WARNING: Do not use switches in the E-Stop circuit that do not comply
with Category 1 requirements.
See Table 3-1 for the terminal assignments of the terminal block on the external Front
Panel for the monitoring of the Emergency Stop switches on the Manual Control Pendant
and the external Front Panel, and the Hold-to-Run button on the MCP.
Terminal Block on External Front Panel
Adept provides voltage-free contacts on the terminal block on the back of the external
Front Panel for monitoring the emergency circuitry components and other switches. It is a
vital part of your safety system. The user has access to the voltage-free contacts of the
Emergency Stop switches on the Manual Control Pendant and the external Front Panel.
Additionally, there are contacts for monitoring the Hold-to-Run switch on the MCP and
the position of the System Power and Operating Mode switch on the external Front Panel.
See Table 3-1 for assignment of the terminals.
The voltage-free contacts can be used to create additional safety circuitry or to monitor the
existing one. For instance, the user can control additional contactors with the voltage-free
contacts that turn on and off the power supply to the PA-4 power chassis. Then it is
possible to enable High Power to the motors of the module only if the E-Stop circuitry is
closed. See Figure 3-3 for an example of additional safety equipment that uses the
voltage-free contacts on the external Front Panel and the external E-Stop Inputs on the SIO
Module in the Adept MV Controller.
