My Russian is a little rusty, but my translation is roughly this:
They performed the next test of the engine, this time with added systems for protection from off-nominal situations.
The goal was to test the reliability of the protection system of the rocket engine.
During the test of the NK-33A engine after reaching the maximum values of the off-nominal shutdown sensor, the control function of the engine worked on time. The engine was shutdown at the necessary moment.
The check of the engine protection systems will be continued. The next test is planned soon.
