On (steady) A fatal error is present (no communication).
Off There are no errors.
FORCED I/O
(Color: red)
Flashing One or more input or output addresses have
been forced to an On or Off state but the
forces have not been enabled.
On (steady) The forces have been enabled.
Off No forces are present or enabled.
BATTERY LOW
(Color: red)
On (steady) The battery voltage has fallen below a
threshold level or the battery and the battery
jumper are missing.
Off The battery is functional, or the battery
jumper is present.Control Techniques MD-434-00-000
