"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
[STOP/START]
.
Priming can be triggered by pressing
[]
Priming.
5.7 Options
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" - "Relays” chap‐
ters.
"Fault indicating relay and semiconductor relay" option: In the event of
fault signals, 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" - "Relays” chapters. 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 "0/4-20 mA analogue current output and fault indicating relay" option
can be retrofitted via a knock-out in the control unit.
The option also always includes a semiconductor relay - see above. Other
functions can be adjusted – see "Settings" - "Relays” chapters.
5.8 Function and fault indicator
The operating and fault statuses are indicated by the three or four LED
displays and the
‘Error’
identifier on the LCD screen:
