Operating manual
1. Intended use
JULABO circulators have been designed to control the temperature of specific fluids in a bath
tank.
JULABO circulators are not suitable for direct temperature control of foods, semi-
luxury foods and tobacco, or pharmaceutical and medical products. Direct
temperature control means unprotected contact of the object with the bath
medium (bath fluid).
1.1. Description
PID1
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.
2. Operator responsibility – Safety recommendations
The products of JULABO ensure safe operation when installed, operated, and maintained
according to common safety regulations. This section explains the potential dangers that may
arise when operating the circulator and also specifies the most important safety precautions to
preclude these dangers as far as possible.
