BATT_TEST_SEQ
Supervised battery discharge test: preconditions, timed discharge, immediate abort and a recorded pass/fail with the load it was run at.
When to use it
Use BATT_TEST_SEQ when a UPS battery string is proof-tested by discharging it into the live IT load for a fixed period, and the test must not be allowed to become the outage it was run to prevent.

Supervised control write
BATT_TEST_SEQ commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
