Figure7. 36 Wiring Example Of A Single Emergency Stop Button - Delta SCARA DRS40L Series User Manual

Delta SCARA Robot System User Manual
Connects to external emergency stop notes:
 The emergency stop is a dry contact (voltage-free contact) signal. Do not connect AC or DC
voltage signal, or it may cause the damage to the internal components of the controller.
 Short-circuiting the emergency stop signal is strictly prohibited; this ensures the safety of the
overall robot system and workers.
 Emergency stop is a safety signal; please install the emergency stop button at a location that can
be easily pressed.
 Please distribute the power properly according to the methods described in the wiring diagram. The
emergency stop button must have 2NC contact. If only 1 NC contact is connected, the power
control box will have emergency stop abnormalities continuously.
 Please do not connect one 1NC contact to Pin1~Pin4 of the safety connector simultaneously; this
will cause the safety level of the system to decrease.
 Please construct according to the entire actual equipment and install one or more emergency stop
buttons. When multiple emergency stops need to be connected, please use serial connection for
the emergency stop NC signal; parallel connections cannot be used.
 When the emergency stop signal is triggered, the robot will stop immediately and the AC power will
be cut in order to reach type 0 safety stop.
