Superheat controller, type EIM 365 (PV01)
Sensor, Valve and Refrigerant Configuration
Pressure Sensor Settings
The pressure sensor input is setup by default to accept an AKS32R pressure transducer. If another sensor is to be
used, it is important to note that it needs to be a 0.5 - 4.5 Vd.c. radiometric type (10% - 90% of supply voltage). The
default range for the sensor is 0 to 16 bar absolute. This can be changed by setting the minimum transducer
pressure "o20 MinTransPres" and the maximum transducer pressure "o21 MaxTransPres" to the new values. The
values must be entered in bar absolute so a sensor with a range of -1 to 12 bar gauge, needs to be defined as 0 to 13
bar absolute.

Symbolic name
o20 MinTransPres
o21 MaxTransPres
 NOTE:
BothDanfoss AKS 32R and Danfoss Saginomiya Pressure transmitter NSK-BExxx follows the relative (gauge) pressure,
therefore same rules apply as explained above in converting and defining it in bar absolute in EIM controller.
Temperature sensor Settings
The temperature sensor input is setup by default to accept PT1000 temperature sensor. The values for the sensor
can be adjusted to calibrate the sensor through the parameter "r09 Adjust S2".
