Programmer Connector





Terminal Functions

Terminals 4, 6, 9 and 10 form a multiplex electrical information connection with the control panel head. The programmer receives its operating information (commands) in the form of square electrical waves from the control panel head. These signals cannot be measured accurately with normal shop equipment. If a problem is suspected with the programmer:

^ Check wires from terminals 4, 6, 9 and 11 for continuity with control panel head connections
^ Check terminals 1, 11, 5, 8 and 12 on programmer (see chart)
^ Check for proper output signals from control panel head channel 7.


If all of these are OK, replace programmer.
