Refrigerating/Heating and Heat Only Circulating Baths with the Programmable Controller are designed for use as stand-alone baths or to provide precise temperature control of fluids for open or closed loop circulation to external equipment. Refrigeration is normally required for operation at temperatures below 40¡C.
All Circulating Bath models feature a reservoir, which may be used for immersing samples while the unit is connected to an external device. Circulating Bath models are equipped with a 6 or 10 liter reservoir. All wetted parts are corrosion-resistant 300 series stainless steel.
Warning: These units are equipped with over-temperature protection (Safety Set). A low-liquid level or failure to set the Safety Set and properly immerse the heater may result in heater burnout and triac failure. While operating, do not allow the heater to contact any potentially flammable materials, such as plastic trays or the sides of plastic tanks, as a fire hazard may result.

? !!! ./%0,-&'(%!5,6#!
The CirculatorÕs variable speed duplex (pressure/suction) pump may be used for tempering of samples in the reservoir or for circulation in open or closed loop systems.
Pump speed is selected via the Main Menu (see Section 4.11.7 Ð Selecting the Pump Speed). The Low setting is adequate for most applications and provides quieter pumping. High is recommended where temperature varies frequently and there is a need for fast recovery or when pumping to multiple external units.

Line Frequency = 60Hz |
LineFrequency = 50Hz |
Variable up to: |
30 LPM / 5.0 PSI |
22 LPM / 3.4 PSI |
This data is based on the following criteria:
1.Maximum pump outlet flow rate is measured in liters per minute (LPM) with no restriction on the pump outlet.
2.Maximum pump outlet pressure is measured in pounds per square inch (PSI) at no flow.
3.Water was used as the circulation fluid. Water has a viscosity of one centistoke. High viscosity or low-density fluids will change these figures.

? ! 5,6#! +-$'!&+;!",'-$'!.(++$0'/(+)!!
The pump inlet and outlet ports are female ¼ inch NPT connections that permit use of barbed tubing adapters or hard plumbing fittings. ½ inch (13mm) ID tubing may also be slid over these connections and held in place with a hose clamp. If the pump inlet and outlet are not used for external circulation, they should be connected using the tubing provided with the unit in order to optimize fluid mixing within the reservoir.
Picture 1: Inlet to outlet connection. When bath is not circulating with an external device, the tubing provided with the unit should be used as shown above.
The nylon barbed tubing adapter fittings supplied with the unit are intended for temperature control from -40¡to 93¡C. For controlling temperature above 93¡C, brass, stainless steel, or Teflon¨ fittings are recommended. ¼ inch NPT to M16 stainless steel male adapter fittings are provided with all 50Hz models.
IT IS THE USER’S RESPONSIBILITY TO ENSURE THAT THE TUBING AND FITTINGS CONNECTED TO THE CIRCULATOR ARE COMPATIBLE WITH THE BATH FLUID AND TEMPERATURE RANGE BEING USED.
NOTE: The use of quick-connect fittings will restrict flow rate. Therefore a high or maximum pump speed should be used.

? !! .-()$;!K((#!./%0,-&'/(+!
Connect the pump inlet and outlet to the external apparatus (See Picture 2 below). To maintain adequate flow, avoid restrictions in the tubing. When connecting the Circulator to more than two closed loops, the use of a manifold made of "Y" adapters to divide the fluid into multiple banks is recommended. After setting up multiple closed loops, check for adequate flow at the return manifold of each loop and check that the bath fluid is at an adequate level. A booster pump may be added to closed loops without damaging the CirculatorÕs bath pump.

The temperature control stability of a closed loop system is better at the external apparatus than in the Circulator reservoir (provided the control point of the apparatus represents a constant load and is well insulated). For example, if you circulate fluid through a viscometer at 50¡C, the temperature variation observed in the Circulator reservoir may be ±0.2¡C while the temperature variation in the viscometer may be only ±0.1¡C.
Although temperature stability is generally better at the external apparatus control point, depending on the length of tubing used and the efficiency of the insulation, the actual temperature reading at the external apparatus may be slightly different than the temperature reading at the Circulator reservoir.
?L!! "#$+!K((#!./%0,-&'/(+!
The duplex pump permits circulation to and from an external open bath. To prevent siphoning when the Circulating Bath is turned off, position both baths so that the two fluid levels are at the same elevation.
Connect the pump inlet and outlet to the external bath using tubing of the same diameter and length. The same size fittings should also be used on both the inlet (suction) and outlet (pressure). This helps ensure a balanced flow. A restricting valve or pinch clip should be installed in the pressure (outlet) tubing and adjusted to match the return suction (inlet) flow rate. Cut the external end of the suction tube into a ÒVÓ shape so that the tube will not seal itself against the wall of the external tank. Both the pressure and suction tubing should be securely fastened to the external tank to prevent movement during use.
When using flexible tubing, the suction tubing must have a wall thickness that will not collapse under vacuum, particularly when going around bends.
5
Circulating Bath Height Regulation Ñ Position the ends of the pressure and suction tubes at the desired maximum fluid level in the external bath and fill the bath to that level. Fill the Circulating bath to a height one inch (25mm) below the top of the reservoir. Start the pump and adjust the restricting valve/pinch clip on the pressure tubing until the liquid height in both baths remains constant. Add fluid to the baths as needed to compensate for the fluid in the inlet and outlet lines.
?M! N/--/+1!'3$!:$)$%O(/%!!
The maximum fill level for the Circulating bath is one inch (25mm) below the top of the reservoir. A liquid level that fully covers the heater coil, pump, over-temperature sensor, and at least one inch (25mm) of the temperature sensor must be maintained. For optimum cooling efficiency, the bath fluid level in Refrigerating/Heating Circulators should be kept above the cooling coils at all times.
Upon start-up, it may be necessary to add fluid to compensate for the fluid required for external circulation. If the proper fluid
level is not maintained, the heater coil may become exposed and possibly damaged.

