Repeat the process for each pad connected to the control unit and check that the corresponding channel fault turns red. Note that the channel fault status indicates the operation or fault of a single pad. Automatic reset of control unit operation mode Automatic reset of power supply and machine enabling light up. The machine is enabled when the mat is working. The standby mat is enabled. The machine is enabled. The manual reset is on. The power is on. The manual reset and the machine is enabled are on. Press the reset button. If the machine is enabled, it will light up while the mat is running. If the machine is enabled and the LED is still off, press the reset button. If the machine is enabled and lit up, the light that the machine is enabled will go out. Resetting is not allowed until the fault is eliminated. In the fault state, if there is a mat fault, one or more mat states will light up. In case of open circuit or short circuit, it will light red. If there is a fault and none of them light up, the control unit is faulty. Check the safety function of the single channel system. Refer to Figure and Section to simulate normal operation. Stand on the mat and start the mat, and check whether the main contactor falls off immediately. Check that any other safety related stop functions, such as the brake clutch contactor, operate as expected. The dual channel system is shown in Figure and Section to simulate normal operation. Stand on the mat and start the mat, and immediately check whether the two final contactors fall off. Check whether any other safety related stop functions, such as brake clutch contactor, operate as expected. Isolate the power supply and then install a temporary fault diagram or by short circuiting the terminals at the terminal block. Restore the power supply and start the sensor pad and check that one of the final contactors is immediately disconnected and that any other stop functions associated with that channel are operating as expected. Check that the control unit will not reset the isolated power supply and eliminate temporary faults. Restore the power supply and check whether the mat subsystem works normally. Take the same electrical safety precautions, temporarily short circuit between terminals and of the terminal block, and repeat the test diagram or. Checking the control unit again will not reset the temporary fault check pad system. Carry out any other tests required for all system types to confirm that the safety related control system meets the specified category requirements and works as expected. Check for any other safety functions related to the machine circuits that are affected by the installation of the mat system. These tests should have existing procedures. Isolate the power supply of the machine at the power supply. Reconnect any automatic reset functions provided by the machine control system. Reconnect the machine prime mover to the final contactor. Secure all covers and doors. Function check to restore machine power. Check. The machine cannot start operation until the mat control unit is reset.
