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
Pt100
;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.
;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.
;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.
