7.8.2 [Operating mode] [Pulse]
With operating mode [Pulse] the pump meters a defined quantity in proportion to an
incoming pulse rate (for example, from a contact water meter).
In the operating indicator
, the symbol (
/ / / ) of the set metering rate flashes instead
of the background as normal. This indicates the control room readiness for an incoming
pulse. If the pulse occurs, the display background flashes once again on every stroke.
There are two setting options in the Pulse operating mode:
– Concentration:
