4 Adjusting Cut IN and Cut OUT
Follow steps 1 through 3 above.
4. If the display shows the angular positions of the servomotors, press the MODE key to change to
option parameters. Using the up or down key, move to OPTION 21.6 (22.6) for Cut In or 21.7
(22.7) for Cut Out. This is the control value the Nexus will start/stop the burner after reaching the
cut in/out value. This value is a differential value when option parameter 21.5 (22.5) is set at 2.
That is, it is subtracted/added from/to the operating set point. Once set, this value will follow any
change in the set point programmed in option 21.1 (22.1). These values are actual values if 21.5
(22.5) are set to 1. (see table below)
Option parameter
21.5 (22.5) value
Meaning
0 No limits. The burner will run until another method is used to switch
it off.
1 Absolute limit. The values entered in option parameters 21.6
(22.6) and 21.7 (22.7) are the actual limit values.
2
Deviation limit. The values entered in option parameters 21.6
(22.6) and 21.7 (22.7) represent a deviation (i.e. offset) from the
setpoint 1 control value. This means that if the setpoint control
value is changed, the limits are automatically changed
correspondingly.
5. Use the left or right arrow key to move the cursor to the lower portion of the display then - using
the up/down arrow key, change the setting.
6. Press the ENTER key to accept the new set point.
7. To exit and return to the normal run mode press the RUN key followed by the ENTER key. See
two examples below:
