Timers

	Problem	Probable cause	Solution
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.)
Timers	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.
