Página 8: Section I Safety
Section I Safety Warnings Make sure you read and understand all instructions and safety precautions listed in this manual before installing or operating your circulator. If you have any questions concerning the operation of your circulator or the information in this manual, contact our Sales Department (see After-sale Support). -
Página 33: Section Ii General Information
Section II General Information Description The Thermo Scientific ULT 80 and ULT 95 are self-contained refrigerated bath/circulators. The circulators consist of a circulating pump; heater; stain- less steel reservoir; microprocessor temperature controller; and a cascade configuration, air-cooled refrigeration system. The refrigeration control is independent of the main power switch so that the compressor may be turned off to allow fast warm-up. - Página 34 Cooling Capacity -80 -60 -40 -20 Temperature (°C) Pumping Capacity Meters Feet A=ULT-95, 60HZ B=ULT-95, 50HZ C=ULT-80, 60HZ D=ULT-80, 50HZ 16 Lpm 4.2 Gpm Flow Time to Temperature A=ULT-80, 60HZ B=ULT-95, 60HZ Time (Minutes) - 6 -...

Página 35: Section Iii Installation
Section III Installation Site The refrigeration system requires that the circulator must be located on a level surface. Never place the circulator in a location where excessive heat, moisture, or corrosive materials are present. Locate the circulator in a laboratory or clean industrial environment. Ambient Temperature Range 10°C to 35°C (50°F to 95°F) Overvoltage Category... -

Página 37: Plumbing Requirements
Plumbing Requirements Before installing the circulator to an instrument that previously used tap water as a cooling fluid, flush the instrument several times to remove any rust or scale that has built up. The manufacturer of the instrument should be able to recommend a cleaning fluid for their equipment. -
Página 38: Flow Control
Flow Control ULT 80s are equipped with a flow adjustment control knob. The knob is located directly in front of the control panel on the right side. When shipped, the flow is completely off. (Check that flow is off before starting.) To start flow, turn the knob in a counterclockwise direction until desired flow is obtained. -
Página 39: Section Iv Operation
Section IV Operation Start Up Before starting, check all electrical, plumbing, and inlet/outlet connections; and make sure the work area has been properly filled with bath fluid. To start the bath, place the MAIN ON/OFF switch to the ON position. The pump will start and the controller will display the temperature of the fluid in the reservoir. -
Página 40: Changing A Value
The REMOTE indicator illuminates whenever the circulator is configured to accept a remote setpoint. The controller's SENSOR indicator illuminates whenever the external sensor is selected. See Controller Displays on the next page. NEXT ENTER Use this key to scroll forward through the menus and also to accept and save changes. -
Página 41: Operator's Loop
Operator's Loop When the controller is first powered up it enters the Operator's Loop, displaying reservoir fluid temperature. Press the NEXT ENTER key to view the setpoint. SP displays the controller setpoint. The display will flash between SP and the actual setpoint number. - Página 42 tUnE = Tune HEAt = Heat PID Parameters Pro = Proportional Band (factory value 1.5%) Int = Integral (factory value 0.75 repeats per minute) dEr = Derivative (factory value 0.05 minutes) rtd = Sensor 1 = Internal 2 = External SP = Remote setpoint source, see page 18 Hit = High Temperature Limit Figure 2 Setup Loop (1 of 2)

Página 45: 9-Pin Accessory Connector
9-Pin Accessory Connector The circulator is equipped with two 9-pin D-connectors located on the rear of the control box. The female COMM is used for RS232 communication (see Appendix); the male is used with an optional external sensor. RS232 Pin Connections Pin # Function No connection. -
Página 46: Analog Interface
Analog Interface An 15-pin D subminiature female receptacle for analog interface is located on the rear of the control/pump box. ACCESSORY Pin # Function Chassis ground. No connection. 15 pin D-subminiature female receptacle 3 - 5 No connection. Analog Ground. The analog ground is physically separated from the power ground throughout the circulator. -
Página 47: Section V Maintenance & Troubleshooting
Section V Maintenance & Troubleshooting Service Contracts Service Contracts are designed to provide extended life and minimal down- time for your circulator. For more information, contact our Service Depart- ment. Cleaning Periodically inspect the reservoir. If cleaning is necessary, flush the reservoir with a cleaning fluid compatible with both the circulating system (if applicable) and the cooling fluid. - Página 48 Loss of Cooling Capacity Check cooling capacity specifications (see Section II, Specifications). Check temperature setpoint. Check to ensure that external heat load has not overcome the cooling capacity at the desired working temperature. If the circulator starts and no cooling occurs, listen for a clicking sound from the inside of the circulator.

Página 49: Service Assistance
No Temperature Control If recirculating to an external system, do not exceed the cooling capacity of the circulator. Exceeding the circulator's cooling capacity results in a loss of temperature control. No External Circulation On ULT 80s, make certain adjustable Flow Control is open (turn counter- clockwise). -

Página 53: Calibration Loop
Calibration Loop The Calibration Loop is used to calibrate the RTD high and low temperature. The controller's internal temperature sensor is factory calibrated. We recom- mend calibrating any external sensor. Enter the Calibration Loop from the Operator's Loop by pressing and holding the NO key while pressing the YES key three times. - Página 54 rtdn n= 1 = Internal sensor, n = 2 = external sensor rnH = High temperature rnL = Low temperature Ain = Analog in Aout = Analog out Stor = Store Figure 4 Calibration Loop NOTE: To stor all changes, when the display reads Stor press YES. Should you desire to return to the temperature display and abort all changes, when the display reads Stor press NO.
- Página 55 Appendix A Serial Communications Protocol NOTE: This appendix assumes you have a basic understanding of communi- cations protocols. All data is sent and received in binary form, do not use ASCII. In the following pages the binary data is represented in hexadecimal (hex) format. The NC Serial Communications Protocol is based on a master-slave model.
- Página 56 NC Serial Communications Protocol NOTE: All byte values are shown in hex, hex represents the binary values that must be sent to the bath. Do not use ASCII. The framing of the communications packet in both directions is: Checksum region Lead char Addr-MSB Addr-LSB Command...
- Página 57 The master sets parameters in the bath by sending one of the Set Functions as shown in Table 1. The master does not send a qualifier byte in the data field. The master should be preprogrammed to send the correct precision and units (it could also read the parameter of interest first to decode the correct precision and units needed).
