MICROSENS GLOW2C
Glow driver for 1 – 2 cylinders
Warnings
Read carefully this manual first before you put the electronis into operation.
Observe all warnings and hints of the engine and battery manual too.
General
This electronics is intended for heating of model engines glow plugs. It works with all
standard RC receivers. The glow battery should be a 2S LIPO.
All plugs are controlled seperately and each plug has an own monitoring red LED.
The brightness of the LED shows the glow current of this LED.
If one plug is broken, this LED will be off and all others will work normally.
Like the former GLOW_LP it works in two modes : Starting mode to start the engine
and after that the running mode.
Starting mode : Full glow strength, the glow plugs light orange.
Running mode : Half glow strength in idle postion or less up to half speed.
Above half speed no glowing.
At idle the glow plugs are still dark, though they are heated.
Detecting of wet plugs : A common problem of radial engines is that the lower plugs are
getting wet after a long idle run and turn off the glowing. The GLOW2C detects a
wet plug and increases the current of this plug as long as it is wet.
Connectors
The glow plug leads
are connected by terminal strips. The leads shall have an isolated crimped bootlace on the
end. The recommanded copper diameter of the cable is 0,75mm².
The glow plug lead should be connected with a screw on the glow plug and not with a
spring, this contact is too poor and the detection of a wet plug wo'nt work properly.
Best choice is to use MICROSENS ZUBI3.
The terminal strips are easy to open if you put a 3mm screwdriver with some force into the
slit above the cable opening.
One connection is for one glow plug only and avoid a short crcuit between two glow plugs.
The outputs are short circuit protected against ground. If a short circuit happens, this
output will switched off until the next power on.
The ground connector M should be connected with a 0,7mm² copper diameter cable to the
engine housing.
Glow battery connector :
Use a 2S-LIPO (=7,4V nominal voltage) battery with more than 10C. A typical capacity
value for 2 glow plugs is 1000mAh, this is usually enough for 2-3 flights.
Attention : Check the correct polarity of the battery before you connect it at the first time.
A wrong polarity will destroy the electroncs and all connected glow plugs!
There is no warranty in this case.
The servo connector
is a JR type, suitable for all standard receivers. The approbiate receiver battery voltage is
4,8V – 8,4V. Do'nt use it with a higher or lower voltage.
