Gr. 3
NOTE: The span limits are configured by “ñ.In.L” [C.d05] and
“ñ.In.H” [C.d06].
- Low threshold used when the alarm 4 is a
band alarm - [r.C12]
This parameter is available only when the alarm 4 is configured
as band alarm (“A4.tP” [rF.13] = “bAnd”)
Range: from 0 to -1000 digits.
- high threshold used when the alarm 4 is a
band alarm - [r.C13]
This parameter is available only when the alarm 4 is configured
as band alarm (“A4.tP” [rF.13] = “bAnd”)
Range: from 0 to 1000 digits.
NOTE: The "bA4.L" and "bA4.h" values are algebraically added
to the operative set point in order to obtain the band limits.
- Output failure detection low alarm threshold -
[r.C14]
This parameter is available only when the option is present and
“Fd.Fn” [C.I11] is different from "nOnE".
Range: from 0 to "Fd.HS" [C.I12].
NOTES:
1) The device is in alarm status when the current, measured
during the ON status of the load, is lower than this threshold.
2) The OFD (output failure detection) alarm threshold resolution
values is equal to 0.1 A for range up to 25 A and 1 A for
range up to 100 A
3) The hysteresis on this threshold values is fixed to 1% of fsv.
- Output failure detection high alarm threshold
- [r.C15]
This parameter is available only when the option is present and
“Fd.Fn” [C.I11] is different from "nOnE".
Range: from 0 to "Fd.HS" [C.I12].
NOTES:
1) The device is in alarm status when the current, measured
during the OFF status of the load (leakage current), is higher
than this threshold.
2) The OFD (output failure detection) alarm threshold resolution
values is equal to 0.1 A for range up to 25 A and 1 A for
range up to 100 A
3) The hysteresis on this threshold values is fixed to 1% of fsv
