Standards Single Dual 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. Features • Electrical safety contacts combined with trapped key/enforced sequence feature • Most of unit constructed from 316L stainless steel • Selection of actuator types available • Single or dual key versions available • Direct drive operation • Replaceable code barrel assembly • Weatherproof stainless steel dust cap as standard The Prosafe Advantage Stainless steel construction. 5-26 Prosafe Trapped Key Interlock Switches Slamlock Electrical Product Selection Contacts Type Key Condition Key Trapped to Release Actuator Single Key Key Free to Release Actuator 2 N.C. + 1 N.O.
