E
Caution! Hazard of serious burns when running with hotplate over 50 °C.
Avoid contact with the hotplate, heating bath and liquid.
Caution!
When heating flammable substances, ensure that the nominal temperature
of the hotplate is at least 25 °C lower than the substance's flashpoint.
Ensure that the instrument is standing on a solid surface.
INTENDED USE
EKT Hei-Con and Hei-Con G are electronic temperature controllers for fluids. In the
laboratory they replace the conventional mercury contact thermometers and are intended
for application with magnetic stirrers and heating devices.
The MP-driven electronics assume the control and guarantee a high degree of linearity
and measuring accuracy. The integrated fuzzy control guarantees an optimum heating-up
speed without overshooting the temperature.
The control instrument can be positioned away from the heat and steam area as the
measuring sensor is not permanently fixed to it.
The temperature controller is protected in a variety of ways:
Short-circuit fuse sensor
Fracture protection sensor
Safety and control circuit in conformity with DIN 12878 Classes 1 and 2
Security shutdown when the set target temperature is surpassed by 25°C (MAX
temperature)
Security shutdown when the temperature sensor does not submerge in the liquid.
During operation, the measuring sensor and measuring line are continually checked for
disconnections and short circuit. If a fault occurs, the heating switches off and the fault is
indicated on the display.
