Fluorescent Light with 4 Terminals

[collins3248]

I have a Flu light to fit and the incoming mains terminal has a 4 terminal block connector with L, N, E and a N/v terminal the Nv wire is blue and white and goes to the ballast. should the mains neutral be connected to the N or N/v

Is it a dimming ballast? Is there a diagram on the side of it? If so, can you post a piccy?

is there a make and model no, on the ballast.
Not seen N/v terminal before

Have seen dimming ballasts where you fit a variable resistor across 2 terminals, an open circuit or high resistance across the terminals in the cases I know of are required for full brightness.

Thanks for that quick response I'll take the cover off in the morn and post a pic.

Its a 702mm Cryselco Proteus single PDX1218

Crystelco, what range, model number?

Is it a fitting with emergency lighting capability?

 

[collins3248]

The ballast is a Vossloh Schwabe no 922428, just to add to the confusion I have 2 of these lights and just taken the cover off the other, this also has a 4 terminal block but is labeled L/v, L/f, E, and N but this time the L/v goes to the ballast.

The ballast is a Vossloh Schwabe no 922428,

not one I know , V/s units normally have a wiring diagram stamped on the unit.

It may be a unit made to connect to a remotely fitted emergency pack.
Usually you can addapt the fitting to work on its own though

I think it's a 0-10V or PUSH dimmable light.. depends on what the balast says..

you either use a 0-10v dimmer to dim them, or you have a momentary switch instead of a regular light switch..
push for on, hold to dim, push again for off...
