Usage of Device and Working Principle:
Please connect the device according to the diagram.
On-Time: Sets the stage of “on” and displays the maximum “on” time.
Off Time: Sets the stage of “off” and display the maximum “off” time.
ton: Divides the“on”time by 10 and multiples by displayed value.
toff: Divides the“off” time by 10 and multiples by displayed value.
Example: Working time(on) is 75minutes, waiting time (off) is 60seconds.
Turn on the stage button to 100m and ton button between 7-8.“On”time will be adjusted to 75 minutes.
Turn off the stage button to 100s and toff button to 6.“Off“ time will be adjusted to 60 seconds.
Note: In order to adjust much sensitive higher time values, set “t” by chronometer in low stages and increase the stage to the
time required.
Example: Working time (on) 7,5 hours and waiting time (off) is 50 minutes.
Turn on the “on” stage button to 10s. and “ton” button between 7-8. Power on the device and check for 7,5 seconds with
chronometer. If it is high or low, re-set “ton”.Power on and check again. Later, turn on the “on” stage button to 10h, in this
case “on” time will be much precise.
Turn on the “off” stage button to 10s. and “toff” button to 5. Power off the device and check for 5 seconds with chronometer. If
it is high or low, re-set “toff”. Power on and check again. Later, turm off the “off” stage button to 100m, in this case “on” time
will be much sensitive. After time settings, power on the device. at the beginning,
“on” time will count and“on” led will flash. While counting, relay contact out is (NO)3. When the counting finishes,“ff” time will
start to count and off led flashes.While counting“off” time, relay contact out is (NC)1. Till the power is off, device keeps
counting on and off times in turn.
