2. Working mode:

After turning on the power, the digital tube will display the words "E-A-Z-y-t" in turn, and then enter the mode selection state, the initial mode selection display is

"P-0", press the SET key to select the 8 modes "P-1 ~ P-8", and press the ENTER key to enter the corresponding mode. Stop in either mode

Press and hold the ENTER key for 3 seconds in the running state to return to the mode selection state. Press and hold the "SET" + "ENTER" keys at the same time and then turn on the power.

Then release the two buttons to restore the factory settings.

2.1 P-1 time (timing) relay mode

In P-0 mode, press the SET key once, the digital tube displays "P-1", and press the ENTER key to enter the time (timing) relay mode.

Loop execution:

In the time relay mode, the user can set the pull-in time T1 and the release time T2 of the relay, for example, set T1 to 3 seconds and T2 to 7 seconds.

Then when the relay is running, it will perform 3 seconds of closing and then releasing for 7 seconds, and so on.

After you set the T1 and T2 time values, the system will power off to save the set value, and the next time you run this mode, it will automatically load T1 time and wait

Start running. Press the ENTER key to start the timer.

Press SET to set the state of T1 and T2 time values, and then press SET to set the number of executions of the cycle, up to 999 times. Set the times to

0 means infinite loop execution.

When the timer is running, press and hold the SET key for three seconds and then release it to switch between the timing value display and the cycle times display.

Single execution timing:

If only T1 (pick-up time) is set, and T2 (release time) is 0, the relay will stop after timing T1 and no longer run in a loop.

At this time, it can be used as a timer, the T1 time is completed regularly, and the relay is released. At this time, press the ENTER key, and the system restarts at T1 time

Time.

If T1 (pick-up time) is set to 0, the setting of T2 (release time) cannot be entered, and the relay is always in the release state (do not start operation).

OK, normally closed point is connected, normally open point is disconnected).

1) Short press the SET key once, the first digit of the digital tube flashes, and the set three-digit value is the T1 time value (the highest digit).

1HZ frequency flashes, press ENTER key to increase the value from 0 to 9 at this time; short press SET key four times, the nixie tube flashes to skip the display value of T1 and enter

Enter the setting state of T2 time value; shortly press the SET key after finishing T2 setting, the third group entered is the cycle number setting, if the cycle number is

0, the timer executes in an infinite loop, short press SET until it exits the time setting state, and the system waits to start running;

2) In the setting state, it can be switched to the minute timer or the second timer. When the time is set by pressing the SET key shortly (the setting bit digital tube flashes)

Long press the SET key for 3 seconds to release, the rightmost digit of the nixie tube lights up (the decimal point lights up only when the SET key is released), indicating that the timing value is minutes.

If the decimal point is not bright, it means that the timing is seconds. After the setting is completed, short press the SET key to exit the setting state and wait for the timing to start. After setting timing value, when waiting for the timing state, press the ENTER key to start the timing, if it is a second timer, the second will display a countdown, if it is a minute timer,

The last decimal point flashes at a frequency of 1HZ, indicating that the countdown is running. When the timing is started, the relay is closed, the normally open point is connected, and the normally closed

When the timing ends, the normally open point of the relay is disconnected, and the normally closed point is connected, returning to the initial state of the relay. In timing operation, short

Press the ENTER key to pause the operation, long press the ENTER key for 3 seconds to return to the mode selection state.

In P-1 and P-2 modes, the start or stop of the time relay can be controlled through the external voltage/switch input interface (Figure 1, 2).

When the timer is running, the external switch input will not affect the timing operation. After the timing is over, the timing will start again when there is an external switch signal input.

Device.

A switch signal is required to trigger the start of the timing relay (the short-circuit cap is switched to the switch input terminal), or the rise of an external active voltage signal

Edge (from low level to high level), if the input switch does not work (or the level signal remains unchanged), the start timer will not be triggered.

If you want to start the timer automatically after the power is turned on, you can short-circuit the external switch port and place the shorting cap in the 1-2 position (that is, the external input is open).

Close has been closed).

2.2 P-2 time (delay) relay mode "P-2" mode is exactly the same as "P-1" mode setting, only the action of the relay is reversed, that is, enter the T1 time relay first.

