failure.
UVS trip signal
(ii)
The UVS1 element issues a trip command for the trip circuit (TRC†) when Trip is set for scheme
switch [UVS1-UseFor] as the normal tripping. However, when an alarm signal in place of the
trip command is required, the user can set Alarm for the scheme switch [UVS1-UseFor].
†Note: For more information about tripping, see Chapter 2.23.
Operation of UVS function
(iii)
Set On for scheme switch [UVS1-EN]. Otherwise, set Off for the scheme switch [UVS1-EN] if
the UVS1 element is not required to operate.
Under voltage test
(iv)
Setting [UVS-Test] =On is not to operate UVS blocking element (UVSBLK) for testing.
Scheme logic
2.14.4
Figure 2.14-4 show the logic of the UVS function. PLC connection points "UVS1_BLOCK" is
provided for blocking the operation of the UVS1 element. Other PLC connection points
"CB_APH_OPEN" etc. are provided so that the UVS1 function can determine its operation
using the open/closed information of a circuit breaker (CB). For testing, the UVS1-PU element
is provided; it generates a pick-up signal when the entering voltage is below the threshold
anytime. For example, in the IDMT characteristic, using both PLC monitoring points
"8000011B20" and "8000011B24" can facilitate to measure the pickup time after the deficiency.
