PURPOSE:To ensure the test and repair for the faulty terminal unit without stopping the operation of the entire system for the mimic practice unit which actuates plural units of terminal units by providing the change-over switch to connect the arithmetic circuit for test and the terminal unit when testing the terminal unit. CONSTITUTION:In the mimic practice unit to actuate terminal units 31-3n, arithmetic process circuits 21-2n connected to control circuit 1 which gives the command to each terminal unit are provided, along with testing arithmetic circuits 41-4n to give the test to each terminal unit in connection to circuit 1. Then change- over switches 51-5n are connected between units 31-3n, circuits 21-2n and circuits 41-4n each to be operated when the test is given. Thus, the test and repair can be given to the faulty ones among units 31-3n without stopping the operation of the entire system. |
