5.13 Timer The pump is dosing the set quantity in batches at the maximum capacity or the set maximum capacity, see section 5.16. The time until the first dosing "NX" and the following sequences "IN" can be set in minutes, hours and days. -
Page 22: Batch
5.14 Batch The pump is dosing the set quantity in batches at the maximum capacity or the set maximum capacity, see section 5.16. The quantity is dosed every time the pump receives an external pulse. If the pump receives new pulses before the previous Set value per batch batch is performed, these pulses will be ignored. -
Page 23: Capacity Limitation
5.16 Capacity limitation This function offers the possibility of reducing the maximum pump capacity (MAX. CAP.). It influences the functions in which the pump is normally operating at maximum capacity. Under normal operating conditions, the pump cannot operate at a capacity which is higher than the one stated in the display. -
