Gefran controller: Can I change the retransmission analogue output to a control output on a 600-x-x-W-x-x?

Yes, the 'W' output card can be used for retransmission or control. For retransmission set An.o = 0 , for control set An.o = 5 or 6.

Gefran controller: How can I retransmit the PV to a PLC with 4-20mA on a 600-x-x-W-x-x?

The standard retransmission setting is 0-10V, but can be changed to 2-10V/ 0-20mA or 4-20mA.

Gefran controller: Can the analog output on a 600-x-x-C-x-x be converted from 0-10V to 4-20mA?

Yes, although 0-10V is the standard output, the analogue signal can be changed to 4-20mA.

Gefran controller: Can the analog output on a 600-x-x-C-x-x be converted from 0-10V to 2-10V?

Yes, although 0-10V is the standard output, the analogue signal can be changed to 2-10V.

Gefran controllers: The top display is showing Hi or Lo. What does this mean?

This is usually an indication that the sensor signal is out of the configured range. Check that the input range is within tolerance:

Gefran controller: The top display is showing Err. What does this mean?

This usually an indication of a) a faulty Pt100 or analogue signal or b) wrong sensor type or c) sensor signal is out of range or d) incorrect/damaged input connection.

Gefran controller: The top display is showing Sbr. What does this mean?

This is usually an indication of a faulty thermocouple temperature sensor (open circuit or faulty cable).
