Introduction
Maximum number of
TSX CFY • 1 modules per station
Step-by-step axis command modules can be installed in any slot of a TSX RKY•• rack. The rack power supply must be chosen according to the number of modules installed.
l l
Each step-by-step command module supports:
1 application-specific channel for TSX CFY 11 module,
2 application-specific channels for TSX CFY 21 module.
Since the maximum number of application-specific channels managed by a PLC station depends of the type of processor installed, the maximum number of l l
TSX CFY •1 modules in a PLC station will therefore depend on: the type of processor installed, the number of application-specific channels already used other than step-by-step command application-specific channels.
You should therefore make a global report at PLC station level to find out the number of application-specific channels already in use and thus define the number of
TSX CFY •1 modules which can be used.
Reminder of number of application-specific channels managed by each type of processor:

Installation procedure
General The module can be installed or removed without cutting the rack power supply, to ensure that a device is available.
CAUTION
Connection and disconnection of connectors
It is not recommended that you connect or disconnect the connectors with the translator power supplies, as some translators cannot cope with this action. The auxiliary input/output connector can be disconnected while switched on without damaging the module.
However, for safety reasons it is recommended that you turn off the auxiliary power supply before any type of disconnection.
Failure to follow this precaution can result in injury or equipment damage.
The module fixing screws and connectors must be correctly screwed in place in order to guarantee effective resistance to electrostatic and electromagnetic interference.

General precautions for wiring
General The power supply to sensors and actuators must be protected against overload or overvoltage by fast-blow fuses.
l l l when wiring use wires of sufficient size to avoid on-line voltage falls and overheating, keep sensor and actuator cables away from any source of radiation resulting from high-power electric circuit switching, all cables connecting the translators must be shielded, the shielding must be good quality and connected to the protective ground both for the module and the translator. Continuity must be ensured throughout connections. Do not transmit any other signals in the cable than those for the translators.
For reasons of performance the auxiliary inputs of the module have a short response time. You must therefore make sure that there is enough self-sufficient supply to these inputs to ensure the module continues to operate correctly in the event of a short power break. It is recommended that you use a regulated supply to ensure more reliable response times from the actuators and sensors. The 0 V supply must be connected to the protective ground nearest to the supply module output.
