Motek H2H and Gibertini 1.5 install.

I sprayed mine with a special outdoor paint, it saved the need for rubbing down, but worked out a bit more expensive.

Looks like I didn't connect the sensors wires to the right terminals. Not a major problem, just another job

... Talking about wires Chris, and by all means tell me to do one if you feel inclined, it's the telephone cable i see for motor + sensor duty. I'm a tad concerned about volt drop at the motor terminals especially when you move the dish from standstill or from an extreme end of the arc. Initial current drawn by the motor will be briefly higher at start-up but will have an impact on the volt drop and hence the final supplied voltage at the motor terminals .... which might give you a problem. Also because of the very small gauge on the sensor wires the pulses at the rig end might be affected a tad and give erratic pulse counting on the E-W controller. Not sure what your cable run length is also Chris, but long runs with that phone cable will make things worse. And finally --- don't like the knot in the cable lol.
Crack on though, good to see you making progress with the install.

Agree with John here, some 4 core mains cable would be better here. The outer sheath of phone cable you are using looks to be internal stuff, and perishes quite quickly in UV light, starts to powder...

I use 4 core mains cable with 1 millimetre diameter per copper core, I think it was rated at 10 amp but would need to check. It was definitely 1 milimetre per copper core though, I made a point of getting that diameter.

Update:

Just checked my last purchase, it was 10 amp rated cable with 5 x 1 millimetre cores, individually sleeved, all enclosed in a rubber outer sleeve. The rubber outer sleeve is better for outdoor use compared to a PVC outer sleeve.

Will this stuff be suitable?

I guess that's what's causing my actuator/v-box to miscount, decided to move my v-box to the garage and run some new cable.

I will have to use the telephone cable for now, while I get some proper stuff.

Cheers @John @scopus & @moonbase some very useful comments

That will do nicely Chris, i use the same stuff on one of my runs. The really good stuff that has 2 x larger conductors for the motor and two smaller shielded conductors for the pulse count sensor is as rare as rocking horse poo these days.

I use a cheapo 8-core alarm cable and join two of the internal wires together for both sensor and motor. As it runs through a plastic conduit, it's not affected by UV light and general elements.

John,

I am not sure if the real good stuff with the shielded pulse/sensor conductors is available anymore in the UK? I took some long lengths of it from old flat triple ribbon cable that was used on motorised installs but I have not seen anyone sell it for years.

Yeah shame really D, i have only the one run of the good stuff and that was from a system i bought in about 1986 ish time

I was getting pulse miscounts, as the positioner/actuator never put the dish in the same place no mater where it was on the arc.

Sounds daft, but I am finally glad as I now have a possible answer as to what was causing it.

I will move the positioner into the garage and drill a hole through the single skin brick wall.

Still have a few little jobs I have to sort first, the main one being that dent, caused by a bolt thread, a hacksaw should sort the bolt.

The rubber mallet, might need a trip into town.

I use this from Yesss Electrical, it can be bought by the mtr.

I have some of that flat cable at home. It came as part of Greg 90cm win on EBay, motor, pulse, polariser and co-ax all in one. Good quality, but not long enough for my cable run unfortunately.

drats,

Thats the cable, I use the 5 core equivalent for actuators with an optical switch.
