Satellite XT 4-20 mA Versions
4-20 mA Range
The 4-20 mA signal output range of the instrument is
preprogrammed to correspond to the nominal range of
the target gas. The 4-20 mA range may be adjusted to
individual requirements, but must not exceed the upper
and lower values listed in Section 8. Actuate the <set>
key to enter and display the actual setting.
<Actual 4-20 mA Range>
To change the value, use the cursor keys <left> or
<right> to reach the desired position. Use the cursor
keys <up> and <down> to select the figures you wish
to enter. After the new value has been entered, actuate
the <set> key to confirm or <esc> to exit.
Relays
Allows the user to enter or change various settings for
the internal relay contacts for Alarm 1, Alarm 2, and
Fault. Use the <set> key to enter.
! Note:
The RELAYS menu and all subsequent menu items
are only available for instruments with relay
option.
Relay State
Used to individually define the relays to be either
deenergized (normally open contact) or energized
(normally closed contact). Use the <set> key to enter
or continue in the menu with the cursor keys <up> or
<down>.
Alarm Delay
Used to set a delay for the relay activation in case of
concentration alarms.
Use the <set> key to enter or continue in the menu
with the cursor keys <up> or <down>.
Fault Trigger
Used to define the trigger conditions for activation of
the Fault Relay.
Use the <set> key to enter or continue in the menu
with the cursor keys <up> or <down>.
! Note:
Individual settings for alarm levels, gas name, and the 4-20 mA output range, will automatically
revert to the factory programmed settings, whenever a new sensor type with a part number
different from the part number of the sensor used before is installed.
