Device-specific Safety Instructions
Table 3- 3
Proof test part 3 (only required if external sensors are used)
Step
Action
1
Bypass the safety PLC or take another appropriate action to avoid a false trip.
2
Select analog input test for Analog Temperature using LUI (local user interface).
3
Connect a calibrated current source, e.g. a loop calibrator, to the analog input 0 for temperature.
Note: the current measuring instrument used for this test shall provide an accuracy of 0.1 % or better.
4
Apply at least the following currents in succession: 4.0 mA, 20.0 mA, and a current value within this
interval to the analog input. The indicated measured values [mA] shall not deviate more than 0.5 % from
the applied current.
5
Select analog input test for Analog Pressure using LUI.
6
Connect a calibrated current source, e.g. a loop calibrator to the analog input 1 for pressure.
Note: the current measuring instrument used for this test shall provide an accuracy of 0.1 % or better.
7
Apply at least the following currents in succession: 4.0 mA, 20.0 mA, and a current value within this
interval to the analog input. The indicated measured values [mA] shall not deviate more than 0.5 % from
the applied current.
8
Restore the loop to full operation.
9
Remove the bypass from the safety PLC and restore to normal operation.
Table 3- 4
Step
Proof test part 4
Action
1
Bypass the safety PLC or take another appropriate action to avoid a false trip.
2
Unlock the LUI using the service password (Security menu).
3
Select analog output test / analog output 0 using LUI.
4
Connect a calibrated current measuring instrument with loop powering capability, e.g. a loop calibrator, to
the analog output 0.
Note: the current measuring instrument used for this test shall provide an accuracy of 0.1 % or better.
5
Set at least the following currents in succession: 4.0 mA, 20.0 mA, and a current value within this interval
to the analog output. The measured current shall not deviate more than 0.5 % from the set current.
6
Select analog output test / analog output 1 using LUI.
7
Connect a calibrated current measuring instrument with loop powering capability, e.g. a loop calibrator, to
the analog output 1.
Note: the current measuring instrument used for this test shall provide an accuracy of 0.1 % or better.
8
Set at least the following currents in succession: 4.0 mA, 20.0 mA, and a current value within this interval
to the analog output. The measured current shall not deviate more than 0.5 % from the set current.
9
Restore the loop to full operation.
10
Remove the bypass from the safety PLC and restore to normal operation.
