48 **Notes:**
49 The **OUT_WORK **signal signals the operation of the device’s main program and is generated when the device is turned on.
50 The **OUT_ERROR **signal indicates a critical device error or a low insulation resistance value.

74 The **OUT_WORK **signal signals the operation of the device’s main program and is generated when the device is turned on.
75 The **OUT_ERROR **signal indicates a critical device error or a low insulation resistance value.
76 The **KEYRUN_1 **and **KEYRUN_2 **signals are equivalent and are intended to trigger the device’s power supply circuit. Can be connected to the V+ device supply line.
