Bacharach Halogen Monitor Instruction page 15

DIAGNOS – Enters the diagnostic function. Refer to Section 3.12.
GAS TYPE – Displays refrigerant gas as the gas being monitored. No other
gas types are available for selection.
LEAKLVL/RANGE – Sets the Leak Alarm level, adjustable from 1 to 1999
ppm. Factory default is 500 ppm. The Leak Alarm level cannot be set higher
than either the Spill or Evacuate Alarm levels. Use the Keypad to set the
desired Leak Alarm level, and then press ENTER to save that level and return
to the previous screen.
When the LEAK DETECTOR option is set in AUDALRM the user menu will
display the word RANGE in place of the word LEAKLVL. Adjust the value to
correspond to the maximum concentration to be detected. The instrument
will beep and blink the ALARM light proportional to the gas concentration
present.
SPILLLVL – Sets the Spill Alarm level, adjustable from no lower than the
Leak Alarm level to a maximum value of 1999 ppm, but not higher than the
Evacuate Alarm level. Factory default is 700 ppm. Use the Keypad to set
the desired Spill Alarm level, and then press ENTER to save that level and
return to the previous screen.
EVACLVL – Sets the Evacuate Alarm level, adjustable from no lower than
the Spill Alarm level to 1999 ppm. Factory default is 1000 ppm. Use the
Keypad to set the desired spill level alarm level, and then press ENTER to
save that level and return to the previous screen.
LOG INT – Sets the interval at which measurements are logged to
memory from 1 to 9999 minutes. Factory default is 1 minute. The logged
measurements can be viewed using the PPM LOG function. Use the Keypad
to enter the desired value, and then press ENTER to save that value and
return to the previous screen.
Adjusts the loop factor of the 4-20 mA current loop. Factory
–
LOOP
default is 0.016 mA per ppm, which provides an output range of 0 ppm
(4 mA) to 1,000 ppm (20 mA). Use the Keypad to set the desired loop
factor, and then press ENTER to save that value and return to the previous
screen.
To facilitate loop zero and span checking, note that when the LOOP function
is selected the loop output is set to 20 mA, and upon exiting this function
the loop output is set to 4 mA.
Allows the monitor's internal audible alarm to be associated
–
AUDALRM
with any function of the monitoring system. Factory default is OFF. Use the
Keypad to select the desired audible alarm function, and then press ENTER
to save that value and return to the previous screen.
Audible Alarm Settings: OFF, ANY ALARM, SYSTEM FAULT, LEAK ALARM,
SPILL ALARM, EVAC ALARM, MONITOR STOPPED, LEAK DETECTOR.
NOTE: MONITOR STOPPED indicates there is a critical system fault, and the
monitor is no longer functioning correctly.
