operating modes with refrigerant (for use with Ziehl-Abegg pressure sensor type
DSF2-25)
Upon input of the refrigerant, the device automatically calculates the corresponding temperature
for the measured pressure. The settings for offset, target value and the controlling range are
then carried out in °C or K.

No further settings are necessary for pressure sensors from Ziehl-Abegg model DSF2-25 (measurement range 2-25 bar).
In the case of sensors with other measurement ranges, the „E1 Min value“ and the „E1 Max Value“ must be entered in °C.
To do this, convert the bar values for min and max into °C.
8.4.2 Function analog Input 2 (Analog IN 2 ) second Sensor, external Setpoint, extern manual operation
The function is automatically jointly programmed in operating modes using 2 sensors. The second
analog input is thus allocated and additional function allocations are not possible.

Possible functions with a free analog input 2 (Analog In 2)
External Setpoint or external speed setting in manual operation with a 0-10 V (0-20 mA, 4-20 mA) signal is possible on
the „E2" and „GND" terminals. Correspondingly insert jumpers E2.1 and E2.2 for analog IN 2 and configure E2 in base
setup.

External Setpoint
via external signal (0-10 V, 0-20 mA, 4-20 mA) instead of „Setpoint 1“
The „External Setpoint“ function must be activated in base setup 1E for E2 function; Set Intern 1 then has no function. A
switchover „Ext. Setpoint“ / „Set Intern 2“ is still possible.
