Controller-User-Manual_2.png)Warning

1. Check the terminal number when wiring. Incorrect wiring can lead to controller failure and malfunction. Please check the terminal number before wiring.
2. Make sure that no excessive force is applied to the lead wires. Broken lead wires will result if bending stresses or tensile forces are applied to the lead wires.
3. Check the insulation of the wiring.
   Avoid defective insulation (crossed lines with other circuit, ground fault, defective insulation between terminals, etc.) with the wiring. Excessive current can flow through the controller,
   which may cause damage.

Operating Environment

1. Do not use in an atmosphere containing corrosive gases, chemicals,

sea water, water, steam, or where there is direct contact with any of these.

This may cause rust and/or corrosion on metal parts and deterioration of resin parts.

2. Do not use in environments where Areas where the product may be

exposed to particles or dust.

This may cause burnout of electrical parts such as short circuits on the terminal block.

3.Avoid direct sunlight or ultraviolet ray.

It may break/ damage the resin parts.

4.  Do not use in potentially explosive environments.

It must not be used in an environment with explosive gases, as there is a possibility of explosion.

5. Do not mount the product in locations where it is exposed to radiant

heat or other excessive heat.

It may lead to damage or malfunction of the board or element.

6.  Do not store in a strong magnetic field atmosphere.

This may cause electrical components such as transistors to malfunction.

7.  Do not operate in a location subject to vibration or impact.

It may lead to damage or malfunction of the board or element.

   ※The above 1) to 3) can be changed even after power is on, but time cannot be set during operation. Changes are enabled from the next ON or OFF time.
   

①Normal output （OFFt≠0）

6. Cascade connection

There are only outputs up to 10 points (6 points in the case of VXFC06A) on a single board.
However, it is possible to increase the output points by cascading (multiple board connection).
VXFC06A and VXFC10A can be cascaded to create a 16-point output, and it is possible to increase to any output points by combining boards.
Ⅰ. Connection method

1.  In the case of no cascading connection (operation of single unit)
   Do not connect anything either to the input or output terminal block.

2. When connecting 2 Boards in cascade
   ① Set the DIP switch for cascading with one board as base and the other as remote.
   ②Connect the OUT1 of the base board to IN1 of the remote board and OUT2 of the
   base board to IN2 of the remote board.
   ③ Connect OUT1 of the remote board to IN1 of the base board and OUT2 of the remote
   board to IN2 of the base board.

3. In case of cascading 3 or more boards
   ① Set only one DIP switch for cascading to base, and configure other boards to the remote.
   ②Connect the OUT1 of the base board to IN1 of the remote board(1) and OUT2 of the base board to IN2 of the remote board(1).
   ③ Connect OUT1 of the remote board(1) to IN1 of the base board(2) and OUT2 of the remote board(1) to IN2 of the base board(2). In the same way, connect the remote board 3, 4 …n.
   ④ Connect OUT1 of the remote board(n) to IN1 of the base board and OUT2 of the remote board(n) to IN2 of the base board.
   

II. Setting of the DIP switch for cascading

1. DIP switch setting
   For a cascading connection, set the board that operates first to the base.
   Boards connected after the base are set as remote

7-3 Sequence when temporary stop is operating

1） Operation sequence

The sequence of a temporary stop is shown below.
When the Switch is turned ON the temporary stop operation begins.
When the switch is turned OFF the operation stops.
Operation starts from the next output when the switch is ON again.
When the switch is turned OFF during the output, the operation stops after completing the output, and the operation stops until it is in the ON status.
If the power is OFF during operation is stopped, the status returns to the initial status
