7 Disposal
The customer/enduser is obliged to take care for the disposal within the legal regulations.
8 Trouble shooting
Failure Problems Correction
no function wrong wiring, fuses, current supply check it
no bistable behaviour wrong mounting of the housing rise distance
the switch is always closed
(740.0060)
power switch: low current
Mini-switch: supply voltage > 24V
use it as a mini-switch
remove resistor R1
the switch opens spontane-
ously (miniswitch)
load is too high
temperature is too high
use an isolating switch amplifier
use a heat protection plate
