Cryo-Compact Circulators

Operating manual

1. Intended use

JULABO Cryo-Compact Circulators have been designed for temperature application to 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

 The Cryo-Compact 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 DIALOGDISPLAY. Three menu keys facilitate adjusting setpoints, warning and safety functions and menu functions.

TCF

ATC

RS232 RS485

Pt100

SMART

PUMP

 The integrated programmer allows storing and running temperature and time-

dependent processes.

 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). 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 applications..

Temperature application to external, open systems

S = Suction pump connection D = Pressure pump connection K = Float H = Height adjustment

Tubing see page 21

The Cryo-Compact Circulator is equipped with both a pressure and suction pump for external temperature application in open systems.

Differing flow rates of the pressure and suction pumps should be compensated. To maintain a constant liquid level, the JULABO „D+S“ Level Adapter is recommended for the external bath tank. The flow rate of the pressure pump will be then regulated by a built-in float device. The liquid level may be changed by a height adjustment on the „D+S“ Level Adapter.

Accessory: „D+S“ Level Adapter Order No. 8 970 410

Important:

 The liquid level should be equal in the internal and external baths

(absolute height).

 If you take out samples (for example Erlenmeyer flasks) from the

external bath, turn the Cryo-Compact Circulator off with the Start/Stop key.

5.3. Tubing

Warning: Tubing:

At high working temperatures, the tubing used for temperature control and for the cooling water supply represents a danger source.

Recommended tubing:

A damaged tubing line may allow a large amount of hot bath fluid to be pumped out within a short time.

This may result in:

 Burning of skin  Breathing difficulties due to hot atmosphere

Safety instructions

 Use suitable connecting tubing.  Make sure that the tubing is securely attached.  Avoid sharp bends in the tubing and maintain a sufficient distance from

surrounding walls.

 Regularly check the tubing for material defects (e.g., for cracks), at least once a

year.

 Preventive maintenance: replace the tubing from time to time.

5.4. Bath fluids

Caution:

Carefully read the material 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 scale in the bath

 Ferrous water can cause corrosion, even on stainless steel.  Chlorinated water can cause pitting corrosion.  Distilled water and deionized water are unsuitable. Their special properties

cause corrosion in the bath, even on stainless steel.

Recommended bath fluids:

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

See website for list of recommended bath fluids.

Contact: see page 6

Caution:

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

Please contact JULABO before using other than recommended bath liquids.

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

(much higher than 70 mm2 x s-1 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!

ATTENTION: The maximum permissible viscosity is 70 mm

6. Operating procedures

6.1. Power connection

Caution:

 Only connect the unit to a power socket with an earthing contact (PE – protective

6.2. Filling

earth)!

 The power supply plug serves as a safe disconnecting device from the line and

must always be easily accessible.

 Never operate the unit with a damaged mains power cable.  Regularly check the mains power cables for damage.

 We disclaim all liability for damage caused by incorrect line voltages!

Make sure that the line voltage and frequency match the supply voltage specified on the type plate.

Cryo-Compact Circulators

Notice:

Pay attention to the thermal expansion of bath oil during heating to avoid overflowing of the liquid.

Guideline: A volume change of 12 % per 100 °C temperature variation is to be considered.

Take care that no liquid enters the interior of the Cryo-Compact Circulator .

 Connect the tubing from the external system to the pump

connectors and check for leaks

 Check to make sure that the drain tap (7) is closed.

Recommendation: For filling, use for example an measuring jug with nuzzle.

 Recommended maximum filling level with water as bath fluid:

30 mm below the tank rim

 Recommended maximum filling level with bath oils:

40 mm below the tank rim

 Turn the mains switch (1) on

(Switching on - see page 24)

 Switch on unit by pressing the start/stop key  Tempering fluid is pumped into the externally connected system.

Refill fluid up to recommended filling level.

 The Cryo-Compact Circulator is ready for operation.

Operating procedures

Important:

 When using a bath fluid, the change in volume in case of change in

temperature has to be respected. Fill in a little amount of bath fluid only so that the low level alarm is not triggered.

 Low level alarm is triggered at the following liquid level:

CF31 75 to 80 mm below the tank rim CF41 80 to 85 mm below the tank rim

 When reaching the working temperature, check the liquid level. If the

cooling coil is not completely covered with bath fluid, refill it.

The E-Prog input can only be used either under menu item >Setpoint< or under menu item >Variable< (page 34).

Autostart

Possible parameters:

on - AUTOSTART on off - AUTOSTART off (Factory setting)

Note:

The temperature system has been configured and supplied by JULABO according to N.A.M.U.R. recommendations. This means for the start mode, that the unit must enter a safe operating state after a power failure (non-automatic start mode). This safe operating state is indicated by „ OFF „, resp. R OFF on the VFD-COMFORT-DISPLAY. A complete shutdown of the main functional elements such as heater and circulating pump is effected simultaneously.

The values set on the Cryo-Compact Circulator remain stored, and the unit is returned to operation by pressing the start/stop key (in manual control mode). In remote control mode, the values need to be resent by the PC via the interface.

Should such a safety standard not be required, the AUTOSTART function (automatic start mode) may be activated, thus allowing the start of the instrument directly by pressing the mains power switch or using a timer.

 The AUTOSTART function can only be used, if setpoint setting is carried

out via >keyboard< or >eprog< or >ext. Pt100<.

Warning:

For supervised or unsupervised operation with the AUTOSTART function, avoid any hazardous situation to persons or property. The instrument does no longer conform to N.A.M.U.R. recommendations.

