4.3 Settings

The description of settings applies both to pumps without factory-fitted sensor and to pumps with a factory-fitted pressure sensor.
Setpoint
You can set the desired setpoint in three ways:
• on the pump control panel
• via an input for external setpoint signal
• with the Grundfos wireless R100 remote control or Grundfos GO.
Other settings
Make all other settings with R100 or Grundfos GO. You can read important parameters, such as the
actual value of the control parameter and power consumption, via R100 or Grundfos GO.
If special or customised settings are required, use Grundfos PC Tool. Contact your local Grundfos company for more information.

4.4 Radio communication

This product incorporates a radio module for remote control which is a class 1 device and which you can use anywhere in the EU without restrictions.
For use in USA and Canada, see page 73. Some variants of the product and products sold in
China and Korea have no radio module. This product can communicate with the Grundfos
GO and other products of the same type via the built-in radio module.
In some cases, an external antenna may be required. Only Grundfos-approved external antennas may be connected to this product, and only by a Grundfos-approved installer.

4.5 Battery

A Li-ion battery is fitted in CRE, CRIE, CRNE, SPKE and MTRE pumps. The Li-ion battery complies with the Battery Directive (2006/66/EC). The battery does not contain mercury, lead and cadmium.

In order to maintain the UL mark, additional requirements apply to the equipment. See page 73.

6.3 Cable entries

See the size of the cable entries in section 29. Other
technical data.

6.4 Cable glands

The number and size of cable glands delivered with the pump depends on the motor size. See section
29. Other technical data.

6.5 Ensuring motor cooling

Leave at least 50 mm between the end of the fan cover and a wall or other fixed objects. See fig. 1.
Fig. 1 Minimum distance (D) from the motor to
a wall or other fixed objects

6.6 Outdoor installation

If you install the motor outdoors, provide the motor with a suitable 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 guideline in section 6.5 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
13.22 Standstill heating, page 48.
Fig. 2 Examples of covers (not supplied by
Grundfos)
In order to maintain the UL mark, additional requirements apply to the equipment. See page 73.

6.7 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
TM05 5236 3512
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 °.

7.4 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- and three-phase motors.
For maximum torques, see section Torques, page
71.
7.5.1 Connection terminals, CRE, CRIE, CRNE, SPKE and MTRE pumps
CRE, CRIE, CRNE, SPKE and MTRE pumps have a number of inputs and outputs enabling the pumps to be used in advanced applications where many inputs and outputs are required.
The pumps have these connections:
• three analog inputs
• one analog output
• two dedicated digital inputs

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

8.2 Ambient temperature

Minimum -20 °C -20 °C Maximum 40 °C 50 °C
The motor can operate with the rated power output (P2) at 50 °C, but continuous operation at higher temperatures reduces the expected product life. If the motor is to operate at ambient temperatures between 50 and 60 °C, select an oversized motor. Contact Grundfos for further information.

8.3 Installation altitude

Installation altitude is the height above sea level of the installation site.
Motors installed up to 1000 m above sea level can be loaded 100 %.
The motors can be installed up to 3500 m above sea level.
Motors installed more than 1000 m above sea level must not be fully loaded due to the low density and consequent low cooling effect of the air.

• 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 is stopped and a fault is indicated. This function depends on input from external equipment.
• Alarm resetting. When the input is activated, a possible fault indication is reset.
• Dry running. When this function is 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 is stopped. The pump cannot restart as long as the input is activated. This requires the use of an accessory, such as these:
– 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 is selected, the accumulated flow can be registered. This requires the use of a flowmeter which can give a feedback signal as a pulse per defined volume of water. See section
13.20 "Pulse flowmeter" (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 default setting of gain (Kp) and integral time (T
).
i
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-action 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 you increase the setpoint, the speed is reduced. In the case of inverse control, you must set the gain within the range from -0.1 to -20.

13.13 Operating range

Pump variant Operating range
CME CRE, CRIE, CRNE,
SPKE, MTRE
Set the operating range as follows:
• Set the minimum speed within the range from fixed minimum speed to user-set maximum speed.
• Set the maximum speed within the range from user-set minimum speed to fixed maximum speed.
The range between the user-set minimum and maximum speeds is the operating range. See fig. 44.

13.14 External setpoint function

Pump variant
CME CRE, CRIE, CRNE,
SPKE, MTRE
You can influence the setpoint by an external signal, either via one of the analog inputs or, if an advanced functional module (FM 300) is fitted, via one of the Pt100/1000 inputs.
Before you can enable the function, you must set one of the analog inputs or Pt100/1000 inputs to External setpoint function.
See sections 13.6 Analog inputs and
13.7 Pt100/1000 inputs.
Example with constant pressure with linear influence
Actual setpoint: actual input signal x (setpoint ­sensor min.) + sensor min.
At a sensor min. 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. See fig. 45.

Limit-exceeded
function
CME CRE, CRIE, CRNE,

This function can monitor a measured parameter or one of the internal values such as speed, motor load or motor current. If a set limit is reached, a selected action can take place. You can set two limit-exceeded functions meaning that you can monitor two parameters or two limits of the same parameter simultaneously.
The function requires setting of the following:
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 from a CRE 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, reset the limit exceeded warning.
"Measured"
Here you set the measured parameter which is 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 if you want the function to activate 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 set 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
13.10 "Signal relays" 1 and 2 (Relay outputs).
• Warning/alarm. A warning is given.
• Stop. The pump stops.

You can enable the function of the LiqTec sensors in this display. A LiqTec sensor protects the pump against dry running.
The function requires that a LiqTec sensor has been fitted and connected to the pump.
When you have enabled the LiqTec function, it stops the pump if dry running occurs. Restart the pump manually if it has been stopped due to dry running.

