voltage, short the pin designated "Down" to the center pin momentarily. If you
hold the pins shorted for longer than one second the voltage will increase or
decrease at a rate of about one quarter volt a second.
Servo Power LEDs
The servo power LEDs show the servos are getting voltage greater than 5.4V.
If the regulator output drops below 5.4 volts the LEDs will go out. The most
probable cause of the regulator output going below 5.4 volts is that the voltage
at the inputs (Deans connectors) is going below 5.9 volts. Possible causes of
the inputs going below 5.9 volts would be low batteries, wiring that is not up to
handling the current causing excessive voltage drop or bad solder connections
on the connectors.
Receiver Power LEDs
The receiver power LEDs show the receiver is getting voltage greater than
4.75V. If the receiver regulator output voltage drops below 4.75 volts the
LEDs will go out. There are two possible causes of the receiver voltage going
below 4.75 volts. First the load the receiver is presenting to the regulator is
greater than one amp causing the regulator output to droop. This could be
caused by directly plugging something into the receiver that is overloading the
circuit. The second cause of the receiver regulator going below 4.75 volts is
the input voltage to the receiver regulator has dropped below 5.4 volts. This
means the input voltage on the Deans connectors is probably below 5.9 volts
for some reason.
Optional Failsafe-switch
The PowerSystem Competition 12 supports the addition of a failsafe switch
(optional package). The PowerSystem Competition 12 supports 2-cell lithium
packs, ion or poly. When using the failsafe-switch, the switch lead is plugged
into the input marked "Sw" near the bottom left of the servo connections as
shown on the reference drawing.
Smart-Fly can supply two types of failsafe switches. First is the standard slide
switch that most people are familiar with. This is a small slide switch without a
charge jack. The second failsafe-switch is the Pin&Flag switch, where a pin,
with a flag on in, is inserted into the switch to turn the system off. To fly, the
pin is pulled out of the switch. The advantage of the Pin&Flag switch is that the
system cannot accidentally be turned off, as can be the case with a slide
switch. The failsafe switch lead can be extended using a standard Futaba
extension.
The PowerSystem Competition 12 also supports charging the batteries through
the two charge connections denoted by the "Chg 1" and "Chg 2" next to the
battery input ports. The optional failsafe-switch package includes two charge
leads and two Ernst charge jack mounts. The charge leads have a Futaba
male on one end and a JR male on the other end. You may use these by
plugging either end into the PowerSystem Competition 12 and the other end
into the charge jack holder.
The charge jacks on the PowerSystem Competition 12 can also be used to
connect to a battery meter. One thing to keep in mind when using a battery
meter and the failsafe-switch is that the jacks are not switched off when the unit
is off so the battery meter will continue to draw power even when the unit is
turned off.
Ignition Cutoff
A separate manual, "PowerSystem Competition 12 Ignition Cutoff User Guide"
is supplied to instruct you on the setting up and use of the Igntion Cutoff. The
Cutoff channel is assigned using a jumper from the receiver channel (on the
receiver or servo output on the Competition 12) you want to control the Ignition
Cutoff to the Ignition Cutoff control input marked as "IC" on the unit.
Calculating The Servo Regulator's Current Capability
The actual continuous current the servo regulator can handle is based on both
the input voltage and the output voltage. The regulator's 17.5-amp current
handling is based on an input voltage of 8.4 volts and an output voltage of 6.0
volts. If you have some other combination of input and output voltages you can
calculate how much continuous current the regulator can handle.
maximum amount of current the regulator can supply is about 35 amps even if
you calculate you can handle more continuous current based on your input and
output voltages. You can use the following formula where Vin is the input
voltage and Vout is the output voltage and Ic is the continuous current
capability:
Ic=42/(Vin-Vout)
An example might help clarify this. If you were using a 3-cell lithium pack in an
electric, the fully charged voltage of the pack is about 12 volts. If you set the
output voltage of the regulator at 6 volts then, using the equation:
Ic=42/(12.0-6.0) =42/6.0 = 7.0 amps
