15.4.6 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 Enabled 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 other outputs of the function block TESTMODE shows the cause of the
"Test mode: Enabled" state — input from configuration (OUTPUT signal is activated) or
setting from local HMI (SETTING signal is activated).
While the IED is in test mode, the yellow PICKUP 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.
The blocked functions will still be blocked next time entering the test mode, if the
blockings were not reset. The released function will return to blocked state if test mode is
set to off.
The blocking of a function concerns all output signals from the actual function, so no
outputs will be activated.
