Line End Filter
Assembly
275-0242 The gas-sample line filter and purge-line termination
filters prevent dust and dirt from entering the monitor.
Both of the filters should be periodically checked and
replaced when there are obvious signs of
contamination.
• A zone flow fault will occur (fault code <0800>) if the
gas-sample line filter becomes blocked
• A purge flow auto will occur (fault code <1000>) if
the purge-line filter becomes blocked.
Remove the filter from the line and replace it with a
new one.
Line End Filter 275-0315
End-of-Line
Water Stop
275-0315 The end-of-line water stops prevent contaminants and
moisture from entering the monitor. This filter should
be periodically checked and replaced when there are
obvious signs of contamination.
Water Trap 275-0234 The water trap removes moisture that enters tubing before
allowing it to enter the internal components of the RLDS
unit. The water trap should be emptied often as
condensate accumulates. The water trap filter should be
periodically checked and replaced when there are
obvious signs of contamination.
Fuses 275-0250 The RLDS is protected from electrical damage by two, 1A, 250 V, type “F”
fuses. Locate the fuse holders and carefully remove the fuses from their
holders. Inspect and test the fuses with an ohm meter for continuity. Replace
the fuses as required.
Clock Battery 204-0020 The clock battery maintains the correct date and time when AC power is not
applied to the monitor. Replace this battery approximately every 5 years.
Battery shelf life is 10 years.
Sample Pump 275-0263 The sample pump draws the gas sample into the monitor through the IR
detector and discharges the sample via the exhaust port. To replace the pump,
remove the inlet and outlet tubing, disconnect the AC power wires from the
pump and remove the pump from the monitor. Install a new sample pump.
Intake Manifold
Kit
275-1000 Up to three additional intake manifolds (4 zones each) can be installed in the
RLDS to increase the total capacity to 16 zones. Each manifold requires a
4-zone line end filter kit (275-0242) . (Follow the instructions provided to install
the manifolds. Then follow the instructions earlier in this manual to install the
air lines and complete the zone programming steps. The RLDS setup must also
be updated to recognize the new zones.)
4–20 mA DC
Interface Board
275-0030 The optional 4–20 mA DC Interface Board allows the operator to take
advantage of the current loop interfaces provided for connection of external
devices to the RLDS. The interface board plugs into the sockets provided on the
valve/pump drive PCB, and the external devices are then cabled to the RLDS
as described earlier in this manual.
