Data Logging”
The setup for EPA required logging of the catalyst inlet temperature based on a 4-hour rolling
average is described in the section named “System” on page 14.
Additional data logging may be configured when you select the “Data Logging” icon. The
Catalyst Monitor can be configured to log any of the parameters being monitored, at user
defined time intervals. The values are saved to an internal flash memory with sufficient
memory to hold up to 500,000 data values with date / time stamps. These values can be
downloaded at any time to a PC using Dynalco’s “Log Reader” software.
The logging of any parameter is configured as an event. The Catalyst Monitor will allow up to
(10) individual events to be defined.
It’s also possible to configure an event that will log the catalyst differential pressure at defined
intervals. Note that some users may decide to manually record differential pressure once per
month since this value needs to be recorded with engine fully loaded per RICE NESHAP.
Example:
To configure data logging of catalyst differential pressure after engine warm up:
(Note that this configuration will require an input signal from a magnetic pickup to sense
engine running.)
Using the arrows on the keypad, select the “Data Logging” icon.
Next, select “Setup Log Events” and press the
arrow.
The next screen will display a list of (10) events that can be configured. If this is the first event
to be programmed, select “Event 1” and press the
arrow.
Next select “Enable” and press the
arrow.
The next screen allows you to define an “On” condition. The configuration for logging the
differential pressure will require an “On” condition defined by an “engine run” signal. See
above (page 9) for the procedure for configuring the “run” signal. In this case, select “Yes”
and press the
arrow.
Select “Edit Compare” on the next screen and press the
arrow.
Select “Compare 1” on the next screen and press the
arrow.
Select “RPM” on the next screen and press the
arrow.
Select “Greater Than” on the next screen and press the arrow.
