Manual ULTRA Guard 430 - English - Rev 7 - Optional LED 6
Company Registration Number 1015471
Warranty
The device is suitable for use with all FBL controllers. Device will be damaged if polarity connected
incorrectly. If used with third party lithium pack, only use JST-XH connectors and NEVER connect the
lithium pack to the RX or FBL controller directly.
Warranty is 12-months from purchase date.
Voltage range over which the system works:
Beware:-
 Do not connect UG430 plug into a device with reversed polarity this will damage the UG430.
 Set up your BEC/ESC before you connect the UG430 to your system for the first time.
Thereafter the UG430 can be left connected unless you decide to change the BEC voltage. In
this case remove the UG430 plug from your system until you have reset your BEC/ESC voltage
then reconnect. The UG430 will then re-learn the system voltage.
 Remember this device reacts to “VOLTS”, so if you move your servo’s this might mean the
board comes to life but unless more than 4V is seen for 5-seconds it will not arm.
 Some components on the HV board do get hot in use this is usual.
 DO NOT install and then test it on a BEC that is not capable of taking a back feed voltage. This is
a safety device to drop in and supply voltage in the event your BEC fails or Regulator fails such
that you have power to land buy having control of the RX/FBL unit and power to servos. If you
wish to test on model then power up the system and allow the UG430 to set if using a BEC
isolating it such that the UG430 cannot back feed into the BEC (remove lead from BEC so power
to system) and the UG will switch in. BEFORE you reconnect the BEC turn off the UG430 so it
will not back feed into the BEC and it will relearn the system voltage and then reset.
REMEMBER THIS IS A SAFETY DEVICE TO SUPPLY POWER IN THE EVENT OF A POWER SOURCE FAILURE.
