Flushing Mode - Moog RKP-D User Manual

7 Pump functions
7.2.10.1 Objects 0x2107 - 0x2109: Local holding pressure switchover
<HoldPressureTrigger>
This parameter sets the holding pressure trigger level at which the internal holding pressure setpoints (param-
eters <PressureSetpoint> and <SpoolPositionSepoint> are activated by the RKP-D when the local holding
pressure switchover is activated (see Figure 42).

0x2107 1
<PressureSetpoint>
The pressure setpoint is activated by the RKP-D when the holding pressure trigger level
(<HoldPressureTrigger>, 0x2107) is reached (see Figure 42). This pressure is held until a new pressure set-
point is transmitted or the trigger is disabled.

0x2108 1
<SpoolPositionSetpoint>
The position setpoint is activated by the RKP-D when the holding pressure trigger level
(<HoldPressureTrigger>, 0x2107) is reached (see figure 42). This position is held until a new pressure set-
point is transmitted or the trigger is disabled.

7.2.11 Flushing mode

This function is included in digital pumps with internal pressure supply. The flushing mode prevents overheat-
ing of the pump. If all relevant demand values (p, Q, or both) are below 1 %, the pump might overheat be-
cause there is not enough flow to cool the pump. Therefore the pump goes into flushing mode after the time
stored in the parameter 0x21A1 (<FlushingTime>) has elapsed.
The flushing time represented by the parameter 0x21A1 is stored in seconds. Typically the value is 180.
Hence, if the relevant demand values are below 1 % for the duration of 3 minutes, the pump will go into flush-
ing mode.
