The procedure for modifying a setpoint is as follows:
1.
Enter adjust ratio mode. “A n” is displayed in addition to the servo-motor positions, where n is
the number of the setpoint which is closest to the current firing position.
2.
Use the
LEFT/RIGHT
scroll keys to point to the profile point number “A n” to be adjusted and
use the
UP/DOWN
keys to move to the setpoint in the firing range to be altered.
3.
Wait for the “A n” display to stop flashing and modify the fuel and air servo-motors as required.
4.
If the modified positions are not required, press the
AUTO MAN (NEXT)
key to return the
motors to their original positions or use the scroll keys to select a different setpoint.
5.
Press the
COM (ENTER)
key to store the new motor positions for the current setpoint.
6.
Repeat steps 2-5 as required. Each time step 5 is completed, the new positions will be stored
permanently.
7.
Leave adjust ratio mode
If the “A n” display is flashing, it will not be possible to adjust the position of any of the motors. This
may be for one of the following reasons:
• The burner is not firing. Switch the burner on and wait for the unit to begin modulating.
• The current setpoint is A0, A1 or A2. Use commission ratio mode to adjust these setpoints.
• The servo-motors are moving to the required positions. Wait for the servo-motors to stop moving.
Leaving adjust ratio mode:
To leave adjust ratio mode and return to run mode, press the key labelled
DATA (RUN)
followed by
the
COM (ENTER)
key.
Finding the Software Engineering Code
There are two methods for finding the software Engineering Code:
1.
From run mode, press the
COM
key. The software engineering code is shown on the display.
2.
Use the engineer’s key. Refer to Engineer’s Key section for details.
