your oven, boards and parts density etc.
Place the reflow oven on a hard, level and heat resistant surface. Do
not cover any holes in the oven housing – the airflow is necessary,
damage to the oven and/or your PCBs will result if airflow is impeded.
Always allow the oven to cool to below 50 degrees (as reported on
the display) before stopping the cycle or attempting to remove the
boards from the drawer. Do not stop a reflow cycle and begin
another without first allowing the oven to cool to near ambient air
temperature.
Never start a reflow cycle with hot PCB(s) - allow to cool first.
Ensure adequate ventilation in the work area, air extraction is
essential if working in a confined space.
Place boards to be soldered centrally in the drawer of the oven. If a
small board is being soldered, it is best to position this below the
thermocouple towards the front of the oven. This will provide the
most accurate temperature control. Always ensure there is PCB
below the oven thermocouple.
Reflow Controller Installation Troubleshooting
Issue
Cause
Solution
Controller does not
power on when oven is
switched on
Incorrect connection of low
voltage AC supply to
controller
Check connection of low voltage AC power
supply to the ESTechnical Reflow Controller.
Mains power is not supplied
to the 9V transformer
Check the primary winding of the 9V
transformer is connected between the
switched live feed of the oven and the neutral
terminal
Fan or heater does not
work during a reflow
cycle
Incorrect connection of signal
cable between Reflow
Controller and SSR
Check the polarity of the connection and
correct if necessary, the polarity is marked on
the controller and the SSR terminals
Incorrect mains power or SSR
connections
Check the connections between the mains
power, SSRs and loads (heater and fan) are
made as per the instructions
DC cooling fan does not
start
Incorrect connection of the
DC cooling fan to the
ESTechnical Reflow Controller
Check (and possibly reverse) the connection
on the controller to the DC cooling fan, the
wiring colours used by the original oven
manufacturer are inconsistent and can be
misleading
LED indicators do not
light during a reflow
cycle
Incorrect polarity connection
of the LEDs to the
ESTechnical Reflow Controller
Check (and possibly reverse) the connection
on the controller to the LEDs, the wiring
colours used by the original oven
manufacturer are inconsistent and can be
misleading
