PROCESSOR MODULE
The Processor Module, color-coded violet, occupies position 2. This module contains the
microprocessor which runs all the programs stored in the Feature Module (see page 8) of the
MERLIN system.
Switches A through H: Each switch on
the Processor Module aligns with a label
on the Feature Module in position 3 when
both modules are in place. The function of
each switch is indicated by the
corresponding label on the Feature
Module. (Refer to the Administration
Manual: Models 1030 and 3070 associated
with the Feature Module for specific
information about the switches.)
Warning light (red): When power is
turned on, the warning light goes on briefly
(while the module runs certain internal
diagnostics) and then goes out. It remains
on if there is a problem with the control
unit, for example, if a module is not
completely plugged in. It goes on again if
a problem occurs while the system is
running.
