PROBLEM TO BE SOLVED: To solve the following problem: If any of difficult-to-obtain relays used on a control substrate is failed, the control substrate is usually replaced with a new control substrate for repair; therefore, even when only one relay is failed, all the relays needs to be replaced, however, repair itself becomes difficult because they are difficult to obtain. SOLUTION: A substrate for repair with a relay for repair that functions in place of a failed relay is connected to a connector for inspection, an on-off command to the failed relay is always monitored, and the relay for repair is turned on and off, interlocking with the on-off command to the failed relay.
