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, semiluxury 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

 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.

ICC

TCF

ATC

RS232 RS485

Pt100

 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.

SMART

PUMP

 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 applications.

Safety notes for the user

Caution:

The temperature controlling i.e. of fluids in a reactor constitutes normal circulator practice.

We do not know which substances are contained within these vessels. Many substances are:

 inflammable, easily ignited or explosive  hazardous to health  environmentally unsafe

i.e.: dangerous

The user alone is responsible for the handling of these substances!

The following questions shall help to recognize possible dangers and to reduce the risks to a minimum.

 Are all tubes and electrical cables connected and installed?

Note: sharp edges, hot surfaces in operation, moving machine parts, etc.

 Do dangerous steams or gases arise when heating?

Is an exhaust needed when working?

 What to do when a dangerous substance was spilled on or in the unit?

Before starting to work, obtain information concerning the substance and determine the method of decontamination.



Notice: Check the safety installations at least twice a year!

 Excess temperature protection according to IEC 61010-2-010.

With a screwdriver turn back the adjustable excess temperature protection until the shut-down point (actual 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, wait about one hour after setting

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 bath cover (1) is mounted on the bath tank with 4 captive screws (2).

Required tool: SW3 hexagonal socket wrench with ball-shaped head

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.

The bath cover (5) provides 6 measuring places (6) that can be fitted with different Viton

Preparations

5.2. Bath fluids

Caution:

Carefully read the safety data sheet of the bath fluid used, particularly with regard to the fire point! If a bath fluid with a fire point of 65 °C is used, only supervised operation is possible.

Water: The quality of water depends on local conditions.  Due to the high concentration of lime, hard water is not suitable for temperature

control because it leads to calcification in the bath.

 Ferrous water can cause corrosion - even on stainless steel.  Chloric water can cause pitting corrosion.  Distilled and deionized water is unsuitable. Their special properties cause

corrosion in the bath, even in stainless steel.

Recommended bath fluids:

Bath fluid Temperature range soft/decalcified water 5 °C to 80 °C

mixture water/glycol, mixture 1:1

-20°C to 50°C

See website for list of recommended bath fluids.

ATTENTION: The maximum permissible viscosity is 70 mm

/s.

Caution:

Fire or other dangers when using bath fluids that are not recommended:

Use only non-acidic and non-corroding bath fluids.

JULABO assumes no liability for damage caused by the selection of an unsuitable bath liquid. Unsuitable bath fluids are fluids which, e.g.,

 are highly viscous

(much higher than recommended at the respective working temperature)

 have a low viscosity and have creep characteristics

 have corrosive characteristics or  tend to crack.

 No liability for use of other bath fluids!

5.3. Filling / draining

Notice:

 Pay attention to the thermal expansion of bath oil during heating to avoid

overflowing of the liquid.

 Do not drain the bath fluid while it is hot!

Recommendation: Temperature range 5 °C to 40 °C Check the temperature of the bath fluid prior to draining (by switching the unit on for a short moment, for example).

 Store and dispose the used bath fluid according to the laws for environmental

protection.

Filling

Take care that no liquid enters the interior of the circulator.

 The recommended filling level is marked with an

angle plate (M) inside the bath.

 When the filling level does not exceed the marker

(M) and providing a suitable bath fluid is used for the specified working temperature range of the unit, neither low liquid level alarm should be triggered nor overflowing of the bath fluid should be caused.

Draining:

 Turn off the unit and disconnect the mains cable

from the power source.

 Hold the venting grid, pull out and remove.

 Slide a short piece of tube onto the drain

connection and hold it into a container.

 Loosen the drain screw a few turns and drain the

unit completely.

 Tighten the drain tap.
