4-6
Intended Use
Modular Block System: Hydraulic Presses
Operating modes:
• Automatic start when PSS starts up or when starting I/O-Groups
(SafetyBUS p)/start-up reset when PSS is cold-started or when starting
I/O-Groups (SafetyBUS p) (start-up disabler)
• No function test/function test on the gate during start-up
(function test = opening and closing the gate)
• Automatic restart/reset to start (reset lock)
• Restart without function test/start only after function test on the gate
(reset lock) (function test = opening and closing the gate)
• Synchronisation time is selectable
INFORMATION
Input circuitry:
• Inputs should have pulsed outputs
SB065: Feedback loop monitoring
SB065 is a standard function block for the direct control and monitoring of
1 or 2 contactors up to category 4, in accordance with EN 954-1, 03/97.
INFORMATION
On SB065, the SSNR may lie in the range of 1 to 600.
Features and application areas:
• Feedback loop is monitored during the change in the switch signal and
while the contactors are in a static condition.
• Feedback loop can be monitored on two separate feedback loops of
contactors connected in series
• Feedback loop can be monitored on two separate feedback loops of
contactors connected in parallel
• Feedback loop can be monitored on group contactors
• Selectable time for feedback loop monitoring
• Parameter to suppress error messages when an I/O-Group stops
