C: PRINCIPLE OF OPERATION Thank you for purchasing a Perma Pure Baldwin™-Series Thermo-Electric Cooler. This Modular Series features a unique slim design leaving additional space to install or access other sample conditioning system components. A unique drop-down door on the Modular Series provides easy access to electronic boards and the power supply. All electronic boards (control, relay, and display) are mounted on the door for easy access.
316L stainless steel), PVDF (Kynar), or glass, is mounted within a thermally insulated heat transfer block bored to receive the heat exchanger without a mechanical lock. This assembly allows the easy removal of any heat exchanger simply by slipping it out of the cooling block by hand. The heat transfer block cools the heat exchanger through the heat pumping action of the peltier element.
D: INSTALLATION The Model M325 should be installed away from heat sources in a well ventilated area of an instrument rack or enclosure. The more stable the ambient temperature environment around the Model M325, the better the output dew point stability. Sample tubing connections to the Model M325 depend on the heat exchanger material of construction. A cooler with a stainless steel heat exchanger uses a stainless steel inlet fitting.
E: START-UP PROCEDURE Plug in the power cord to a properly grounded main circuit. The Ready Green LED will come on within 3 minutes, indicating the relay temperature (10°C) has been achieved. After approximately 3 minutes, the set point of +5°C. (41°F) is achieved. The SLIP Green LED should also be on if a water slip sensor is connected to the internal relay board. The sample gas flow may be started immediately after the READY Green LED comes on. The Model M325 is virtually maintenance free.
F: LED INDICATORS The Model M325 has two green and one red LED operating indicators. These indicators are arranged vertically on the front of the cooler. The bottom green LED indicates the READY operating temperature status, normally set for 10°C (50°F). After the set-point temperature is reached, the sample pump may be turned on by other devices. When the impinger temperature is below 10°C (50°F) the ready LED will be on. Above this temperature, the ready LED will be off.
G: I/O TERMINAL BLOCK DESCRIPTION The I/O terminal blocks are found on the bottom panel of the cooler: TB1 TB1 is the standard analog output (low voltage DC output) for all Modular Series Thermo-Electric Coolers. Model M325 is a single-channel cooler with one passive and one active 5” heat exchanger connected in series. The output is 0vdc to 2.5vdc for a temperature range of 0°C to 25°C. C Terminal 1 is earth ground.
H: TEST & ADJUSTMENT PROCEDURES NOTE: All test and adjustment procedures have been performed at the factory. Therefore, no adjustment should be necessary. A. Main Control board (1) WARNING: Before connecting power to the cooler, be aware of the HAZARDOUS LIVE VOLTAGE on the control board. Disconnect power from the cooler before opening the swing-down "L-door". Note: The auxiliary output board must be removed if the cooler is so equipped. Remove the thermocouples from TB1 and TB2.
B. Display Board (1) WARNING: Before connecting power to the cooler, be aware of the HAZARDOUS LIVE VOLTAGE on the control board. Disconnect power from the cooler before opening the swing-down "L-door". Remove display cover from the front of the swing-down "L-door". Connect a voltmeter between the ground test point, TP7 on the main control board and TP1 on the display board, the red lead to TP1 and the black lead to TP7.
For Current Output (3a) If the auxiliary analog output board is set up for current output, set the ammeter to 200ma range. Connect the ammeter to TB1 (the channel 1 current output terminal), the black lead to the negative (-) terminal and the red lead to the positive (+) terminal. (4a) Adjust POT4 (the zero pot) to obtain a 4mA reading on the ammeter. (5a) Set the thermocouple generator to 25°C. (6a) Adjust POT1 (the span pot) to obtain a 20mA reading on the ammeter.
I: DESCRIPTION OF OPTIONS Baldwin Modular Series Thermo-Electric Coolers have three available options: (1) temperature display; (2) alarm relay/water slip, and (3) auxiliary analog output. Modular Series Coolers may be equipped with any one or all of the options. All external I/O connections for these options are available through the terminal blocks on the bottom of the cooler. 1. Display Option (standard on model M325) The display option is a secondary board that is mounted on the main control board.
J: “NEW JERSEY” THERMOCOUPLE OPTION Some air quality management districts (e.g., those in New Jersey and Southern California) require temperature measurement of the gas stream at the outlet of the last heat exchanger on the cooler. Perma Pure offers a 1/32-inch diameter hypodermic-style type K thermocouple that can be inserted into a special heat exchanger (i.e., it has a small port for insertion of the thermocouple) so the actual sample dew point temperature can be measured.
K: TROUBLESHOOTING Symptom No LED(s) and no fan. Check AC power input. No LED(s) and fan on. AC input fuse on control board. DC output fuse on control board. VC on control board. Action Ensure that AC power is connected. Replace fuse as necessary. Replace fuse as necessary. Replace control board. LED(s) on and no fan. AC input fuse on power supply. +12vdc TB4 on control board. Replace fuse as necessary. Replace power supply. Impinger remains at ambient temperature. Thermocouple failure LED is on.
