MK electronic time lag switch

[lilman]

Evening all. I'm after some instructions for MK 1610 electronic time lag switches - can't find any info anywhere. A customer of mine has installed some in communal areas and they don't seem to be working properly. Anyone got user guide or other helpful diagrams/info?

Only have data on older version . Must be the same principle. Its a N/O timer module that switches when one of the non latching switches is pressed on the stairs , check there is a voltage when switched, check there is L&N feed and L&N output when its triggered. This will sound daft but I know someone who fell for this, check that the tenants have nicked all the lamps from the fittings.

I've just realised that all 3 time lag switches are master units - and they are controlling a single 60W lamp. The minimum loading of the master units says 60W. I presume the load is too small; either need capacitors somewhere in the circuit or 1 master and 2 slave units. Does this sound about right?

I think 2 need to be slave units, in order to operate correctly.....?????

I saw that link but didn't click further as I presumed it was some MK marketing type brochure link or something similar. Good work DaveyGH
