Barkey warming center III DTM
►
If the Barkey warming center III DTM heating chamber has not already been warmed
up to 42°C, operate the device as described in the instruction manual. Wait until the
display shows a temperature of 42°C and the measured temperature in the heating
chamber is stable. If the heating chamber is cold, this will take around 60 minutes. If
the device is warm, the waiting period will be shorter.
►
Switch the Barkey warming center III DTM off.
►
Turn the keyswitch to the "TSI-e" position.
►
Switch the Barkey warming center III DTM on.
The heater is permanently in operation at this "TSI-e" setting, and the temperature in the
heating cabinet increases. The temperature display will flash to show that the TSI test
function is activated.
As soon as the electronic overtemperature protection triggers, the fault display flashes
and an acoustic signal sounds for around six seconds.
►
Read the value of the temperature display when the electronic overtemperature pro-
tection is triggered and enter this in the inspection log.
WARNING
If the value determined lies outside the prescribed tolerance of 46°C ± 1°C, the
Barkey warming center III DTM needs to be readjusted (see chapter 6.3). The TSI
must be repeated afterwards.
►
Switch the Barkey warming center III DTM off.
►
Turn the keyswitch to the "TSI-m" position.
►
Switch the Barkey warming center III DTM on.
In "TSI-m" check status, the heater is permanently triggered and the electronic overtem-
perature protection is bypassed. The temperature in the heating cabinet increases, and
activation of the TSI check function is indicated by the temperature display blinking.
As soon as the mechanical overtemperature protection triggers, the fault display illumi-
nates permanently and an acoustic signal sounds for around six seconds.
►
Read the value of the temperature display at the time the mechanical overtempera-
ture protection is triggered.
►
Enter the trigger value in the inspection log.
WARNING
If the value determined lies outside the prescribed tolerance of 51°C ± 3°C, the
mechanical overtemperature protection needs to be replaced (see
chapter 7.5). The TSI must be repeated afterwards.
