<p>PROBLEM TO BE SOLVED: To obtain a necessary sensor signal data without stopping the recording into memories even when an auxiliary contact signal is affected by noises and surges. SOLUTION: A memory 20 for breaking current data and a memory 21 for gas pressure data have a plurality of banks. A bank switching control circuit 24 to be operated by a signal of an auxiliary contact 11 and a record address holding circuit 25 are arranged together with an address generation circuit 23 to the memories 20 and 21. Thus, a necessary sensor signal data can be obtained without stopping the recording into the memories even when an auxiliary contact signal is affected by noises and surges.</p> |
