3.1.2
Connector Pin Assignment of Inputs & Outputs
The outputs always represent the last measurement. They will be set or cleared only after
a new measurement.
3.1.2.1
Connector X54 (Outputs)
Pin
Name
Channel
Function
1
Ready
1 and 2
Control unit ready and can receive data. Ready flag skipped
during counter or measured value reset, during boot
procedure, or by HIGH signal at control input NOT READY,
measurement reset, data transfer
2
Current
1
Signal waiting until manually set measuring time ends after
acquired current input or as long as an active current signal
lasts that is registered in the course of the measuring time.
3
WARN min.
1 and 2
Output of prewarning monitoring minimum.
4
WARN max.
1 and 2
Output of prewarning (WARN) monitoring maximum.
5
Limit value
min.
1 and 2
Output of limit value monitoring minimum.
6
Counter limit
1 and 2
Signal waiting when counter final value is reached till counter
reset.
7
REJECT
2
Signal waiting as soon as monitored parameter is outside of
limit value tolerance.
8
Current
2
Signal waiting until manually set measuring time ends after
acquired current input or as long as an active current signal
lasts that is registered in the course of the measuring time.
14
ACCEPT
1
Signal waiting as long as parameters monitored with limit
values are within limit value tolerance.
15
REJECT
1
Signal waiting as soon as monitored parameter is outside of
limit value tolerance.
16
Overflow
1 and 2
Signal waiting if a set measuring range is exceeded by the
measured parameter.
17
Zero current
1
Signal is activated:
a) after external trigger signal if no current is measured during
this.
b) after part detection subsequent to interrupted part
evaluation (valid part detection).
c) if trigger source “0 penetration“ or “Force trigger“ is
activated and no current is measured.
Signal is deactivated:
a) at beginning of measurement
b) with signal at measuring value reset input
18
Limit value
max.
1 and 2
Output of limit value monitoring maximum.
19
Counter
WARN
1 and 2
Signal waiting when counter reached prewarning value till
counter reset.
20
ACCEPT
2
Signal waiting as long as parameters monitored with limit
values are within limit value tolerance.
21
Zero current
2
Signal is activated:
a) after external trigger signal if no current is measured during
this.
b) after part detection subsequent to interrupted part
evaluation (valid part detection).
c) if trigger source “0 penetration“ or “Force trigger“ is
activated and no current is measured.
Signal is deactivated:
a) at beginning of measurement
b) with signal at measuring value reset input
