6-142 Modular Block System: Hydraulic Presses
Standard Function Blocks
WARNING!
If the time values entered for TOn and TOff are too long, serious injuries
could result should the danger zone be accessed during operation.
The reaction time of the safety valve determines the stopping time of the
press on an emergency stop. The stopping time determines the safety
distance to the tool.
Reaction times should be included in the calculation of the safety
distance if the time values set for the parameters
TOn and TOff are
significantly higher than the actual valve reaction times.
• Please note:
- With directional control valves (input parameter VTyp = 0), the reaction
time when the valve switches on and off must always be monitored
(see under “Settings for the parameters
TOn and TOff”).
- With poppet valves, the reaction time when the valve switches on and
off may be monitored (see under “Settings for the parameters TOn and
TOff”).
