Displays and controls

For normal operation, only the power switch on the right-hand side of the operating panel
of the Barkey warming center III DTM is of interest. The temperature has been set at the
works, so that once the device has been switched on no further displays and controls are
necessary.
If the door is opened, the circulating air temperature regulation switches off automatically
and the operating display (green lamps) flashes. If a fault is present, this is indicated by
the fault display (red lamps) illuminating or flashing.

The TSI keyswitch on the right-hand side of the operating panel is also required for car-
rying out the TSI. The TSI keyswitch actuates special testing conditions in order to enable
checking of the electronic and mechanical overtemperature protection function.

WARNING
The temperature display flashes if the electronic or mechanical overtemperature
protection test function is activated via the keyswitch. The heating device may not
be used for heating temperature-regulated goods in this condition.

overtemperature protection.
