IRIG‑B Commissioning
Activate the IRIG‑B synchronization within the menu [Device Para / Time / TimeSync]:
• Select »IRIG‑B« in the time synchronization menu.
• Set the time synchronization in the [IRIG-B] menu to “Active”.
• Select the IRIG‑B type (choose B000 through B007).
Fault Analysis
If the device does not receive any IRIG‑B time code for more than 60 s, the IRIG‑B status
switches from »active« to »inactive« and there is created an entry within the Event
Recorder.
Check the IRIG‑B functionality through the menu [Operation / Status Display / TimeSync /
IRIG-B]:
Should the IRIG‑B status not be reported as being “Active”, please proceed as follows:
• To begin with check the IRIG‑B wiring.
• Check, if the correct IRIG‑B00X type is configured.
IRIG‑B Control Commands
In addition to the date and time information, the IRIG‑B code offers the option to transmit
up to 18 control commands that can be processed by the protective device. They have to
be set and issued by the IRIG‑B code generator.
The EMR-3MP0 offers up to 18 IRIG-B assignment options for those control commands in
order to carry out the assigned action. As soon as a control command is transmitted the
state of the corresponding signal »IRIG-B . Control Signal1« … »IRIG-B . Control
Signal18« becomes true.
These signals are available for assignment to some parameter, so that the functionality of
this parameter is being triggered as soon as the control command is transmitted.
NOTICE!
IRIG‑B control commands are not recorded by Event and Waveform Recorders.
If it is required to have a control signal recorded, the best way is to use a Logic (1 gate)
equation, because the Programmable Logic always gets recorded.
