Safety Considerations.
CATTRON-THEIMEG
™
believes that to safely operate any remotely controlled equipment, the overall
system needs to be configured so that movement or operation of the equipment will take place only
when the device is commanded to move or operate. For example; overhead cranes must be equipped
with a braking system, which can only be released when an electrical signal is sent to the motor.
Removal of electrical power or loss of the radio transmitted signal results in application of the brakes.
One way to accomplish this is with a CATTRON-THEIMEG
™
Electro-Hydraulic brake package –
contact the factory for details.
In keeping with this philosophy -
NO COMMAND, NO MOVEMENT
- CATTRON-THEIMEG
™
has
designed your radio remote control system with the following safety and security features.
‘i-Key’
: Operational security is advanced to its maximum by the use of a removable
stainless steel, electronic,
‘i-Key’
which, when installed to the Pendant controller, defines
and enables the operating parameters. When the
‘i-Key’
is removed, the controller is totally
disabled.
Unique address code:
Each PS series controller and receiver/decoder pair is configured
with a unique address code so that the equipment will respond only to the controller whose
address code matches that of the decoder.
Intelligent digital message protocol:
CATTRON-THEIMEG
™
remote control systems
utilize a unique message protocol for industrial control applications rather than the
customary Electronic Data Processing (EDP) type of message format.
ON/OFF power switch:
The PS controller is provided with a rotary power ON/OFF switch
that must be set to ‘ON’ in order to send commands to the receiver/decoder. If the power
switch is set to ‘OFF’, the decoder will remove all commands from the controlled
machinery, stopping all movement. However, the mainline control relay (OPR) will be
maintained for up to 10 minutes, depending upon system configuration.
Red System STOP Switch:
Operating the red STOP switch while the PS controller is
turned on will repeatedly send a burst of stop commands to all outputs including the
mainline control relay (OPR).
Operate relay (OPR):
The operate (OPR) output relay shall be wired to control a user-
provided electro-magnetic power contactor. The electro-magnetic contactor opens and
closes the main electrical supply circuit(s) to the controlled device.
Data Error Checking:
All communications from the Pendant controller to the
receiver/decoder contain error-checking information (BCH data error detection routines).
The entire data command packet must pass error detection tests before being processed.
