Parameter
Description
Response Filtering
This parameter is used to turn filtered output ON
(01) or OFF (00).
The default setting is ON (01). The Modbus and
analog output are filtered so that responses below
75 ppm are squelched. If the display mode (P.-09)
is set to ON (01) the display shows 0 for any signal
level below 75 ppm.
Some installations may wish to monitor the small
analog output changes that may be created by the
detector environment. Turning filtering OFF (00)
allows these small variations around the minimum
analog output (e.g., 4 mA, 1V, etc.) to be
transmitted via Modbus and the analog output
terminals.
NOTE:
The detector display is OFF when filtering is
OFF (P.-09 is disabled).
NOTE:
Whenever filtering is OFF the detector
display will turn ON for 10 minutes if the detector is
re-zeroed (see Section 4.3). This is intended to aid
maintenance testing. The analog outputs continue
to transmit the full, unfiltered range, and the alarm
setpoint remains active.
NOTE:
If filtering is turned off (00), Analog Output
Scaling (P.-16) should be adjusted to 500 ppm.
5.3. Completing Setup
To complete the setup after all parameters are set as needed, simply
press and hold the information button (
L
) for 5 seconds to exit the
Parameter list. The gas detector is now actively monitoring its
surroundings.
NOTE:
If no buttons are pressed for 2 minutes, the
MGS-250 exits setup mode automatically.
