The REPEAT mode continues to cycle through the SELF-TEST sequence until terminated
by the operator. When in REPEAT mode, the DISPLAY and KEYPAD self-tests are only
performed during the first cycle and are skipped thereafter. In REPEAT mode, the
display indicates the number of successful passes through the self-test cycle. If an
error occurs while in REPEAT mode, the self-test will stop and the display will flash and
indicate the nature of the error and the cycle-number during which the error occurred,
as shown below:
NVRAM FAILURE
PASS COUNT = 3
RAM FAILURE
PASS COUNT = 3
COMM PORT FAIL
PASS COUNT = 3
BATTERY FAILURE
PASS COUNT = 3
The operator may record the error and continue the REPEAT mode by pressing the
ENTER
key. At the end of each cycle, the user is given the option to exit the REPEAT
mode by pressing the
ENTER
key. This capability is indicated on the display as shown
below:
PRESS ENTER TO STOP
PASS COUNT = 21
Normal sensor data-processing is interrupted when in the self-test mode, therefore it
is recommended that the use of the REPEAT mode be limited to isolating a suspected
problem area by testing it multiple times. Once the problem had been investigated or
confirmed, press
ENTER
to exit the SELF-TEST REPEAT mode.

Sensor Check
The Chloralert™ Plus includes an optional SENSOR CHECK feature that may be used to verify
the integrity of the sensor and its associated electronics. This check may only be performed on
channels that have been configured with the optional sensor check gas generator (refer to Parts
Lists 325.7603). The channels on which the check will be run must be selected by making the
appropriate entry in the last four digits of the configuration code (refer to section 3.2.2.9.2).
NOTE
In order for the SENSOR CHECK to function properly, the sensor
CHANNEL must contain the optional SENSOR CHECK gas generator and the
channel entries in the CONFIGURATION CODE must correspond to the
channels on the sensor interface terminal block (TB3) to which the
sensors are wired. For example, if a single-sensor system has its
sensor wired to S3+ and S3- on TB2, then the “
1
” entry
in the CONFIGURATION
CODE must be placed in the
“CH3”
position, otherwise an error will result.
The ten minute test consists of generating a test gas using the sensor check gas generator and
detecting the gas with the sensor. If the generated test-gas is detected within a certain concentration
range, the test is considered successful and the unit will automatically revert to the RUN mode. The
sensor check test is valid whenever the background concentration exceeds 0.5 ppm.
