|
||||
 |
||||
|
|
||||
| The Hercules is a s ingle key access interlock complete with electrical contacts suitable for use on hinged and sliding doors . The Hercules contacts can be used to switch of the machine via its control circuit or to initialize a signal to visual beacons / sounders . The switch is sealed to IP65 and provides 1n/o 2n/c contacts, making it suitable for use in cross - monitored safety systems . The interlock has an open cavity design and is manufactured in a durable stainless steel making it ideally suited to use in harsh or corrosive environments where the lock is subject to heavy use. Typical industries using the AI are food, chemical, quarrying and aggregates, steel and pharmaceutical. |

| Under normal operating conditions the key and the sidebolt are trapped in the lock with two switch contacts closed and one open. The key is released which changes the switch contact condition to 1n/c 2n/o and releases the sidebolt. With the key and sidebolt removed, the switch condition cannot be reversed. An alternative condition is available where the key has to be inserted to allow removal of the sidebolt. | ||||

The Hercules is designed to operate as part of an integrated safety system, controlling acces s to hazardous areas . A typical example of machine isolation and acces s control is shown below.

The removal of the key from the Hercules isolates the electrical supply to the machine and allows the removal of the sidebolt. This key is then taken into the area by the operative to safeguard agains t accidental lock in or start up or to initialize another part of the proces s , i.e. switching the machine into a teach mode. The guard can only be opened when the electrical supply has been switched into a safe condition. |
