Features
- VFD
- The TCU800 VFD mode is now software configurable and integrated in the normal TCU800 firmware. You no longer need to flash a separate firmware on the TCU to enable VFD mode.
- All features, settings, and abilities from the VFD TCU001 firmware have been ported to the TCU800:
- Previous VFD specific alternation methods (Pump 3 Lag, Lag2 Standby, and Lead Pump) have been added as regular alternation methods in the Alternation settings menu.
-
- Variable Level and Fixed Level Process Control algorithms have been ported to the TCU800.
- All TCU001 VFD settings have been added to a new VFD settings menu in the TCU800 settings menu. This page is only displayed when the TCU800 is placed in VFD mode.
- GUI
- Added VFD Speed Tuning page to TCU menu. This allows the speed output of all pumps to be dynamically changed by a user without input from a Process Control algorithm. It is suggested to use this for troubleshooting or tuning.
- Changed "Timed Pump Alternation" setting name to "Alternation Suspension Timer".
- Changed Modbus Server default protocol to be RTU no parity. It is recommended at this time to use RTU no parity instead of ASCII.
- Screensaver settings have been added to the TCU Settings settings menu. This adds the ability to enable or disable the screensaver backlight timer as well as configure the time it takes for the TCU800 to sleep on AC or BAT power.
- Fixed settings change confirmation table not showing full list of changes when many, many changes are made.
- Added VFD Mode toggle in the Advanced Settings menu.
- When enabling VFD Mode, a prompt will ask which complimentary external product is being paired with the TCU800. Selecting a product will pre-populate the Modbus settings needed to communicate the device. This will erase any previous Modbus config on modules H-K to lock in the Modbus settings needed to pair with the external product.
Bug Fixes
- Transducer behavior changes
- In the 5.11.5 Rapid Response update, changes were made to the Transducer fault’s behavior when a fault occurred. These changes have been considered and re-worked:
- The transducer level no longer “locks up” on the TCU800 screen or telemetry traffic when a fault occurs.
- Added “XDCR Fault” alarm indication to quick view.
- When the transducer fault backup mode is set to “Disabled” and a transducer fault occurs, the TCU800 will now enter an alternative mode of operation referred to as “Emergency Mode” until the Transducer Fault is cleared:
- If the High is enabled and the Low IS enabled: The TCU800 should continue to pump until the low float is hit and then do nothing until the high float is hit again. This repeats until process restart.
- If the High is enabled and the Low IS NOT enabled: The TCU800 should continue to pump for the minimum pump runtime and then do nothing until the high float is hit again. This repeats until a process restart.
- When a transducer fault occurs, the transducer is NO LONGER consulted for the pump algorithm.
▪ When enabling the High or Low Float option in the Floats setting menu, the matching XDCR High/Low Float Fault setting will be enabled with it automatically.
