COMPRESSED AIR AT ITS BEST
- Set OU1 to ImP
- Press Mode / Enter until ImPS is displayed.
- Press Set and hold.
> The current numerical value is displayed flashing for 5 s, after that,
one of the 4 digits will become active (number is blinking, can be
changed).
- Set desired impulse valence:
- First select the desired setting range (1, 2, 3 ...):
Hold
Set key until the setting range has the desired value.
- Then enter the value from the left (first digit) to the right (fourth
digit).
- Shortly press
Mode / Enter if all 4 digits have been adjusted.
If Set is pressed continuously, the display runs through all ranges.
After the end value it goes back to the start value. Then release Set
briefly and restart the setting.
8.2.7 Hysteresis function
Hysteresis
The hysteresis keeps the switching condition
of the output stable if the throughput varies
around the setpoint. If the flow rate increases,
the output switches on when the switching
point is reached SPx . If the flow rate drops
again, the output will only switch back when
the reset point rPx has been reached.
The hysteresis can be adjusted: Firstly, the
switching point is defined, then the reset
point in the desired distance.
8.2.8 Window function
Acceptance range
The window function allows the monitoring of
a defined acceptance range. If the flow rate
moves between switching point
SPx
and reset
point rPx , the output is switched through
(window function / normally open) or opened
(window function / normally closed).
The width of the window is adjustable
through the distance from SPx to rPx.
SPx = upper value; rPx = lower value.
