What stopping means is to be disabled for the emergency terminal stopping test?

The concept of stopping means refers to the protocol that is engaged during testing to ensure that a lift or elevator reliably reaches its designated stopping points under emergency conditions. In the context of the question, the normal terminal is the correct stopping means to be disabled for the emergency terminal stopping test.

Disabling the normal terminal allows for a test of the system's emergency stop functions without interference from the regular terminal stopping mechanism. This ensures that the emergency systems are functioning correctly and that the elevator is capable of stopping at the emergency terminal when needed. By focusing the test on the emergency terminal, the reliability and effectiveness of the emergency systems can be evaluated without the normal stopping mechanisms potentially overriding or interfering with the process.

The other options refer to various types of terminal stops, but they do not apply to this specific context of testing emergency systems. For instance, the backup terminal would provide an auxiliary stopping function, while the emergency terminal is the focus during the test itself. The safety terminal relates to overall safety compliance but is not the correct stopping means to disable for this specific testing scenario.
