been selected, UNITS OF MEASURE will be replaced by DISPLAY UNITS. This item can be
selected anytime as ENGLISH or METRIC but applies only to dynamic readings of pressures or sen-
sor values. That is, all programmed parameters will be stored in units according to the previously
selected UNIT OF MEASURE choice. The only method to change UNITS OF MEASURE is to
reset all parameters back to the out of the box condition, erasing all currently programmed settings.
This is done through the SYSTEM TEST key.
SYSTEM TEST
The BurnerLogix contains some useful functions that are only accessible through the SYSTEM
TEST parameter.
CONTROL VARIABLE CONFIGURATION SUB-MENU
The CTRL VAR CONFIG> sub-menu allows the user to select and setup the Primary Control Vari-
able, pressure or temperature. All parameters in this sub-menu are password protected. The values of
other sub-menus, such as LAG 1 and THERMAL SHOCK, are dependent on the selections made in
this sub-menu. The STPT value is the target value the BurnerLogix will attempt to maintain. CUT
IN is a differential value that is subtracted from the STPT and determines the point where a burner
cycle begins. CUT OUT is a differential value that is added to the STPT and determines the point
where a burner cycle ends. MOD RNG is a differential value and is subtracted from the STPT and
determines the proportional band or response curve (slope) of the firing rate motor. A small value of
MOD RNG will make the burner more responsive to process load changes. Care should be taken in
selecting the proper value of MOD RNG as a system too responsive could cause overshoot and
therefore short cycling of the burner. Both INTEGRAL and DERIVATIVE terms are used to elimi-
nate steady-state error and reduce overshoot. They each have a range of 0 to 100%. This value deter-
mines how much of the error to factor in the calculation. A value of 0 turns the function off.
SYSTEM TEST
PARAMETER
DESCRIPTION
0 No action, has no function. Allows user to exit MDFY mode with no action being taken.
2 Immediately disables the enabled passwords. Both Level 1 and Level 2 passwords will need
to be re-entered to modify protected variables. Has no effect if both passwords are set to 0
(i.e. no password is enabled).
245 Reset all System Variables back to system factory default values.
