Operating Instructions
Key switch Test Release
•
On the front side
•
Used for enabling/disabling test
•
OFF: test release withdrawn (output contactors and power
stage are blocked)
•
ON: test release given, test may be started (e.g. acknowl-
edged by software)
Service switch/circuit breaker for motor protection
•
Behind the front panel (detachable)
•
Fuse for the circuit (logic path) tapped upstream of the main
switch
•
O OFF:
Circuit breaker has triggered → system is inactive; all
power and communication connections (logic path) are inac-
tive.
•
I ON: Logic path active, system can be activated via main
switch
Surge protection
•
Inside the Input Box on the rear side
•
Responds in the event of overvoltage (e. g. due to lightning)
•
Reaction: Feedback signal is detected
→ undervoltage moni-
toring reacts →
the main switch cannot be activated (falls
back to position Trip)
•
Consequence: Surge protection inlets must be changed by
KeysightCare, feedback contact is reset
Safety relay
•
Inside the system
•
Responds when the local emergency stop switch or external
input are triggered via the higher-level safety device (2-pin
each)
•
AC supply of the power stages is interrupted, undervoltage
monitoring triggers, main switch on “Trip” → system is
switched off; power stage enable is withdrawn; 230 V auxil-
iary voltage and 24 V control voltage are maintained (logic
path)
Housing ground/functional earth
•
On the rear side of the system
•
Connection and coupling of housing ground
•
Connection for EMC-compliant design
Display Soft Front Panel power stage
•
On the front side
•
Display is activated when power stage is active/in operation
•
No settings needed
