NONE
Select NONE if you do not wish to assign a relay to an output
channel.
Analyte 1–8
Defines the analyte (species) of interest for the relay output.
You can assign a different relay for each channel. To assign a relay
to a channel, select an analyte and press
ENTER
. Note that the
actual species name (e.g., SO
2
) will be displayed on the screen, not
“Analyte.”
Relay 1–8 Value
Defines the Low or High Alarm Limit threshold for each relay (user
input required). This parameter only applies if Relay Function is set to
Low Limit or High Limit .
Relay 1–8 Delay
Defines the delay time to de-energize the relay after the analyte con-
centration goes outside the limit set with Relay Value .
For example, if Relay Delay is set to 5 seconds, the analyte concentra-
tion can exceed the High Limit for up to 5 seconds at a time without
de-energizing the relay. If the concentration stays high for more than
5 seconds, the relay will be de-energized. The range is 0–3600 seconds.
This parameter only applies if Relay Function is set to Low Limit or
High Limit .
To change the settings for a relay:
1. Enter a password to allow changes to be made to the relay settings.
2. Select one of the Relay ( 1–8 ) sub-menus. Press
ENTER
to view the pa-
rameters for that relay.
3. Select the required parameter ( Relay Function, Source, Value, or Delay ),
change the settings, and press
ENTER
.
Repeat this step for each parameter and each relay.
When entering a value for the Relay Value and Delay parameters:
• Use the
UP
/
DOWN
arrow key to increase/decrease the value in
increments of one (1.00). This works best for minor changes. The
relay value is displayed on the right side of the screen.
• If a value exists, use the
LEFT
arrow key as a backspace to erase the
characters to the left of the cursor ( ‘ _ ’ ) if applicable, then use the
numeric keys to enter the new value. This works best for drastic
changes.
