Low voltage and short circuit

Low voltage shutoff

When the internal canister voltage drops below 8V, the output channels will turn off.

After a 2 minute timeout, the voltages will be measured and output channels will restart if they exceed the low voltage threshold.

The output channels will attempt to restart two times. After the maximum retries, the channels will remain off until the canister is reset. See Battery canister reset/restart for more information.

To confirm if the canister is in a low voltage shutoff state, remove it from the housing. If a low voltage shutoff has been initiated, the LEDs will slowly flash red (1s/10s on-off).

Short circuit protection

If the output current of any one channel exceeds 5A, the output voltage to that channel will turn off.

After a 2 minute timeout the output channels will restart with the output current being monitored.

The output channel will attempt to restart two times. After the maximum retries, the channel will remain off until the canister is reset. See Battery canister reset/restart for more information.

To confirm if the canister is in a short circuit state, remove it from the housing. If the short circuit condition is still present, or the battery has exhausted the maximum number retries to re-enable the affected channel, the LEDs will flash red fast (3x every 2s).

Battery canister reset/restart

To reset/restart the RBRfermata, remove battery power from the canister by taking out at least one battery from each column for at least 5 seconds.
