3.2 Heater/Stirrer Set-Up and Programming – continued
3.2h Power
An IEC power cord is provided with the Circulator. This power cord should be plugged into the IEC receptacle on the
rear of the Controller and then plugged into a properly grounded outlet. Make sure that the power outlet is the same
voltage and frequency indicated on the identification label on the back of the Controller.
The use of an extension cord is not recommended. However, if one is necessary, it must be properly grounded and
capable of handling the total wattage of the unit. The extension cord must not cause more than a 10% drop in voltage
to the Circulator.
Once the unit has been connected to an appropriate electrical outlet, place the Circuit Breaker/Power Switch on the
rear of the Controller in the ON position. The unit will run through a self-test.
The first time power is applied to the Controller, the following display will appear. This display allows you to select
the language that will be used for all subsequent displays. The instructions for selecting a language will be briefly
displayed in each available language.
NOTE: The language selection display only appears the first time the Controller is powered up.
When the language selection display appears, rotate the Select/Set Knob until the desired language is highlighted
and then press the Select/Set Knob. The Controller will continue with the start-up sequence and then display
“Standby” on the LCD.
DO NOT place the Power Switch on the front of the Controller ON until the Safety Set has been adjusted to the
desired temperature.
3.2i Setting the Safety Set Point
The Safety Set feature automatically disconnects Controller power to the heater and pump in the event that the
reservoir liquid level drops too low or the sensed temperature exceeds the Safety Set temperature. The Safety Set
is user-adjustable between approximately 40° and 210°C. It should be set at least 5°C higher than the desired bath
temperature.
Use a flat blade screwdriver to rotate the Safety Set Indicator Knob to the desired temperature.
Do not force the knob beyond the stops at either end of the temperature value range.
If the Safety Set temperature is exceeded during normal operation, a fault message will flash on
the display and power to the heater and pump will be disrupted. To reset the fault, correct the problem (low liquid
level, incorrect Safety Set temperature, etc.), press the Safety Set Reset Button, and then the ESC Button. Normal
operation will resume.
3.2j Power On
Once the Safety Set temperature has been set, turn power to the Controller ON by pressing the Power Switch on the
front of the Controller. The following message will appear briefly on the display:
