1 Introduction
This quick reference guide provides a minimum set of information to enable a system to be started, the user
should always refer to the full user manual for full details and additional safety related information.
Full user manuals for Industrial products can be located on cattron.com as follows.
Using the top navigation of the website, select the ‘Product’ menu and select the product brand of your system.
Then scroll down and select the name of your product. From there select the ‘Resources’ tab near the bottom of
the page to locate the user manual and many other useful items related to your product.
2 MCU Connections
The MCU terminal connections are plug in screw type connectors, the location and pin numbering of each relative
to the OCU buttons are identified in the system configuration drawing provided with your system.

2.1.1 Mount and make connections to the MCU
 Mount the MCU using the mounting feet provided.
 Conforming to local and national electrical codes, make the appropriate connections as per the
configuration drawing provided with your system.
 In almost all cases the implementation of an appropriate main line contactor (MLC) power circuit is
required using K18 and K19 to maintain the MLC and possibly K16 to reset the MLC.
 Determine the correct power option of your MCU and connect power and ground (either 110-240VAC or
24VDC) to J1 via a local disconnect switch.
 Check the wiring and turn on the MCU power, the MCU status LEDs will be seen to run through
diagnostics and settle with two green and one amber, indicating the MCU is ready.

3 Operating Instructions
3.1 OCU First Use
By removing the two screws for the battery cover, insert the AA batteries provided.
Referring to the figure below, battery access is under the cover on the rear of the OCU by the belt clip.

3.2 OCU to MCU Association
The Cattron-S series OCUs need to be paired with the MCU before first use, this is a simple procedure where the
MCU and OCU learns the others identity.
This process is called Association and can be carried out either directly or using CattronLink™
 An OCU can only be used with the last MCU to which it was associated.
 An MCU can only store the identities of eight OCUs, e.g. operating unit 1, spare 1, spare 2 etc. after eight
OCUs have been associated the OCU dis-association process must be followed before any new OCUs
can be associated.
A. To initiate the association process the MCU should be in Passive mode (not operating with any other OCUs.)
B. The OCU to be associated should be woken from sleep and in passive mode so the green status LED is
illuminated.
C. Preferably and if the MCU is accessible press and hold pushbutton 1 in the MCU at the same time as
initiating step D. If the MCU is not accessible make sure the OCU is as close to the MCU as possible and
certainly closer to the intended MCU than any other MCU. (The logical association process is; MCU with
the button being pressed and/or the MCU with the strongest RF signal).
D. Press and hold the On / Alarm button on the OCU for more than 10 seconds, the Status LED will turn Blue,
release the OCU ON/Alarm (and MCU button if pressed).
E. At successful completion of Association, the OCU status LED will revert to Green, if the association fails it
will change to Red and association should be re-tried.
Now press and hold the Stop button to turn off the OCU, turn it back on again and complete the Start sequence
so the Stop switch is flashing, then using the On/Alarm button verify that the correct MCU is being controlled.

3.3 Dis-Associating all OCUs from an MCU
It is possible to dis-associate all OCUs from an MCU by the following method.
With the MCU in Passive mode (not connected to an OCU), press and hold button 1 for 20 seconds until the RED
LED illuminates, then release button 1.
3.4 Operating the OCU
Ensure that the OCU being used is the correct one for MCU and the machine to be controlled
3.4.1 Transition OCU from OFF to Passive Mode
Press the START button, this will wake the OCU from sleep to a fully tested PASSIVE non-transmitting mode.
You will see all LEDs flash briefly to confirm they are all working.
The center Status and Right-hand LEDs 1 & 2 will then illuminate, the battery status will be shown for a few
seconds on LEDs 1 & 2, see chart below.

3.4.2 Transition OCU from Passive Mode to Active Mode
From Passive Mode the OCU can be moved into an Active (Transmitting) mode;
OCU start sequence; From Passive Mode, Press the Stop switch and then press the Start switch within 3
seconds.
The Status E-Stop LED will now flash showing it is transmitting, the Status LED will remain OFF unless the
battery is between 20 and 40% when it will flash Amber or below 20% when it will be flashing Red.
At this point the OCU is operative and the target machine will be under direct control, verify the connection by
activating a non-motion function such as the Alarm button. Test all functions briefly at the start of the work
session.
3.4.3 Transition OCU from Active Mode back to Passive Mode
The machine may be brought to a halt at any time by simply releasing the motion control button that will
deactivate the motion control, or in an emergency pressing the STOP button that will typically deactivate the
crane main contactor as well. When the STOP button is pressed the OCU sets the STATUS LED Red and the
ESTOP LED Green and sends a positive stop command to the MCU and then terminates transmission, both of
which will deactivate all commands and de-energize the crane main contactor.
From this stage the OCU can either be transitioned back to Active mode of switched off.
3.4.4 Transition OCU from Passive to OFF.
From Passive mode, press and hold the STOP button for 3 seconds to power down or if left for 3 minutes it will
power down automatically.
