Demand control is available by connecting remote switches with termi-
nal No.10 - 14.
Make sure to use the non-voltage switch (for the remote switch).
Remote switch cable length : Maximum 10m
Remote switch : Minimum applicable load DC12V, 1mA
• 4-20mA / 1-5V / 0-10V / 0-10kΩ
1 Use 4-20mA / 1-5V / 0-10V
Connect the transmission cables to No. 3 and 4 on the terminal
block (TB62).
No. 3 on the terminal block(TB62) : Plus side
No. 4 on the terminal block(TB62) : Minus side (Reference side)
2 Use adjustable resistor (0-10kΩ)
Connect the transmission cables to No. 1 and 2 on the terminal
block (TB62).
