What type of maintenance can be conducted using the service button?

The service button in an elevator system is specifically designed to allow for specific control during repair work. When activated, it can enable technicians to place the elevator into a service mode, where they can operate the elevator more directly and manage its controls without interference from the regular passenger call buttons. This is essential for safely performing maintenance or repair tasks, as it ensures that the elevator does not respond to general calls while the technician works on it.

While routine cleaning and other options may involve some interaction with the elevator, they do not specifically utilize the service button for direct control or operation. The primary purpose of the service button is to facilitate maintenance and repair activities effectively and safely, ensuring that the elevator can be controlled in a manner that prioritizes technician safety and minimizes the risk of accidents during service work.
