Operating manual

1. Intended use

The High Temperatur e Cir c ulators HT60-M2 and HT60-M3 are to be employed especially for closed tempering circuits in the laboratory, the technical institution or the production, like e.g. for distillation plants, reaction vessels, autoclaves, injection moulding tools.

JULABO circulators are not suitable for direct t em per ature c ontrol of foods, semi-luxury foods and tobacco, or pharm ac eutical and medical products. Dir ec t t em per ature control means unprotected cont ac t of the object with the bath medium (bath fl uid) .

1.1. Description

The structure of the High Temperature Circulator HT60 is sub-div ided in three zones:

• The cold zone (on t op) wit h the electronics for controlling and monitoring, the tem per ature c ontrol and the pump motor.

• The cooling z one with the cooling coil, the fl oat f or the lev el indication, a temperature sensor for monitoring the temperatur e, t he c onnec tion for inert-gas, the connecti on for the expansion vessel as well as an overfl ow nozzle. At thi s place t he temper ature monitoring is independant from the other safety devices.

• The heati ng zone (down) with the heating element , t he pum p, t he temper ature sensors and the flow nozzl e

The C.U.-cooling unit can be installed firmly and fulfills two tasks.

• The temperature of the tempering liquid in the cooling zone is supervised. If it is necessary the cooling water is led through the integr ated cooling coil in order to reduce the temperature (without C.U.-cooling unit the cooling coil c an be connect ed dir ec tly to the cooling water).

• With a separate cooling circuit through the C.U.-cooling unit a rapid cooli ng of t he temper ing liquid becomes possible.

The M2 or M3 control electronics is connected to the HT60-circulator via a control cable.

• The local oper ation of the control electronics M2 / M3 is effected via a splash-water protected keypad. The Microprocessor technology allows to set three different temperatur e v alues, to store and to indicate them via the digi tal display LCD – the worki ng temperature and the values for t he excess and lower t em per ature warning functi ons.

• With the integrated programmer the instructions for setpoint and time for six different temperature pr ofiles can be stored and call ed in.

• Via an analog i nterface REG+E-PROG an analog programmer can be connec ted for the setpoint.

• At the same tim e this interface is provided with three analog outputs for the recorder. For the best resol ution

the output settings can be adjusted via the menu delete surfac e - should just be Menu. The remote control via the digital RS232/RS485 int erface according to NAMUR allows the m ost m oder n process technology without additional interface.

• The excess temper ature protection i s a safety equi pm ent which does not depend on t he control circle. Its safety value is shown and can be adjusted by the MULTI-DISPLAY (LED).

• The level of liquid is acquired in the cooling z one, indicated to the control el ectr onic s via the control cable. There they are made vi sibl e by an 8-grade level indication.

Operator responsibi lity – Safety instructions

2. Operator responsibility – Safety instructions

The products of JULABO ensure safe operation when installed, operated, and mai ntained according to common safety regulati ons. This section explains the pot ential dangers that m ay arise when operating the circulator and also specifies the m ost im por tant safety precautions to precl ude these dangers as far as possible.

The operator is responsible for the qualific ation of the personnel operating the units.

 The personnel operating the units should be regul arl y instruct ed about the dangers inv olv ed with their job

activiti es as well as m easures to avert these dangers.

 Make sure all persons tasked with operating, install ing, and maintaining the unit hav e r ead and under stand

the safety information and oper ating instructions.

 When using hazardous mat eri als or materials that could become hazardous, the circ ulator may be operated

only by persons who are absolutel y familiar with these materi als and the ci r c ulator. These persons must be fully aware of p ossible r isks.

If you have any questions concerning the operation of your unit or the information in this manual, please cont ac t us!

Safety instructions for the operator:

 Avoid strikes to t he housi ng, vibrations, damage to the operating-element panel ( k ey pad, display), and

contamination.

 Make sure the product is checked for proper condition regular ly (depending on the conditions of use).

Regularly check ( at least every 2 years) the proper condition of the mandatory, warning, pr ohibition and safety labels.

 Make sure that the mains power supply has l ow im pedanc e to avoid any negativ e eff ects on the instr um ents

being operated on the same mains.

 This unit is designed f or oper ation in a controlled electromagnetic environment. This means that transmitti ng

devices (e.g., cellular phones) should not be used in the immediate vicinity.

 Magnetic radiation may affect other devic es with c om ponents sen si tive to magnetic fields (e.g., monitors).

We recommend maintai ning a mi nim um distanc e of 1 m.

 Permissible am bient temperature: max. 40 °C, min. 5 °C.  Permissible r elative humidity: 50% (40 °C).  Do not store the unit in an aggressive atmosphere. Protect t he unit f r om cont ami nation.  Do not expose the unit to sunlight.

is not permitted!

Use

The bath can be filled with flammable materials. Fire hazard! There might be chemic al danger s dependi ng on the bath medium used. Observe all warnings f or the used m aterials (bath fluids) and t he r espect ive instructions (safety data sheets).

Insufficient ventilation may result in the formation of explosive mixtures. Only use the unit in well ventilated areas. Only use recommended m aterials (bath fluids). Only use non-acid and non c or r oding materials.

When using hazardous mat eri als or materials that could become hazardous, the operator must affix the enclosed safety labels (1 + 2) to the front of the unit so they are highly visible:

Particular care and at tention is necessary because of the wide operat ing range. There are thermal danger s: B ur n, scald, hot steam, hot parts and surfac es that can be touched.

Observe the instruc tions in the manuals for instruments of a different make that you connec t t o the cir c ulator, particularly the corresponding safety instr uc tions. Also observe the pi n assignment of plugs and technical specifications of the products.

Warning label W00: Colors: yellow, black Danger area. Attention! Observe instructions. (operating manual, safety data sheet)

Notice:

Danger of corrosion of heat exchanger due to unsuitable quality of cooling water.

• Due to its high content of lime, hard water i s not suitable for cooling and causes scale in the heat exchanger.

• Ferrous water or water containing ferrous particles will cause form ation of rust even in heat exchangers made of stainless steel.

• Chlorinated water will cause pit ting corrosion in heat exchangers m ade of stainless steel.

• Due to their corrosive characteri stics, distilled water and dei onized water are unsuitable

and will cause corrosion of the bath.

• Due to its corrosive characteri stics, sea water is not suitable.

• Due to its microbiological ( bacter ial) components, which settle in the heat exchanger,

untreated and unpurified river water and water from c ooling towers is unsuitable.

• Avoid particulate matt er in cooling water.
