2.2 GENERAL SETTINGS
401: EXPONENT - Exponent x to use in I
EXPONENT can be set from 1 to 2 in steps of 0.1. Use a value that matches the specific breaker used in the
application.
402: MAX_OP - Maximum Number Of Breaker Operations Permitted
This number can be set from 0 to 9999. Enter the maximum number of operations that the breaker can tolerate
2
before maintenance is required.
403: MAX_IXT - Maximum Breaker Duty
This number can be entered in the range of 0 to 999.9M in steps of 0.1K. Enter a number equal to the maxi-
mum duty recommended by the breaker manufacturer. Index Flag 139: Breaker Equipment Duty Alarm
(BRMNDT) is set when the Breaker duty equals 80% of the set value. This flag may be directly assigned to an
output contact or used in configurable logic.
404: IXTPHASEA - Accumulated Duty, Breaker Phase A
IXTPHASEA can be set over the range of 0 to 999.9M with a step of 0.1K. If the accumulated duty to that point
in time is known, enter that value, otherwise, enter an estimated value or use the default value of zero (0).
405: IXTPHASEB - Accumulated Duty, Breaker Phase B
IXTPHASEB can be set over the range of 0 to 999.9M with a step of 0.1K. If the accumulated duty to that point
in time is known, enter that value, otherwise, enter an estimated value or use the default value of zero (0).
406: IXTPHASEC - Accumulated Duty, Breaker Phase C
IXTPHASEC can be set over the range of 0 to 999.9M with a step of 0.1K. If the accumulated duty to that point
in time is known, enter that value, otherwise, enter an estimated value or use the default value of zero (0).
407: NUM_OP - Present Number Of Breaker Operations
NUM_OP can be set over the range of 0 to 9999 with a step of 1. If the number of operations to that point in
time is know, enter that value, otherwise, enter an estimated value or use the default value of zero (0). Index
Flag 138: Number of Breaker Operations Alarm (BRMNOP) is set when the Breaker duty equals the set value.
This flag may be directly assigned to an output contact or used in configurable logic.
There are twelve contact converters provided in the LPS-O relay. These contact converters are used to convert
contact inputs into logic signals for use within scheme logic. Each of the contact converters can be pro-
grammed to be driven by any of the signals defined by the first 32 Index Numbers listed in Table 2–5: INDEX
NUMBERS – CONTACT CONVERTER INPUT ASSIGNMENT on page 2–32.
501: CC1 - Contact Converter 1
502: CC2 - Contact Converter 2
503: CC3 - Contact Converter 3
504: CC4 - Contact Converter 4
505: CC5 - Contact Converter 5
506: CC6 - Contact Converter 6
Use any of the first 32 signals given in Table 2–5 on page 2–32 to define the function of any of the 12 contact
converters
