VL12

[Gladwin]

Good day,

Hope you are well.

Is it possible use the input on a VL12 can be set to switch off the system when the site is running on a generator.

I have check on the user guide.  I saw these below, not sure if can be used to turn off all the capacitors.

“Switching on Cos φ2 via Digital Input

or P Export

If a dry contact is connected to the digital input terminal, the controller will

switch to Cos φ2 and display "NT."

• Connected output dry contact between terminal I1, I2. Voltage source

internally supplied: 5 V DC - 10 mA. Recommended section ≥ 1 mm².

Length of cable should be less than 100 m.

• Set item 510 in advanced menu:

- Yes = digital input is activated with closed terminals I1 & I2

- No = digital input is activated with open terminals I1 & I2.

• Set Cos φ2 target in 303.

Also, the controller is able to switch to Cos φ2 when P EXPORT is detected

(from load to grid)

• Set item 504:

- Yes = the controller operates in P-export with the Cos φ2 as control target.

- No = the controller operates in P-export with the Cos φ1.”

Yes, when operating on the generator on site, the digital input on VL12 can be used to switch to "Cos φ 2" to turn off all capacitors. Cos φ 2 can be set very low, so there is no need to open all capacitors.

switch to Cos φ2 and display "NT."
