DMC3S - Manual - 08 - 2021
— Average measures
The average measures (Demand) are calculated as follows:
Fixed mean
I
L1FIX
,
I
L2FIX
,
I
L3FIX
Arithmetic mean of the values I
L1
,
I
L2
,
I
L3
acquired every 1 s, over a time period t
FIX
, from 1 to 60 min-
utes, updated at the end of the period itself.
The mean can be reset with the keypad, with the command Reset average measures (in the menu
Commands Thysetter), or via a logical input. The parameter tFIX is in the menu Set \ Average meas-
ures.
Mobile mean
I
L1ROL
,
I
L2ROL
,
I
L3ROL
The arithmetic mean, in a mobile window of N.Rol * tROL, of the values I
L1
,
I
L2
,
I
L3
acquired every
1 s, where T is the length of each subinterval of time tROL, from 1 to 60 minutes, and N.Rol is the
number of subintervals of time (from 1 to 24), updated at the end of each subinterval. The mean can
be reset with the keypad, with the command Reset average measures (in the menu Commands Thy-
setter), or via a logical input.
The parameters tROL and N.Rol are in the menu Set \ Average measures.
Maximum
I
L1MAX
,
I
L2MAX
,
I
L3MAX
Maximum value of the arithmetic mean of the values I
L1
,
I
L2
,
I
L3
acquired every 1 s, over a window
equal to the time subinterval tROL (setting shared with Mobile mean), updated at the end of the
subinterval itself.
The mean can be reset with the keypad, with the command Reset average measures (in the menu
Commands Thysetter), or via a logical input.
tROL is the same parameter as that used for the Mobile mean.
Minimum
I
L1MIN
,
I
L2MIN
,
I
L3MIN
Minimum value of the arithmetic mean of the values I
L1
,
I
L2
,
I
L3
acquired every 1 s, over a window
equal to the time subinterval tROL (setting shared with Mobile mean), updated at the end of the
subinterval itself.
The mean can be reset with the keypad, with the command Reset average measures (in the menu
Commands Thysetter), or via a logical input.
tROL is the same parameter as that used for the Mobile mean.

Set trigger
The following parameters in the menu Oscillography \ Set trigger are user programmable:
• Pre-trigger time and Post-trigger time.
• When the parameter Enable triggers with outputs is set to ON, registration starts when any
protection threshold changes state.
• When the parameter Trigger with outputs is set to ON , registration starts when one or more
outputs selected in the menu trigger with outputs (51AP, 52CH, 80S, KS1-1...6) and trigger
with DMRIS0 control outputs (OUTD1-1, OUTD1-2, OUTD2-1, OUTD2-2) change status.
• When the parameter Enable triggers with inputs is set to ON, registration starts when any
logical input selected in the menu changes state.
- Trigger with inputs (IN1-1...IN1-6, INC-1...INC-5)
- Trigger with DMRIS01 inputs (IND1-1...IND1-12)
- Trigger with DMRIS02 inputs (IND2-1...IND2-12)
• Filling 80% of memory will generate an alarm if the parameter 80% buer alarm is set to ON.

selected in the menu Set \ Oscillography \ Set measurement channels.
Each of the twelve measurement channels can be mapped to a measurement.
Set digital channels
The I/O signals (52AP, 52CH, 80S, TripMV, KS1-1... KS1-6, KC2-1...KC2-8, KS1-1... KS1-6, IN1-1... IN1-6,
INC-1... INC-5) to be registered cxan be selected in the menu Set \ Oscillography \ Set digital chan-
nels.
Set DMRIS0 digital channels
The I/O signals related to the first external DMRIS0 module (IND1-1...IND1-12, OUT1-1, OUT1-2) and
second external DMRIS0 module (IND2-1...IND2-12, OUT2-1, OUT2-2) to be registered can be se-
lected in the menu Set \ Oscillography \ Set digital channels and Set \ Oscillography \ Set DMRIS0
digital channels.
Each of the sixteen digital channels can be mapped to an I/O signal.
