IFM Electronic efector 500 PB5 Notice Utilisateurs page 13

Avoid static and dynamic overpressure exceeding the given over-
load pressure.
Even if the bursting pressure is exceeded only for a short time
the unit can be destroyed (danger of injuries)!
Indication of the current system pressure as from 5% of the
value of the measuring range. "All LEDs OUT" does not mean
that the system is free of pressure!
The unit
• can be used as N.O. or N.C.
• and operates with the hysteresis function.
When the system pressure is
rising, the output switches when
the switch-on point has been
reached (S); when the system
pressure is falling again, the out-
put switches back when the
switch-off point (R) has been
reached.
The hysteresis can be set: First
the switch-on point is set, then
the switch-off point with the
requested difference.
Setting range:
Order no.
