8 Alarms and troubleshooting
Depending on the application, the EKE 1x series implements error codes and alarms to help the user troubleshoot
and correct parameters easily. When an alarm occurs, the following actions generally ensue:
• the “Alarm” or “Warning” relay is activated
• an icon and the alarm code are displayed on the screen
The alarms are reset automatically. The alarm is deactivated as soon as the alarm condition ceases. Otherwise, the
user must follow the deactivation procedure once the alarm conditions is over. When the alarm is eliminated the
alarm, relay is deactivated, and the alarm code will no longer be displayed.

Conguration
error
Auto operation
blocked
Active when: - D12 and D13
have the same mapping cong-
uration. - All and AI5 have the
same mapping conguration.
Correct application settings
One or more
conguration errors is block-
ing operation to start. Check the other ac-
tive alarms to identify the conguration
problem.
E011
No refrigerant selec-
ted
Auto operation

0030 refrigerant set to none
Set 0030 refrigerant set to an
actual refrigerant
No refrigerant is selected,
congure the
correct refrigerant. See "0030 Refrigerant"
E104
SH reference too
close to SH close set
point
Auto operation
blocked
SH close is used and SH close
set pint is too close the actual
reference/ reference minimum
Disable SH close or correct the
actual SH reference / reference
minimum to have 0.5K dier-
ence to SH close set point
SH reference can come to close to the SH
close safety functions et point. which can
result in unstable operation. Keep min.
0.5K separation between minimum SH ref-
erence and N119 SH close set point.
E105
LOP set point too
close to MOP set
point
Auto operation
blocked
If MOP and LOP is used, Mop
set point - Lop set point must >
5K
Disable MOP or LOP, or adjust
the dierence on MOP-LOP set
point >= 5K
The set point for the 2-pressure safety
function Lop and Mop is to close. Keep
min. 5K separation between NO11 MOP
set point and N140 LOP set point