Then enter the T2 time relay to close. For example, if you set the release time T1 of the relay to 3 seconds and the pull-in time T2 to 7 seconds, then the relay

When the device is running, it will delay for 3 seconds (maintain release) and then perform a 7-second pull-in cycle. If you set the number of cycles, the

After the loop ends, the relay is released. If the T1 time is set to 3 seconds and T2 is set to 0, the relay will be closed after a delay of 3 seconds.

2.3 P-3 voltage relay (voltage control direct action) Figure 34

In the mode selection state, press the SET key to select "P-3", short press the ENTER key to enter the voltage relay mode, and the voltage detection value (DC

0-99.9V), short press the SET key to set three-digit value, the set nixie tube flashes, the first to be set is the upper limit of voltage, short press the SET key four times,

Jump out of the setting of the upper limit of voltage, and then the lower limit of voltage to be set is the lower limit of voltage. Short press the ENTER key to increase the value from 0 to 9;

Do not exceed the upper limit (if the lower limit cannot be adjusted, please increase the upper limit first). After setting the upper and lower voltage limits, enter the next set of settings

It is the detection voltage correction value, you can short press the ENTER key to select the voltage detection value correction correction -0.3V～0.3V, short press the SET key to make the digital tube not

It flashes again and enters the voltage detection control mode. The system collects and displays the DC voltage value of the external input in real time. When the detected voltage exceeds the setting

When the upper limit of the voltage is set, the relay is closed (the normally closed point is disconnected, and the normally open point is connected) until the voltage is lower than the set voltage lower limit, the relay

Only release (normally open point is disconnected, normally closed point is connected).

In the state of detecting voltage, press and hold the SET button for three seconds and then release it, the logic state of the relay will be reversed. You can use this operation to achieve voltage

The relay pulls in if the upper limit is exceeded, or the voltage is lower than the lower limit.

If your voltage upper and lower limits are set to the same, such as 12.0V, then if the detected voltage value fluctuates around 12.0V, it may cause the relay

The inverter operates frequently, so it is recommended to set a certain hysteresis between the upper and lower voltage limits.

Note: The detection voltage terminal should be contacted reliably. Loose wiring and no insulation around the circuit board may lead to inaccurate voltage detection values.

2.4 Voltage control time relay mode (delayed on or delayed off) "P-4, P-5" mode is "P-1 timing relay mode" or "P-2 time delay relay mode and "P-3" Voltage Relay Mode" group

Close, "P-4" mode can be used for delayed on function, "P-5" can be used for delayed off function. After you set the timer operating parameters, enter the "P-4" or "P-5" mode to detect the voltage to control the start or stop of the timer

only. At this time, short press the SET key to set the upper and lower voltage limits and voltage correction value of the control timer. The setting method is the same as that in section 2.3. By long press

Release the SET key for three seconds, and you can choose whether the voltage exceeds the upper limit to start the timer, or the voltage falls below the lower limit to start the timer. In P-4 mode, when the timer is set to exceed the upper voltage limit to start the timer, the relay below the lower voltage limit will remain released (the normally open point is disconnected,

Normally closed point connected). On the contrary, when the timer is set to be lower than the lower voltage limit, the relay will be released when the voltage is higher than the upper limit. With P-5 module

The only difference is: In P-5 mode, when the timer is set to exceed the upper voltage limit, the relay will be closed when the voltage is lower than the lower limit.

Set to start the timer below the lower voltage limit, then the relay will be closed when the voltage is higher than the upper limit. In simple terms, the initial relay in P-4 mode

In the release state, the P-5 mode relay is initially in the pull-in state.

When the timer starts running, you can short press the ENTER key to view the countdown time.

The setting method and parameters of P-5 mode are completely consistent with those of P-4 mode. You can set the control logic and

Select normally closed point or normally open point to connect the load circuit.

If the time relay parameters are set in the “P-1” (timing relay) mode first, and then enter the “P-4” mode, the detection voltage will reach

When the set value is reached, the action will be executed in the "P-1" (timing relay) mode.

If the time relay parameters are set in the "P-2" (delay relay) mode first, and then enter the "P-4" mode, the detection voltage reaches

When setting the value, the action will be executed in the "P-2" (delay relay) mode.

