Zusammenfassung:	To shorten a time required to find out the cause of a failure in a controller.SOLUTION: A controller 30 that controls the operation of a valve 28 based on a pulse signal, comprises: a pulse converter 34 that generates a pulse signal for operating the valve 28; a detection unit 36 (36a, 36b) that detects the pulse signal output from the pulse converter 34 or the pulse signal input to the valve 28; and a determination unit 38 that determines whether the pulse signal is a normal signal or not based on a conversion signal obtained by converting the pulse signal detected by the detection unit 36 (36a, 36b).SELECTED DRAWING: Figure 2 【課題】制御装置における不具合の原因を突き止めるまでに要する時間を短縮する。【解決手段】制御装置３０は、パルス信号に基づいて弁２８の動作を制御するための制御装置３０であって、弁２８を動作させるためのパルス信号を生成するパルスコンバータ３４と、パルスコンバータ３４から出力されたパルス信号又は弁２８に入力されるパルス信号を検出する検出部３６（３６ａ，３６ｂ）と、検出部３６（３６ａ，３６ｂ）で検出されたパルス信号を変換した変換信号に基づいて、パルス信号が正常な信号であるか否かを判定する判定部３８と、を備える。【選択図】図２
