Note: 1. K8AB-PW output relay is normally operative.

2. The power ON lock function prevents unnecessary alarms from

being generated during the unstable period when the power is first

turned ON. There is no relay output during timer operation.

3. L1 and L2 use the same power supply and will not operate due to an

undervoltage if they drop below the rated input of 60%.