The safety and warning functions of the instrument should always be used to their fullest capacity.

 Programming of variables for the parameters > serial < or > eprog < is only

accepted, if the unit is in Start mode.

Possible parameters: control – The internal control electronics of the Cryo-Compact Circulator

controls the heater and cooling machine. Self-tuning is possible.

serial – The heater or cooling machine receives the control signal via the serial

interface. Self-tuning is not possible.

eprog - The heater or cooling machine receives the control signal via the E-

Prog input. Self-tuning is not possible. (option). Important:

Set the parameter >EPROG< and the input variables also in the menu >Inputs/Outputs< (see page 52).

Note: The E-Prog input can only be used either under menu item >Setpoint< (page 32) or under menu item >Variable< (see above).

Warning:

The working temperature range of the Cryo-Compact Circulator is determined during configuration. If set to >Control<, this range cannot be exceeded. If set to > serial < and > eprog <, heat or cold is applied to the bath without control. The permissible maximum temperature can be exceeded. The user has to take adequate precautions for temperature control. Materials, such as gaskets or insulations for example, may be damaged or destroyed, if the permissible maximum temperature is exceeded.

The safety and warning functions of the instrument should always be used to their fullest capacity. (See page 27)

8.4. Integrated programmer

The integrated programmer allows any desired temperature program

sequences to be realized. Such a temperature sequence is called profile. A profile consists of individual sections defined by duration (t:) and target temperature. Target temperature is the setpoint (T:), that is achieved at the end of a section. The programmer uses time and temperature difference values within a section to calculate a temperature ramp.

2. Connect an external contact ‚AK‘ (e.g. for emergency switch-off) or an alarm contact of the superordinated system.

In case the connection between Pin 2 and Pin 3 is interrupted by opening the contact ‚AK‘, a complete shutdown of the circulating pump and heater is effected, and the unit enters the condition „E OFF“. As long as the contact remains open, line 4 of the LCD DIALOGDISPLAY flashes and displays the message „STAND-BY“.

If the contact is reclosed, the instrument returns to the standby state and „ E OFF „ is displayed. Press

to start.

 Additional tips for using the STANDBY input:

The standby function can be used in conjunction with the AUTOSTART feature (see page 33).

1. If the Autostart function is NOT turned ON, the standby input is used as described above.

2. If the Autostart function is enabled, the instrument will revert back to the original method of entering the setpoint (i.e. keypad, RS232, Analog input, etc.).

 Entering the setpoint with the keypad.

As described above, a bipolar shut-down is accompanied by the „STAND-BY“ display and the OFF state. The programmable controller starts again when the contact is reclosed. The temperature of the bath fluid changed during the STAND-BY state.

 Entering the setpoint with the programmer

display „STAND-BY“ appears. The setpoint value and the time are both held at the current value. The temperature of the bath fluid will be held constant at this temperature. The programmer continues once the contact is reclosed.

Type:

A >1-point<, >2-point < or >3-point < calibration can be carried out. First geometrically define the location for calibration (measuring point T

), then determine the temperature values of of the calibration

points. The calibration type also determines the number of pairs of values indicated on the LCD DIALOG-DISPLAY.

TmpValue: 1 or 2 or 3

Defined temperature value of the calibration point. This value is automatically stored with >CalValue< and can be indicated for control purposes.

CalValue: 1 or 2 or 3

The „Calibration value“ is determined with a temperature measuring device and stored under menu item >CalValue<.

Principle: For ATC calibration, in steady state the bath temperature at the location of the temperature sensor (T

) is determined at the respective adjusted

working temperature. This value is then set on the Cryo-Compact Circulator in the menu >ATCalibration< under menu item >Calvalue X<. This can be a 1-point, 2-point or 3-point calibration.

2. In the menu >Configuration< set the menu item >Setpoint< to >RS232< or >RS485<. (>Configuration< see page 32)

3. Connect both units with an interface cable..

Like all parameters which can be entered through the keypad, interface

parameters are stored in memory even after the Cryo-Compact Circulator is turned off.

11.2. Communication with a PC or a superordinated data system



If the Cryo-Compact Circulator is put into remote control mode via the configuration level, the VFD COMFORT-DISPLAY will read „R -OFF-„ = REMOTE STOP. The Cryo-Compact Circulator is now operated via the computer. In general, the computer (master) sends commands to the Cryo-Compact Circulator (slave). The Cryo-Compact Circulator sends data (including error messages) only when the computer sends a query.

In remote control mode: After a power interruption the order to start and all values which have to be adjusted must be resent from the personal computer via the interface. AUTOSTART is not possible.

A transfer sequence consists of:

 address (RS485 interface only)  command  space (; Hex: 20)

 parameter (the character separating decimals in a group is the period)  end of file (; Hex: 0D)

 The response (data string) after an in command is always followed by a

line feed (LF, Hex: 0A).



Important times for a command transmission:

To ensure a safe data transfer, the time gap between two commands should be at least 250 ms. The Cryo-Compact Circulator automatically responds to an in command with a data string followed by a LF (Line Feed). The next command should only be sent after 10 ms.

Cryo-Compact Circulators



The commands are divided into in or out commands.

in commands: asking for parameters to be displayed out commands: setting parameters

The out commands are valid only in remote control mode. Examples:

When the RS485 interface is used, the three-digit instrument address stands in front of each command. (example: address Ad32 = A032)
