Modular Block System: Hydraulic Presses 6-137
INFORMATION
If valves Y1 and Y2 are acknowledged via switches, the supply to these
switches must be from test pulses.
If valves Y1 and Y2 are acknowledged via proximity switches which
cannot be pulsed, the signal lines of the proximity switches must be laid
in different multicore cables within the duct. This will ensure that a short
cannot occur between the two signal lines.
This safety precaution will not be necessary if you use proximity switches
with diverse signals.
• TOn: Maximum permitted reaction time for switching on both valves
(in ms)
TOn = KF 001 ... KF 350 when VTyp = 0 (directional control
valve)
TOn = KF 000 ... KF 350 when VTyp = 1 (poppet valve)
Ensure you follow the guidelines given under “Safety
guidelines for input parameters
TOn and TOff”
• TOff: Maximum permitted reaction time for switching off both valves
(in ms)
TOff = KF 001 ... KF 350 when VTyp = 0 (directional control
valve)
TOff = KF 000 ... KF 350 when VTyp = 1 (poppet valve)
Ensure you follow the guidelines given under “Safety
guidelines for input parameters
TOn and TOff”
• Y1On: Operate valve for overrun measurement
Y1On = 0: Switch off valve Y1 for external overrun
measurement
Y1On = 1: Enable valve Y1
In normal operation, Y1On should be assigned
RLO-1 (M110.01).
(see also under “Function”)
• Y2On: Operate valve for overrun measurement
Y2On = 0: Switch off valve Y2 for external overrun
measurement
Y2On = 1: Enable valve Y2
In normal operation, Y2On should be assigned
RLO-1 (M110.01).
