7.1.5 Two-row pump unit programming variants
Time ON / Lower row time OFF / Upper row time OFF variant
(For flow diagramm see sub-section 11.3.5)
(Precondition: Control unit C/C3)
In this setting, the pump unit will be switched on within a particular adjustable cycle time for a
particular duration (delivery time). Here, the cycle time means the time that elapses between
the beginning of a delivery interval and the beginning of the next one.
For both the lower and upper row of elements, different cycle and delivery times can be set.
In case of an overlapping delivery between the lower and upper element rows, the running
delivery will be stopped first. Then, switch-over to the other row will be made.
Time ON / Lower row time OFF / Upper row distributor pulses OFF variant
(For flow diagram see sub-section 11.3.6)
(Precondition: Monitored progressive distributor in the upper row of elements,
control C3)
In this setting, the lower element row of the pump unit is switched on within a particular
adjustable cycle time for a particular duration (delivery time), whilst the upper element row is
switched on within a particular adjustable cycle time for a particular number of pulses from
the monitored progressive distributor. Here, the cycle time means the time that elapses
between the beginning of a delivery interval and the beginning of the next one.
For both the lower and upper row of elements, different cycle and delivery times as well as
progressive distributor pulses can be set. In case of an overlapping delivery between the
lower and upper element rows, the running delivery will be stopped first. Then, switch-over to
the other row will be made.
The distributor monitoring P17 will be switched on in this mode automatically (when P15 is
reset to 1).
P17 will not be reset automatically.
When changing the mode or resetting P15 to 0, the status of P17 needs
to checked and reset manually, if necessary.
Time ON / Lower row distributor pulses OFF / Upper row time OFF variant
(For flow diagram see sub-section 11.3.7)
(Precondition: Monitored progressive distributor in the lower row of elements,
control C3)
In this setting, the lower element row of the pump unit is switched on within a particular
adjustable cycle time for a particular number of pulses from the monitored progressive
distributor, whilst the upper element row is switched on within a particular adjustable cycle
time for a particular duration (delivery time). Here, the cycle time means the time that elapses
between the beginning of a delivery interval and the beginning of the next one.
