Fault ON A sensor has gone out of range of a configurable threshold
Note: When power is first applied to the E-2D or -5D, both the Power LED (green) and Fault LED (red) will illuminate for
the first 30 seconds of the boot process. After this the fault LED will turn OFF until a sensor alarm is generated which
will turn the fault LED back ON.
System Reset Button
A reset button is located on the front of the ENVIROMUX (see Figure 134). The button can be used to reboot/restart the firmware
of the ENVIROMUX. Pressing this button supersedes the use of the power on/off switch and battery backup to allow the firmware
to easily reboot in the event of a system lockup. To activate a reset, momentarily press the button with a pen or other small
pointed object. The ENVIROMUX will reboot and be ready for login within its usual start-up time period.
