ROUBLESHOOTING

Incorrect operations are often mistaken for malfunction. If you think that there is something wrong with a

component, see the troubleshooting scheme below. If the problem persists even after troubleshooting as

described below, please ask for Okolab support

Symptom

Probable cause

Remedy

Device off

Supply cable disconnected

Properly connect the cable

Supply cable damaged

Substitute the cable

Blown fuse

Replace the fuse (see Technical Specifications)

No temperature displayed or

“nan"

Thermocouple cable disconnected

Properly connect the cable

Thermocouple cable damaged

Contact Okolab to receive assistance

Embedded sensors damaged

Contact Okolab to receive assistance

Chamber Base and Lid cold

Low set point value

Change the set point

Heater 1/2 and/or cable disconnected

Connect the cable

Heater 1/2 and/or cable damaged

Contact Okolab to receive assistance

Heating elements damaged

Contact Okolab to receive assistance

Alarm rings (for specimen

temperature feedback)

Chamber Base at high temperature (for

specimen temperature feedback)

Quickly shoot down the control unit and properly

set the system. Please, check below

Chamber Base at high

temperature (for specimen

temperature feedback)

Control thermocouples connection

Check the connection scheme

Damaged thermocouple

Ask Okolab for replacement

Sensor out of the reference well or

chamber open

Make sure that the thermocouple is correctly

positioned in the reference well and that the

incubating chamber is closed (if working in

“Specimen Control Mode)

I check the previous

troubleshooting but I cannot

solve the problem
