Error Codes
The unit is equipped with an error diagnostics system. This diagnostics system detects errors during the unit ope-
ration and indicates their cause using numeric codes. When an error is detected, an alarm will sound and a war-
ning light will appear on the control panel. The diagnostics system saves the 10 most recent errors detected in the
sequence in which they occurred. This error table can be recalled for viewing.
If you are unable to rectify the cause of the error yourself, contact the Kendro Service and have the error code in
question together with your unit's ID no. ready
NOTE – Activation delay:
In order to prevent brief fluctuations in the operating conditions from leading to error codes being constantly
generated during the incubation mode, the diagnostics system operates with an activation delay:
•
After setpoint changes
•
After opening the glass door
•
For other error sources
NOTE – Resetting the delay time:
If the specified setpoint is reached within the indicated time, the delay time is reset to 1 minute.
NOTE – Error source:
When reducing the temperature setpoint and/or the CO
mosphere may result in the generation of an error message (Code 101/201). Therefore, if the setpoints are being
lowered, the doors on the unit should be opened briefly.