?P! :$)$%O(/%!5,%1$!
When operating at low temperatures, atmospheric moisture tends to migrate into the reservoir and condense. The 1/8 inch OD Reservoir Purge tube allows you to inject inert gas into the Circulating Bath to prevent the build-up of condensation.

Locate the Circulator on a level surface, free from drafts and out of direct sunlight. Do not place it where corrosive fumes, excessive moisture, high room temperatures, or excessive dust are present.
Refrigerating/Heating Circulators must be a minimum of four inches (102mm) away from walls or vertical surfaces so air flow around the unit is not restricted.
To help prevent voltage drops, position the Circulator as close as possible to the power distribution panel and a properly grounded outlet. The use of an extension cord is not recommended.
Warning: These units are equipped with over-temperature protection (Safety Set). A low liquid level or failure to set the Safety Set and properly immerse the heater may result in heater burnout and triac failure. While operating, do not allow the heater to contact any potentially flammable materials, such as plastic racks or the sides of plastic tanks, as a fire hazard may result.

Fill the reservoir with the appropriate bath fluid. The liquid level should be sufficient to cover the heating coils, pump, over-temperature sensor, and at least one inch (25mm) of the temperature sensor.
After filling the reservoir with fluid, you must set the Safety Set and the Limit High value as well as your desired control set point temperature.

The Programmable Controller is designed to accommodate an optional remote temperature probe. The probe (order p/n DVP-94Y) attaches with an adapter (order p/n TC-54Y), to the 9-pin male D-connector on the rear panel of the Controller.
The Controller will automatically sense the presence of the external probe when main power (rear panel circuit breaker/power switch) is turned On. To control temperature using the external probe, ÒExternalÓ must be selected via the ControllerÕs software. You must also set a Maximum Setpoint Differential value. See Section 4.11 Ð Setting Operational Parameters and Functions - Selecting the Temperature Probe.
To attain better temperature uniformity when using the external temperature probe in a jacketed or air-filled vessel, stirring the external fluid with pumps or mixing air with fans is recommended. Expect only ±1.0¡C stability with air or any medium that does not conduct heat well. Insulate and cover the entire set-up to remove temperature gradients; the Controller cannot compensate for external chamber or component temperature gradients.

Programmable Controllers incorporate an RS232 interface to provide remote data-logging and control capability. The 9-pin female RS232 connector is located on the rear panel of the Controller.
The RS232 interface should be connected to a serial communication port on a remote PC using an appropriate cable (RSS-E1) supplied with the bath. Information on the RS232 command and communication protocol can be found in Section 8.2 Ð RS232.

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. See Section 6 Ð Troubleshooting for information on recalling this display.
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 ÒStandbyÓ 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 (see Section 4.6 below).

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.

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:
The pump will begin operating; the display will show the current bath temperature and the set point temperature (Setpoint). If an external probe is connected, both the internal and external bath temperatures will be displayed. The temperature probe selected to control bath temperature (internal or external) will be displayed in larger numerals.

NOTE: If the external temperature probe is selected to control bath temperature, but the temperature difference between the set point temperature and the internal bath temperature exceeds the Maximum Setpoint Differential setting, the heating/cooling rate will be controlled using the internal bath temperature until the set point/internal bath temperature difference is within the Maximum Setpoint Differential value. The word Internal will be highlighted on the display to indicate that the internal sensor is controlling bath temperature. See Selecting the Temperature Probe in Section 4.11 Ð Setting Operational Parameters and Functions for more information.

This enables the user to lock all controls on the controller. While the feature is activated, the unit will remain running at the current settings.
To activate the local lockout feature, press and hold the Select/Set Knob for 10 seconds. Once locked, ÒLocalLockÓ will appear in the upper left corner of the display. The controller menus may still be viewed when Local Lockout is active, but no changes may be made.
Press and hold the Select/Set Knob again for 10 seconds to unlock the controls. Once unlocked, ÒLocalLockÓ will disappear and the menu settings can once again be modified.

Press and release the Select/Set Knob. The ÒwholeÓ numbers in the set point temperature will be highlighted. Rotate the Select/Set Knob clockwise to increase the displayed value; rotate the knob counter-clockwise to decrease the displayed value.
Press the Select/Set Knob to accept the new value. The decimal value in the set point temperature digits will be highlighted. Rotate the Select/Set Knob clockwise to increase the displayed value; rotate the knob counter-clockwise to decrease the displayed value. Press the Select /Set Knob to accept the new value.
NOTE: Increasing/decreasing the decimal value past Ò0Ó will cause a corresponding change in the ÒwholeÓ number value. For example, if the current set point value is 24.8 and the desired value is 25.2, it is not necessary to change the 24 to a 25; increasing the decimal value from .8 to .2 will automatically increase the 24 to 25.
The Controller will not allow you to enter a set point value above the Limit High setting or below the Limit Low setting. Should you attempt to do so, the set point value will stop increasing/decreasing when the Limit value is reached and a Warning message will appear on the display. You must either change the set point or change the Limit value. See Section 4.11 Ð Setting Operational Parameters and Functions Ð Setting High/Low Temperature Limits and Alarms.
NOTE: Programmable Controllers can also be operated using a programmed Time/Temperature profile. See Entering/Modifying a Temperature Program and Running a Temperature Program in Section 4.11 Ð Setting Operational Parameters and Functions for more information.
