9.1. Test the actual set value defined by SpChAlmTime.
9.2. Enable SPRCHRST input. Also activate SPRCHRD after a time greater
than set time SpChAlmTime.
9.3. At this condition, SPCHALM is activated.
10. Test of CB gas pressure indication
10.1. Test the actual set value defined bytDGasPresAlm and tDGasPresLO.
10.2. The output GPRESALM is activated after a time greater than set time of
tDGasPresAlm value if the input PRESALM is enabled.
10.3. The output GPRESLO is activated after a set time of tDGasPresLO value
if the input PRESLO is enabled.
10.12.3.2 Completing the test
GUID-0A16206F-690E-46EF-86F4-5A89E0BF640B v3
1. Continue to test another function or end the test by changing the Test mode
setting to Off.
2. Restore connections and settings to their original values if they were changed
for testing purposes.
10.12.4 Event function EVENT
M11751-2 v5
Prepare the IED for verification of settings as outlined in section "Preparing for
test" in this chapter.
During testing, the IED can be set when in test mode from PST. The functionality
of the event reporting during test mode is set in the Parameter Setting tool in
PCM600.
• Use event masks
• Report no events
• Report all events
In test mode, individual event blocks can be blocked from PCM600.
10.12.5 Limit counter L4UFCNT
GUID-7EBDC372-3407-4577-8B9A-6AB1758A1F34 v2
The Limit counter function L4UFCNT can be tested by connecting a binary input
to the counter and applying pulses to the counter. The speed of the pulses must not
exceed the cycle time of the function. Normally the counter will be tested when
testing the function that the counter is connected to, such as the trip function. When
the function is configured, test it together with the function that operates it. Trigger
the function and check that the counter result corresponds to the number of
operations.
