LEDs
Three LEDs are located on the front faceplate. The AC_OK LED
provides visual indication of the INPUT signal function. When
the LED is ON GREEN the power supply input is within normal
design limits.
When the DC_OK LED is GREEN the DC output is present.
When the FAULT_LED is RED then a fault condition exists and
the power supply may not provide output power. The table
below further defines these states:
I/O Expander option
The CAR1248FPx without extended i2c communications (blank
under the software option) has a single status/control byte I/O
expander that is accessible via address 0 x 4Eh (A2, A1, A0 are
pilled HI). This byte takes the form;
7 6 5 4 3 2 1 0
n/s n/s Fault ON/OFF Temp_OK n/s DCOK ACOK
n/s – not supported
Bits 0, 1, 3, and 5 are ‘read_only’ and are HI [1] during normal
operation. The rectifier needs to be biased externally in order to ‘read’
its operational state without the presence of input power.
Bit 4 is a ‘read/write’ bit that can be used to verify the ON/OFF
commanded state or change the commanded output of the rectifier.
In order to turn the output OFF this bit needs to be pulled LO [0].
No PEC support is provided. Standard i 2 c commands apply.
