3.4 KTC composed by more than one transmitting and/or receiving unit
There are also some KTC configurations defined "multiple" which are composed by more than one transmitting
and/or receiving unit. Before using one of these configurations for control a co-ordinate system, it should be
considered in the risk analysis the raccomandations which follow.
The address keys which are used in these multiple configurations must NEVER be used on
other radio remote controls.
Risk analysis has to take into consideration the fact that more than one control station can command the
equipment (or system) at the same time. In fact,
1) when machines are being commanded (see norm EN 60204-1 or 32 par. 9.2.7.5.)
2) when the controlled equipment or working site require it,
it is obligatory to:
- use a measures which ensure that only one unit is transmitting at a time
- indicate visually which control station is controlling the receiving unit
Risk analysis has to take into consideration the fact that a transmitting unit may command more than one
receiving unit at a time. Consequently, it is necessary to take into consideration the possibility that radio
interference and noise may interrupt the link with one or more radio controlled receiving units, causing the loss
of co-ordinate control behaviour.
To wire up correctly:
- use the terminal block s in the KTC units
- follow the schemes and indications given,
-respect all the regulations regarding electrical panels and relevant national laws..
The person who is carrying out the installation must:
- fill in the attached technical data sheet indicating the wiring and connections to both units
- after wiring and connecting the cable to both units, check that the commands or signals transmitted
correspond to those received
- indicate the date on which the KTC was assembled and tested, on the technical data sheet. Sign and stamp this declaration.
In the transmitting unit the actuator contacts wired to the terminals must not be connected
to the power supply.
Wire directly to the safety transformer.
If the use of the equipment requires it, put in a switch to cut out the
power supply (e.g. a keyswitch selector)
COM and CSZ: Common power supply connection in the transmitting unit
Wire the COM to all the commands which may be
a source of risk if they are activated when the unit
is switched on.
