DEIF DELOMATIC SCM-1 POS 1044220100F Synchronizing Module The SCM-1 module consists of three boards connected by an eight wired bus on the front side (not the backplane bus). The boards for SCM-1 are named SCM-A, SCM-B and SCM-C and these names can be found on the boards. 

SCM-A board:

 Two relay-boards OPR-1 can be mounted.

 One for output for a mechanical speed governor (instead of electronic speed governor), and one

for outputs for mechanical voltage regulation (instead of electronic voltage regulation).For replacement of OPR-1 the screw for holding SCM-A must be removed, replace the OPR-1

modules, mount SCM-A ag

SCM-B board:

 DIP switches:

 The I/O address for the backplane bus of the rack is to be set. Notices that all SCM-1, SCM-2 and

PRM-1 modules must have different I/O addresses starting with number zero (null) and up to two.

The number sequence can be interrupted. The I/O address is set by the S2 switch. 

SCM-C board:

 DIP switches:

 The voltage measuring range is selected by jumpers on this board.

 For generator voltage the measuring range is selected by jumpers X5, X6, X7 and X8 and for the

busbar voltage the measuring range is selected by jumpers X10, X11, X12 and X13 (one jumper

for each phase and the 0-conductor.
