Figure 71: Testing mA output by connecting multimeter directly to
connector and measuring output current by multimeter
• Check the status of the output circuits driving the mA outputs via the LHMI.
Select Main menu/Monitoring/I/O status/mA output modules/RTD3 and
check the output status and value for the channel under inspection.
• Test and change the output manually.
1. Select Main menu/Test/IED test mode/TestMode and set the parameter
to "On".
2. Select Main menu/Tests/Forcing/Analog output values/RTD3.
3. Select the AOn to be forced.
4.
Force the actual output using
Each AOn is represented by two signals. The first signal in LHMI is the actual
primary value of the output. The second signal is the status Normal or Forced.
Forced status is only achieved when the AO is set to "Forced" on the LHMI.
When forcing analog output signals the scaling defined by analog
output channel configuration is not used. Fixed scaling factor
1000:1 is used instead. This means that forcing value 5.000 A is
seen as 5 mA when measured from output.
Do not force or send values to disconnected channels. This results
in an out-of-range error.
Forcing feature can be tested only for configured output channels.
When mA current values are forced to non-configured output
channels, values are not passed to mA output channel HW
circuitry.
