We have identi ed an unfortunate design parameter in the EKE 1P software version 2.14 and older
that under certain circumstances, can cause the product to reset its con guration to factory defaults
after 32,000 hours of operation, followed by a power o . Upon such reset, the most likely outcome is
that an alarm is triggered calling for action, and the controlled valve will not work.
After being factory reset, the controller can be recon gured and will be fully functional again.
To rectify the issue, we recommend updating controller software to 2.15 or newer.
Note: By default, EKE 1P from the box is ready to be used as an extension module for AK-PC 572 with
standard Danfoss valves. With this application EKE 1P requires only wiring on AI4 to select controller
mode (high pressure or receiver valve) and selection one of Danfoss standard valve from AK-PC 572
menu. All other settings in the EKE 1P remain default.
In this case no further actions needed. After 32000 hours of operation and power o , settings will be
reset. But after power on and initialization procedure, EKE 1P will be assigned with mode from AI4 and
AK-PC 572 will write Danfoss valve type set in the controller before. So EKE 1P settings will resume its
work and continue to operate as before.
If EKE 1P is used for other purpose e.g. as driver for AK-CC55 Single Coil or with user de ned valves,
please follow procedure below.
Important: Make a backup of all relevant settings before updating controller!
Disconnect phone cable (code number 080G0075) for the RJ11 CAN port on EKE 1P if any is
connected. Connect the MMIGRS2 display (code number 080G0294) to the RJ11 CAN port on EKE 1P
(it takes can take about 2 minutes).
Connect termination loop between H and R on both Display and EKE driver (it takes about 3 minutes).
When the display is connected the display should read "Data" while the "wheel" is spinning.
When data is uploaded the settings can be accessed by pushing the enter button and hold it down for
a few seconds. The display will probably ask for the Password which is 300 (Supervisor) by default.
If the display is not connecting, try this approach:
1. Hold the Enter button (  ) and X button (X) down on the MMIGRS2 display for 5 seconds allowing
the BIOS main-menu to emerge (the software version of the display is shown brie y) (press X to see
the software version again if needed).
2. Choose the menu "MCX selection"
a. choose the line "Clear UI" and push Enter
b. choose the line "AutoDetect" and push Enter
3. Choose the menu "COM selection"
c. choose the line "CAN" and push Enter
4. Choose the menu "Start-up mode"
d. choose the line "Remote application" and push Enter
5. Choose the menu "CAN"
e. choose the line "Baudrate" and choose the setting "Autobaud" and push Enter
f. choose the line "Node ID" and set the value to "126" and push Enter
g. choose the line "Active Nodes" where active nodes can be seen on the screen – the screen is
updated every 2 seconds ("1" is the controller and "L" is the display address)
6. Go back to the main menu via Escape button (push twice).
7. Choose the menu "Application" and push Enter.
8. Now the display will start a new upload from the controller. This process will take approximately 5
minutes.
(It takes about 3 minutes to check the settings and 5 minutes to upload).
