UT20 and UT30 Tower-based Weather Stations

8.1.2 CR1000 Datalogger

The CR1000 datalogger and PS100 12 V power supply mount to the enclosure

backplate as shown in FIGURE 8-5. Two screws (pn 447) attach the CR1000,

four screws (pn 505) attach the PS100.

8.1.3 BPALK Alkaline Power Supply

The BPALK battery pack houses eight alkaline “D” cell batteries (FIGURE

8-4). To install the batteries, loosen the thumb screw and remove the cover.

1. Make sure the red and black wires attached to the left end of the BPALK

are connected to the “12 V” and “G” terminals on the CR1000.

2. Disconnect the battery pack from the external connector on the left end of

the BPALK. Remove the battery pack and insert eight alkaline “D” cell

batteries. Replace the battery pack.

3. Connect the battery pack to the external connector labeled “INTERNAL

BATTERY” and replace the cover.

8.1.4 PS100 Rechargeable Power Supply

The PS100 houses a sealed monoblock rechargeable battery. To install the

battery, loosen the two thumb screws and remove the cover.

1. With the PS100 power switch “OFF”, insert the battery and plug the

battery lead into the connector labeled “INT”.

2. Make sure the red and black wires attached to the “+12 V” and “

”

terminals on the PS100 are connected to the “12 V” and “G” terminals on

the CR1000 Wiring Panel.

3. An AC transformer or unregulated solar panel (Section 8.1.5, SP10 Solar

Panel) should be connected to the PS100 at all times. Connect the lead

wires from the transformer or solar panel without regard to polarity to the

two terminals labeled “CHG” (FIGURE 8-5); the red LED should light

when voltage is present.

The wall transformer converts 120 Vac input to 18 Vac output.

Maximum charging current is 1.1 A.

Maximum input voltage into the “CHG” terminals is 26

Vac or 26 Vdc. Do not connect 110 Vac directly to

“CHG” terminals.

4. Turn power switch to “ON”, and replace cover.
