Section 3. Instrumentation Installation
3.1.4 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 3.1-5) 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 3.1-4); 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. NOTE
Maximum input voltage into the "CHG" terminals is 26
VAC or 26 VDC. Do not connect 110 VAC directly to
"CHG" terminals. WARNING
4. Turn power switch to "ON", and replace cover.
3.1.5 Solar Panel
Solar panels purchased from CSI are shipped with a charge plug taped to the
back of the panel. The charge plug is not used with the PS100. Refer to the
solar panel manual for installation instructions.
1. Mount the solar panel to the mast, facing south (northern hemisphere).
Position the solar panel at the top of the 1 1/4 inch diameter section of the
mast. Install using its mounting hardware (see Figure 3.1-5).
2. The solar panel should be oriented to receive maximum insolation over the
course of the year. Suggested tilt angles (referenced to the horizontal
plane) are listed below.
Site Latitude Tilt Angle
0 - 10 degrees 10 degrees
11 - 20 Latitude + 5 degrees
21 - 45 Latitude + 10 degrees
46 - 65 Latitude + 15 degrees
> 65 80 degrees
3. After determining the tilt angle, loosen the two bolts that attach the
mounting bracket to the panel. Adjust the angle, then tighten the bolts.
Secure the lead wire to the mast using wire ties.
