time, the content of the “Serial Number” position is in reverse display. At
this time, you can press the “PAGE” key/up key/down key to change the member
object to be edited currently.
Note:
The number of total members smaller than or equals to 10, page jump is 1 the
number of total members bigger than 10, page jump is 10
Editing interface of basic parameters
The basic parameters include “port No./hour/minute/second” In the 3.4.1
interface, press the left/right key to switch to the basic parameter editing
state of the current item. After entering this state, you can use the up
key/down key/rotary encoder to modify the corresponding parameters.
After editing the parameter “port No. /hour/minute/second”, press the “ENTER” key to return to the item editing interface. At this time, the changed information of the item is temporarily stored in the RAM memory area. Meanwhile, you can continue to edit other items through “Page key /Up key/Down key/Rotary encoder”. When all the items are edited and then press the “ENTER” key in the item editing interface to return to the main interface, the editing parameters of all items are saved in the ferroelectric memory.
Note:
If you press the “HOME” key to return to the main interface after editing all
items, the editing parameters of all items are only saved in the RAM memory
area, not in the ferroelectric or FLASH memory. Under the condition of
uninterrupted power restart, it can run according to the latest edited
parameters. After power off then restart, it will run according to the last
parameters saved in the ferroelectric memory.
Editing interface of the total cycle index
In the editing interface of 3.4.1 / 3.4.2, if you press the “EDIT” key again,
you will enter the editing interface of the total number of cycles.
After entering this state, you can use the up key/down key/rotary encoder to modify the corresponding parameters. Long press and hold the up/down key to quickly change the total number of cycles. After editing, press the “ENTER” key to return to the item editing interface. At this time, the changed information of the total number of cycles has been saved in the ferroelectric memory.

adding items.
At this time, the left/right keys can be used to select “Cancel”/”Previous”/”Next”. Select “CANCEL” (CANCEL) and press the “ENTER” key to exit the operation of adding items. Select ” PREV ” (PREV) and press the “ENTER” key to add an item in the previous position of the current item. The original current item and all subsequent items are moved back by one item. Select “NEXT” and press the “ENTER” key to add an item to the next position of the current item. All items after the original current item are moved back by one item position.
Operation of deleting items
In the 3.4.1 editing interface, press the “DEL” key to enter the operation of
deleting items.
At this time, the left/right keys can be used to select “Cancel”/” Delete”.
Select “CANCEL” (CANCEL) and press the “ENTER” key to exit the operation of
deleting items.
Select “DELETE” and press “ENTER” to delete the current item, and all items after the original current item are moved forward by one item. The total number of members is reduced by 1. When the current total number of members is 1, that is, when M001 is displayed, the deletion cannot be continued.
Running Operation
Start the control flow
In the 3.2 main interface, press the “ON/OFF” key to start the switching valve
control flow.
After the port switching is over, “Hole position is being held” is displayed
.
Countdown starts from the pre-set holding time, once the countdown reaches 0,
it will automatically switch to the port of the next item. If the preset port
No. exceeds the maximum port No., an error will be reported and the countdown
will be valid.
When the current cycle is over, it will automatically switch to the next cycle. When all cycles are over, the control flow ends.
Pause the control flow
During the start of the control flow, when the port position is hold (Hole
Keep), if the “ON/OFF” key is pressed, the control flow is suspended. During
the switching of port Hole Conversion), the pause operation is invalid
.
After the control flow is suspended, it will only be restarted after manual intervention.
Manual reset operation
In the pause state, you can press the “Reset” (RESET) button to perform manual
reset operations.
Note:
Prompt “Manual Reset”, the reset operation is in processing; Prompt “Hole
Reset & Pause”, the reset operation has been completed at this time; it is not
the port position indicated by the current item. Press （ON/OFF）again can
automatically switch to the hole position of current item
Automatic reset operation
During the process, if the programmed port position is set to 0, when the item
is executed, the “automatic reset” operation will be executed.
When the automatic reset operation is completed, the port/hole position is
maintained according to the setting time.
When the countdown set according to the control flow finished, proceed to the next item.
End of Cycle
When the total number of cycles is executed, the cycle operation ends
automatically.
If the total number of cycles is 0000, it is regarded as an infinite cycle.
Bridge Operation Mode
In special circumstances, when RS485 communication is required to control
internal or external switching valves, bridge operation mode is needed.
Set to RS485 communication control mode
Press “right key” to turn on, switch to RS485 communication control mode.
RS485 bridges internal switching valve
To use the plug-in mode to control the built-in switching valve, you need to
bridge the pins 4-pin 12 and pin 5-pin11 of the DB15 respectively.
RS485 bridges external switching valve
To use the plug-in mode to control the external switching valve (Note: the
switching valve needs to be RUNZE protocol), you need to connect the external
RS485 interface (DB15-4 pin is B, DB15-5 pin is A) with the external RS485
device respectively.
Equipment Maintenance
Common Equipment Maintenance Process
Regular maintenance of the valve core
When not in use for a long time, please empty the liquid in the valve core of
the switching valve in time. Prevent the liquid from staying in the valve core
for a long time and corrode the rotor plane.
Rotate the rotor regularly
When not in use for a long time, usually regularly (about 7 days), rotate the
switching valve to prevent sticking due to residual liquid.
