Part Name P/N Description
Water Trap 0007-1655
The water trap removes moisture that enters tubing before
allowing it to enter the internal components of the MZ 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 04-2620
The MZ monitor 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 3015-5176
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
3015-5171
Up to three additional intake manifolds (4 zones each) can be installed in the MZ
monitor to increase the total capacity to 16 zones. Each manifold requires a 4-zone
line end filter kit (3015-3411). (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 MZ setup must also be updated to
recognize the new zones.)
3015-5595 Stainless steel version of 3015-5171.
4–20 mA DC
Interface
Board
3015-5152
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 MZ
monitor. The interface board plugs into the sockets provided on the valve/pump
drive PCB, and the external devices are then cabled to the MZ monitor as
described earlier in this manual.
