IV Venting program
By pressing the button for longer, a venting program will be started. This program runs the
pump alternately at different speeds. This leads to the following display: The first segment is
a moving icon to indicate that the program running. In segment 2 and 3 is displayed in which of
16 stages the program is currently. Begun is counted down at level 16 and
then. Every level takes about 1 minute. After the end of the entire program
will be automatically returned to the display of normal operation. The ven-
ting program can be terminated prematurely by pressing the button for
a long time.
V PWM / 0-10V operation
In order to use the special function PWM / 0-10V operation, the pump must be equipped with
an additional module be retrofitted. If this function is to be used, it is first in the characteristic
curves To change selection menu. This is done by briefly pressing the button.
After that press the same key again, this time for more than 3 seconds.
The display changes to the following display. By pressing the + or - button
can now select one of 4 PWM / 0-10V operating modes are selected. Dis-
play P-1 to P-4. After 8 seconds, the pumps change to PWM / 0-10V mode.
The display now shows the power (W) alternating with the PWM / 0-10V mode name (P-1 to P-
4) displayed. The pump must now be controlled with an external PWM / 0-10V signal. The dis-
play alternates between power (W) and PWM / 0-10V mode name (P-1 to P-4). To cancel PWM /
0-10V operation, press the key for less than 3 sec. To enter the menu for Selecting the PWM
/ 0-10V modes to arrive. Will this button be longer than 3 seconds pressed, the pump changes
to the characteristic menu and from there automatically after 8 seconds into normal operation.
P 1:
• between 0 and 20% PWM / 0 and 2V 0-10V Signal rotates the pump at minimum speed.
• from 20 -100% PWM / 2-10V 0-10V Signal the speed increases up to the maximum value.
P 2:
• between 0 and 20% PWM / 0 and 2V 0-10V Signal turns the pump at minimum speed.
• from 20 -100% PWM / 2-10V 0-10V Signal, the speed decreases from the maximum value
to its minimum value.
P 3:
• between 0 and 20% PWM / 0 and 2V 0-10V Signal the pump is switched off.
• From 20 -100% PWM / 2-10V 0-10V Signal, the speed increases from the minimum value
to the maximum value.
P 4:
• between 0 and 20% PWM / 0 and 2V 0-10V Signal the pump is switched off.
• from 20 -100% PWM / 2-10V 0-10V Signal, the speed decreases from the maximum value
to its minimum value.
Without a PWM / 0-10V signal connected, the pump turns into P 1 and P 2 at minimum speed.
In P 3 and P 4 it is turned off. The settling time for speed changes is about 2 seconds.
