Pendants used inside safeguarded space must be equipped with an enabling switch or function.

• A. False
• B. True
• C. Only in manual mode
• D. Only with dual-hand control

Answer: (B)

When a pendant is located inside a safeguarded space, there must be an explicit action required from the operator to enable motion. This enabling switch or enabling function ensures that movement isn’t started or continued accidentally if the operator’s hand slips, a fault occurs, or the system is transitioning between states. The idea is to keep the operator in control for every potentially hazardous operation, so the machine will only move when the operator actively enables it—such as with a dead-man style switch, a hold-to-run button, or a dedicated enabling function integrated into the pendant.

This protection is not limited to a single mode like manual operation, and while dual-hand controls are one valid form of enabling, they are not the only option. The essential point is that some enabling mechanism is present on the pendant inside the safeguarded space to confirm deliberate operator involvement before motion occurs.

So, pendants inside safeguarded spaces must be equipped with an enabling switch or function.
