Operating manual

1.Intended use

JULABO circulators have been designed to control the temperature of 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 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 MULTI-DISPLAY (LED). Three menu keys facilitate adjusting setpoints, warning and safety functions and menu functions.

The PID temperature control adapts the heat supplied to the thermal requirements of the bath.

PID2	 Absolute Temperature Calibration (ATC3) provides a high temperature
PID2	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
ATC3	in the bath over the full temperature range.
ATC3	 Electrical connections:
	The serial interface RS232 allows modern process technology without
RS232	additional interface.
RS232	Alarm output for external alarm message or control of JULABO refrigerating
	baths or solenoid valve (cooling water).
	 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 MULTI-DISPLAY (LED).
	 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.
	 The pump capacity (electronically adjustable via the motor speed) enables to
	adapt to varying conditions for internal and external temperature
SMART	applications.
PUMP	 The circulator conforms to the relevant requirements specified by European
	guidelines.

Information about the used refrigerants

The Regulation (EU) No. 517/2014 on fluorinated greenhouse gases applies to all systems which contain fluorinated refrigerants and replaces (EC) 842/2006.

The aim of the Regulation is to protect the environment by reducing emissions of fluorinated greenhouse gases.

Among other things it regulates the emission limits, use and recovery of these substances. It also contains requirements for operators of systems which require / contain these substances to function.

Under Regulation 517/2014, the operator of a system of this nature has the following duties:

•The operator must ensure that the equipment is checked at regular intervals for leaks.

•These intervals depend on the CO2 equivalent of the system. This is calculated from the refrigerant fill volume and type of refrigerant. The CO2 equivalent of your system is shown on the model plate.

•The operator undertakes to have maintenance, repair, service, recovery and recycling work carried out by certified personnel who have been authorized by JULABO.

•All such work must be documented. The operator must keep records and archive them for at least five years. The records must be submitted to the relevant authority on request.

Refer to the text of the Regulation for further information.
