Module Interlocks

Module interlocks are a safety feature that prevent operator injury. Lifting a

hood causes the motors to be disabled and the interlock indicator light for the

module(s) to go off. Interlock lights for the adjoining modules go off, but the

adjoining modules finish processing passports and then sit idle with motors

enabled.

Most systems have connected hoods so that all or many modules lose power to

the motors when hoods are opened. Wider modules have one interlock on the

upstream side.

The Output module has its own hood and a Pause/Resume switch. When the

hood is opened, motors in the upstream module are disabled. The Input module

also has its own hood. When the hood is opened, it disables the motor of the

module adjacent to it.
