Connection and Assembly 3
The pin assignment depends on the corresponding system configuration
and can be taken from the corresponding circuit diagram.
Connecting higher-level safety technology
If the system is integrated into an overall test bench with other systems,
the operator should carry out a risk assessment.
Without prior connection to a higher-level safety system, misuse can result in life-
threatening injuries.
Keysight recommend first connecting the system to the higher-level safety and
emergency stop system of the test bench, before putting it into operation.
The Keysight emergency stop system in the control cabinet may not be
changed or adapted without the consent of Keysight.
The SL1200A provides the option to exchange permanently defined exter-
nal signals with the superordinate control and safety computer. The termi-
nals for all safety-relevant input/output signals are located in the output
box on the rear side of the system. The lines to the terminals are routed
via the base plate into the output box.
The signals are the following:
External emergency stop
External release output contactor
The system-specific circuit diagram defines all available incoming and
outgoing signals and the associated terminals.
Connection of external safety signals
•
External test release signal (2-pin)
OFF: test release withdrawn (output contactors and power
stage are blocked)
ON: test release given, test may be started (e.g. acknowledged
by software
• Emergency stop In/Out (2-pin)
• Jumpers have to be removed for connecting external release
or emergency stop in/out.
• Connection via the base plate of the output box according to
circuit diagram
The internal emergency stop chain is designed redundant (2 channels).
The following table shows a short description of each connection terminal:
