The
‘Config I/Os’
menu is used to assign functions to the "Config
I/O” (-
Ä ‘Control elements, overview’ on page 18
) socket pins.
You can configure the pins as an input – for the timer.
The pins can be configured as outputs (timer, warning, error, auxil‐
iary,...).
It is also possible to use
‘Selective errors’
or
‘Selective warning’
to
issue very specific errors or warnings (Diaphragm rupture, Defec‐
tive stroke met., Air in dosing head, ...).
11.2.10 Bleeding
‘Menu / Information

The
‘Bleeding’
function is used for controlled bleeding of the liquid
end.
The software solution is always in the pump control. The pump
calls up the
‘Priming’
function for bleeding. The pump can there‐
fore pump the gas bubbles out of the liquid end even without a
bleed valve (solenoid valve) – depending on the back pressure.
If the pump has "Automatic bleed" via the "relay identity code
option (retrofittable), the pump can be bled via a bleed relay.
There are 2 hardware options for automatically bleeding the dis‐
charge side:
n via ProMinent's bleed module in the liquid end.
n via a customer implemented bleed facility in the discharge line.
The relay - "Relay” – "with automatic bleed" -
changes its switching status for the period during
which the pump is priming.
The
‘Bleed’
function can be triggered in 4 ways:
1 - Not (
‘Off’
).
2 -
‘Periodically’
by an internal signal - defined by
‘Cycle’
and
‘Duration’
.
3 - By the
‘Air lock’
internal signal
4 - If one of the two signals occurs (
‘Both’
).
