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.
