immediately illuminate all LEDs. This shows the system was rebooted.
Rebooting a Unit (with Hardware Timer)
Press and hold the button for approximately 20 seconds. At the 20 second point, all LEDs will illuminate. Note: this length
of time will only occur if one holds the button down through the software reset window. The purpose behind the hardware
reset is to allow the user to reboot the box even if the software has been locked.
Sleep and Wake
When the unit is powered and running, the screen will sleep after 15 minutes of user inactivity. Momentarily pressing the
button will wake the screen.
Silencing the Alarm Horn
If the alarm horn sounds, it can be silenced by momentarily pressing the button.
Returning to the Home Screen
To return to the Home screen, press the button once.
USB Ports
The TCU800 faceplate has two USB ports: the Configuration port and the Service port. Their purposes are station address-
ing and configuration, backup logs, service port access, and updating the TCU800 software.
Configuration Port
A removable USB drive replaces the address strap functionality and adds the ability to alter all TCU800 profile configura-
tion options. A congifuration USB can be placed in either of the two USB ports.
Boot-Up : When the TCU800 boots up, it checks for a USB with a configuration, loads it, and saves it internally. If no con-
figuration USB drive is available or the USB drive has failed, the TCU800 will use the last stored configuration.
Configuration Change
: When a configuration change occurs, the USB and internal configurations are updated.
Service Port
The TCU800’s service port is used for debug access and as a secondary method of configuration.
Touch screen
The TCU800 has an LCD with an integrated, capacitive touch screen. This displays all information pertinent to the pump
control algorithm as well as providing an interaction point for many operations and configurations (discussed in the detailed
operation section).
Never remove a USB drive under power. Ensure the TCU is in a shutdown state before removing the USB--
failure to do so may corrupt the configuration or damage the drive.
