5.2.6 Safety Connector

The DCV controller includes a connector for eight-point safety signals. You use these eight-point safety
signals to construct comprehensive robot safety protection. Figure 5.15 shows the location of the safety
connector.
Table 5.2 lists the safety pin definitions.

Notes for connecting the external emergency stop:
 The emergency stop is a dry contact (voltage-free contact) signal. Do not connect an AC or DC
voltage signal to the DCV controller to prevent damage to the DCV controller internal components.
 Short-circuiting the emergency stop signal is strictly prohibited. This ensures the safety of the overall
robot system and the workers.
 The emergency stop is a safety signal. Install the Emergency Stop button in a location that can be
easily reached.
 Properly wire the emergency stop signal according to the methods described in the wiring diagram.
The Emergency Stop button must have 2NC contacts. If only one 1NC contact is connected, the
DCV controller will have continuous emergency stop errors.
 Do not connect one 1NC contact to Pins1–4 of the safety connector simultaneously to prevent
decreasing the safety level of the system.
 Construct the emergency stop system according to the actual equipment and install one or more
Emergency Stop buttons. When connecting multiple emergency stops, use serial connection for the
emergency stop NC signal. Do not use parallel connections.
 When the emergency stop signal is triggered, the robot stops immediately and the AC power is cut
to reach type 0 safety stop.
