During operation, the EDA 500 can display different messages. The following messages can occur:
EDA2
No communication
between the IINOVA 500 and EDA2 smoke head. Check the communication
OFF-LINE
cable connection. Check that the EDA2 is switched on.
EDA2
The smoke cell temperature is below 80 ºC. The smoke cell is heating up.
HEATING
ERROR
This message can occur during a zero calibration. Reason for the error can be:
a) Receiver needs to be cleaned, see Chapter 12.
b) The halogen light source is defect, see Chapter 12.
c) The smoke head is located in a location with to much direct sun light.
Move the smoke head to another location.
6 Maintenance
Cleaning
Clean the outside of the INNOVA 500
and smoke head with a soft towel and eventually with a non aggressive liquid
like Glassex. Before cleaning the unit always switch off the INNOVA 500
and remove the mains plug. Let the smoke
head cool down till ambient temperature.
Replacing the printer paper
Open the printer by pulling the lit at the cover forwards. Remove the old roll and place the new roll in the printer. Let
a piece of paper of approximately 10 cm hang out of the printer. Press with both hands at the printer cover to close
the printer. Press a the paper feed key to check the paper transport.
Replacing the fuses
Before you change the fuses always switch off the INNOVA 500, remove the power lead and let the smoke head
cool down until ambient temperature. Open the little lit of the main switch at the rear of the EDA, no. 12 of figure 2.
Take out the fuses and place the new fuses in the holders of the lit. Use 230 V 2AT fuses. Close the lit.
In the smoke head the fuse holder is located at the bottom of the EDA 2, no. 5 of figure 3. Press and open the
holder by turning it counter clockwise. Take of the holder with the fuse. Replace the fuses. Use 230 V 2AT fuses.
Close the fuse holder by pressing it and turning it clockwise. If you have to change the fuses frequently, please
contact our service department!
Calibration
The EDA 500
must be calibrated once every 12 month. The calibration can only be performed by authorized
technicians from your supplier. We advise you to take a service contract including the annual calibration.
Cleaning the optical components of the smoke head
If the receiver gets polluted, the receiver voltage will go down and the smoke meter will show ‘ERROR’ during a
zero calibration at the displays. Switch off the INNOVA 500
and let the smoke head cool down until ambient
temperature. Loosen the right mounting ring of the smoke chamber and take out the cone. Now take the receiver
support out of the cone. Clean the front surface of the receiver with a clean and soft cotton towel. Don’t touch this
surface, the lens, with your fingers. Put the support back to its position and place cone into the smoke chamber.
Tighten the mounting ring. Switch on the smoke meter and perform a zero calibration. Check that the smoke meter
is not showing the error message again.
