Function control with visual and acoustic alarms
8.4
The temperature controller is equipped with an electronic function control. The following features are supervised: the
switching contact of the low water cut-off, the pre-set values for over- and under-temperature alarms (see chapter
8.2.2), and the temperature sensor B1 (see chapter 13) for short circuit and interruption. In case of a malfunction
acoustic and visual alarms will be induced. Visually, the kind of malfunction will be coded on the display, alternating with the
current operation data, pending the user's confirmation (ill. 1 and 2).
The current process stops, heating as well as running time functions. After confirming the displayed malfunction with key
③, the acoustic alarm is switched off and the visual indication (ill. 1) of the kind of malfunction disappears. The malfunc-
tion, marked in yellow and with a "caution" symbol, as well as the code number remain shown in the display of on-going
process data (see ill. 3). The blue symbol indicates the necessity of consulting the operating instructions. Error codes 001,
002 and 003 must be reset by pressing key ④ (shortly), error codes 004 and 005 must be reset by switching off the
Water Bath's main switch. Only after a technical analysis of the malfunction should the terminated process be restarted.
