17.4.6 Operation principle
Put the IED into test mode to test functions in the IED. Set the IED in test mode by
• configuration, activating the input SIGNAL on the function block TESTMODE.
• setting TestMode to On in the local HMI, under Main menu/Tests/IED test
mode/1:TESTMODE.
While the IED is in test mode, the output ACTIVE of the function block TESTMODE
is activated. The outputs of the function block TESTMODE shows the cause of the
“Test mode: being in On” state. If the input from the configuration (OUTPUT signal
is activated) or setting from local HMI (SETTING signal is activated).
While the IED is in test mode, the yellow START LED will flash and all functions are
blocked. Any function can be unblocked individually regarding functionality and
event signalling.
Forcing of binary output signals is only possible when the IED is in test mode.
Most of the functions in the IED can individually be blocked by means of settings from
the local HMI. To enable these blockings the IED must be set in test mode (output
ACTIVE is activated). When leaving the test mode, and returning to normal operation,
these blockings are disabled and everything is set back to normal operation. All testing
will be done with actually set and configured parameter values within the IED. No
settings will be changed, thus no mistakes are possible.
