Important Note

• Mount the sensor on a clean paint-free surface.

• Remember to use heat conducting paste and insulate

the sensor.

• For precise measurements, mount the sensor max. 5 cm from the outlet of the 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 1D has 1 relay output:

• Ty pe SP DT 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 specied 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 CANbus

• For the CANbus cable, it is best to use 24 AWG shielded twisted-pair cable with a shunt capacitance of 16 pF/ft and 100 Ω impedance.

• The controller provides a communication interface which is connected to the RJ and CAN terminals (see connection overview).

• Terminal resistors 120 Ω for terminal devices are recommended at both ends of the bus, Terminal resistance between H and L terminals.

• The default unit address is 1, which can be changed using parameter “G001 Controller adr".

CANbus

H L Not in use

AN325741271542en-000403 | 7

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 congure stepper motor valves other than Danfoss stepper motor valves, the correct valve parameters must be set as described in the Valve conguration section (see manual for details).

• The default valve setting in EKE 1D is: none.

• The correct valve must be dened in “Valve conguration”, i.e. parameter I067. An overview of valve types is given in the “Parameter identication” section.

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 t ype being the same t ype as the standard Danfoss stepper motor cable.

Danfoss MMIGRS2 display

Connecting external MMIGRS2 display

MMIGRS2 display can be used to set up EKE 1D. The display can be used not only for setting up the necessary parameters, but also as an ex ternal display during operation to show impor tant parameters, e.g. degree of opening of valve, superheat, etc.

Important note:

• Max. distance bet ween controller and display is

3 m over CAN RJ.

• CANbus requires termination in both ends of the cable

by a 120 Ohm resistor to ensure reliable communication. On EKE 1D terminate L and H with resistor and on MMIGRS2 terminate R and H with jumper.

• External power for MMIGRS2 is not needed while using

CAN RJ connector. In case of connecting via 3 way screw plug-in connector external power supply is required for MMIGRS2.
