1. Intended use
JULABO circulators have been designed to control the temperature of specific fluids in a bath tank.
luxury foods and tobacco, or pharmaceutical and medical products.
Direct temperature control means unprotected contact of the object with the bath
1.1. Description
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 and LCD DIALOG-DISPLAY. Three
menu keys facilitate adjusting setpoints, warning and safety functions and menu
functions.
The integrated programmer allows storing and running temperature and time-
dependent processes.
SL
The control electronics including “ICC - Intelligent Cascade Control“ automatically
adapts the heat supplied to the thermal requirements of the bath.
The TCF - Temperature Control Features allow the user to have access to all
important temperature control parameters. This means: Full control on the control
mode and the chance to manually adjust or adapt control to the specific application.
Absolute Temperature Calibration (ATC3) provides 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, 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 LCD DIALOG-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
shut-down 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

5. Preparations
5.1. Installation
• Place the unit on an even surface on a pad made of non-flammable
material.
• Cooling machine, pump motor and electronics produce intrinsic heat that
is dissipated via the venting openings! Never cover these openings!
• Keep at least 20 cm of open space on the front and rear venting grids.
• The place of installation should be large enough and provide sufficient
air ventilation to ensure the room does not warm up excessively because
of the heat the instrument rejects to the environment. (Max. permissible
ambient temperature: 40 °C).
For a fault (leakage) in the refrigeration system, the standard EN 378
prescribes a certain room space to be available for each kg of
refrigerant.
The refrigerant quantity is specified on the type plate.
> > For 0.25 kg of refrigerant R134a, a room space of 1 m

is required.
• Do not set up the unit in the immediate vicinity of heat sources and do
not expose to sun light
• Before operating the unit after transport,
it up. This will allow any oil that has accumulated laterally during
transport to flow back down thus ensuring maximum cooling
performance of the compressor.
The circulating pump transports the
bath fluid to the temperature chamber
(4) at the bottom (3). The overflow on
top of the chamber ensures a constant
fluid level during operation.
