1.8 Verifying System Response

The verification routine checks the operating condition
of the SPM optical system through use of the optical test
card supplied with the instrument. The instrument must
be in Monitor Mode to start this test, and if the unit has
the ChemKey option, the ChemKey must be installed
and turned on.
Perform the verification routine as follows:
1. Open the tape load lever (18). Remove the
Chemcassette
(17).
2. Press alarm test (10). The green system status
LED (9) will flash rapidly and the display will
show (VERIFY).
3. Insert the test card with position #1 centered in
the detector head (17). Be sure that the colored
chip on the test card faces up and that the card
is inserted fully into the detector head (17).
4. Close the tape load lever (18) and press alarm
test key (10). The audible alarm will emit one
short signal.
5. Open the tape load lever (18) and reverse the
test card, centering position #2 in the detector
head (17).
6. Close the tape load lever (18) and press alarm
test key (10).
7. If all electronics and optical systems are
operating properly, the instrument will simulate
an alarm condition and activate both the audible
and visual alarms. The 4-20 mA circuit will output
a signal of 10.1 mA to 13.2 mA.
Note:
Alarm relays will not activate during the verification
routine.

8. Open the tape load lever (18) and press alarm
reset (11). Replace the Chemcassette
re-thread the tape (7). After pressing the alarm
reset button, the alarm lamp (16) does not
extinguish. Wait until monitoring is resumed,
then press the alarm reset button again.
9. Close the tape load lever (18). The SPM will
automatically begin monitoring.
10. Press the alarm reset button to turn off the alarm
lamp (16).
11. Plug the end of sample line. A fault #17 will be
generated, indicating that there are no leaks
between the sampling point and SPM.

1.8.1 Improper System Response

If the system is not operating properly, the audible alarm
will signal two times and the red system status LED (12)
will light.
If this occurs, open tape load lever (18), press alarm
reset (11), ensure that the colored chips on the test card
are clean and repeat the verification procedure. If the
system still indicates a malfunction, contact Honeywell
Analytics Service for assistance.

1.8.2 Open Tape Load Lever Fault

An internal timer is activated when you open the tape
load lever (18) for the verification routine. If the lever is
not closed within two minutes, the:
• red system status LED (12) will flash
• audible alarm will sound
• green system status LED (9) also flashes
• SPM display will show (FAULT 25)
• instr ument fault relay is activated (de-
energized)
