Why wont the 753SSR sensor turn off the lights, it is wired to a contactor?

Even though this is a 3 wire device it still has leakage current and enough to keep the contactor energised therefore your lights will remain on. The way to prevent this is to use a 31CAP in parralell with the load. This will provide an alternate path to neutral.

I have 2 wire 31VETR and i dont have enough load will a 31CAP do the trick?

It will improve the situation however we cannot confirm wether it will fix the problem or not. The alternative is to use the three wire design 31VETR3

Where should the Load correction devices 31CAP and S31LCDA be used?

The 31CAP is to be use with the following two wire products
Infrascan 750WP, 751, 753.
Timer 31VETR
Sunset Switch WS226SSR/2, 56SSR/2, 31VSSR/2

The S31LCDA is suitable for use with Clipsal & Schneider Electric 2-Wire, mains powered Dimmers that use
Leading Edge, Trailing Edge and Universal Dimming.
Other Suitable loads: Dimmable CFL/ Dimmable LED with Electronic control

(Load correction Devices may not correct all problems)
Installation Instructions can be found on the Website.

Can you use the 31CAP on a Leading Edge Dimmer?

No, the Leading Edge dimmer has a maximum input capacitance of 300nf, you would be able to use the 31LCDA as an alternative.
Trailing Edge and C-Bus Universal dimmers do not have a capacitance limit and either can be used.

What is the rating of the 31CAP?

The rating of the 31CAP is 10nF (Nanofarads).


What is the difference between the 31Cap and 31LCDA?

The 31CAP is a load correction device which consists of a "Capacitor only" to help 2 wire products achieve minimum load levels. The 31LCDA has circuitry built in to the device to enable it to correct minor compatibility issues found between dimmers and LED lights for example slight flickering when dimmed at a higher level.

31CAP - Increases minimum load.
