Timers | A sensor was used to turn the power supply to the Timer ON and OFF, but the sensor output was damaged. | The inrush current when the power supply voltage was applied may have damaged the sensor output. | Use an MY or other relay to turn the power supply to the Timer ON/OFF. (Use a suitable contact capacity.) |
The top part of the display on a Timer with a memory backup is missing. | If the power supply is not connected and power is interrupted for 10 minutes or longer, the measured value or display will not be dependable and unnecessary outputs may appear. | Always connect a battery when you use a Timer with a memory backup. If the battery voltage is 3 V, you can use various type of batteries. The memory backup time will depend on the capacity of the battery. |
