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.

This means for the start mode, that t he unit must enter a safe operating state after a power failure (non-aut om atic start mode). This safe operati ng state is indicated by „OFF“ or „rOFF“, resp. on the MULTI-DISPLAY (LED). A complete shutdown of the main functional elements such as heater and circulation pump is effected simultaneously.

Should such a safety standard not be r equired, the AUTOSTART function (autom atic start mode) may be activated, thus allowing the start of the programmable c ontroller directly by pressing the mains power switch or using a tim er.

STAND-BY

STAND-BY input (32)

(for external em er genc y switc h-off)

Pin assignment: Pin Signal 1 not connected 2 5 V / DC 3 0 V Use shielded cables only.

Activate the stand-by input :

• Under menu item Stand-by, set the param eter to „yes“ (see page 43).

• Connect an external contact 'A K ' (e. g. f or em ergency switc h-off) or an alarm contact of t he superordinated system.

In case the connection between Pin 2 and Pin 3 is interrupted by opening the contact 'AK', a c om plete shutdown of the circulating pump and heater is effected, and the unit enters the condition "OFF". As long as the contact remains open, line 4 of the DIALOG-DISPLAY (LCD) flashes and displays the message „STAND-BY“.

If the contact is recl osed, the circulator returns to the stand-by status and „OFF“ is displayed.

Additional tips for using the STAND-BY input:

The Stand-by function c an be used i n c onjunc tion with the AUTOSTART feature (see page 42)

1. If the Autostart function is NOT turned ON, the Stand-by input should be used as described abov e.

2. If the Autostart funcion is enabled, the instrument will revert back to t he original method of entering the setpoint (i. e. key pad, RS232, Analog input, etc. ).

• Entering the setpoint with the keypad, for example . As described above, an bipolar BY” display and the OFF stat us. The progr ammable controller start s again when the contact is reclosed. The temperature of t he bath liquid changed during the STAND-BY st atus.

• Entering the setpoint with the programmer (see pages 47 and 49). The display „STAND-BY “ appears. T he setpoint value and the time are both held at the current value. The temperatur of the bath fluid will be held constant at this temper ature. The programmer conti nues once the contact is reclosed.

11.1. Setup for remote control

Select the „Confi gur ation“ submenu and select the option „Setpoint“ to define the int erfac e ( see page 42).

SERIAL

Like all parameter s which can be entered through the keypad, interface parameters are stored in memory even after the cir c ulator is turned off.

The interface par am eters are set by selecting the submenu „Int erface“ on the circulator Normally, this is a one-time-only adjustment. (Selecting and setting menu item s, see page 57.)

11.2. Communication with a PC or a superordinated data system

Suitable terminal programs for communicating with a PC are:

• MS-Windows - TERMINAL.EXE (included with MS-Windows).

• Easy Temp control soft ware – allows programming, v iewing, and rec or ding of temperature and time

dependent processes when using a si ngle JULABO instrument. Download free of charge from

www.julabo.com or J ulabo Order No. 8 901 102.

If the circulator is put into remote control mode via the configuration level, the display will r ead "r OFF" = REMOTE STOP.

The circulator is now operated via the computer. In general, the com puter (master) sends commands to the circulator (slave). The

circulator sends data (including error messages) only when the computer sends a query.



A transfer sequence consi sts of:

• address (RS485 interface only )

• command

• space (⇔ Hex: 20)

• parameter (the character separat ing decimals in a group is the period)

• end of file (↵; Hex: 0D)

The commands are divided into in or out commands. in commands: asking for parameters to be display ed

The out commands are valid only in remote contr ol m ode.

When the RS485 interface is used, the three-digit instrum ent addres s stand s i n front of each command. (example: address Ad32 = A032)

Examples:

Command to set the working temper ature T to 55.5 °C out_sp_00
