The ICOOL has one green and one red LED operating indicators. These indicators are arranged horizontally on the front of the cooler. The green LED indicates the READY operating temperature status, normally set for 3.5°C (38°F). After the set-point temperature is reached, the sample pump may be turned on by the internal relay. When the impinger temperature is below 10°C (50°F) the ready LED will be on. At one degree above the set temperature, the ready LED will be off. The red LED is the thermistor failure indicator. When this occurs, the red LED stays illuminated.
The ICOOL cooler has an analog voltage output, the connector is found on the bottom left side of the cooler marked TEMP OUT. This output is factory standard at 0-5 VDC = 0-20°C (0.25 V / °C).
The ICOOL cooler has a relay output, the connector is found on the bottom of the cooler marked RELAY OUT. This output is Form C, rated for 10 AMP @ 250 VAC.
