Connecting the pendant

About this topic

This topic describes how to connect the emergency-stop pendant to the BenchCel Microplate Handler.

Before you start

The safety interlock circuit must be closed for the device to operate. The way you connect the pendant depends on the type of devices that you are integrating:

•	If the integrated devices are not equipped with safety interlock circuitry, connect the pendant directly to the BenchCel device.

•	If the integrated devices are equipped with safety interlock circuitry, such as the Bravo Platform, connect the pendants through a main emergency stop button, such as the Robot Disable Hub. See About integrating the Robot Disable Hub and pendant.

Connecting the pendant directly to the BenchCel device

Use the following procedure if you are integrating the BenchCel Microplate Handler with devices that are not equipped with safety interlock circuitry, for example, the PlateLoc Sealer or the Microplate Labeler.

To connect the pendant directly to the BenchCel device:

Connect the pendant cable to the pendant port on the back of the BenchCel device.

 

About integrating the Robot Disable Hub and pendant

The Robot Disable Hub connects the safety interlock circuits of the BenchCel Microplate Handler and integrated devices. The Robot Disable Hub does the following:

•	Provides the emergency-stop function for the BenchCel robot and up to five integrated devices that are equipped with safety interlock circuitry.

•	Receives interlock-circuit signals from a light curtain, if connected.

Figure. Robot Disable Hub

 

Pressing the red button on a pendant connected to the safety interlock circuit through the Robot Disable Hub will trip the interlock circuit, causing all the devices on the circuit to stop.

The Robot Disable Hub has two rows of connectors:

•	PENDANTS. Accommodates the BenchCel pendant and up to five additional pendants.

IMPORTANT Any unused PENDANTS connectors require E-stop jumpers to close the interlock circuit.

•	DEVICES. Accommodates the BenchCel device and up to five other devices with interlock circuits.

The following figure shows an example of connecting the BenchCel device and the Bravo Platform through the Robot Disable Hub.
