SECTION 4 - Description of the CR192 Micro-starting
and Protection Module
light cannot be reset to green by depressing the recessed
pushbutton on top of the case, then the unit should be
replaced. Momentary flashes of red, particularly during power
up initialization, are normal and should be ignored.
4.4 Non-volatile, set-point
memory
The CR192 /lSPM contains an electronically-alterable, read-
only-memory (EAROM) to retain set-point parameters through
periods of power outage without the use of a battery storage.
Also if the /lSPM is stored or left idle for long periods of time, its
set-points do not have to be re-entered prior to placing the unit
back in service.

4.5 Readout of module
temperature
The CR192 can display its internal temperature in
degrees Celsius. To display the internal temperature press
"SHIFT" then the "4" key. The internal temperature of the
IlSPM will be displayed. Press any key to return the display to
normal. The temperature may be displayed while the motor is
running or stopped.
4.6 Circuit board conformal
coating
All of the printed circuit boards are now conform ally
coated to help protect the board, the components, and the
soldered connections from moisture, dust, and common
atmospheric contaminants.
