*) This setting will only be possible if a data communication module has been
installed in the controller.
Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep both buttons depressed at the same time as you recon nect the supply voltage
Error messages
The controller can give the following messages:
E1
Error message
Errors in the controller
E12
The external reference contribution is outside
the range
E21
Level signal outside the range 1)
E22
Signal from ICM/ICAD outside the range
A1
Alarm message
Upper level limit reached
A2
Lower level limit reached
A3
Alarm level limit reached

1)
If E21 is detected. EKC 347 will force the valve to close or open the valve depending
af n35
If Low presure has been selected. (n35=0)
The valve is forced to fully closed, however if Min. Opening Degree (n33) is higher
than 0 the valve will open to the value of n33
If High presure has been selected. (n35=1)
The valve is forced to fully open, however if Max. Opening Degree (n32) is lower than
100 the valve will open to the value of n32
Define the input signal on terminals 10, 20, 21 (external
