Abstract

PURPOSE:To ensure a safe maintenance/checking work, by installing a changeover switch which can be switched to the usable mode, the checkable mode and the excludable mode to the module forming relay and then interlocking the computer output according to the switching mode. CONSTITUTION:In the usable mode of the computer 8, the kick signal (a) is delivered from the output function and according to the control condition, and each of the module forming relays stored in the storing board for module forming relay 12 is energized to drive the control subject complementary machinery 10. The changeover switch indicating the usable mode, the checkable mode and the excludable mode is provided to each relay. Then the contact signal which is turned on in the usable mode of the switch is sent to the computer 8. The monitor function for module forming relay 15 delivers the interlock signal (c) only when all contact signals are on. Accordingly, the signal (c) is never delivered mistakenly in the unusable state.
