5. Operator Control Unit (OCU)
The OCU is a lightweight, palm-sized, extremely rugged customizable controller for use with any CattronControl
series MCU.
Each OCU is designed to meet a specific control application. Two standard OCU options are available: one with a
toggle select switch on the end cap and one without this switch.
Each pushbutton may have its specific control function identified from a sheet of self-adhesive labels that is
provided for this purpose.
Referring to Figure 1, advanced operational security and configurability are made possible by the use of a
removable RFID 'TransKey' which, when installed in the OCU, defines and enables the appropriate operating
parameters such as frequency and address. A label with the ID address is affixed to each TransKey.

Note: The OCU and MCU TransKeys must not be swapped. The OCU TransKey is black. The MCU
TransKey is yellow. Swapping TransKeys will result in OCU/MCU fault indications and the system will
not go into operation.
Referring to Figure 2, the keypad unit and electronics are contained in an IP65-rated aluminum housing which has
tough, protective rubber end-caps for switch protection and high impact resistance.
The TransKey is placed into a slot within the confines of the r
ubber ‘bumper’ that surrounds the top end-cap.
Separate ON/OFF and STOP switches are located next to the TransKey.
A sealed elastomer keypad on the OCU front face contains large pushbuttons (function keys), which are coated
with clear epoxy for additional durability. Each pushbutton is labeled for a specific function. Pushbuttons are two-
step (i.e., dual pressure) operation.
Both steps of each individual pushbutton can operate different functions. Typically the first step controls a
direction or function and the second step controls a speed increment. However, it is possible with a step-less
drive to use the second step as accelerate, the first step as hold speed and the released state as decelerate.
Any function is active only as long as the respective pushbutton is pressed. When the pushbutton is released, the
function stops automatically.
The ‘STATUS’ LED (located in the center of the row of LED lights) indicates the operational mode and any error
messages.
