Spartan Guard Locking Compact Housing

The Spartan from Rockwell Automation Safety Products Guardmaster™ is a positive mode, tongue operated guardlocking interlock switch that locks a machine guard closed until power is isolated and ensures that it remains isolated while the guard is open. It is available in two contact configurations: two safety (N.C.) contacts and one auxiliary (N.O.) contact (Spartan 1) or three safety (N.C.) contacts (Spartan 2). The Spartan head has two entry slots and it can be rotated to provide four actuator entry points. A blanking plug is provided to seal the unused slot.

The guard may only be opened when a signal is applied to the Spartan’s internal solenoid which releases the lock mechanism. This signal can be via CU1 Electronic Timer Relays or CU2 Stopped Motion Detectors. Therefore the Spartan is ideal for machines which do not stop immediately or where premature interruption of the machine could cause damage to tooling and components or cause an additional hazard.

The locking mechanism withstands forces up to of 1200N (270lbs.) and an LED provides visual indication of switch status.
A catch kit with actuator alignment is also supplied to relieve stress on the locking solenoid and to protect the unit from actuator damage due to poor guard alignment. Manual release points with security screws or special key allow the locked Spartan to be released in the event of total power failure on a machine.
