Instruction 3015-4256 17
SILENCE – Used to enter a length of time for which the internal audible
alarm and the external alarm are turned OFF when the front panel SILENCE
button is pressed. The factory default is 300 seconds (5 minutes). If the
cause of the alarm/fault has not been cleared at the end of this time period,
the internal audible alarm and the external alarm device are reactivated. Use
the Keypad to enter the desired time period, and then press ENTER to save
that value and return to the previous screen.
SQUELCH – Sets a value of between 0.0 and 99.9 ppm that prevents the
display of measurements below that value. Factory default is 0 ppm. For
example, if the squelch setting is set to 50 ppm, then the monitor will not
display measurements that are below that value. Use the Keypad to enter
the desired value, and then press ENTER to save that value and return to the
previous screen.
ZONETEMP – Used to enter the temperature of the area being monitored
in °C, thus giving a more accurate ppm reading. The factory default is 25°C.
Use the Keypad to enter the desired temperature, and then press ENTER to
save that value and return to the previous screen.
CAL – Used to change the monitor’s calibration factor. This function is to be
used ONLY with instructions from a Bacharach Service Center. Factory
default is 1.000.
P-CHK – This Pressure Check function displays the current manifold
pressure and the stored ambient pressure in psia, along with the difference
between these two pressures and the current fault code.
