9.4.3 Contact signal control
• Use the "Start/Stop" button to start or stop the pump.
For continuous dosing in a process
For each signal received at the contact input of the pump
(e.g. from a water meter with reed contact output), the pump
doses the set dosing capacity. The dosing is continuously
distributed between the incoming contacts via a controller. The
maximum dosing capacity must not be exceeded.
Input range for the dosing capacity per contact
Even if the pump receives more contact signals than it can
process at the maximum flow rate, it only runs in continuous
operation with a maximum stroke frequency of
180/min. 120/min. in slow mode).
