As the feed pump can be switched on and off externally, there is an addi‐
tional input at the Ultromat control for determining the state of the motor
starter (potential-free auxiliary contact). The evaluation of the min. contact
at the flow meter is only carried out if the feed pump is running and conse‐
quently the potential-free auxiliary contact at the motor starter has been
closed.
If the feed pump is stationary, the potential-free contact is not closed and
the min. contact at the flow meter is not evaluated.
5.2.11 Empty signal for concentrate tank
The
‘Empty signal concentrate tank’
option comprises a float switch,
which is inserted from above in the delivery drum.
5.2.12 Dosing monitor for liquid concentrate
The Ultromat
®
can be operated with liquid polymer. The concentrate pump
doses the concentrate into chamber 1. The dosing monitor can only be
used when an eccentric screw pump is being used. The dosing monitor
comprises a flow adapter and a flow sensor.
5.2.13 Top hopper 50 l, 75 l and 100 l
Should an enlarged powder reservoir be required, top hoppers with an
additional volumetric capacity of 50, 75 and 100 litres are available.
5.2.14 Powder feeder device for automatic refilling
A powder conveyor unit can be used for the automatic filling of the powder
hopper with powdered polymer. A powder feeder device can be mounted
directly onto the dry feeder or top hopper by means of an adapter plate.
The installation of a 50 l top hopper with an adapter connection is recom‐
mended to overcome short periods of service work on the powder con‐
veyor or when there is a high consumption of powder.
