PURPOSE:To enable the checking for the setting of relay output quickly and accurately with one setting by visual or audio indication of the results of the comparison which is made by a time switch according to the operation of a key. CONSTITUTION:With one operation of a checking switch at a key section 3, the address is spaced sequentially through a CPU1 and a set time stored in an RAM2 and setting conditions of relays 7 and 8 and the like are read out sequentially and the time is displayed on an indicator section 4 while the setting conditions are compared with an output pattern of a program memory 9 in ROM by means of a comparator section 901 of the memory. With an output for non-coincidence or the like from the comparator section 901, a warning is generated from a buzzer 10. With such an arrangement, the checking for plural output settings of timer relays can be performed quickly and accurately. The same can be carried out by a visual indication in accordance with the coincidence and non- coincidence signals. |
