Electrical Protection
The TCU has an external cartridge fuse as well as an internal AC/DC power supply with overcurrent protection. The TCU
shuts down logic and 9.5VDC and should the voltage continue to fall to 9.1 will shut down theTCU. Likewise, the TCU
will recover from the logic shutdown at 11.0VDC and resume control. However, if complete shutdown occurred it will not
turn back on until 12.3VDC.
Battery Backup (Optional)
An input is provided for connecting a battery to the TCU at connections P1-8 and P1-9. Connecting a battery to the TCU
allows it to communicate and operate (albeit without the ability to run pumps) when primary AC power is lost. The alarm
horn and light can be powered from the battery to provide alarm functionality during a power outage. All digital monitor
inputs using ISO+24V (P2-16) as a bias-voltage source continue to function. If power fails, and the TCU is connected to
telemetry, the power outage is reported to the central site.
The TCU includes a battery charger circuit that can be used to float charge a battery for backup operations. Note that
statistical and configuration data is retained even without a backup battery. The purpose of the battery is to maintain
telemetry functions during a power loss.
Operating run times for a typical application running on battery power:
• 12V, 2.6Ah battery - 2 to 3 hours
• 12V, 7.0Ah battery - 6 to 8 hours
These numbers are for a new, well-maintained, and fully charged battery. As the battery ages, operating run times may
diminish. Larger capacity batteries can be substituted for longer lifespans. Please contact DFS if specific lifespans are
required.
The TCU monitors the voltage and will begin a safe shutdown if the battery voltage drops below 9.1 VDC. It will not come
back up until the voltage reaches 12.3 VDC.
