Addendum

Analyzer Alarms, Faults and
status
The 2200 series is equipped with alarms, fault detection and
sequencing (analyzer status) signals that may be mapped to
one or more of the four programmable relays. The relays allow
DRY (N.O.) normally open and (N.C.) normally closed
contacts. The relays may be set by the user to operate in
either Failsafe or Normal mode.
The following is list of Faults, Alarms and sequencing status
signals that can be assigned to the four programmable relays:

General Fault
Indicates that a fault was detected that can cause the system
to stop functioning or abort measurement cycles, this
includes loss of sample, fluidics fault signals from any of the
level sensors that may be assigned to reagents or standards,
optics failure or heater malfunction and when a unit fails to
execute a good calibration based on the parameters specified
by the user.

Fluidics Fault
Indicates that a fault was detected in one or more of the level
sensor inputs which may be assigned to reagents, standard
or sample.
Sample Loss
Indicates loss of sample was detected, the measurement
cycle is aborted when NO sample is present. (The sample
level sensor must be assigned to one of the level sensor
inputs (1-5), typically defaulted to input# 5 for this alarm to
function).
In the RUN mode (auto analysis) the system will continuously
monitor the SAMPLE LOSS signal and if the sample recovers
(becomes available) the system will wait for 1 minute to
validate the presence of the sample and to allow purging of
the sample chamber before restarting analysis.
Off Line
This alarm signal indicates that the unit is not running
Automatic Analysis.
Result Ready
Indicates end of sample measurement cycle and that data
can now be collected from the analog loops. In the Normal
mode, the assigned relay is deactivated at the beginning of a
new sample measurement cycle and activated at the end of
the measurement cycle before the post wash indicating that
sample analysis result data is now available on the analog
output.
The RESULT READY signal can operate in two timing
modes:
ACTIVE TIME: 060 sec (default setting)
The signal is activated at the end of the sample measurement
cycle and reset after the specified time. The limit is 900 sec.
