SETUP EXPLANATION
The SETUP program allows the user to make adjustments to the time and date, maximum
and minimum air temperatures and other variables that may need to be adjusted to match
the heater to the system. These adjustments can be made while the heater is on or off.
TO ENTER SETUP PROGRAM -- The SETUP program is run from the Diagnostic
Module Display (DMD) at the local panel. To enter SETUP, turn the +/- selector switch
until the blinking cursor is on SETUP. Press the SELECT button to enter SETUP. Use
the +/- selector switch to maneuver through the various setup selections. Press the
SELECT button to choose the variable you want to change. Follow the prompts on the
screen and use the +/- selector switch to adjust the variable.
Following are the SETUP selections.
BACK -- Exits the SETUP program.
24 HR SHUTDOWN -- This step is used to enable or disable the automatic 24-hour
shutdown. If this feature is enabled, everyday at a user defined time the Heater will
automatically shutdown and ERROR 131 will be displayed. To prevent the automatic
shutdown, this feature should be disabled.
To enable this feature, turn the +/- selector switch to “+” for YES. To disable this
feature, turn the switch to “-”. Once the desired option is selected, press the SELECT
button to continue. If the “disable” option has been chosen, the test program will
advance back to the 24 HR SHUTDOWN prompt. If the “enable” option is chosen, a
prompt will appear which allows you to set the time you want the Heater to automatically
shutdown. Once the shutdown time has been set, press SELECT.
CHANGE TIME/DATE -- Time and date are confirmed or changed in this step. Time
and date are used in the logging of errors and alarms within the PLC. If the time and date
are correct, press SELECT to proceed. If an adjustment is needed, turn the +/- selector
switch to the left (-) momentarily. The confirmation will change to “NO” and the
SELECT button will advance through all time and date variables. At each position, use
the +/- selector to change the value appropriately to obtain the correct time and date.
When finished, confirm the new time and date by pressing SELECT to proceed.
BATTERY STATUS -- The PLC’s battery status will be displayed. If battery power is
lost, retention of the heater’s error history will be lost along with custom settings and
variables. The operating program is stored in nonvolatile memory so fundamental
operation of the burner will never be jeopardized by the loss of battery power. The
battery may be replaced at any time, even during the heater’s operation, without
adversely affecting the system. Press SELECT to proceed.
