The "Start Reflow" button is grayed out if no solder profile has been loaded from the SD card
into the vapor phase.
Lid - lid not closed
Make sure that the lid is closed, otherwise the soldering profile cannot start.
Cooling water temperature too high
The temperature of the cooling water can prevent the soldering profile from starting. To
remedy this, allow the vapor phase to cool down slightly. If this situation occurs consistently,
you can bring cooler air into the vapor phase air inlet. To do this, the air intake is under the
vapor phase soldering unit on the side of the display.
4.6
Cooling water overtemperature
The cooling water temperature of the system is monitored at its hottest point, here there is
a hardware shutdown and a software shutdown. The software shutdown prevents the start
of a profile, the hardware shutdown only takes effect in dangerous situations. For example,
it can happen that during the soldering profile the overtemperature takes effect and the
heating of the vapor phase soldering system switches itself off.
In this case, do not switch
off the vapor phase soldering system.
4.7
Fluctuation of the ACTUAL temperature in the soldering profile
Check if the thermocouple is free-standing in the air or if the tip of the thermocouple is in
contact with metal or the circuit board. If the thermocouple has a thermal mass, then the
detection of the ambient temperature is delayed and leads to oscillation.
