IMPORTANT ! The installer of the radio remote control must:
- Carry out a thorough risk assessment on the use of the machine with the radio remote control.
- Assess that there are no hazardous conditions in the event the radio remote control stops due to the loss of the
radio link.
- Do not install the radio remote control on machines in which the safety of moving, lifting or transporting people is
entrusted to the radio remote control with inadequate PL commands.
- Do not install the radio remote control where explosion-proof characteristics are required of the radio remote
control (EX).
- Secure the receiver so that it is always facing the transmitter in normal use.
- Ensure that there are no metal obstacles between the transmitter and receiver or obstacles that may interfere with
the transmission of electromagnetic waves.
- Choose the installation of the receiver in a vertical position and easily accessible for maintenance operations.
- Avoid that the receiver is subjected to strong vibrations. Use vibration dampers if necessary.
- Always make sure that the value of the supply voltage complies with the rated voltage indicated on the rating plate
of the receiver.
- Use multi-pole connectors for the electrical connection of the receiver to the machinery to allow easy removal if
required.
- Use cables of suitable section, max. 1.0 mmq (AWG 16).
- Connect the Stop circuit making sure that the current circulating therein does not exceed the value of the protection
fuse.
- Distribute the common wire to the functions interposing always the Safety relay.
- After installation check that the stop circuit works correctly.
- Check that all limit switches, load or position limiters are working correctly.
- Ensure that all manoeuvres are functioning correctly and are consistent with the symbols placed on the transmitter.
Denition of the key functions:
- Whenever a new match key is connected to a transmitter module, it is necessary
to perform the procedure for the acquisition of the identication code. Press the
Stop mushroom button, bring the keyswitch selector in position 1, press the Start
button for approximately 10 seconds, until the green LED stops blinking. In new
radio remote controls, the identication code has already been acquired.
Switching on and switching off:
- ENABLING THE TRANSMITTER. Check that the Mushroom pushbutton is in rest
position (lifted) and bring the keyswitch selector in position 1. If the receiver is
powered, the transmitter instantly activates a communication channel and the green
LED (Battery Check) ashes fast.
- START-UP. After having enabled the transmitter, bring the keyswitch in position Start
(if applicable) or, in general, activate the START command. Now the green LED
ashes slowly and the system is on. Every transmitted command is now activated
by the receiver.
- SWITCHING OFF THE TRANSMITTER. Press the Mushroom pushbutton or bring
the keyswitch selector in position 0.
Safety function:
- PASSIVE EMERGENCY: In case the receiver can no longer correctly interpret the
signals transmitted by the Transmitter to interrupt the radio connection, the receiving
unit automatically stops, deactivating all the outputs and opening the Stop circuit.
Intervention time of the passive emergency is under 500 ms.
- ACTIVE EMERGENCY: With the radio remote control on, when pressing the
mushroom button the Stop command is transmitted and the receiver turns off all
outputs and opens the stop circuit. Intervention time under 130 ms
- SAFETY COMMAND: The Safety command is transmitted whenever a joystick
is placed outside position zero. This is used to ensure greater protection from
unintended movements with the actuator in rest position (UMFS).
