Operating instructions

Turn the main switch on. This will initiate the electronics.
Four dots will sequentially blink to indicate the start-up.
Next the top display will show 1P (1-phase). The lower
display shows the supply frequency 50 or 60 Hz.
When the start-up sequence is over, the displays show
the active curing times in minutes. Flash-off at the upper
and full bake at the lower.
Use the + and - buttons below the displays to change
the settings. Pressing the buttons continously will rapidly
increase the setting. Each timer can be set between 0
and 30 min. The settings will remain even after power-
off and serve as default for the next curing operation.
Start the curing by pressing the On/Off button. The ac-
tive timer will flash and the heater will switch off auto-
matically when the set times have elapsed. The cassette
fan will run for another 3 minutes for cooling down.
After idling for 30 minutes, the unit enters stand-by
mode when a dot in each display flashes. Pressing any
button will activate the unit again.
NOTES:
- The FLASH OFF timer controls the duration of the half
power output of the emitters. The FULL BAKE timer
controls the duration of the full power output of the
emitters. If both FLASH OFF and FULL BAKE timers are
used, the FLASH OFF timer will count down first and
upon switching off it will engage the FULL BAKE timer
automatically.
- To stop the unit before the time is out, press the On/
Off button.
- Altering timers is possible even during curing.
- If the temperature inside the control unit rises over 65
°C (149 °F) , the unit switches off. The upper display will
show Ot (over temperature) and the lower the actual
temperature. Automatic reset when the temperature falls
below 55 °C (131 °F) and the unit is ready for operation
again.
