4. Operation

4.1. Front Panel

Status LEDs on the front of the module provide visual indications of the module’s operational status

and field input status. Each LED is a tri-colour LED of which for normal operation, only two colours are

used; red and green. Located at the top and bottom of each module is an ejector lever that is used to

remove the module from the chassis. Limit switches detect the open/closed position of the ejector

levers. The ejector levers are normally latched closed when the module is firmly seated into the

Controller or Expander Chassis.
