1.
The pump control stops the normal metering operation - the
"Stop Pause" symbol appears on the LCD screen.
2. Only with bleed relay: After 1 s, the pump control opens the bleed
valve on the liquid end (via the bleed relay and the solenoid valve).
3. 1 s later, the pump starts to run at its maximum possible stroke rate
(as during priming) - the "Air lock" symbol appears on the LCD
screen instead of the "Stop Pause" symbol.
4. The pump operates in this way for the total set time.
5. Once the set time has elapsed, the pump stops – the "Stop Pause"
symbol appears on the LCD screen again.
6. Only with bleed relay: After 1 s the pump control closes the liquid
end bleed valve.
7.
After 1 s the
"Stop Pause" symbol disappears and the pump
recommences normal operation.
If the pump was in the "Stop" state at the time of triggering (
[STOP/START]
, Pause, Error), the start of the bleed procedure is delayed
- until this state has been cleared.
If the pump switched to "Stop" state during the bleed procedure, the pump
control jumps immediately to phases 5 and 6 - see above. This definitely
cancels the bleed procedure. As soon as the "Stop" state is cleared, the
bleed procedure starts from the beginning.
