Proof Test Procedure C
1. Prepare the test set-up, see figure below.
2. Connect an input load of 1.8 k
to terminals 1- and 4+.
3. Measure the voltage load across the resistor and the current derived from it.
The current value must be between 4.9 mA and 5.7 mA.
4. Disconnect the ancillary equipment.
5. Set back the device to the original settings after the test.
6. Restore the safety loop.
