C: PRINCIPLE OF OPERATION Thank you for purchasing a Baldwin eCOOL™ Mini Digital Portable Gas Sample Conditioning System. All Baldwin coolers use thermo-electric elements (Peltiers) to cool the sample gas to the desired dew point temperature. A thermo-electric cooler is best illustrated as a small heat pump with no moving parts. The Peltiers operate on direct current and may be used for heating or cooling by reversing the direction of current flow.
transfer block is pumped to the heat sink where it is then dissipated into the air by the heat sink fan. See Figure 2. The desired temperature is maintained by a closed loop control system, which is implemented through a proportional controller. The controller uses a type K thermocouple in the heat transfer block located very close to the cold side of the peltier element as the input sensor.
D: INSTALLATION The eCOOL™ Mini should be located away from heat sources in a well ventilated area of an instrument rack or enclosure. Sample tubing connections to the eCOOL™ Mini depend on the heat exchanger material of construction. A cooler with stainless steel heat exchangers uses a stainless steel inlet fitting on the first heat exchanger. All other inlets and outlets are Kynar® standard compression type tube fittings with Teflon® ferrules.
E: START-UP PROCEDURE Plug in the power cord to a properly grounded main circuit. The LCD will display the actual temperature. The temperature of each heat exchanger will fall until it reaches approximately 5°C. If there are no alarms (an alarm condition consists of water slip detection after the cooler, thermocouple failure, or actual temperature > 10°C), then the LED(s) should turn to an amber color.
F: LEDS & LCD The eCOOL™ Mini has a jumbo 2-line LCD display and 2 LED indicators. Each of the two LED indicators corresponds to an active heat exchanger and will be colored Green, Amber, or Red: LED Summary GREEN: Status OK, Sampling can begin. Sample pump will run. AMBER: Alarm is no longer present. User must press the reset button to acknowledge the alarm and return to normal operation. Sample pump off. RED: Alarm - see message on LCD screen. Sample pump off.
G: BOARDS Control Board The control board is the motherboard for the eCOOL™ system. The control board handles the majority of the functions for the cooler module. It contains the microprocessor that controls all of the functional areas of the design, as well as the temperature measurement of the controlled vapor flow as well as the Pulse Width Modulation (PWM) control of the peltier modules to cool the vapor.
Main Control Board Overview Configuration Switches The configuration switches identify which components are connected to the system. They are used by the control firmware to determine how the board is going to operate in the system. The switches are read at power up, or when the external reset switch is activated. The table below identifies the switch positions and their functions.
SW2 Function ON OFF 1 ICE VCC Enabled Disabled 2 JTAG ICE ResetN Enabled Disabled 3 Calibration Enabled Normal Operation 4 Dflash Res Enabled Normal Operation 5 Init Clr Enabled Normal Operation Button Control The buttons are used to control the calibration settings. Follow the bottom line on the display to determine the functions in the different modes. The three combinations that are available are left only, right only, or both.
ChX: MIN = xx°C ChX: SPAN = xx°C ChX:MIN TMP= xx°C ChX:MAX TMP= xx°C ChX:SET TMP= xx°C ChX: GAIN=%3u Isolation Channels Min = 0°C Max = 25°C The temperature range for the isolation circuit is 0 to 25°C. The calibration is performed by first calculating a good starting point for the offset and span resistors. Then adjust the 0 point to the minimum point in the ADCC. The last step is to set the input to 25°C and adjust the span gain to achieve the max value in the ADCC.
H: DEFAULT SETPOINTS eCOOL Mini Heat Exchangers: Setpoint Temperature = 5°C Ready (Run) Temperature = 10°C Cooler must operate below the Ready Temperature to avoid the over temperature alarm condition. Relay Board: Relay contacts are in their Normal state (de-energized state) during an alarm condition. Analog output 0-4.5 VDC equates to 0-10°C corresponding to each thermocouple.
I: MAINTENANCE Note: Please refer to the Spare Parts section of this manual for part numbers and descriptions. Daily Verify each channel is running at 5°C (+/- 1.5°C). LED’s should be Green. Verify cooling fans are running. Verify that the peristaltic pump is running and water is draining out. Verify that the sample pump is drawing full flow. Quarterly Verify power supply voltage is above 14.5 VDC. Inspect and clean the EZ-Clean Twist-Apart heat exchangers with de-ionized water.
J: TROUBLESHOOTING Alarm Message Thermocouple Failure Channel # Water Slip Alarm Heat Exchanger (Channel) Over Temp Alarm Problem No LCD or LED(s) and no fan. Heat exchanger remains at ambient temperature. Heat exchanger frozen and cooler indicates ambient temperature. Heat exchanger does not reach set temperature, but is below ready temperature. Heat exchanger temperature cycles up and down. Water carryover in system. Pump does not start. LCD(s) are green.

APPENDIX: eCOOL™ MINI 19
Anko Peristaltic Drain Pump Series 810 Standard Features Electrical: 115 VAC, 60HZ with 6" leads. In a peristaltic pump (dispensing pump), the material to be pumped only comes in contact with the tubing. This is ideal for applications where the product to be moved or pumped should not touch any foreign materials. For example; dispensing slurries, dispensing food products, chemical or other difficult to handle fluids.
Series 810 General Specifications: Flow Rate: 50 fixed flow rates available - .4 to 987mL/min Mounting: 18 gauge zinc plated steel mounting plate. Dimensions: 5.12"W x 3.74"H x 4.1"D maximum. Motor: Shaded pole gearmotor Stainless steel output shaft Plastic cooling fan designed for operation at 25°C ambient temp. Pressures: Up to 20 psi (2.7 bar) Fluid Contacts: Fluid being dispensed contacts tubing only Pump: Polypropylene with stainless steel fasteners self priming up to 29 ft. (8.
