Overview
If the CADD‑Prizm
®
PCS II 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 activated as well as the amber
warning LED. An error message will be
displayed. On the next power up, the error
code will again be displayed 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.)
7 Hardware and Software Fault Detection
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 microprocessor.
