Supervision of binary IO module#4 (BIO#4 error)
A supervision function is provided to detect the operation failure in the forth 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 error level has been set at level 1 (
Serious error 1
), as default. For example, the
user can program the level using setting [
CHK_BIO4:LVl
] when the BIO module at the IO#4
2
slot should be supervised; then, set
On
for the setting [
CHK_BIO4:Sw
]. The manufacture sets
one (1) second to detect the failure; it is reset in a second when the failure is cleared.
1
Note: The entire operation of the IED is stopped forcibly when the error is detected.
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.
