged drain hole on the drive side. You can turn the flange 90 ° to both sides or 180 °.

7. Electrical installation

DANGER

Electric shock

Death or serious personal injury

- Switch off the power supply to the motor and to the signal relays. Wait at least 5 minutes before you make any connections in the terminal box. Make sure that the power supply cannot be accidentally switched on.

7.4 Additional protection

DANGER

Electric shock

Death or serious personal injury

- Only use residual-current circuit breakers (ELCB, GFCI, RCD) of type B.

The residual-current circuit breaker must be marked with the following symbol:

The total leakage current of all the electrical equipment in the installation must be taken into account. You find the leakage current of the motor in sections 26.2 Leakage current and 27.2 Leakage

current, AC.

This product can cause a direct current in the protective earth conductor.

Overvoltage and undervoltage protection

Overvoltage and undervoltage may occur in case of unstable power supply or a faulty installation. The motor is stopped if the voltage falls outside the permissible voltage range. The motor restarts automatically when the voltage is again within the permissible voltage range. Therefore, no additional protection relay is required.

The motor is protected against transients from the power supply according to EN 61800-3. In areas with high lightning intensity, we recommend external lightning protection.

Overload protection

If the upper load limit is exceeded, the motor automatically compensates for this by reducing the speed and stops if the overload condition persists.

The motor remains stopped for a set period. After this period, the motor automatically attempts to restart. The overload protection prevents damage to the motor. Consequently, no additional motor protection is required.

Overtemperature protection

The electronic unit has a built-in temperature sensor as an additional protection. When the temperature rises above a certain level, the motor automatically compensates for this by reducing the speed and stops if the temperature keeps rising. The motor remains stopped for a set period. After this period, the motor automatically attempts to restart.

Protection against phase unbalance

Three-phase motors must be connected to a power supply with a quality corresponding to IEC 60146-1-1, class C, to ensure correct motor operation at phase unbalance. This also ensures long life of the components.

7.5 Connection terminals

The descriptions and terminal overviews in this section apply to both single-phase and three-phase motors.

For maximum torques, see section 29.1 Torques.

7.5.1 Connection terminals, advanced functional module, FM 300

The advanced module has these connections:

• three analog inputs

• one analog output

• two dedicated digital inputs

8. Operating conditions

8.1 Maximum number of starts and stops

The number of starts and stops via the power supply must not exceed four times per hour.

When switched on via the power supply, the pump starts after approximately 5 seconds.

If a higher number of starts and stops is desired, use the input for external start-stop when starting or stopping the pump.

When started via an external on/off switch, the pump starts immediately.

8.2 Alternating operation of twin-head pumps

On twin-head pumps, the duty and backup pumps must be alternated on a regular basis, i.e. once a week, to ensure an even distribution of the operating

TM05 3973 1812TM02 8842 0904

hours on both pumps. The pumps alternate automatically. See section 13.43 "Multipump setup"

(Setup of multi-pump system).

If twin-head pumps are used for pumping domestic hot water, the duty and backup pumps must be alternated on a regular basis, i.e. once a day, to avoid blocking of the backup pump due to deposits such as calcareous deposits. As default, the pumps alternate automatically. See section

13.43 "Multipump setup" (Setup of multi-pump

system).

8.3 Ambient temperature

The head of the pump is reduced at decreasing water demand and increased at rising water demand. See fig. 24.

This control mode is especially suitable in systems with relatively large pressure losses in the distribution pipes. The head of the pump increases proportionally to the flow in the system to compensate for the large pressure losses in the distribution pipes.

The setpoint can be set with an accuracy of 0.1 metre. The head against a closed valve is half the setpoint.

Function

Select one of these functions:

•Not active When set to Not active, the input has no function.

• External stop When the input is deactivated, open circuit, the pump stops.

• Min. (minimum speed) When the input is activated, the pump runs at the set minimum speed.

• Max. (maximum speed) When the input is activated, the pump runs at the set maximum speed.

• "User-defined speed" When the input is activated, the motor runs at a speed set by the user.

• External fault When the input is activated, a timer is started. If the input is activated for more than 5 seconds, the pump stops and a fault is indicated. This function depends on input from external equipment.

• Alarm resetting When the input is activated, a possible fault

TM06 4012 1515

indication is reset.

• Dry running When this function has been selected, lack of inlet pressure or water shortage can be detected. When lack of inlet pressure or water shortage, dry running, is detected, the pump stops. The pump cannot restart as long as the input is activated. This requires the use of an accessory, such as:

– a pressure switch installed on the inlet side of

the pump

– a float switch installed on the inlet side of the

pump.

• Accumulated flow When this function has been selected, the accumulated flow can be registered. This requires the use of a flowmeter which gives a feedback signal as a pulse per defined flow of water. See section 13.18 "Pulse flowmeter

setup".

• Predefined setpoint digit 1, applies only to digital input 2.

