Dynalco Catalyst Monitor - Manual (Page 16)

Alarm Outputs
The Catalyst Monitor will alarm when channel values or differential values are above or below
limits as specified. Alarms can be configured as either latching or non-latching. If an alarm
condition is met, the red LED on the front panel will blink and the digital output(s) will trip. The
alarm point name (ch1, ch2, df1, df2) that caused the alarm will be stored in memory with
date/time stamp info. Non-latching alarms will reset the alarm if its value returns to normal.
Latching alarms require manual resetting via the front keypad.
WARNING:
The alarm / shutdown output should be tested monthly for proper operation, especially
if being used for over temperature shutdown or other critical function.
Catalyst Inlet Temperature Monitoring (per RICE NESHAP requirements)
The Catalyst Monitor will allow you to configure any one channel to monitor the catalyst inlet
temperature based on a 4 hour rolling average per the RICE NESHAP mandate. To set this
up, first go to the main menu, then select “System.” Select “EPA enable” and then select
which channel is monitoring the catalyst inlet temperature. Please note that once this is
configured, the channel representing the catalyst inlet temperature will always display the 4
hour average, not instantaneous exhaust temperature.
IMPORTANT NOTICE REGARDING POWER INTERRUPTION:
If input power to the Catalyst Monitor is disconnected during a data log operation, there is the
possibility of losing data (see page 2).
To prevent this, it is important to turn off the data logging prior to power disconnect. This is
accomplished through the “Data Logging” icon on the main menu. When this is selected, the
first screen will allow you to select “Stop Logging.” Pressing the
arrow will provide
instructions for a safe power down.
The data logging will be enabled automatically when power is re-applied.
