Motor Protection; Error Codes - IKA MTS 2/4 digital Mode D'emploi

While Timer mode is in operation, you can increase or decrease the time
setting as required by pressing the "1" key (6) and/or the "10" key (5)
as described above. After you have changed the time setting, the time
begins to elapse again and the LED display (2) shows the remaining time
in minutes as it did before.

Motor protection

Blocking or overloading the motor beyond the permissible motor tem-
perature causes the device to switch off automatically due to the safety
circuit. The LED display (2) displays the corresponding error message. To
eliminate the error, please check the operating conditions. Also allow
the device to cool off.
The device must be turned off and back on again.