●

When digital inputs are set to predefined setpoint, the pump operates according to a setpoint based on the combination of the activated digital inputs. See section

The pumps have a factory setting of gain, Kp, and integral time, T

However, if the factory setting is not the optimum setting, you can change the gain and the integral time.

• Set the gain within the range from 0.1 to 20.

• Set the integral time within the range from 0.1 to 3600 seconds. If you select 3600 seconds, the controller functions as a P controller.

Furthermore, you can set the controller to inverse control. This means that if the setpoint is increased, the speed is reduced. In the case of inverse control, the gain must be set within the range from -0.1 to

-20.

13.16 External setpoint function

Pump variant

TPE, TPED, NBE, NBGE, NKE, NKGE

You can influence the setpoint by an external signal, either via one of the analog inputs or, if an advanced functional module is fitted, via one of the Pt100/1000 inputs.

●

Before you can enable the External setpoint function, you must set one of the analog inputs or Pt100/1000 inputs to Setpoint influence.

See sections 13.7 Analog inputs and

13.9 Pt100/1000 inputs.

If more than one input has been set to Setpoint influence, the function selects the analog input with the lowest number, for example Setting of pump, and ignores the other inputs, for example Analog input 3 or "Pt100/1000 input 1".

Example with constant pressure with linear influence

Actual setpoint: actual input signal x (setpoint sensor min.) + sensor min.

At a lower sensor value of 0 bar, a setpoint of 2 bar and an external setpoint of 60 %, the actual setpoint is 0.60 x (2 - 0) + 0 = 1.2 bar.

function

●

"Detection delay"

You can set a detection delay which ensures that the monitored parameter stays above or below a set limit in a set time before the function is activated.

"Resetting delay"

The resetting delay is the time from which the measured parameter differs from the set limit including the set hysteresis band and until the function is reset.

Example

The function is to monitor the outlet pressure of a pump. If the pressure is below 5 bar for more than 5 seconds, a warning must be given. If the outlet pressure is above 7 bar for more than 8 seconds, you must reset the warning.

English (GB)

The function requires setting of the following:

Measured

Here you set the measured parameter to be monitored.

"Limit"

Here you set the limit which activates the function.

"Hysteresis band"

Here you set the hysteresis band.

"Limit exceeded when"

Here you can set the function to be activated when the selected parameter exceeds or drops below the set limit.

• "Above limit" The function is activated if the measured parameter exceeds the set limit.

• "Below limit" The function is activated if the measured parameter drops below the set limit.

Action

If the value exceeds a limit, you can define an action. You can select the following actions:

• "No action" The pump remains in its current state. Use this setting if you only want to have a relay output when the limit is reached. See section

13.12 "Signal relays 1 and 2" (Relay outputs).

• "Warning/alarm" There is a warning.

•Stop The pump stops.

•Min. The pump reduces speed to minimum.

•Max. The pump increases speed to maximum.

• "User-defined speed" The pumps runs at a speed set by the user.

You can use this function to avoid condensation in humid environments. When you set the function to "Active" and the pump is in operating mode Stop, a low AC voltage is applied to the motor windings. The voltage is not high enough to make the motor rotate but ensures that sufficient heat is generated to avoid condensation in the motor including the electronic parts in the drive.

Remember to remove the drain plugs and fit a cover over the motor.

13.21 Motor bearing monitoring

Pump variant "Ramps"

TPE, TPED, NBE, NBGE, NKE, NKGE

TPE, TPED, NBE, NKE Series 2000

The ramps determine how quickly the motor can accelerate and decelerate, respectively, during start-stop or setpoint changes.

You can set the following:

• acceleration time, 0.1 to 300 seconds

• deceleration time, 0.1 to 300 seconds. The times apply to the acceleration from 0 rpm to

fixed maximum speed and the deceleration from fixed maximum speed to 0 rpm.

At short deceleration times, the deceleration of the motor may depend on load and inertia as there is no possibility of actively braking the motor.

If the power supply is switched off, the deceleration of the motor only depends on load and inertia.

13.43 "Multipump setup" (Setup of multi-pump system)

Pump variant "Multipump setup"

TPE, TPED, NBE, NBGE, NKE, NKGE

TPE, TPED, NBE, NKE Series 2000

The multipump function enables the control of two pumps connected in parallel without the use of external controllers. The pumps in a multipump system communicate with each other via the wireless GENIair connection or the wired GENI connection.

A multipump system is set via a selected pump, i.e. the master pump, which is the first selected pump.

If two pumps in the system are configured with an outlet-pressure sensor, both pumps can function as master pumps and take over the master pump function if the other fails. This provides additional redundancy in the multipump system.

The multipump functions are described in the following sections.

●

English (GB)

13.43.1 Alternating operation

English (GB)

Alternating operation functions as a duty/standby operating mode and is possible with two pumps of same size and type connected in parallel. The main purpose of the function is to ensure an even amount of running hours and to ensure that the standby pump takes over if the running pump stops due to an alarm.

Each pump requires a non-return valve in series with the pump.

You can choose between two alternating operation modes:

• "Alternating operation, time" Pump changeover to the other is based on time.

