Replacement of module SCM 4.2
The SCM 4.2 module consists of 2 cards connected by a wired bus on the front side (not the
backplane bus).
The card located to the left on the SCM 4.2 module is the same card as in the SCM 4.1 module.
For detailed information about this card, please refer to the SCM 4.1 module.
The card located to the right on the SCM 4.2 module is the EM (Engine Module).
Two relay boards, OPR-1, can be mounted:
• One for output for a mechanical speed governor (instead of an electronic speed governor)
• One for outputs for mechanical voltage regulation (instead of an electronic voltage
regulation)
These OPR-1 are only to be mounted, if binary interface to the governor/AVR is present. If
analogue interface is used, then remove these OPR-1 PCBs.
The OPR-1 can be replaced if needed. This is easily done, placing the module front down and
removing the screws. Before reinserting the module, check the interconnection between the two
PCBs (8-wire connection).
DEIF A/S reserves the right to change any of the above.
