Overview
If the CADD-Prizm
®
pump displays an error
code, a hardware or software fault has been
detected by the microprocessor, and the pump
should be returned for servicing.
When hardware or software faults are detected
by the microprocessor, pump operation stops
and a continuous, audible alarm will be acti-
vated as well as the amber warning LED. An
error message will be displayed. On the next
power up, the error code will again be dis-
played with the software level (see illustration
below). If the error detected was a data fault,
the pump will be in Lock Level 2, and all other
programmed functions will have default
values. (See the pump’s Operator’s Manual for
specific defaults.)

Order of Error Code Events
1. There is a continuous two-tone audible
alarm, a continuous amber indicator light,
and the display will read
NOTE:
“XXXXX” is a 5-digit code.
2. To silence the error code alarm, remove the
battery.
3. At the next power-up, the last error code
(lec) will be visible on the display. The
microprocessor will also record an error
code in the Event Log. The description
“Error Detected” along with five digits will
appear in the LCD in the Event Log. These
five digits will remain in memory and will
appear on the Event Log record until 500
data writes have occurred or until the mode
has been changed. (See “Testing Procedures”
starting on page 23 of this manual for
detailed instructions regarding the power-up
check.) Thus, there is always a record of the
last internal fault detected by the micropro-
cessor.
