Operating manual
Description
The circulators SHC 2000 are designed for temperature application to specific fluids in a bath tank.
The circulators are operated via the splash-proof keypad. The implemented
microprocessor technology allows to set and to store the setpoint that can be indicated on the LED temperature display.
The PID temperature control adapts the heat supplied to the thermal requirements
of the bath.
Safety installations conforming to IEC 61010-2-010.
The excess temperature protection is a safety installation independent from the control circuit. The safety value is set using a tool (screwdriver). If the low level protection device is triggered, a complete shutdown of the heater and circulating pump is effected.
The circulator conforms to the relevant requirements specified by European
guidelines.
The circulators are not conceived for direct temperature application to food and luxury articles or pharmaceutical and medico-technical products. Direct temperature application means: Unprotected contact of the object with the bath medium (bath fluid).
Operator responsibility – Safety recommendations
