The following functions are available as standard:
Information about the liquid/powder level in the feed chemical container is
reported to the pump. To do so, a two-stage level switch must be fitted; it
is connected to the "Level switch" jack.
The pump can be remotely stopped via the "External control" jack.
The following functions are triggered by a key press:
The pump can be stopped by pressing the key
disconnecting it from the power supply.
Priming (short-term transport at maximum frequency) can be triggered by
simultaneous pressing of the two
The pump has several connection options for:
The relay can, in the event of fault or warming alerts or messages (e.g.
'Warning level' ), close a connected electric circuit (e.g. for an alarm horn).
The relay can be retrofitted through a knock-out opening in the pump foot -
refer to "Retrofitting relays".
This combined relay can generate a contact with each stroke via its pacing
relay in addition to its function as a fault indicating relay.
The relay can be retrofitted through a knock-out opening in the pump foot -
refer to "Retrofitting relays".
The function "Bleeding" is used for controlled bleeding of the liquid end, if
the pump is provided with the option "Automatic bleed". The "Automatic
bleed" option can be retrofitted, i.a. via a knock-out in the control unit.
There are two versions:
version with only 1 relay - to control the bleed valve.
n
Version with only 2 relays - one relay to control the bleed valve and
n
one relay free for other uses.
The I signal of the current output signals the currently calculated pump
metering volume. The option "mA output" can be retrofitted via a knock-out
in the control unit.
The option additionally always provides a fault indicating relay or a pacing
relay.
The operating and fault statuses are indicated by the three LED indicators
and the "Fault" identifier of the LCD screen, see also the "Troubleshooting"
chapter.
