Wherein the remote brake switch SGT remotely controls whether the brake signal point RTD is energized, thereby controlling whether the speed limiter controls the elevator to stop. The remote release switch SGR controls whether the release signal point RRD is powered up, thereby controlling whether the speed limiter releases the elevator.
In this example, the remote brake switch SGT, the brake signal point RTD, and the voltage signal point 301 are connected in series to form a brake control circuit, and the remote brake switch SGT is used to control the on-off of the brake control circuit.
In this example, when the remote brake switch SGT is closed, the brake control circuit path and the brake signal point RTD are energized. When the braking signal point RTD is powered on, the speed limiter brakes the elevator, so that the elevator is stopped.
In this example, the remote release switch SGR, the release signal point RRD, and the voltage signal point 301 are connected in series to form a release control circuit, where the remote release switch SGR is used to control the on-off of the release control circuit.
In this example, when the remote release switch SGR is closed, the release control circuit is on, and the release signal point RRD is powered. When the release signal point RRD is powered on, the speed limiter releases the elevator to enable the elevator to run.
