DISPLAY LAYOUTS
CUSTOM 1 AND 2 Display
This screen is the same setup for both Custom Screen 1 and 2. First the operator can scroll through which field they
want to change with the dial and then select it by pressing in the dial. Second the operator will select a value for each
decimal place and press the dial to enter that number. The number entry selection starts from the left side of the
screen and moves to the right. The following parameters include:
Motor Displacement in cubic inches (0.00 decimal places)
*Efficiency of the system (0.00% decimal places)
Gearbox ratio (0.00 decimal places)
* Efficiency refers to the Drives total mechanical efficiency regarding the hydraulic motor and the gearbox. To determine
how efficient a Drive is the hydraulic motor and gearbox efficiencies need to be added together to determine the total
amount of efficiencies to be subtracted from 100%.
Example: 15% - Motor (Motor is 85% efficient)
+3% - Gearbox (Gearbox is 97% efficient)
18% - Total (Efficiency to be subtracted)
100% - Starting efficiency
- 18% - Total (Efficiency to be subtracted)
82% - Total Drive Efficiency.
82% is the overall Drive efficiency and will be entered in the System Efficiency box.

NOTE:
The Two Speed button (located on the bottom right next to the ESC button) toggles between On and
Off depending on if the Drive is a two speed model. If the option is set to “Off” then the Stage 2 numbers will
not be used in the calculations. If it is set to “On” then the Stage 2 numbers will be used in the calculations.
The two speed option is only to be used with Pengo RT series Anchor Drives. The
custom two speed option will not recognise other manufactures Drives.
See Efficiency example
below.
In order to enter values
in the Stage 2 boxes
this button must be set
to “ON”.
Enter displacement in
cubic inches.
Note: The gearbox and motor efficiencies
can normally be obtained from the Drive
manufacturer.
