Setpoint Indicator
When using the setpoint adjustment window, the
bar display switches to a setpoint display with one
or two lights illuminated. One light illuminated
indicates the setpoint, and two lights bracket the
setpoint.
Setpoint Adjustment
The setpoints are indicated in a ten-light LED bar
graph display labeled Setpoint Indicator. Two
arrow keys on the adjustment display change the
setpoints. Each single press of an arrow key moves
the indicator position a half step to the right or left.
Holding down the arrow key produces a stepping
action.
To use the arrow keys, press one of the three
adjustment buttons. For example, if the START
CLEAN button is pressed, an amber light above the
key will glow and the setpoint bar graph will
change to show the setpoint. Use the arrow keys to
change the setpoint. The lights in the setpoint
indicator bar graph display will show the new
value. When the adjustment is complete, press the
START CLEAN button again and the amber
indicator light will go out. The bar graph will
display the actual filter pressure drop. Adjust the
STOP CLEAN and SERVICE INTERVAL functions
the same way.
The system logic prevents overlap of the START
CLEAN and STOP CLEAN setpoints.
Note:
If one of the setpoint functions is left ON, the
microprocessor automatically reverts to
displaying the filter pressure drop after two
minutes.
