Start screen - Startup routine – Delay of the booster pump - Dosing delay
The startup routine:
If the device is started via the
CCT
, the startup delay runs for the booster pump
“Start
Delay b-pump”.
The startup delay is used to ensure that no air enters the booster pump
during the subsequent operation.
Setting the delay time under “Settings”
“
Start Delay b-pump”
If the specified pump pressure is reached within 5 seconds after the start of the booster
pump, the dosing delay then runs (for a fixed 3 sec) and the dosing device switches to
the set operation mode. The remaining times are displayed at the bottom in each case.
Startup mode:
If the specified pump pressure or the minimum water level is not reached/undercut within 5 seconds after
the start of the booster pump or also during operation (fault “pres. min”, “Level min”), a startup mode of
120 sec. starts again up to 5x. In this case, the boster pump runs for 5 seconds, then pauses until 120 sec.
The remaining times are displayed at the bottom in each case. If the specified values for pressure/level are
not reached, the device enters the fault mode.
Software alarms are suppressed during this time.
