Checking the Over-Temperature Safety System
Your Circulator incorporates over-temperature protection according to IEC 61010. For optimum safety,
this system should be checked for proper operation at least every six months. This check must be
performed with the unit running.
1. Press
, enter a temperature set point of approximately 50°C, and then allow the bath to stabilize
at that temperature. The amount of time this will take will depend on the size of the bath and the
difference between the initial bath temperature and the Safety Set temperature.
2. Using a small flat blade head screwdriver, slowly rotate the Safety Thermostat located on the rear of
the Temperature Controller counter-clockwise until you hear a soft click; the OVERTEMP or LOW
FLUID alarm message will appear and the alarm will sound. The heater should also turn OFF.
3. Press
to turn the Circulator OFF.
4. Rotate the Safety Thermostat clockwise a few degrees and then reset the Safety Set by inserting the
blade of the screwdriver or the end of a paperclip into the access slot and pressing until you hear the
Safety Set reset (an audible click).
5. Press
to turn the Circulator back ON and reset the Safety Set temperature to the desired
temperature value (see
Controller Setup, Safety Set Temperature
).
