Set Features :

Panel

1.Highlighted by the five red LED display, from right to left as the first, second, third, fourth and fifth.

2.By three micro-buttons, from right to left are: Reset button (preset number of settings), shift key, change the number of keys.

Delay and subtrahend setting function

1.Long press "Reset button (preset number of settings)" button "15 seconds, automatically set the state of delay, the screen displays" - ", the first flash, this screen for the controller, the internal relay pull-in time Set the length (in seconds) to delay preset. Can "shift" key, so that the current flash bit left one, the first one → Page 2 → Page 2 → Page 4 → Page 1 cycle, but also can "to a few" key so that the current flash bit figures by one. If the controller should not delay the internal relay pull-in functions, this screen is set to "-0,000", work status pre-subtraction to 0, you must manually click "Reset button (preset number of settings)" key to re-zero.

2.And then click "Reset button (preset number of settings)" key to enter the screen displays " ", the first one blink, this screen is set for the preset value subtraction. The required quantity can be preset. To 0 within the relay output contact signal controller, played down, or other electrical circuitry controlling role. Set the method of data Ibid.

3.And then click "Reset button (preset number of settings)" key, the screen is set out to show the value of pre-subtraction can be carried out by counting the work of the input signal. Namely, working state, this state at any time click "Reset button (preset number of settings)" key, it can be re-set pre-subtraction value from the beginning.

4.In short: Work status of long-press "Reset button (preset number of settings)" button for more than 10 seconds into the set state.

Working condition points, click "Reset button (preset number of settings)" button, or reset.

Workflow:

Example 1: Relay closure time settings, "-0,100" seconds, the preset value is set to "01000" months, each time to a signal by a preset value, until reduced to 00000, relay closed, the screen displays "-0100" seconds, that is, real-time display relay closure time of the countdown, until reduced to 0 seconds, the relay was broken, and again the screen displays "-01.0 thousand," preset value, once again, start again. In the reduction process, according to "reset button (preset number of settings)" re-start from a preset value set by.

Example 2: Relay closure time settings, "-0,000" seconds, the preset value is set to "02000" months. Every time I come a signal, the preset number by one, until reduced to 00000, relay closed, the screen displays "-----", at this time follow the "reset button (preset number of settings)," Manual Reset, after disconnect electrical appliances before, and again the screen displays "02000" preset value, and then once again from the beginning set the value of pre-subtraction.

Notes:

1, make sure that the counter before wiring identify whether the power supply voltage line in accordance with wiring diagram correct wiring.

2, the counter signal input circuit should be as close as possible counter terminals, the input lines as short as possible, avoiding contact with other strong wire, power line alignment with the tube or strands, if necessary, use shielded wires.

3, contact input should be reliable, so as to avoid contact bounce caused by incorrect count. If error count, can be 5,6 feet next 1 ~ 10F electrolytic capacitor (only applies to non-voltage input type).

4, the use of proximity switches, photoelectric switches type sensors for counting the signal source should be used in counter-voltage input type (ie, voltage input count), and should pass the rated voltage of the same receptors (such as: mass receptors for AC220V, when the chosen The counter should also be AC220V input type, and other specifications and so on).

5, no-voltage input type counter, counting may not enter more than DC30V input voltage, otherwise it will damage the counter.
