either independent or voted in a 2-out-of-3 confiquration. An isolated bus architecture is used to shareall inputs

and latch status information between the three modules. Optionally each ProTech-Gll modulecan be configured

to use only its sensed “local” input signals or the voted result of all three modulessianals in its event latch decision

logic, Optionally module trip and alarm latch statuses can also beconfigured to be shared with all other modules.

The ProTech-Gll includes Overspeed and Over-acceleration functions as well as time stamped Alarm,and Trip logs. indication that a
