Hi There,

I have an old Horizontal Bridgeport machine with power feed. The machine was made in Leichester England and the sequence control panel was built by Saunders Electronics Limited.

The X-axis limit switch box was connected wrongly, therefore the machine won't come on. There are 11 wires that I do not know where to put - wires are numbered as follows:

185, 186, 187, 188, 189, 190, 56, 20, 11, 12, 159, 17

I opened the y-axis and z-axis limit switch boxes and wires were connected as follows:

Y-axis:
21-20 normally closed - Hard limit
51-50 normally closed
50-41 normally closed

Z-axis:
21-22 normally closed - Hard limit
51-52 normally closed
52-46 normally closed

I assume that the x-axis should be :

185-186 normally closed
187-188 normally closed
189-190 normally closed

wires 17 and 159 is connected to the emergency stop (17 comes from the machine and does not connect to the limit switch box - where 159 has to connect there somewhere.

The emergency stop switch is normally closed and when I activate the contactor it has 110V to ground.

When the contactor is activated 185-186 has 110V to ground.

This leaves me with wires"

56
20
11
12
159

Could you please help me....I need this machine running.

Kind Regards.

John
