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
TCF
A
TC3
RS232
Pt100
;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 VFD COMFORT-DISPLAY. Three menu keys facilitate adjusting
setpoints, warning and safety functions and menu functions.
;Temperature- and time-dependent processes can be stored and executed using the
integrated programmer.
;The control electronics including “ICC - Intelligent Cascade Control” automatically
adjust the heat supply to the thermal requirements of the bath.
;The TCF - Temperature Control Features give the user access to all important
temperature control parameters. This means full control of the control behavior at all
times and the ability to manually adjust or adapt the controls to the specific
application.
;Absolute Temperature Calibration (ATC3) provides high temperature stability at all
points 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 entire temperature range.
;Electrical connections:
The serial interface, switchable from RS232 to RS485, allows modern process
technology without additional interface.
Connection for Pt100 external sensor for external temperature measurement and
control.
Alarm output for external alarm message or control of JULABO refrigerating baths
or solenoid valve (cooling water).
The electronic module (option) provides 3 further analog connections (alarm input,
standby input, recorder output, programmer input).
;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 VFD COMFORT-DISPLAY.
;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
shutdown of the main functional elements.
;Intelligent pump system: The pump capacity (electronically adjustable via the motor
speed) enables to adapt to varying conditions for internal and external temperature
applications.

Information about the used refrigerants
The Regulation (EU) No. 517/2014 on fluorinated greenhouse gases applies to all systems which
contain fluorinated refrigerants and replaces (EC) 842/2006.
The aim of the Regulation is to protect the environment by reducing emissions of fluorinated
greenhouse gases.
Among other things it regulates the emission limits, use and recovery of these substances. It also
contains requirements for operators of systems which require/contain these substances to function.
Under Regulation 517/2014, the operator of a system of this nature has the following duties:
xThe operator must ensure that the equipment is checked at regular intervals for leaks.
xThese intervals depend on the CO2equivalent of the system. This is calculated from the
refrigerant fill volume and type of refrigerant. The CO2equivalent of your system is shown on
the model plate.
xThe operator undertakes to have maintenance, repair, service, recovery and recycling work
carried out by certified personnel who have been authorized by JULABO.
xAll such work must be documented. The operator must keep records and archive them for at
least five years. The records must be submitted to the relevant authority on request.
Refer to the text of the Regulation for further information.
