1.3. Remote Controller
Options
The MRLDS can connect to any controller
through the standard analog output (voltage and
current; see Table 1-5 for options) such as the
standard alarm relay.
1.4. Parts List
Table 1-4 shows a list of components that are
available.
1.5. Specifications
For default values, refer to Section 5.2., Setting
Parameters.
1
When filtering is disabled (see parameter P.-19 in Section
5.2.2., Configuration Parameters), the unit will respond to con-
centrations sub-10 PPM.
Optional
Recalibra-
tion
(For
Improved
Accuracy)
By applying calibration gas containing the
new target refrigerant, and via the routine
described in Section 6.4., Adjustment Using
Calibration Gas, the gas detector may then be
adjusted to respond with the calibrated
accuracy as shown in Table 1-2 for the new
target refrigerant.
