Brief Troubleshooting
Touch screen is blank
To maximize the touch screen optics, the touch screen will go into screen saver mode after being un-touched
for 30 minutes. To re-activate the touch screen (while the unit is still on), simply press anywhere on the
screen and the screen will illuminate. The power indicating light (illuminated blue ‘O’ in CARON) indicates
when the unit is on.
Chamber is alarming (see also alarm section of manual)
At the alarm screen, what alarm is indicated?
Was the alarm condition rectified?
Was the acknowledge alarm button pressed?
Has another alarm appeared in the alarm screen?
A ‘Lamps too hot’ alarm can’t be silenced until the lamps cool down to acceptable levels. To cool
down the lamps, turn unit off and open the door for 1 hour. If problem persists, contact service
personnel.
A ‘Lights dim’ alarm can also be reset by having the lights on at an intensity above the alarm level
for 1 minute.
Interior lights won’t come ‘on’
Are lights turned ‘on’?
Is light test ‘complete’?
Are any alarms activated? Silenced alarms are reset when unit is turned off.
Is door safety switch enabled?
Is correct light bank inserted?
Is light bank pushed in all the way?
Are the lamps inserted correctly?
Are all the lamps installed? If one lamp is not installed properly or burned out, it will affect the
performance of other lamps.
Interior lights have lower intensity than expected
Are all the lamps installed and on? If one lamp is not installed properly or burned out, it will affect
the performance of other lamps.
Are the lights dimmed?
Is there a light calibration factor applied?
Is something physically between the lamps and light detector?
Do the lamps need replaced?
Unit won’t reach temperature set point
Has the unit stabilized for 1 hour?
Is the temperature set point within the unit specification range?
Is the ambient temperature between 20ºC-25ºC?
If set point is above 25ºC, are the lights on?
