TK80 Smoke issue

Help

My TK80 board on testing there was no smoke checking the board pins CN10 and CN11 there is no voltage on the pins looking at the diagram am I supposed to supply battery power to them or not?

See the attached TK 80 manual; everything is explained clearly in the section "Connector and pins assignment, It seems, from what has been mentioned, that there is an "inter" socket that needs to be activated?

Hi

Read the manual can’t get my head round what needs doing hoping someone has done this to explain a bit easier to understand no idea what an inter socket means

Hello
So, unless I'm mistaken? CN 10 is the power supply for the smokehouse heater, and CN 11 is the switch that controls the system's On/Off function. There's only one battery to power the entire circuit board and all the tank's functions. If you scroll down further on the page linked below, there's a photo of the "HL Smokehouse" and text explaining everything that can be done with it.

It’s a TARR smoke unit has separate fan and heater cables surely as the on off control is on the transmitter signal (SWA) and the board has battery power already connected surely this should provide power to the heater but as stated the fan starts up and shuts down correctly with SWA switching but there is no power on the pins for the heater in any state, as far as I can tell it’s a software switch signal so surely the board has power it should power the heating element Heng long boards can manage it?

The TK80 can independently control the fan/pump and heater for a more realistic smoke effect. It begins heating the heater to generate smoke as soon as the engine start command is given and smoke accumulates in the chamber. Upon engine start, it runs the pump/fan at full speed to create a smoke explosion like a real engine, then operates the pump/fan proportionally to the throttle. When the engine stop command is given, it stops the fan/pump and the heater.

To control the fan/pump and heater separately, you must also disconnect the fan/pump and heater wires from the original HL smoker and connect them individually to the TK80. To do this, simply desolder the heater wire (red-red) from the smoker's circuit board and connect it to port CN10. Connect the pump motor to port CN12 (original black-red wire). Finally, connect a switch to port CN11 to enable/disable the heating control from the TK80. The video below shows a modified Hen Long smoker, controlled by a TK80.

Previous message? With on/off control.
CN 10: Smoke system power supply
CN 11: On/off switch
2nd solution.
Smoker assembly on CN 12: it's the TK 80 that manages it, perhaps some programming is needed?
The TK 80 documentation shows an HL smoker? Personally, with a Taar, I don't think it changes the wiring much. 4 wires, 2 resistors, and 2 fans, all connected together on CN 12.

Hi

Thanks for all the replies I’ve emailed Clark as far as can tell CN12 is proportional so the voltage raises and lowers which I don’t think will be any good for the heating element I’ll see what they say a not sure when they say on/off switch when it’s controlled from the transmitter

[Jofaur86]

The on/off switch is for situations where the system isn't controlled by the radio, but rather by a small (black and fragile) switch, usually located under the commander's hatch. If you want it to be independent of CN 12 and therefore not proportional, you need to use a free output on the receiver and connect either a servo with a contact or a direct electronic switch.
So you can start the smoker and then stop it, because it draws a lot of current from the battery (just FYI).
