TS4000
4.6 Selectable Options
The TS4000 contains a number of user configurable options that can be selected using the
supplied magnet.
Figure 15: Selectable Options
4.6.1 Sensor Range
The Sensor Range is configured automatically by the TS4000 when a new electrochemical cell
is plugged into the Interface Module. The exceptions to this rule are specified below.
NOTE:
The sensor scale / type option is disabled when the Sensor Range is automatically
determined by the TS4000.
The Sensor Range for the following three sensor types is not uniquely determined by the
TS4000 and must be configured manually:
•
Carbon Monoxide (CO)
•
Ammonia (NH
3
)
•
Chlorine (Cl
2
)
For these three types, the Sensor Range must be set from the Base Unit, after the sensor is
plugged into the Interface Module. When a Carbon Monoxide (CO) sensor cell is installed, the
selectable ranges are either 100 ppm or 500 ppm Full Scale (FS). When an Ammonia (NH
3
)
sensor cell is installed the user may select either 50 ppm or 100 ppm FS. When a Chlorine (Cl
2
)
sensor cell is installed the user may select either 10 ppm or 20 ppm FS.
To Change the Sensor Range for CO, NH
3
and Cl
2
1. Apply and hold the magnet on the GM logo on the Base Unit cover. Wait until “
SE
” displays
and then remove the magnet. This action places the unit into Setup Mode, causing “
Sr
” to
be displayed immediately.
2. Apply and remove the magnet. Wait until “
CO
”, “
nH3
“ or “
CL2
” displays. Apply the magnet
once again to select and configure the TS4000 for the installed sensor type. The user will
then have the following sensor ranges to choose from (depending on the installed sensor):
•
“
CO
” –
100
and
500
•
“
nH3
“ –
50
and
100
•
“
CL2
“ –
10
and
20
3. Apply and remove the magnet to select the correct range.
4. Once the correct sensor range is selected, the unit returns to the Setup Menu and depicts
“
Lo
” on the display.
5. When
“
Fi
” displays again, apply and remove the magnet to exit the Setup Menu.
