CS10-L and CS15-L Current Transformers

5.6 CR10X with Multiplexer Sample Program

This program uses the CR10X and an AM16/32-series multiplexer to read 32

CS10-L current transformers.

;{CR10X}

; Example program for CS10-L

;

; Program to test the CS10-L or CS15-L sensor on a CR10X datalogger

; and AM1632 Multiplexer.

*Table 1 Program

01: 30 Execution Interval (seconds)

; Turn on the multiplexer

1: Do (P86)

1: 41 Set Port 1 High

2: Excitation with Delay (P22)

1: 1 Ex Channel

2: 0 Delay W/Ex (0.01 sec units)

3: 15 Delay After Ex (0.01 sec units)

4: 0 mV Excitation

3: Beginning of Loop (P87)

1: 0000 Delay

2: 32 Loop Count

; Clock multiplexer to next channel

4: Do (P86)

1: 72 Pulse Port 2

5: Excitation with Delay (P22)

1: 1 Ex Channel

2: 0 Delay W/Ex (0.01 sec units)

3: 1 Delay After Ex (0.01 sec units)

4: 0 mV Excitation

6: Do (P86)

1: 1 Call Subroutine 1

; This part of the program will calculate the RMS Amperage

; Standard Deviation in this part of the code works mathematically the same

; as RMS calculation, and it is easier to program this way. The RMS

; value is calculated and stored back into an input location for further

; processing if needed.

7: Do (P86)
