OPERATION & MAINTENANCE INSTRUCTIONS
IMPORTANT NOTICES
The security ‘i-Key’ that accompanies your Pendant Station (PS) controller has been pre-programmed
with certain system operating parameters before leaving our factory. If your PS controller is of the
Advanced Technology (AT) family that is custom built to your specification, such ‘i-Key’ parameters
will include a specific address and operating frequency. However, CATTRON-THEIMEG™strongly
advises you to check that our pre-configured address and frequency is not duplicated in other remote
control equipment located at, or around, your operating facility.
When returning an PSAT Pendant controller to CATTRON-THEIMEG™for repair, the original coded
‘i-Key’ supplied with the unit shall be returned with the unit.
When returning a PSEZ or PSCS Pendant controller to CATTRON-THEIMEG™for repair, we
recommend the coded ‘i-Key’ last used with the unit be returned with the unit.
Before returning a PSEZ or PSCS Pendant controller to CATTRON-THEIMEG™for repair, we
strongly recommend you record the operating address and frequency assigned to the controller as you
will be required to re-program these operating parameters after we return your controller. Refer to
Frequency and Address Reports in Section 5 of this manual for recording details.
When a PSEZ or PSCS Pendant controller is returned to CATTRON-THEIMEG™for repair, we make
every effort to establish the operating address and frequency assigned to your controller when it arrives
at our repair facility. Whenever such operands can be established, we will record the same on the
service documentation returned with your controller.
This equipment is firmware based. Any duplication of operating firmware without written consent of
CATTRON-THEIMEG™is prohibited. U.S. Copyright Laws protect all firmware, parts and product
listings, assembly files, and this manual.

Section 1 –Product Data & Specifications
Functional Description.
The CATTRON-THEIMEG™Pendant Station (PS) remote controller is a lightweight, extremely rugged
customizable radio control unit for use with any CATTRON-THEIMEG™Portable Remote Control
(PRC) System. CATTRON-THEIMEG™PS controllers are offered in three family configurations:
PSEZ (Easy), PSCS (Crane Specific) and PSAT (Advanced Technology).
In all three CATTRON-THEIMEG™families of PS controllers, operational security is advanced to its
maximum by the use of a removable stainless steel, electronic ‘i-Key’ which, when installed in the
controller, defines and enables the appropriate operating parameters. When the ‘i-Key’ is removed, the
controller is totally disabled. It should be noted that each family of PS controller has a specific colored
‘i-Key’ (green = EZ, blue = CS, and silver = AT) and that these ‘i-Keys’ are not interchangeable
between controller families.
The switch unit and electronics are contained in an extreme duty, water and dust resistant, aluminum
housing which has armorized rubber end-caps for switch protection and high impact resistance. The
controller housing is ergonomically designed with curved bottom and rubber side grips to allow
comfortable handling. The ‘i-Key’ is mounted in a receptacle located within the confines of the
armorized rubber ‘bumper’ that forms the top end-cap. Separate Power ON/OFF and STOP (red)
switches are also located next to the removable ‘i-Key’. The controller front face contains up to six
large pushbuttons that are engraved with their respective control function symbols. When pressed, each
pushbutton activates circuitry inside the controller. Pushbuttons may be of three-step or proportional
(stepless) operation.
Three-step pushbuttons provide 3-speed operation with a single pushbutton. When pressed, each
pushbutton step has a distinct limit of travel that provides an enhanced tactile feel that is noticed by the
operator.
Proportional (stepless) pushbuttons provide variable frequency drive (VFD) operation with a single
pushbutton. In these applications, the drive motor speed is directly proportional to the amount of travel
of the pushbutton (more distance = more speed).
Additional maintained and momentary depression toggle switches are mounted within a recessed
channel alongside the large control function pushbuttons. Note that PSAT models may be provided
with variety of custom switches
All commands from CATTRON-THEIMEG™PS controllers respond within milliseconds of pressing or
releasing a pushbutton. Additionally, a mainline ON command is sent when power is turned on and re-
sent anytime a controller function pushbutton is pressed. Within the PS controller, a microprocessor
performs self–diagnostics, interprets pushbutton and switch commands, and controls the radio
transmitter.

