LOAD CONTROLLER AND LOAD CONTROL METHOD
PROBLEM TO BE SOLVED: To provide a load controller and a load control method which can bring a load back to a normal operating state in a short time as much as possible when the load operates differently from a desired operation due to the occurrence of an earthquake. SOLUTION: When a vibration sens...

description | PROBLEM TO BE SOLVED: To provide a load controller and a load control method which can bring a load back to a normal operating state in a short time as much as possible when the load operates differently from a desired operation due to the occurrence of an earthquake. SOLUTION: When a vibration sensor detects the occurrence of an earthquake (S2), a load controller stores a load control state at the moment in a memory (S3). When an earthquake sensor detects the termination of the earthquake (S5), the load controller reads out the stored load control state (S6) and compares it with a current load control state. If there is a difference between the two load control states, the load controller instructs an output circuit to supply power or stop power to a relay circuit to bring the load back to the load control state at earthquake detection (S8).
