finding a suitable off delay for the VFD contactor AT THE RIGHT PRICE is proving a challenge right now. There are some cheap ON delays which could be used but would not be fail safe.

Excellent doc eddy, spot on. Also very handy as it details hooking up a AB msr138dp which I have just bought on ebay for £30! After looking into the specs there are 10 different varieties (various voltages/delay ranges) and I think this is the right one/most useful (hope so, I've bought it now!) - 440R-M23143 (24v - 0.15 - 3 seconds delay)?

Also, I spoke to the guy and he said he has another which he is willing to sell for the same price. Let me know if you are interested eddy and I will pass on his number

Cheers.
