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

Temperature is displayed in tenths of °C

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.

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”. The single ‘Water Slip’ alarm will be displayed on both channels. A single channel, channel 1, can be constantly displayed be selecting the switch option in set up and omitting the switch. Detailed LED Description The LED indicators show the current channel being displayed.

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 active 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.

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. The unit can be set to have the ‘Water Slip’ input to control the relays in several ways. The ‘Water Slip’ can; Control Relay1 in conjunction with ‘Ready’ on channel 1 Control Relay2 in conjunction with ‘Ready’ on channel 2 Control Relay2 alone Both relays have two sets of contacts. The standard factory wiring uses one set to operate a sample pump.
PAGE 9
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. 1St Frozen There are two dry contact inputs for each board labeled External Switches.

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.
