Has anyone fitted one of these? The instruction sheet has disappeared. Just need to know which terminals to connect the float switch to.[ElectriciansForums.net] Marsh Industries MA1 high level alarm [ElectriciansForums.net] Marsh Industries MA1 high level alarm [ElectriciansForums.net] Marsh Industries MA1 high level alarm

[ElectriciansForums.net] Marsh Industries MA1 high level alarm Thanks Tel. Plug connections are Com, I/P 1, I/P 2. The black wire from 0v on pcb is connected to I/P 1.
I'll do a bit of trial and error. Logic would suggest Com and I/P 1.......
 
That hard wired connections looks a bit of a bodge. Was it supplied like that?
 
Yep, the mains flex on left, small black to the middle connector and the relay output to the beacon are all original.
 
Doesn't look like any strain relief on that mains cable either. Jeez I do moan a lot me.
 
I have to admit to removing the flex gland as it is mounted on trunking.
I connected the float switch accross Com and I/P 2, pulled the float from the chamber and the alarm went off.
Thanks, everyone.
