5.1.7
Output "Program selection active"
Indicates that the program selection was activated. This signal is not set, if the program is selected
via the control panel.
5.1.8
Output "Ready for measuring"
Indicates that the control unit is ready for a measurement, i.e. that a measurement can be started.
This is the case if the program -/operating mode is "automatic/ready". In the operating mode
"setup / edit" the signal is set only if the keys <test job start>, <drive> or in the X/Y function the key
<start> were confirmed.
5.1.9
Output "Set-up active"
This output is set only in the "setup / edit" mode as soon as the keys
<test job start>, <drive> (or in the function X/Y the key <start>) have been confirmed.
When the SND40 was configured to "Control test job: PLC", a signal is sent to the PLC for
preparing a tube for detection.
When the SND40 was configured to "Control test job: KM", a signal is sent to the PLC for set-up
operation.
5.1.10 Output "Slippage/weld seam detected (duration)"
The output OUT4 "Weld seam detected (permanent) is only activated in the system configuration at
acknowledge mode.
Meaning in the "round specimen" mode: "slippage".
During the measurement slippage was detected.
Meaning in the "flat specimen" mode: "weld seam detected (duration)".
A weld seam was detected, but not yet acknowledged. This takes place via the input "weld seam
acknowledge".
5.1.11 Output "General fault"
In the "round specimen" mode this output is set, if either "slippage", "critical detection" or a fault are
to be displayed.
In the "flat specimen" mode this output is set, if a fault is to be displayed.
5.1.12 Output "Reduced detection capability"
In the "round specimen" mode this output is set, if "critical detection" is to be displayed.
In the "flat specimen" mode this output is not used.
5.1.13 Output "Motor / weld seam detected (impulse)"
In the "round specimen" mode this output is used for the control of the rotary drive/motor. The
output is set, as long as the tube is to be rotated.
In the "flat specimen" mode this output is used for reporting of the weld seam detected. The signal
is set as long as a weld seam is detected. This time can be extended via the "switch-off delay"
parameter (50 ms and 200 mc only)
5.2
Output „Ready" via Fieldbus
Output via Fieldbus only. Only set when unit started up without faults.
4
The pulse length can be adjusted with the parameter "switch-off delay".
