Terminal name
The input terminals for power supply. Connect the power source to the A1 and A2 terminals.
DC inputs have polarity, so A1 should be connected to the positive side and A2 to the negative side.
To set the safety outputs in the ON state, the ON state signals must be input to both safety input 1 and
safety input 2. Otherwise the safety outputs cannot be in the ON state.
To set the safety outputs in the ON state, the ON state signal must be input to T31 - T32. Otherwise the
safety outputs cannot be in the ON state.
Turns ON/OFF according to the state of the safety inputs and feedback/reset inputs. During OFF-delay
state, the Instantaneous safety outputs are not able to turn ON.
OFF-delayed safety outputs. The OFF-delay time is set by the OFF-delay preset switch.
Synchronized with Instantaneous Safety Output.
Switch between Auto Reset and Manual Reset modes.
Be sure to connect the PE terminal to a protective earth for 100-240 VAC models.
Where the 24 VAC/VDC model power supply is not grounded, lease be sure to connect the PE to a
protective earth.
