Circuit diagram for automated reset
In order to configure the logic for the safety system, this must be set with the rotary
switch of the Flexi Classic safety controller.
Program 8 must be selected on the UE410-MU.
Program 3 must be selected for channel A on the UE410-8DI and program 6 for chan‐
nel B.
Q3 and Q4 switch depending on the status of the primary protective device and safety
laser scanner used (channel B).
Q1 and Q2 switch depending on the status of the emergency stop pushbutton (channel
A).
The normally open contacts of the relays at Q3 and Q4 must have a dual-channel con‐
nection to the protective stop input in the robot controller.
For automated reset and EDM, the normally closed contacts must be connected in
series on S2.
The normally open contacts of the relays at Q1 and Q2 must have a dual-channel con‐
nection to the emergency stop input in the robot controller.
For manual reset and EDM, the normally closed contacts must be connected in series
with the reset pushbutton on S1.
