5、09 Superseding J1493 JUL2008 Guarding of Starter System Energization RATIONALE This standard has been revised to clarify that Agricultural Tractors are included in the scope. The 2013 revision to SAE J1116 removed Agricultural Tractors from the scope of that standard however provided a means to cont
6、inue to include Agricultural Tractors in SAE standards that are also applicable to agricultural tractors. 1. SCOPE This SAE Standard describes guarding to help prevent hazardous machine movement caused by activation of the starter motor by bypassing the starter control system. This document is appli
7、cable to off-road, self-propelled work machines, as identified in SAE J1116 and Agricultural Tractors as defined in ANSI/ASAE S390 which have the potential for hazardous machine movement as a result of bypassing the starter control system and powering of the starter motor. 2.

DEFINITIONS 3.1 HAZARDOUS MACHINE MOVEMENT Unexpected machine movement resulting from power supplied to the starter motor with the machine ground drive or work function drive engaged which has the potenti
11、al to cause injury. 3.2 STARTER CONTROL SYSTEM The system consisting of the components used for controlling battery power to the starter motor. These components typically include the start switch, neutral switch, solenoid and relay. 3.3 STARTER MOTOR SOLENOID The power relay that supplies power to t
12、he starter motor from the battery. 3.4 TERMINAL The electrical connection point such as a stud or a spade, connecting the cable and the device including the uninsulated portion of the cable which is connected to the device. 3.5 COIL TERMINAL The terminal used to connect the starter control system ci

REQUIREMENTS 4.1 Guarding of the starter motor solenoid shall prevent the electrical connection of battery jumper cable clamps to the motor terminal (3). Guarding of the starter motor solenoid shall also prevent electrical
15、 connection, by using pliers or a flat rigid conductor such as a screwdriver, between the battery terminal (2) and either the coil terminal (1) or the motor terminal (3). Guarding by location or other means determined by risk assessment to be effective are acceptable protection means. Removable guar
16、ding shall be fastened in place with a device that requires a tool for removal or to open. SAE INTERNATIONAL J1493 Revised SEP2013 Page 3 of 3 4.1.1 With the starter motor solenoid guard removed and the wiring attached, if an electrical connection (at the starter motor solenoid) causes the engine to
17、 crank, a fixed barrier on the starter motor solenoid shall prevent electrical connection by using a flat rigid conductor such as a screw driver between either the coil terminal (1) or the motor terminal (3) to the battery terminal (2). 4.2 Other means of preventing hazardous machine movement caused
18、 by activation of the starter motor by bypassing the starter control system are acceptable as alternatives to the fixed barrier or guarding stated in this document. 5.
