Figure 15: Switching power supply output voltage graph
Finding the output voltage using the graph
1. Indicate the probe temperature on the
TEMPERATURE (°C) axis.
2. Draw a line from the temperature value point
up to the curve
a)
and draw a line from the
intersection point across to the VOLTAGE (V)
axis.
3. Adjust the output voltage of the switching
power supply to the resultant value. For
example, if the probe temperature is 22°C, the
output voltage of the switching power supply
must be set at 27.4 V.
Figure 16: Switching power supply output voltage chart
Finding the output voltage using the chart
1. Select the nearest value to the probe
temperature on the TEMPERATURE (°C) row.
2. Read the respective value on the VOLTAGE (V)
row.
3. Adjust the output voltage of the switching
power supply to the indicated value. For
example, if the probe temperature is 22 °C,
the output voltage of the switching power
supply must be set at 27.4 V.
Installing the FC500IP board
Install the IP module into the base of the control
panel, as shown in Figure 17. Follow these
instructions to install the FC500IP board.
CAUTION:
•
Before installing the FC500IP
module, disconnect the
control panel from its power
supply, the mains, and the
batteries.
•
You must connect the IP
module to the earth of the
electricity supply system.
•
You must insert the earth
cable (item 10) between the
fixing bracket of the module,
the screw (item 5) and the
earth terminal (item 11).
