Setting Up System Run On Demand (ROD)
The ROD option automatically starts or stops pumps to meet the hydraulic flow
demand from the system. The PLC monitors the hydraulic fluid flow. When the
flow changes beyond a trigger point for a set period of time, one or more of the
pumps are turned on or off.
Note Flow meters must be present on all HPU(s) within the system for ROD to
operate properly.
Refer to the previous table for a description of the controls referenced in the
following procedure.
1. On each HPU in the system, from the current screen, press the AUTO Setup
button. When the Auto Setup screen displays, make sure the Flow Meter
indicator is in the Flow Meter Present state (blue-green).
2. On each HPU in the system, check the Rated Flow Per Module.
If necessary, press the associated value pushbutton to change the flow value.
This value should only require change if the HPU is provided with pump
modules that have a different full flow rating. Refer to the HPU manual for
further information.
3. On the Supervisor HMI, from the current screen, press the Main button and
then the Setup button. When the Setup screen displays. make sure the Flow
Meter indicator is in the HPU Flow Sensors Present state (black).
4. Set the Minimum Flow.
If necessary, press the associated value pushbutton to display the numeric
keypad and change the value. Press Enter to set the value and return to the
Auto Setup screen. The range shown on the numeric keypad depends on the
number of pump modules present.
5. Set the Flow Buffer.
If necessary, press the associated value pushbutton to display the numeric
keypad and change the value. Press Enter to set the value and return to the
Auto Setup screen. The range shown on the numeric keypad depends on the
number of pump modules present.
6. Check the On Delay.
If necessary, press the associated value pushbutton to change the delay time.
Use the numeric keypad described above to increase or decrease the delay.