Section 1, Page 201/2001, CATTRON-THEIMEGTM
Functional Description, continued.
CATTRON-THEIMEG™ PS controllers are equipped with an internal antenna and the typical operating
(transmitter) range is in excess of 500 feet (160+ meters). It should be understood that operating range
varies with environmental conditions. Should the transmitter go out of operating range, all motions will
cease.
CATTRON-THEIMEG™ PSAT series controllers have been approved to comply with both FCC Part 15
(non-continuous transmission) and FCC Part 90 (continuous transmission) applications, and for DOC
RSS-210 (non-continuous transmission) and RSS-119 (continuous transmission) applications standards.
No United States of America FCC, or Canadian DOC license is required for operation of FCC Part 15 or
RSS-210 (non-continuous transmission) PS controllers. Non-licensed PS controllers transmit the very
secure CATTRON-THEIMEG™ Series digital message, using frequency modulation (FM) radio. These
radio transmitters are approved for use on frequencies between 425-447MHz (M) and 447-473MHz (H).
They can be used on any frequency within these bands, including normally licensed channels without
the need for a license.
An authorized station operating license is required for the operation of US Part 90 and Canadian RSS-
119 (continuous transmission) applications. If you need assistance in obtaining these licenses, please
contact CATTRON-THEIMEG™ Inside Sales Department in the first instance.
As previously mentioned, operational security is maximized by the need to use a stainless steel
electronic ‘i-Key’ for controller operation. However, there is an additional and very significant
operational advantage of the CATTRON-THEIMEG™‘i-Key’ concept. It is that individual system
address, operating frequency and keypad configuration may be permanently stored in the ‘i-Key’,
depending on the type of controller supplied. Therefore, CATTRON-THEIMEG™PS controllers
belonging to the same family at a user location can be identical -only the ‘i-Keys’ are different. To
simplify, each ‘i-Key’ is color-coded and labeled for an individual control system family, thus, any
CATTRON-THEIMEG™PS controller will run any CATTRON-THEIMEG™receiver/decoder
belonging to the same family as long as the correct ‘i-Key’ is used. As the result, this unique operating
concept reduces the need for specific spare remote controllers. Our unique family of PS controllers is
identified on the next page.
All CATTRON-THEIMEG™PS controllers are powered by disposable 3-Volt alkaline or re-chargeable
Ni-Cad battery packs. In normal operation, a green LED ‘flashes’ with each function command message
and a ‘beep’ is sounded when a pushbutton is depressed. When the battery voltage becomes low, a
separate yellow LED flashes, alerting the operator that the battery pack needs to be replaced or re-
charged soon. Battery packs are easily and quickly replaced without the need for tools by turning two
knurled thumbscrews and removing the battery cover-plate located within the confines of the armorized
rubber bottom end-cap. The battery pack makes positive contact without snaps or plugs and has no
wires to break; simply drop it in, and replace the battery cover-plate.

01/2001, CATTRON-THEIMEGTM Section 1, Page 3
Functional Description, continued.
Ni-Cad battery packs can be re-charged ‘in-situ’ and do not need to be removed from the controller
housing. To enable such battery charging to be carried out, a series of optional battery chargers are
available for all CATTRON-THEIMEG™PS controllers. One end of the charger is connected to the
mains power outlet, the other plugs into a covered socket located within the bottom end cap. Additional
options include an ‘AAA’ size battery adapter, and an external battery-charging unit –refer to
accessories/consumable items in Section 6 for details and part numbers.
A shoulder-carrying strap is standard for all CATTRON-THEIMEG™PS controllers. This is quickly
and simply installed to a pair of ‘D’-rings located on the side of the controller.

Overview –CATTRON-THEIMEG™Remote Control Systems.
Figure 1-1 below shows a simplified block diagram of a typical CATTRON-THEIMEG™remote control
system. Refer to this figure and the following paragraphs for a functional description of the remote
control system.
The target receiver/decoder is controlled by the Pendant Station Controller. Provided the correct
coded ‘i-Key’ is inserted into the controller, the controller sends signals to the receiver/decoder using an
UHF radio link. The signal is picked up by the antenna and passed on to the receiver. If the signal is the
correct frequency and passes all required data tests, the signal is passed on to the decoder. The decoder
compares the address code of the signal to its own address code. If the signal’s address code does not
match its address code, it is ignored and a message is displayed on a system status display located in the
receiver/decoder unit. If the address code is correct, the decoder processes the message and energizes
and de-energizes the appropriate control, directional output, three-speed and auxiliary function relays
located within the control system.
An Automatic Safety Override (ASO) function continually monitors the state of all directional relay
outputs (i.e. Forward/Reverse). If a directional relay electrically fails closed without a command from
the controller, the ASO circuit logic de-energizes the master output relay (OPR).
During operation, the microprocessor on the decoder board resets multiple watchdog timer circuits
whenever valid messages are received and decoded. If the microprocessor fails to reset the watchdog
timers, the timer circuits shut down and de-activate all relay outputs. The decoder microprocessor
requires continuously valid transmitted signals to be received and decoded or all relay output functions
will be de-activated unless programmed otherwise. It should be noted that the mainline control relay
(OPR) would be maintained for up to 10 minutes, depending on system configuration.
