6.7.2 Additional display

The additional display provides additional 
information about the current pump status. The value 
is shown in the display with the corresponding 
symbol.
In "

Pulse

" mode the "Target flow" information can be 

displayed with Q = 1.28 l/h (see fig. 

19

).

6.8.1 Relay outputs

Applies to DDC-AR control variant

The pump can switch two external signals using 
installed relays. The relays are switched by 
potential-free pulses. The connection diagram of the 
relays is shown in section 

4.3 Electrical connection

Both relays can be allocated with the following 
signals:

* Factory setting

** The correct transmission of incoming pulses can 

only be guaranteed up to a pulse frequency of 
5 Hz.

6.8.2 

External stop

The pump can be stopped via an external 
contact, e.g. from a control room. When activating 
the external stop signal, the pump switches from the 
operating state "Running" into the operating state 
"Standby". The corresponding symbol appears in the 
"Signal/error display" area of the display.

The contact type is factory-set to closing contact 
(

NO

). In the "

 > 

Inputs/Outputs

 >

menu, the setting can be changed to opening contact

Caution

Frequent disengagement from the mains 
voltage, e.g. via a relay, can result in 
damage to the pump electronics and in the 
breakdown of the pump. The dosing 
accuracy is also reduced as a result of 
internal start procedures.
Do not control the pump via the mains 
voltage for dosing purposes!
Only use the "

External stop

" function to 

start and stop the pump!
