Technical Data of Switching Elements of Enabling Switches
Nominal voltage 24 V DC (typ.)
32 V DC (max.)
Nominal current 500 mA (typ.)
Short-circuit current circuit 1: max. 1,9 A
circuit 2: max. 600 mA
Max. inductive load (at 500 mA) circuit 1: max. 1H
circuit 2: max. 320 mH
Max. capacitive load circuit 1: no limit since the transistor is protected thermally
circuit 2: max. 500 µF
The switching elements of the enabling switches are protected against re-
versed polarity. The outputs of both circuits are protected against short cir-
cuits and excess load.
Circuit 1: thermal protective circuit
Circuit 2: fold back line
WARNING
!
• The enabling switch is only suitable as safety function if the operator activating
the enabling switch recognizes the dangerous situation in time so that he can
immediately take the necessary measures to avoid such situations.
As additional measure reduced speed of the movement can be necessary. The
allowed speed must be determined by means of a risk assessment.
• The enabling switch is only used to enable commands for performing dangerous
movements. The commands themselves must be activated by a separate oper-
ating element (key on handheld terminal).
• Only the person who operates the enabling switch is allowed to work in the dan-
gerous area.
• For further informations regarding the enabling switch please pay attention to
chapter „
CE Conformity, Directives and Standards“.
