安全回路。 In an electric circuit that has a main power system and an operating power system, and is provided with a clutch 11 that turns on and off the power transmission from the main power system to the working power system, and that electrically operates the on and off of the clutch 11, Tsute clutch 1
A keep relay 27 for turning on and off the switch 1 is provided, and the operating circuit for making the contact of the keep relay 27 includes a seat sensor 13 for determining the presence or absence of an operator.
A manual operation switch 21 is included in the return circuit that connects the step sensor 15 and the operated contact.
and the keep relay 27 is a work power system clutch on/off safety circuit which disengages the clutch 11 when both the seat sensor 13 and the step sensor 15 determine that there is no operator present.
