Usage of Device and Working Principle

• Make the connections according to the diagram.
• Max.Time (Time Steps, TS ): Adjusts the stage and display the max.time.
• [ t ]: Divides the stage by 10 and multiply with displaying value.
  * Example: Time is 75 minutes.
• Make stage button to 100m (100 minutes) and turn “t” button between 7-8. In this case time is adjusted to 75 minutes.
  * Note: In order to adjust much sensitive higher time values, set “t” by chronometer in low stages and in crease the stage to the time required.
  * Example: Time is 25 hours.
• Turn stage button to 10s (10 seconds) and “t” button between 2-3. Make power on and check with a chronometer for 2.5 seconds.
• Make the stage button 100h(100 hours). In this case, you set it more sensitive.
• After setting the time, power on the device. Device will start timing and meanwhile led switches on-off.
  When device is timing relay contact 2 shorted to 1.
  When the timing finish (set time is up) relay led is switches on stable and contact 2 shorted to 3.
  Device keeps stable till the power is off.
