Visual Check
WARNING !
Always check the sound condition on the transmitter before operating.
¾
Are all the safety devices in the correct position and in good condition?
¾
Are there any broken parts?
¾
Are all of the rubber protections and the actuator covers sound?
¾
Are all of the connecting plugs and cables sound?
WARNING
!
Never work with a Radio Control which results damaged! Always remove any of the above-mentioned faults before
starting to work!
4.6
Safety Control and Start-up of the Radio Control
WARNING !
Important checks on some of the functions mentioned below are required for the first start-up of the Radio Control!
¾
Verify that the transmitter battery casing on the SHW-TX unit also houses a rechargeable battery and that the battery is
connected.
¾
Release the Emergency Stop Push Button on the Transmitter unit, if pressed. Releasing the Emergency Stop Push Button turns
the TX unit on. In RC-PCM or RC-NBM systems it is necessary to engage the radio control with the appropriate pushbutton.
¾
Now, your Radio Control is ready to work. Activate any function on the transmitter unit and verify whether the machine stops
when the same function is released should you release the switch or re-set the proportional actuator to zero.
¾
Now check that the Emergency Stop function works exactly as described by the manufacturer of the machine by applying the
following procedure:
1.
Start any of the functions of the transmitter, verify that the function is activated by the receiver and keep it running
2.
Push the Emergency push button on the transmitter
3.
Verify that the function carried out stops immediately and that no other functions can be then operated from the
transmitter
4.
Was the safety control successful and does the Emergency Stop function work perfectly?
5.
Now release all the control elements
6.
Release the Emergency stop push button, your radio control is now ready to operate in total safety
WARNING !
Should any fault or problem be noticed during the initial starting, turn the machine off immediately. Never operate
the machine unless the Emergency Stop Button functions properly. Serious danger exists for both people and things
from the non-observance of this extremely important regulation. Any operation not conforming to this basic operating
rule may lead to the loss of both the operating permit and your warranty.
4.7
Functions operation
Two possible types of electronic control exist that can be operated from the Radio Control, the digital and analog also named ON-
OFF and Proportional respectively. The ON-OFF control determines either the activation or deactivation of an output stage within the
receiver when the transmitter activates this control. Usually, these are commands that can be sent from push-buttons, switches,
slelectors or digital joysticks.
The Proportional control is a function determining a variable output in either current or voltage in a way which is directly
proportional to the position of an analog actuator on the transmitter, be it a proportional trigger, a proportional rocker switch (PRS), a
potentiometric joystick or a simple potentiometer. Tecnord manufactures different types of proportional controls for several models of
solenoid valves, servo controls or other devices. The transmission technoclogy remains unchanged, while the proportional output stage
of the receiver is designed for the different requirements of the command to be carried out.
4.8
PowerSave Mode and Out-of-service
The Transmitter is powered on when the Emergency Stop Pushbutton is released. In order to reduce power consumption a
PowerSave Mode is implemented. When the Transmitter is powered by batteries and no function is activated for five minutes the
system goes into a “PowerSave” mode: the led is switched off and the RF module is no longer active. In order to operate it is necessary
to press and then release the Emergency Stop Pushbutton.
When the Transmitter detects a low value on the batteries the led blinks indicating that battery charging is required. When the
battery level is below the threshold for safe operation the system goes out-of-service: the led is switched off and the RF module is no
longer active.