• "Alternating operation, energy" Pump changeover to the other is based on energy consumption.

If the duty pump fails, the other pump takes over automatically.

13.43.2 Backup operation

Backup operation is possible with two pumps of same size and type connected in parallel. Each pump requires a non-return valve in series with the pump.

One pump is operating continuously. The backup pump is operated for a short time each day to prevent seizing up. If the duty pump stops due to a fault, the backup pump starts automatically.

13.43.3 Cascade operation

Cascade operation ensures that the pump performance is automatically adapted to the consumption by switching pumps on or off. The system thus runs as energy-efficiently as possible with a constant pressure and a limited number of pumps.

All pumps in operation run at equal speed. Pump changeover is automatic and depends on energy, operating hours and fault.

If the pump system consists of two to four single-head pumps connected in parallel, the pumps must be of the same type and size. Each pump requires a non-return valve in series with the pump.

Set the control mode to "Constant pressure" or "Constant curve".

This function is available with up to 4 motors installed in parallel. The motors must be of the same size and the pumps must be of the same model.

• The performance is adjusted to the demand through cutting pumps in or out and through parallel control of the pumps in operation.

• The controller maintains a constant pressure through continuous adjustment of the speed of the pumps.

• Pump changeover is automatic and depends on load, operating hours and fault detection.

• All pumps in operation run at the same speed.

• The number of pumps in operation also depends on the energy consumption of the pumps. If only one pump is required, two pumps will run at a lower speed if this results in a lower energy consumption.

• If several motors in the system have a sensor, they can all function as master and take over the master function if the other motors fail.

13.43.4 Setting a multipump system

In systems with relatively large pressure losses in the distribution pipes and in air-conditioning and cooling systems.

• Two-pipe heating systems with thermostatic valves and the following: – very long distribution pipes – strongly throttled balancing valves

Proportional pressure

– differential-pressure regulators – large pressure losses in those parts of the system through which the

total quantity of water flows, for example boiler, heat exchanger and distribution pipe up to the first branching.

• Primary circuit pumps in systems with large pressure losses in the

primary circuit.

• Air-conditioning systems with the following: – heat exchangers, fan coils – cooling ceilings – cooling surfaces.

In systems with relatively small pressure losses in the distribution pipes.

• Two-pipe heating systems with thermostatic valves and the following: – sized for natural circulation – small pressure losses in those parts of the system through which the

total quantity of water flows, for example boiler, heat exchanger and distribution pipe up to the first branching, or modified to a high differential temperature between flow pipe and return pipe, for example district heating.

Constant differential pressure

• Underfloor heating systems with thermostatic valves.

• One-pipe heating systems with thermostatic valves or pipe balancing

valves.

• Primary circuit pumps in systems with small pressure losses in the

primary circuit.

In systems with a fixed system characteristic. Examples:

• one-pipe heating systems

Constant temperature and

constant differential

temperature

• boiler shunts

• systems with three-way valves

• domestic hot-water circulation.

If an external controller is installed, the pump is able to change from one constant curve to another, depending on the value of the external signal.

You can also set the pump to operate according to the maximum or minimum curve, like an uncontrolled pump:

• Use the maximum-curve mode in periods in which a maximum flow is

required. This operating mode is for instance suitable for systems with hot-water priority.

• Use the minimum-curve mode in periods in which a minimum flow is

required.

In systems requiring a constant flow, independently of pressure drop.

Constant flow rate

Examples:

• chillers for air-conditioning

• heating surfaces

• cooling surfaces.

English (GB)

In systems requiring a constant tank level, independently of the flow rate. Examples:

• process-water tanks

• boiler-condensate tanks.

In systems with pumps operating in parallel. The multipump function enables the control of two to four single-head

pumps connected in parallel and twin-head pumps without the use of external controllers. The pumps in a multipump system communicate with each other via the wireless GENIair connection or the wired GENI connection.

15. Bus signal

The pump supports serial communication via an RS-485 input. The communication is carried out according to the Grundfos GENIbus protocol and enables connection to other pumps as well as a building management system or another external control system.

Via a bus signal, you can remote-set pump operating parameters, such as setpoint and operating mode. At the same time, the pump can, via the bus, provide status information about important parameters, such as actual value of control parameter, input power and fault indications.

Contact Grundfos for further information.

If you use a bus signal, the number of settings available via Grundfos GO are reduced.

EMC (electromagnetic compatibility)

Standard used: EN 61800-3. The table below shows the emission category of the

motor. C1 fulfils the requirements for residential areas.

Note: When connected to a public network, 11 kW motors do not comply with the partial weighted harmonic distortion (PWHD) requirements of EN 61000-3-12. If required by the distribution network operator, compliance can be obtained in the following way:

The impedance of the mains cables between the motor and the point of common coupling (PCC) must be equivalent to the impedance of a 50 m cable with a cross-section of 0.5 mm.

C3 fulfils the requirements for industrial areas. Note: When the motors are installed in residential areas, supplementary measures may be required as the motors may cause radio interference.
