Description
The Prosafe Slamlock with electrical isolation combines the features
of trapped key tongue actuated interlocks while also providing sets
of electrical safety and auxiliary contacts. When the actuator is
inserted into the lock and the key is removed the actuator is trapped
in the unit thus locking closed the guard door. In this state the safety
contacts are closed and the auxiliary contacts are open. To open the
guard door the key must be inserted and rotated 90°, opening the
safety contacts, closing the auxiliary contacts and enabling the
actuator to be released thus unlocking the guard door. While the
guard door is open the key is trapped in the unit.
Slamlocks with electrical isolation offer the features of electrical
safety interlock switches with the benefits of a trapped key/enforced
sequence systems. They allow a combination of both approaches for
safeguarding machinery and processes to be used.
The single key Slamlock (SSS) is used to interlock hatches, guards
and doors where full body access is not required. The single key
locks the actuator and operates the switch in the same action.
Dual key Slamlock (DSS) is similar to the single key version but has a
secondary key to allow ‘2 key in’ or ‘key exchange’ conditions. The
key exchange version may be used where whole body access is
required, as the secondary key can be used as a personnel key.