Note: If the timing pull-in is started when the voltage is higher than the upper limit and the timing end relay is released, then the detection voltage must be lower than the lower limit and then higher than the upper limit to start the timing pull-in again. If the voltage is lower than the lower limit during the timing operation, timing The set value will be restored, and the timing will be reset when the voltage is higher than the upper limit. If it is set as the low and low limit start timing pull-in and the high limit relay is released, the timer works in the same way as the above, that is, the restart of the timer requires the detection voltage to exceed the upper and lower limits for one cycle.

Example of setting method:

1. It is required to connect the load for 5 minutes and then disconnect it when the detection voltage exceeds 14.5V, and disconnect the load when the voltage is lower than 11.5V.

Setting method: first enter the P-1 timer relay mode, set T1 to timer 5 minutes, T2 to 0, then exit P-1, enter P-4,

And set the upper limit of voltage to 14.5V, the lower limit of voltage to 11.5V, and the load is connected to the normally open point of the relay. Note: If the voltage exceeds the upper limit, start the order

After the second timer ends, the timer will start again for 5 minutes only when the voltage is lower than the lower limit and higher than the upper limit again.

If you want to disconnect the load when the voltage is higher than 14.5V, and when the voltage is lower than 11.5V, the load is connected for 5 minutes and then disconnected, you can press and hold the SET key for 3 seconds.

Reverse relay action logic.

2. It is required to delay 5 minutes after the detection voltage exceeds 14.5V before connecting the load. When the voltage is lower than 11.5V, the load is disconnected.

Setting method: first enter the P-2 delay relay mode, set T1 to 5 minutes, T2 to 0, then exit P-2, enter P-4,

And set the upper limit of voltage to 14.5V, the lower limit of voltage to 11.5V, and the load is connected to the normally open point of the relay.

3. When the detection voltage is lower than 11.5V, the load shall be disconnected after a delay of 5 minutes, and the load shall be connected when the voltage exceeds 14.5V.

Setting method 1: Enter P-1 timer relay mode, set T1 to timer for 5 minutes, T2 to 0, then exit P-1, enter P-5 mode, and set the upper limit of voltage to 14.5V and the lower limit of voltage to 11.5 V, the load is connected to the normally open point of the relay. Long press the SET button for 3 seconds to make the voltage lower than

Start the timer for a limited time, so that when the voltage is lower than the lower limit, it will start the timer for 5 minutes, and when the voltage is higher than the upper limit, it will be closed directly.

Setting method 2: Enter the P-2 delay relay mode, set T1 to timer for 5 minutes, T2 to 0, then exit P-2, enter P-4 mode, press the SET key for 3 seconds to make the voltage lower than the lower limit Start the timer and set the upper limit of voltage to 14.5V, the lower limit of voltage to 11.5V, and the load is connected

It is at the normally closed point of the relay, so that when the voltage exceeds 14.5V, the relay is released and the load will be connected. When the voltage is lower than 11.5V, the delay timer

Start, after a delay of 5 minutes, the relay will be closed, and the load connected to the normally closed point will be disconnected.

2.5 P-6 Voltage Over Limit Action Mode In P-6 mode, the detection voltage can be set to release within the upper and lower limits, and the relay will be closed when the voltage exceeds the upper and lower limits. Press and hold the SET key for three seconds to release

On, it can be switched to the voltage pull-in within the upper and lower limits, and release when the voltage exceeds the upper and lower limits (ie, P-3 mode is one-way pull-in, and P-6 mode is two-way pull-in).

Short press the SET key to set the upper and lower limits of the voltage and the correction value. The setting method is the same as in section 2.3.

2.6 P-7 voltage over-limit control time relay In P-7 mode, it can be set to detect that the voltage is within the upper and lower limits and the relay keeps releasing. If the voltage exceeds the upper and lower limits, the time relay will start

Timer, start timing or delay mode, depending on whether the previously entered mode is "P-1 Timing Relay Mode" or "P-2 Delay Relay Mode"

Type", the timer executes the relay release (when the time relay is set to pull in and release infinite loop, it will always execute, only when the detection voltage is

It will stop only within the upper and lower limits), press and hold the SET key for three seconds to release, and the voltage can be switched to release when the voltage is within the upper and lower limits.

2.7 P-8 digital tube auto-off setting

The minimum standby current when the digital tube is off is 6mA/12V. Set to "d-0", it means that the digital tube is off for 0, that is always on, press SET

Set a delay of 1 to 9 minutes by pressing the key. In any mode, the digital tube will automatically turn off when there is no key operation, and the digital tube will light up when there is a key operation.
