Sidus - electronic timer
10/11
Installation notes
Hall sensor
Insert the sensor in the hole located in the bottom of the magnetic
start switch as shown in the picture. Do not put it upside down.
Glue it to the start switch with silicon sealant or epoxy.
Should it be necessary to extract the plug at the other end of the sensor cable, do
not pull it through the wire. The connector plug has small protruding edges that
must be grabbed with tweezers (or with the finger nails) to gently pull the plug out
of the socket
Control board
Place the control board with the IR sensor and the leds close to the front-end side
to have them clearly visible through a small clear plastic transparent window. All
wires and connectors must be laid in a clean way with no mechanical tension.
Avoid firm fastening of the Timer control board to the fuselage. Use foam rubber in order
to minimize possible malfunction caused by high frequency vibrations.
Battery and recharge connector
Provide easy access to the battery pack and to the recharge connector anytime to
disconnect or recharge the battery when needed. The battery pack ensures about
80 flights of 180 seconds each. Do not recharge it too frequently, just refresh it
from one flight session to another. If you are not going to fly the model in a few weeks it is
recommended to disconnect the battery pack.
Mechanical assembly
For the “SE” type assembly use a thin rubber gasket under the faceplate to fasten
the mechanical assembly to the fuselage. It is also recommended to use a rubber
gasket (O-ring) between the faceplate and the bottom of the head of the fastening
screws. For the “VE” type assembly refer to the specific instructions.
RDT antenna
Fasten a 175 mm. long (0.4 - 0.5 mm diameter) steel wire vertically to the top of the
fuselage: this will be the RDT antenna. It must be electrically insulated from carbon or
conductive parts through a Teflon or Nylon spacer. Inside the front-end, connect/solder
the antenna to the flexible cable supplied and solder the other end of this cable to the
RDT antenna plug, also supplied. Plug this cable to the RDT socket on the mother board
(see picture
1
). Failure to follow the above will result in a poor range of the whole RDT
system.
Note that when testing the RDT system on the bench, it may be needed to move
the Programmer a few meters away to operate correctly.
