4.8.2.9 Test 1.9 Water Inlet, Upline Tank and Flow Pump FPE
1. Activate the Water Inlet menu with the Water
Inlet key in the LL Manual Test menu. The
following menu is displayed.
2. Check the functions with the appropriate keys.
Valve VVBE You can set the flow of the upline tank control valve VVBE. VVBE must
guarantee a flow of ≥ 1200 ml/min at a water inlet pressure of approx. 0.9 bar.
Level Sensor NSVB The level of the upline tank VB is displayed on the screen by the level sensors
(NSVB_O high sensor and NSVB_U low sensor).
Flow Pump FPE If the upline tank is full the valve VVBE is closed automatically. If the flow
pump FPE is activated FPA is also switched on, to allow an unrestricted flow
through the balance chambers.
Emptying The degassing pump PE is permanently switched on to allow a circulation in
both compartments of the upline tank.
VEB is opened. If the emptying is activated to drain the machine the pumps are
switched on for a short period and VVBE closed.
All balance chamber valves are opened and the outlet flow pump FPA works in
main flow with the same speed as the inlet flow pump FPE. The degassing
pump EP runs and the degassing bypass valve VEB is open.
