If the unit is off on a shutdown alarm, or running but in a limit alarm condition, the cause, date/time,
and UNIT STATUS will appear in the ALARM ACTIVE screen. The remote alarm relay will close,
and a red light will appear behind the LEFT button. The light will go out when the fault is cleared.
If there is a simultaneous occurrence of more than one alarm, the others will appear in additional
screens below this one, accessed by the DOWN ARROW.
If an alarm occurs, press the MENU button, then the LEFT button for ALARM, and then the left
button again to reach the ALARM ACTIVE screen.
The cause of the alarm must be remedied before attempting to clear the alarm. To clear the alarm(s),
scroll down to the last screen (bottom screen above) and press ENTER. The SET UNIT SPs screen
will appear and the password will be asked for. Press ENTER and the cursor will flash in the
password field. Press the UP button to scroll the numbers up to the required password. Then press
ENTER to enter the password. Then return to the ALARM ACTIVE screen and press ENTER to
clear the alarm.
If other faults have appeared, they will all be cleared at the same time.
SET MENUS
Changing setpoints; setpoints are changed as follows:
1. A password must be entered before attempting to change any setpoint. Two four-digit passwords
provide OPERATOR and MANAGER levels of access to setpoints. The passwords are
preprogrammed into the controller. The Operator Password is 0100, the Manager Password is
2001. Either password must be entered using the ENTER PASSWORD screen (15) before a
protected setting can be changed. The quickest way to reach screen (15) is to press the MENU
key, then press SET (UP Arrow Key), then press the UP Arrow key, which will go to screen (15).
Press ENTER to reach the numerical field, hold the UP Arrow key to scroll the numbers up to
the desired password, then press ENTER. The word “Operator” or “Manager” will appear next
to Level when the password is entered properly. Setpoints can now be changed. Once entered, a
password remains valid for 15 minutes after the last key-press.
2. Select the desired menu by scrolling through SET menus with the UP, DOWN, LEFT and
RIGHT ARROWS. Alternatively, press the MENU button, select the type of setpoint desired,
then scroll up or down to the desired menu screen.
3. When the desired menu screen is reached, select the desired field within the menu by moving
between lines using the ENTER key. Some fields may not be accessible due to settings in other
menus.
4. If a numerical value is being changed, use the INCREMENT key (UP ARROW) to increase or
the DECREMENT key (DOWN ARROW) to decrease the value of the setpoint.
5. If a word type setpoint (for example, YES or NO) is to be selected, the choices are pre-loaded
into the menu and selected by scrolling through the available setpoint options using the UP
ARROW key.
