1005 Self acknowledge wire break 2 Yes The control automatically clears the
alarm if the fault condition is no
longer detected.
[No] The control does not automatically
reset the alarm when the fault
condition is no longer detected. The
alarm must be acknowledged and
reset by manually pressing the
appropriate buttons or by activating
the LogicsManager output "External
acknowledgement" (via a discrete
input or via an interface).
Notes
This parameter is only visible if wire
break monitoring (parameter 1003) is
not set to "O󰈠"
10113 Filter time constant 2 O󰈠, 1 to 5 A low pass 󰈡lter may be used to
reduce the 󰈢uctuation of an analog
input reading. The 󰈡lter time constant
assesses the average of the signal
according to the following formula:
• Cut-o󰈠-frequency = 1 / (20 ms *
2 * π * 2
N - 1
)
whereby "N" is the 󰈡lter time constant
and the cut-o󰈠-frequency is de󰈡ned as
usual with 63% (e
-1
).
O󰈠 The analog input is displayed without
󰈡ltering.
1 Cut-o󰈠-frequency = 7.96 Hz (󰈡lter
time constant = 0.02 s)
2 Cut-o󰈠-frequency = 3.98 Hz (󰈡lter
time constant = 0.04 s)
[3] Cut-o󰈠-frequency = 1.99 Hz (󰈡lter
time constant = 0.08 s)
4 Cut-o󰈠-frequency = 0.99 Hz (󰈡lter
time constant = 0.16 s)
5 Cut-o󰈠-frequency = 0.50 Hz (󰈡lter
time constant = 0.32 s)
