Operating manual
1. Intended use
JULABO circulators have been designed to control the temperature of specific fluids in a bath
tank.
The units feature pump connections for temperature control of external systems (loop circuit).
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
PID2
ATC3
RS232
PUMP
SMART
The circulators are operated via the splash-proof keypad. The implemented
microprocessor technology allows to set and to store different values that
can be indicated on the MULTI-DISPLAY (LED). Three menu keys facilitate
adjusting setpoints, warning and safety functions and menu functions.
The PID temperature control adapts the heat supplied to the thermal
requirements of the bath.
Absolute Temperature Calibration (ATC3) provides a high temperature
stability in the bath. With the 3-point calibration an offset is adjusted at three
temperatures to ensure an accurate temperature pattern at the selected spot
in the bath over the full temperature range.
Electrical connections:
The serial interface RS232 allows modern process technology without
additional interface.
Alarm output for external alarm message or control of JULABO refrigerating
baths or solenoid valve (cooling water).
The excess temperature protection conforming to IEC 61010-2-010 is a
safety installation independent from the control circuit. This protection can be
indicated and set on the MULTI-DISPLAY (LED).
The early warning system for low level signals that bath fluid needs to be
refilled before the low level protection conforming to IEC 61010-2-010
causes a complete shut-down of the main functional elements.
The pump capacity (electronically adjustable via the motor speed) enables to
adapt to varying conditions for internal and external temperature
applications.
The circulator conforms to the relevant requirements specified by European
guidelines.
