Table 11. Terms and Operators for Function Channel Program Lines
Relay and LED Channel: The relay and LED channel’s program line (79 characters maximum) determines the conditions that will cause a
specific relay to energize, or a specific status LED indicator to illuminate. A complete program line consists of a relay or LED channel
number on the left side of the equation, and a set of conditions (Boolean logic expressions) which will cause the relay to energize, or the
LED to illuminate on the right side of the equation. The left and right sides of the equation are separated by an equal sign (=). Table 12
lists acceptable terms (and definitions) for the left and right sides of a program line equation. The right side terms are joined by
operators, also listed in Table 12.
The program line of any relay or LED channel can be entered or revised when configuring the relay or LED channels using the command
CONFIG, or by using the command SET PROGRAM.
Note: A relay output assigned to an Energy Management channel cannot be controlled by a program line.
Note: When the LMS1000 is used in a 582140000, 582140001, and 582126100 NETSURE Power System that communicates to the LMS1000
using the LISP port, option channel L7 is dedicated to provide an ‘External Fuse Alarm’ indication and channel L8 is dedicated to provide
an ‘External AC Fail Alarm’ indication to the Power System MCA. Any state generated by the program lines of these channels will be
passed to the MCA as an ‘External Fuse Alarm’ and an ‘External AC Fail Alarm’ indication respectively.
