- Secure the product to a solid foundation
by bolts through the holes in the flange
or the base plate.
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. 1Minimum 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. 2Examples 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
• two configurable digital inputs or open-collector
outputs
• Grundfos Digital Sensor input and output
• two Pt100/1000 inputs
• two LiqTec sensor inputs

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 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
13.15 Predefined setpoints.
The priority of the selected functions in relation to
each other appears from section 15. Priority of

The pumps have a factory default 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-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.

You can set and activate seven predefined setpoints
by combining the input signals to digital inputs 2, 3
and 4. See the table below.
Set the digital inputs 2, 3 and 4 to Predefined
setpoints if all seven predefined setpoints are to be
used. You can also set one or two of the digital inputs
to Predefined setpoints but this limits the number of
predefined setpoints available.
●
Example
Figure 50 shows how you can use the digital inputs
to set seven predefined setpoints. Digital input 2 is
open and digital inputs 3 and 4 are closed. If you
compare with the table above, you can see that
Predefined setpoint 6 is activated.
Fig. 50 Principle sketch showing how
If all digital inputs are open, the pump stops or runs
TM06 4170 1615
at the normal setpoint. Set the desired action with
Grundfos GO or with the advanced control panel.
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.

"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

and other internal parameters. See fig. 52.

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.

Set the minimum flow (Q
setting determines at which flow rate the system is to
change from continuous operation at constant
pressure to start-stop operation. The setting range is
5 to 30 % of rated flow.
The stop function requires a diaphragm tank of a
certain minimum size. Set the size of the installed
tank in this display.
In order to reduce the number of start-stops per hour
or to reduce the ∆H, install a larger tank.
Install the tank immediately after the pump. The

13.19 Pipe filling function
Pump variantPipe 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".

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.

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.

•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.

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.

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.

14. 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 R100 or Grundfos
GO are reduced.
