NOTE

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

NOTE

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.I10] is equal to “ñC.On” or “ñC.OF” or “SC.On” or
“SC.OF”.
Range: from 0 to "Fd.HS" [C.I12].
NOTES

NOTES

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.I10] is equal to “ñC.On” or “ñC.OF” or “SC.On” or
“SC.OF”.
Range: from 0 to "Fd.HS" [C.I12].
NOTES

NOTES

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.
