Functions
1. The solenoid valve timer adopts flame retardant ABS shell.
2. Uses knob for adjusting time, adjustment range: ON state for a cycle time of 0.5-10sec, OFF state for a cycle time of 0.5-99min.
3. Service voltage: AC/DC 24-240V
4. The IP grade of this electronic timer is IP65.
5. With standard DIN43650A input / output interface.
6. LED light indicates the state of ON and OFF.

Initial State
When power on, LED indicator is lighting at ON, the timer starts to work with the current output, after reaches the time which is adjusted previously by ON, LED indicator switches OFF automatically; at the same time LED indicator is lighting at OFF, there is no current output, and timer stops to work, after reaches the time which is adjusted previously by OFF, LED indicator switches ON automatically. This cycle is repeated until power is removed.

Time setting
1. ON: rotates adjustable knob, and makes arrow pointing to the time needed to be set, (for example: pointing to number 8, means the cycle time is 8 seconds, if pointing to the number between 8 and 10, means the cycle time is 9 seconds), the time set by ON will start to work at the next cycle.
2. OFF: rotates adjustable knob, and makes arrow pointing to the time needed to be set, (for example: pointing to number 0.5, means the cycle time is 0.5 minutes, if pointing to the number between 10 and 20, means the cycle time is between 10 minutes and 20 minutes), the time set by OFF will start to work at the next cycle.
3. Manual Test
The solenoid valve timer does not response after press TEST key at ON state, which is available when press the TEST key at OFF state, at the same time, the timer enters the next initial state, that is ON state, and then the LED indicator is lighting, the timer will start to set the time.
