Board Configuration
The board operation is controlled through the bank of DIP Switches labeled SW1 located
on the component side of the board in the lower left corner. These switches must be set
for the cooler to operate properly. The switches numbered 1, 2, and 3 of the DIP switch
set the function of the board.

Basic Display Description
3 digit plus sign temperature display

Green LED to display ‘Ready’ status
Green LED to display ‘Water Slip’ status
Red LED to display ‘TC Fail’ status
Detailed Display Description
The digital display shows both temperature and status of the cooler.
The display will display temperature constantly when the impinger
temperature is below the user set ‘Ready’ temperature and no other faults
are present. One fault is the ‘Water Slip’, the sensing of liquid water
downstream of the sensor, though the use of a water slip sensor. The other
fault would be a ‘TC Failure’ indicating an open thermocouple sensor.
The display will blink the temperature when impinger temperature is
above the user set ‘Ready’ temperature and no other faults are present.
The display switches every second between blank and the temperature, in
this condition.
If a ‘Water Slip’ failure is detected the display will switch between
showing the measured temperature and a symbolic “SLP”. The display
switches every second between “WS” and the temperature.
If a ‘TC Failure’ is detected the display will switch between showing
blank and the letters “tcF”.
If both a ‘TC Failure’ and a ‘Water Slip’ failure are detected the display
will switch between showing the letters “tcF” and a symbolic “SLP”.
The display switches every second between “tcF” and “SLP”.
Detailed LED Description
The LED indicators show the status of the cooler.
The top LED, which is green, will turn on when impinger temperature is
below the user set ‘Ready’ temperature.
The top LED will turn off when impinger temperature is above the user set
‘Ready’ temperature.
The middle LED, which is green, will turn on there is not a ‘Water Slip’
failure showing the system is working correctly.
The middle LED will turn off when water is detected.
The bottom LED, which is red, will turn off there is not a ‘TC Failure’
showing the system is working correctly.
The bottom LED will turn on when an open condition is detected on the
thermocouple.
The operation of the ‘Ready’ and Water Slip’ indicators changes if the
user selects the relay latching option. Once the ‘Ready’ temperature is
reached for the first time the latching option goes into effect. If an alarm
occurs after the first ‘Ready’ indication the relays will remain off until the
user supplies a contact closure to the board to reset the alarm. The LED
indicators will blink when the alarm condition has been removed but the
relay has not yet been reset.

Outputs
Single Channel Cooler
The impinger temperature is available as a voltage output equal to 0.1 V / °C.
Analog out 1 is controlled by the temperature measured from thermocouple #1.
Each control board has two field replaceable relays.
Relay 1 is activated when the impinger temperature is below the user set ‘Ready’
temperature. The relay does not deactivate until the impinger temperature rises to
0.5 °C above the ‘Ready’ temperature. This hysteresis is set to avoid relay chatter
when the impinger is near the set temperature.
Relay 2 is activated when the ‘Water Slip’ sensor is dry and the system is working
properly. The relay is off when water is detected at the sensor.
Both relays have two sets of contacts. The standard factory wiring uses one set to
operate a sample pump. The second set of contacts is available for field wiring by
the user.
The relays can be selected to operate either in automatic reset or latching by the
user.

Switch Inputs
Single Channel Cooler
There are two dry contact inputs for each board labeled External Switches.
External Switch 1 will force the relays off even when there is no water present
and the impinger temperature is below ‘Ready’. This can be used to keep the
sample pump from turning on as soon as the cooler is ready to allow for other
portions of the system to become ready for sampling.
External Switch 2 will reset the latched alarms. This switch is only active when
the Relay = Latch option is selected in set up.

Calibration
Overview
Each board must be calibrated before use. The calibration consist of several steps
including setting the Cold Junction temperature, calibrating the thermocouple
input for channel 1 and 2, and calibrating the voltage output 1 and 2.
A volt meter and a thermocouple calibrator are required for the operations.
The cold junction temperature should be set first prior to the thermocouple
calibration.
Cold Junction Temperature
Turn both #5 and #6 switches to the ‘ON’ position of the DIP Switch labeled
SW1. The display will toggle between a label of ‘ cJt’ and the value of the board
temperature. The label ‘ cJt’ will be displayed for 1 second followed by the value
of the board temperature for 3 seconds.
Measure the temperature of the board near the thermocouple connectors. Adjust
the displayed temperature using the ‘UP’ or ‘DOWN’ buttons. When the
temperature displayed matches the measured value; move switches #5 and #6 to
the ‘OFF’ position to record the value.

calibration. The front digital display will go blank. The back indicator LED lights
will be lit and display the calibration stage.
