Evaporator evaporator
evaporator
Pressure transmitter
• Installation of the pressure transmitter is less critical. However, the pressure transmitter should be closer to
the temperature sensor, right after the evaporator and with its head upright. It is a good practice to select
a pressure transmitter with an average load of 40 - 60% of full scale.
• 5 EKEs at maximum are allowed to share the output signal of a ratiometric pressure transmitter.
In order to get a correct acquisition on all the units all the three wires (GND, 5 V and transmitter signal
output) must be routed to every unit.

Power supply
• Power sharing is allowed in EKE controller.
• It is a good practice not to reverse the polarity of the power connection cables.
Selection of the common power supply depends on the total number of sharings and the valve in use.

 Relay Outputs
EKE 1B has 1 relay output:
• Type SPDT relay. Digital Output can be used to connect either a solenoid valve or an alarm.
• The relays cannot be used for the direct connection of capacitive loads such as LEDs and ON/OFF control of
EC motors. All loads with a switch-mode power supply must be connected with a suitable contactor or similar.
Cable length
EKE controller supports the following max. cable length.

Cable length Wire size min. / max.

[m] [m2]
Analog inputs (Current/Voltage) max. 10 0.14 / 1.5
Temperature sensor max. 10 *) –
Stepper valve connection max. 30 0.14 / 1.5
Power supply max. 5 0.2 / 2.5
Digital input max. 10 0.14 / 1.5
Digital output – 0.2 / 2.5
Digital MMI max. 3 over CAN RJ –
Communication bus max. 1000 0.14 / 1.5

Cable and wiring *)

• The max. cable distance between the controller and the valve depends on many factors like shielded/
unshielded cable, the wire size used in the cable, the output power for the controller and EMC.
• Keep controller and sensor wiring well separated from mains wiring.
• Connecting sensors by wires more than the specified length may decrease the accuracy of measured values.

Warning
Separate the sensor and digital input cables as much as possible (at least 10 cm) from the power cables to the
loads to avoid possible electromagnetic disturbance. Never lay power cables and probe cables in the same
conduits (including those in the electrical panels).

Connecting Modbus
• For the MODbus cable, it is best to use 24 AWG shielded twisted-pair cable with a shunt capacitance
of 16 pF/ft and 100Ω impedance.
• The controller provides an insulated RS485 communication interface which is connected to the
RS485 terminals (see connection overview).
• The max. permissible number of devices simultaneously connected to RS485 cable output is 32.
The RS485 cable is of impedance 120 Ω with maximum length of 1000 m.
• Terminal resistors 120 Ω for terminal devices are recommended at both ends.
• The EKE communication frequency (baud rate) can be one of the following: 9600, 19200 or
38400 baud, default 19200 8 E 1.
• The default unit address is 1, which can be changed using parameter “G001 Controller adr.”.

 Stepper Motor Output
• All valves are driven in a bipolar mode with a 24 V supply chopped to control the current (Current driver).
• The stepper motor is connected to the “Stepper Valve” terminals (see terminal assignment) with a standard M12
connection cable.
• To configure stepper motor valves other than Danfoss stepper motor valves, the correct valve parameters must
be set as described in the Valve configuration section (see manual for details).
• The default valve setting in EKE 1B is: none.
• The correct valve must be defined in “Valve configuration”, i.e. parameter I067. An overview of valve types is
given in the “Parameter identification” section.

• The stepper motor is connected to the “Stepper Valve” terminals (see terminal assignment) with a
standard M12 connection cable.
• To configure stepper motor valves other than Danfoss stepper motor valves, the correct valve parameters
must be set as described in the Valve configuration section by selecting user defined valve.

Guideline for long M12 cables on Danfoss stepper motor valves

• Long cables will lead to degradation of performance.
• You can overcome this degradation by changing the settings for the valve driver. This guideline is based on
the cable type being the same type as the standard Danfoss stepper motor cable.

• Steady green = power ON
• Flashing green = data transmission / initialization
• Flashing red = alarm / error condition

• Steady red = valve fully closed
(A) (B) • Flashing green = valve opening
• Steady green = valve fully open
• Both green and red flashing = valve-related alarm

USER INTERFACE
EKE 1B can be setup using one of the following user interfaces:
1. Danfoss KoolProg software
2. Danfoss MMIGRS2 external display
3. Communication bus: Modbus RS485 RTU

KoolProg
KoolProg is a software tool for quickly and easily configuring EKE controllers. It enables you
to make online changes to parameter configuration, copy settings to multiple controllers,
monitor the live status of input/outputs, and quickly analyze controller behavior and
program patterns with a graphical trending tool.
KoolProg Software is available for download free of charge at http://koolprog.danfoss.com.
KoolProg requires a Gateway (code 080G9711) to connect to the PC.
Always use latest KoolProg version and User must check the software version of EKE and
create configuration file in KoolProg for that version. Configuration made with the different
software version should not be copied to controller.

Important note!
To guarantee a reliable USB connection to a host device (e.g. industrial PC), you must:
• Connect terminals R and H on MMIMYK CAN port using a termination wire.
• Place cable holder close to MMIMYK to keep USB connector firmly in place.
• Keep USB cable length < 1 m.
• Place MMIMYK and route USB cable far from noise sources (inverter, motors, contactors etc.)

 Setup wizard via MMIGRS2 display
When all connections to the controller have been made, after the power is switched on, the Danfoss logo will appear
for 5 seconds, then the Home screen will be displayed.
To access the Wizard: press and hold enter to access the Login screen, the commissioning password is 300, scroll down
the Setup and service menu and select “Setup wizard”.

The Wizard workflow is: a. Language selection; b. Application selection; c. Input configuration; and d.
Output configuration.
When using the Setup Wizard, repeat the following sequence for all parameter settings:
a. From Setup wizard, select relevant parameters.
b. Press ENTER to highlight 1st option
c. Scroll with UP / DOWN to your desired option
d. If the selected default value is acceptable, press DOWN to get to the next settings. Otherwise,
press ENTER to set your choice
e. Scroll with DOWN to the next parameter (repeat sequence a. to e.)
Note:
• If you do not have sufficient information to complete the Wizard, leave settings on their default values. To generate
the requested info, you can use Danfoss Coolselector2 software to calculate operating conditions and valve OD for the
same operating point.
• Setup Wizard only covers the most important parameters. If other features are to be enabled
(e.g. Alarm settings, MOP/LOP, etc.), they must be configured separately once the Setup Wizard is done.
Setup Wizard is also available in KoolProg PC tool.
The workflow process is the same as that described above for MMIGRS2 display.
