"Level switch" function: Information about the liquid/powder level in the
chemical feed container is reported to the pump control. To do so, a two-
stage level switch must be fitted; it is connected to the "Level switch" ter‐
minal.
"Pause" function: The pump can be remotely stopped via the "External
Control" terminal. The "Pause" function only works via the "External Con‐
trol" terminal.
The following functions are triggered by a key press:
"Stop" function: The pump can be stopped without disconnecting it from
the mains/power supply by pressing the
"Priming" function: Priming (short-term transport at maximum frequency)
can be triggered by simultaneous pressing of the two arrow keys.
The pump has several connection possibilities for the following options:
"Output relay" option: In the event of fault signals, warning signals, stop‐
ping of the pump or tripped level switches, the relay connects to complete
an electric circuit (for alarm horns etc.).
The relay can be retrofitted via a knock-out in the drive unit.
The various functions can be adjusted, see "Settings" - "Relay".
"Fault indicating and semiconductor relay" option In the event of fault sig‐
nals, warning signals, stopping of the pump or tripped level switches, the
fault indicating relay connects to complete an electric circuit (for control
panel etc.).
In addition to the fault indicating relay, the pacing relay can be used to
make a contact every stroke.
Other functions can be adjusted, see "Settings" - "Relay". The option can
be retrofitted via a knock-out in the drive unit.
The current output I signal indicates the pump's actual calculated metering
volume.
The option "0/4-20 mA analog current output and fault indicating relay" can
be retrofitted via a knock-out in the control unit.
Additionally the option always provides a semiconductor relay, see above.
Other functions can be adjusted, see "Settings" - "Relay".
The operating and fault statuses are indicated by the three LED indicators
„Error" identifier on the LCD screen, see also the "Trouble‐
and the
shooting" chapter.
