I recently purchased some Voltek security light equipment from you, and I am trying to connect it up, but I am stuggling with the Securilite TZX 1819 Command Centre. The wiring diagram shows to connect the 1812 unit to the 1819 unit as + to +, - to -, S1 to S1 etc. Although the 1812 unit is clearly labelled, there is no indication on the 7 screw terminals on the 1819 unit which terminal is +, which is - etc.

Do you have any ideas?

There should be a label on the unit? but either has fallen of or was not put on. Apologies.

 

As you look at the back of the unit starting from the left the connections start + - S1 R1 S2 R2

if i recall those connections are marked on the pcb during manufacture. But you wont find the other end having s1 s2 etc as they will only have s.
