9.Alarm 4 setup:

Alarm 4 is a dedicated fault alarm. When a fault condition exists, the red LED on the front display will light.

a.From the menu header screen (step 6) move the cursor to "Alarm 4 setup."

b.To disable the alarm, press Edit (F4) and use the key to change the "Fault" to "Off"

10.Feed limit timer setup:

Alarm 1, 2, or 3 can be configured as a feed limit timer. The feed limit timer prevents overfeeding of treatment chemicals by automatically turning off the relay after a timeout period.

a.From the menu header screen (step 6) move the cursor to "Feed limit timer." Press Enter (F4).

b.With the cursor on "Feed limit" press Edit. Use the key to scroll through the choices: disable, AL 1, AL 2, and AL 3. Press Save (F4) to store the selection.

c.Move the cursor to "Timeout". Press Edit (F4) and use the arrow keys to change the timeout to the desired value. Press Save (F4) to store the setting.

Operation of the feed limit timer. When a feed limit alarm has timed out, "Feed limit alarm 1" (if alarm 1 was chosen) appears in the display. At the same time the red FAIL LED will light and alarm 4 will close (if not turned off), and the selected feed limit relay (alarm

1)will open (de-energize). All other alarms and current outputs will remain unchanged. The relays remain in the state described until the Ack (F2) key is pressed, at which time the analyzer returns to normal operation and the feed limit clock starts again.

NOTE

Pressing Ack (F2) acknowledges all conditions that turn on the red LED. If another event occurs after F2 is pressed, F2 must be pressed again to acknowledge the new event.
