I can find two options for the ZD-915 I don't yet have the unit but I already see the old style 915 gun has some issues and still has a plastic tube solder waste chamber.
So I want to buy a ZD-8915 gun (with glass tube) alone for spare so I can replace it but what is really hard to figure out is if they will work on the ZD-915 (even the web shop selling it can't tell me).
You have two different styles of DIN alike connectors which are called Aviator sockets.
The difference are 6 pins and one has 7 pins. I looked at the garbage manuals and was able to find only ONE in a video that showed the pin-out on yt.
Here's the manual of the 7-pin Pro'sKit SS-331 gun 5SS-331N-DG (90 watts variant vs zd-915 80 watts):
7 Pin connector (gun) pin-out:
- [pin 1 & 2] sensor (PTC/Thermistor) 50Ω±3Ω (25°C room temperature)
- [pin 3 & 4] heating element 2Ω±1Ω (25°C room temperature)
- [pin 5 & 6] trigger switch - 0Ω (trigger on)
- [pin 7 & 2] open or 0Ω (shaking gun) sleep tilt switch?
Just measured my ZD-915 24v 80W gun,
6 Pin connector (gun) pin-out:
- [pin 1 & 2] sensor (PTC/Thermistor) 1.6Ω(±3Ω?) (24,3°C room temperature)
- [pin 3 & 4] heating element 1.4Ω(±1Ω?) (24,3°C room temperature)
- [pin 5 & 6] trigger switch - 0Ω (trigger on, test with continuity mode)
So the only difference seems to be that one model has a tilt sensor for sleep mode so it won't burn your heating element up faster and the other one just burns the heater up no sleep mode? And obviously a bigger heating element with more thermal mass and bigger heater?
Can one confirm this also is it possible to use the bigger heater on the ZD-915 or the gun from the ZD-8915 (SS-331) on the ZD-915, because there seems to be an option to order ZD-8915 gun with 6 pin and 7 pin aviator connector.
It would be cool if one can answer the question, because I don't know there are so many rebrands and make and models none of them describe it properly or have a nice detailed manual..
