Hello All,

Can anyone tell me how to change circuit A & B lead lag operation. I have the manual and have tried everything. Can anyone let me know if I am dumb as a bag of hammers or have I a problem.

Cheers

Hi CuGe:)
sorry little experience with this plant, but you need the controller manual and the sytem pass word to change the lead lag.

Try putting the first circuits compressors off on service, the second set will take the load and then put the first set back on line after this.

Still think U need the manual:D

Kind Regards. Andy:)

Try this link -
http://www.carrier.com.lb/products/Control_Systems/prodiagxhx.htm
and click on the Technical Information link at the bottom right of the screen; this will give you access to the Pro-Logic manual as a pdf download (4.32mb).

I think it is around page 24 that it gives the configuration instructions to change the lead/lag of the machine.

Hope this helps.

if it is a pd4 (white) -> user1 menu -> item 1 ->

0 means - automatic
1 means - lead A
2 means - lead B
------------------------
if earlier (black) -> configuration menu -> intem 2

0 means - automatic
1 means - lead A
2 means - lead B
(same as above)

you can reach these menus only if the unit is LOFF mode.
