HR1S-ATE Wiring Diagram
Safety Category 4 (3) Circuit
•
(using an emergency stop switch)
(Note)
Safety
•
Category 3 Circuit (using multiple emergency stop switches)
Emergency stop switch - Input 2 channels
•
When not detecting short-circuit
(B1-S12 short-circuit not detected)
Emergency stop switch - Input 1 channel
•
When not detecting short-circuit (All failures such as short-
circuit of emergency stop switch wiring not detected)
When monitoring the start switch
•
(Y3-Y5 short-circuited)
When not monitoring the start switch
•
(Y3-Y4 short-circuited)
(automatic start when S33-Y2 is short-circuited)

When monitoring the start switch, starts when switched off (default setting/recommended)
When monitoring the start switch, starts when switched on
Outputs must be fused (see the instruction manual for maximum fuse size)
To PLC, etc.
Note: When using off-delay output, safety category becomes 3.
S1 = Emergency stop switch with 2 NC contacts (recommended)
S2 = Start switch
ESC = External start conditions
