2. Safe Temperature Limit (STL) Range: > 50 – 360  C Factory setting: 360  C Set temperature: at least 10  C < STL “The safe temperature limit must always be set at least 25  C lower than the flash point of the media to be processed!” 2 Ika  -Werke RCT basic safety control/HCT basic safety control manual

3. Setting the STL Turn hot plate on with heating/stirring off Small flat-head screwdriver – Clockwise:  temp – Counterclockwise:  temp Very sensitive! – Expect large jumps in temp 3 Ika  -Werke RCT basic safety control/HCT basic safety control manual

4. Testing the STL If STL close to set temp, oil/water bath may never reach set temp – To heat water bath at 50  C, STL ≥ 80  Temp did not exceed STL after removal of probe If temperature probe disconnects while heating: – E6 = break in safety circuit 4 Ika  -Werke RCT basic safety control/HCT basic safety control manual
