Max. inductive load (at 500 mA)
Max. capacitive load
The switching elements of the enabling switches are protected against reversed
polarity. The outputs of both circuits are protected against short circuits and excess
load.
• Circuit 1: thermal protective circuit
• Circuit 2: fold back protective circuit
Foreseeable Misuse of Enabling Switch
Foreseeable misuse means not allowing the enabling switch to be fixed in the
enabling position. The foreseeable misuse of the enabling switch must be restricted.
The following measures are recommended, which cause the machine to stop in
manual mode.
• Inquiry of the enabling switch when turning on the machine/plant and
inquiry of the enabling switch when changing the operating mode from
automatic to manual. (The enabling switch must not be in the enabling
position.)
• The enabling switch must be released within a defined period of time and
pushed into the enabling position again. The length of time must be defined
according to the activity.
