Hazards of the system and robot are isolated by the safety guard . When a worker needs to work inside the hazardous
area for maintenance, the worker stops the machine using the key to change modes (1), unlock the guard using the key,
then remove the key to bring inside the safety guard (2) . The worker can switch operation modes and unlock the safety
guard using a single key . Furthermore, when the key is taken inside the hazardous area, the guard cannot be locked and
the system cannot be turned on . This enables the worker to work safely in the hazardous area .

Head removal detection circuitry is employed in the HS5E-K . With this innovative function, the monitor circuit (41-42) turns off
when the head is removed from the switch, such as when removing the head to change the head direction (applicable with all
models of HS5E-K) .
With the head installed on the switch, monitor circuits 41-42 and 51-52 operate in synchronization while the key locks/unlocks
the actuator . When the head is removed, 41-42 turns off and 51-52 turns on . This disagreement is detected by the head removal
detection function .
