Instruction 3015-4286
DIAGNOS
– Enters the diagnostic function. Press the Up Arrow Keypad
button to toggle between the monitor’s two diagnostic screens. Refer to The
DIAGNOS Function (Page 21).
GASTYPE
– Ammonia monitors do not have a library of other gases to
choose from, therefore R717 is the only gas type listed. Press QUIT to return
to the previous screen.
LEAKLVL
– Sets the Leak Alarm level, adjustable from 1 to 300 ppm.
Factory default is 100 ppm. Note that 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.
SPILLLVL
– Sets the Spill Alarm level, adjustable from no lower than the
Leak Alarm level to a maximum value of 500 ppm, but not higher than the
Evacuate Alarm level. Factory default is 300 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 9999 ppm. Factory default is 500 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 10 minutes. Note that 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.
LOOP
– Adjusts the loop factor of the 4–20 mA current loop. Factory 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.
AUDALRM
– Allows the monitor’s internal audible alarm to be associated
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
NOTE: MONITOR STOPPED indicates there is a critical system fault, and the
monitor is no longer functioning correctly.
