10.1.2
PCI/PCIA Electrical Power Requirements
1)
100Vac - 120Vac, 10VA from a mains supply for the 115V switch position.
2)
200Vac - 250Vac, 10VA from a mains supply for the 230V switch position.
3)
9 - 30Vdc, 55mA from an external low voltage supply for the anemometer (excluding
analogue outputs).
4)
8 - 18Vdc, 50mA max from an external low voltage supply for the interface box only.
3 fuses protect the unit:
1.
Externally accessible
1 A (T) for 115/230v operation.
2.
Internally accessible
500 mA (T) AUX.
3.
Internally accessible
500 mA (T) ANEM.
10.1.3
PCI/PCIA Operation.
There are three Red LED’s on the PCI/PCIA front panel.
When the PCI/PCIA box is powered the Power LED will illuminate.
When a R3 is connected as above to the PCI/PCIA box and is set to output continuous data the box
RX LED will flash on/off at the R3 output rate thus giving a good indication that the R3 output is
wired to the correctly and outputting RS422 data correctly.
If the PCI/PCIA RS 232 connection is connected to a computer then when a terminal programme is
opened and commands sent by a PC keypad or program to the box its TX LED will illuminate
intermittently indicating a good connection between the PC and the box. Connector Pin and Cable
Assignments for PCI/PCIA are as follows:-.
