4. Operation
4.1. Front Panel
Status indicators on the front panel of the module provide visual indications of the module’s operational
status and field output status. Each indicator is a bicolour LED. 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.
