Scienlab Regenerative AC Emulator – SL1200A Series – 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• OFF: test release withdrawn (output contactors and power stage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. acknowledged
by software)
Circuit breaker for motor protection (=EIN-1Q2)
• 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 inactive.
• I ON: Logic path active, system can be activated via main switch
Fuses
• Behind the front panel (detachable)
• Fuses for:
• =CV2-1F1: 24 V control voltage
• =CV3-1F1: 12 V Ethernet switch
• =RPS1/3/5-1F1: power stages 1, 3 and 5
• =RPS2/4/6-1F1: power stages 2, 4 and 6 (only for SL1203A
and SL1213A systems)
• Inside the Output Box on the rear side of the system
• Fuses for:
• =ACO-2F1: AC Sense L1'
• =ACO-2F2: AC Sense L2'
• =ACO-2F3: AC Sense L3'
• =ACO-2F4: AC Sense N'
• =DCO-2F1: DC+ Sense (optional)
• =DCO-2F2: DC- Sense (optional)
Surge protection (=EIN-1F1)
• 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
monitoring 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
