The Explorer 2 LSS combines two previously separate components found in the Explorer 1 design, the LSS (Life Support System) and the Sensor Array. This design change allows for more robust communications between these two previously separate components, while maintaining the ease of use, cleaning and storage of the Explorer 1 design.

TEMPSTICK (THERMISTOR ARRAY)

1. The thermistor array is detatchable from the LSS for ease of transport and storage. It connects to the LSS using a 6-pin, keyed Molex® Connector. The male pins are in the thermistor array and the female connector is sealed in the center shaft of the LSS (fig 1).

2. The thermistor array is held in place by one O-Ring which is located in the top groove at the base of the thermistor array (fig 2).

NOTE: Do not put the O-Ring in the bottom groove of the thermistor array. Doing so may make correctly mating the Molex® connectors more difficult.

3. To install the thermistor array, look for the key on the Molex® connector in the LSS. It will look like a small extrusion on the outside of the connector. Line up the keyway on the Molex® connector of the Thermistor array and push down gently on the array until the flange on the array bottoms out on the LSS.

CAUTION: DO NOT use force to mate the array to the LSS. The array should seat quite easily into the LSS. If they are not mating up easily, that probably means you do not have the pieces aligned properly.

OXYGEN SENSORS (3)

3. The three (3) oxygen sensors (PSR-11-39-MD) are mated to the LSS using 3-pin Molex® Connectors. The male connector is in the O2 Sensor and the female connector is in the LSS. You will notice that the female Molex® Connector mounted in the LSS is a half-moon shape. Looking at the male Molex® Connector in the O2 Sensor, you will see a white tab extending from the base of the 3 pins slightly past the end of the 3 pins. The white tab mates to the flat surface of the female Molex® Connector in the LSS.

4. To mount the O2 Sensors in the LSS, line the

white tab on the sensor up to the flat area on the LSS connector and push down gently until you feel the sensor bottom out on the LSS body (fig 3).

CAUTION: DO NOT twist the sensor into the LSS in an attempt to mate the sensor to the connector in the LSS. Doing so may bend the pins in the O2 Sensor, rendering it unusable. DO NOT attempt to straighten pins that have been bent as that WILL make the sensor unreliable.

WARNING: Using damaged, worn or outdated sensors can lead to serious injury, or even death.

CARBON DIOXIDE SENSOR (CO2 SENSOR)

5. The Carbon Dioxide Sensor attaches to the LSS using a 3.5mm Pin Jack (fig 4).

6. To install the CO2 sensor, simply put the sensor into the CO2 sensor plug and push down gently on the sides of the sensor until it seats onto the 3.5mm Pin Jack (fig. 5).

CAUTION: DO NOT touch the white membrane on the CO2 sensor face with your fingers as that would leave a residue of oils which may occlude the sensor membrane.

7. Once the CO2 sensor is firmly seated on the pin, take the Sensor Cover/Dessicant Holder, check to make sure the O-Ring is in the groove at its base, then place the Sensor Cover/Dessicant Holder on top of the sensor and push down until it is firmly in place (fig. 6).

CHARGING THE LSS

8. To charge the LSS, locate the arrow on the charger and plug it into the LSS with the arrow pointing to the cover screw directly above the charging port of the LSS. Turn the cover of the charger slightly clockwise

to lock the charger onto the charging port of the LSS (fig. 7).

NOTE: If the batteries are fully discharged, the charging light on the LSS may take a few minutes to come on. Leave the LSS charging whenever it is not in use.
