Supervision of binary IO module#2 (BIO#2 error)
A supervision function is provided to detect the operation failure in the second binary IO
modules (BIO)†.
†Note: The function can operate for respective BIO modules mounted in the IED; the user
should have settings in them, which are located at the IO slot identified with the
number.
(i)
Error level
Generally, the default error level has been set at level 1 (
Serious error 1
). For example, the user
can program the level using setting [
CHK_BIO2:LVl
] when the BIO module at the IO#2
2
slot
should be supervised; then, set
On
for the setting [
CHK_BIO2:Sw
]. The manufacturer sets one
(1) second to detect the failure; it is reset within a second when the failure is cleared.
1
Note: When the error is detected, the entire operation of the IED is stopped forcibly.
2
Note: The location of the IO slot is discussed in Chapter
Technical description: IED case
and module slot.
(ii)
Error message
When detecting an error, an error message can be shown on the LCD screen and an LED is lit.
