1.0 Getting Started
The M501Y has been designed to operate with the M200AU low level NOx analyzer. The M200AU
manual, part number 02293, is a required reference to properly set up and operate this system.
1.1 Unpacking
1. The M200AU with NOy Option comes in three boxes.
• The M200AU analyzer
• The Bypass Pump Chassis
• The External Converter and umbilical cable assembly
2. Verify that there is no apparent shipping damage. If damage has occurred please advise shipper
first, then API.
To avoid personal injury, always use two persons to lift and
carry the Model 501 Pump Pack Chassis.
CAUTION
3. Before operation of the M200AU, remove the shipping screws as shown in the M200AU Manual.
4. Please check the voltage and frequency label on the rear panel of the instrument for compatibility
with the local power before plugging in the M501Y.
1.2 Electrical and Pneumatic Connections
1. Mount the converter on a suitable mast outside of the enclosure.
2. Route the umbilical cable assembly into the shelter.
3. Locate the M200AU and M501Y Bypass Pump Chassis in close proximity, preferably mounting
one over the other in a 19” rack.
4. Connect the electrical/pneumatic cable fittings to the rear of the Bypass Pump Chassis. Use the
tags on each tube and Figure 1.1 to match up the correct tube with the rear panel bulkhead fitting.
5. Connect the 7-pin power and signal cable to the connector on the rear of the Bypass Pump Chassis.
6. Connect the power cord to the correct line voltage.

1.3 Initial Operation
1. After confirming proper supply voltage, turn on the instrument power. If you are unfamiliar with
the M200AU with NOy Option, we recommend that you read the overview in Section 3 before
proceeding.
2. The power indicator light and display should immediately light, in addition the bypass pump
should start up. The M501Y requires about 30 minutes for the converter to come up to
temperature.
3. While the converter is coming up to temperature, the M200AU should be powered-up also. Follow
the instructions in Section 2 of the M200AU Manual to confirm proper operation of that
instrument. Note: It will take 30 minutes for the ozone generator to start up in the M200AU.
During that time the instrument will not respond to span gas.
4. After 30 min, the display on the Bypass Pump Chassis should read 315
converter is up to temperature.
5. Proceed to Section 4 of this manual to do a zero/span check.