"Stop function"
(Low-flow stop function)
The advantages of enabling the "Low-flow stop function" are the following:
• no unnecessary heating of the pumped liquid
• reduced wear of the shaft seals
• reduced noise from operation. The disadvantages of enabling the "Low-flow stop
function" may be the following:
• The delivered pressure is not completely constant as it fluctuates between the start and stop pressures.
• The frequent starts/stops of the pump may in some applications cause acoustic noise.
The impact of the above disadvantages very much depends on the setting selected for the stop function.
The High-comfort mode setting minimises pressure fluctuations and acoustic noise.
Select Energy-optimal mode if the main priority is to reduce the energy consumption as much as possible.
Possible settings of the stop function:
• Energy-optimal mode The pump automatically adjusts the parameters for the stop function so that the energy consumption during the start-stop operation period is minimised. In this case, the stop function uses the factory-set values of the minimum flow (Q and other internal parameters. See fig. 52.

)
• High-comfort mode: The pump automatically adjusts the parameters for the stop function so that the disturbances during the start-stop operation period are minimised. In this case, the stop function uses the factory-set values of the minimum flow (Q and other internal parameters. See fig. 52.

mode), H has been factory-set to 10 % of the actual setpoint. H can be set within the range from 5 to 30 % of actual setpoint.
The pump changes to start-stop operation if the flow becomes lower than the minimum flow.
The minimum flow is set in % of the nominal flow of the pump (see the pump nameplate).
In "User-defined mode" (Customised operating mode), the minimum flow has been factory-set to 10 % of nominal flow.
Factory setting
See section 24. Factory settings.
"Low-flow detection"
Low flow can be detected in two ways:
1. A built-in low-flow detection function which is active if none of the digital inputs are set for flow switch.
2. A flow switch connected to one of the digital inputs.
1. Low-flow detection function: The pump checks the flow regularly by reducing the speed for a short time. If there is no or only a small change in pressure, this means that there is low flow. The speed is increased until the stop pressure (actual setpoint + 0.5 x ΔH) is reached and the pump stops. When the pressure has fallen to the start pressure (actual setpoint - 0.5 x ΔH), the pump restarts.
– If the flow is higher than the set minimum flow,
the pump returns to continuous operation at constant pressure.
– If the flow is still lower than the set minimum
flow (Q operation until the flow is higher than the set minimum flow (Q than the set minimum flow rate (Q pump returns to continuous operation.
2. Flow switch: When the digital input is activated for more than 5 seconds because there is low flow, the speed is increased until the stop pressure (actual setpoint + 0.5 x ΔH) is reached, and the pump stops. When the pressure has fallen to start pressure, the pump restarts. If there is still no flow, the pump quickly reaches the stop pressure and stops. If there is flow, the pump continues operating according to the setpoint.

13.19 Pipe filling function

Pump variant Pipe filling function
CME CRE, CRIE, CRNE,
SPKE, MTRE
This function is typically used in pressure-boosting applications and ensures a smooth startup of systems with for instance empty pipes.
Startup takes place in two phases. See fig. 55.
1. Filling phase. The pipes are slowly filled with water. When the pressure sensor of the system detects that the pipes have been filled, phase two begins.
2. Pressure build-up phase. The system pressure is increased until the setpoint is reached. The pressure build-up takes place over a pressure build-up time. If the setpoint is not reached within a given time, a warning or an alarm can be given, and the pumps can be stopped at the same time.
Fig. 55 Filling and pressure build-up phases
Setting range
• "Filling speed". Fixed speed of the pump during the filling phase.
• "filling pressure". The pressure that the pump must reach before the maximum filling time.
• "max. filling time". The time in which the pump must reach the filling pressure.
• Max. time reaction. Reaction of the pump if the maximum filling time is exceeded:
– warning – alarm (pump stops).
• Pressure build-up time. Ramp time from when the filling pressure is reached until the setpoint must be reached.
When you activate this function, the function always starts when the pump has been in operating mode "Stop" and is changed to "Normal".

13.21 Ramps

Pump variant Ramps
CME CRE, CRIE, CRNE,
SPKE, MTRE
The ramps determine how quickly the pump can accelerate and decelerate 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
maximum (fixed) speed and the deceleration from maximum (fixed) speed to 0 rpm, respectively.
At short deceleration times, the deceleration of the pump may depend on load and inertia as there is no possibility of actively braking the pump.
If the power supply is switched off, the deceleration of the pump only depends on load and inertia.

13.22 Standstill heating

Pump variant Standstill heating
CME CRE, CRIE, CRNE,
SPKE, MTRE
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.
Factory setting
See section 24. Factory settings.

13.23 Motor bearing monitoring

You can set the motor bearing monitoring function to these values:
•Active
•Not active.
When the function is set to Active, a counter in the controller starts counting the mileage of the bearings.
The counter continues counting even if the function is changed to Not active, but a warning will not be given when it is time for replacement.
When the function is changed to Active again, the accumulated mileage is again used to calculate the replacement time.

13.45 "Multi-pump setup" (Setup of
multi-pump system)
Pump variant
CME CRE, CRIE, CRNE,
SPKE, MTRE
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.
You can set a multipump system via the master pump, i.e. the first selected pump.
If two pumps in the system are configured with an outlet-pressure sensor, they can all function as master pumps and take over the master pump function if the other should fail. This provides additional redundancy in the multipump system.
The multipump functions are described in the following sections.
13.45.1 "Alternating operation"
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 starts if the duty 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" Change from one pump to the other is based on time.
• "Alternating operation, energy" Change from one pump to the other is based on energy consumption.
If the duty pump fails, the other pump starts.

(Setup of multi-pump
system)

13.45.2 "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.
13.45.3 Setting up a multipump system

29. Other technical data

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.
