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.
