If a fault occurs, the interface distinguishes between different message types,
e.g. alarms, errors and warnings. The procedure for rectifying a fault depends
on the device. Follow the corresponding instructions in the operating manual
accompanying the constant temperature equipment.
If you are unable to rectify a fault, please contact LAUDA Service,
