NOTE: To conserve power when not in use, the LCD’s backlighting will go out about 5 seconds after
“Standby” appears. The Power Key and PolyScience logo will remain lit to indicate that the Controller is
energized and ready to use.
Heat Only Circulators and Viscosity Baths
Attach the 6-ft / 1.8 m power cord to the IEC electrical connection on the Temperature Controller and then
plug the male connector into the Mains electrical outlet.
Place the Power Switch / Circuit Breaker on the Temperature Controller in the ON position. The LCD on
the Controller will light and “Standby” will appear on the display; the PolyScience logo and the Power Key
will also light.
NOTE: To conserve power when not in use, the LCD will go black about 5 seconds after “Standby”
appears. The Power Key and PolyScience logo will remain lit to indicate that the Controller is energized
and ready to use.
RS232 Serial Communication
CAUTION: Always turn electrical power to the Circulator OFF before making a connection to the
serial (DB9) port.
Your Circulator features RS232 serial communication for remote data logging and control capability. A 9-
pin female D-connector is provided on the rear of the Temperature Controller for this purpose.
The serial interface should be connected to a serial communication port on a remote PC using an
appropriate cable. Information on the RS232 command and communication protocol can be found in the
Technical Information section of this manual.
