Configuration check

Based on the configuration of power source 1 and power source 2, the module
calculates the configuration check.
The configuration check is activated if any of the condition is true.
• The power source 1 is configured as generator.
• The power source 1 is configured for busbar number other than 1.
• The power source 2 is configured as generator.
• The power source 2 is configured for busbar number other than 1 or 2.
If the configuration check is activated, the CONFIG_ERROR output is TRUE, else the
CONFIG_ERROR output is FALSE.
The configuration check signals for the power source 1 and power source 2 are
provided to the Source 1/source 2 LS data handle module.

Test request logic

Based on the test modes of PML630s installed in the adjacent electrical network areas,
PML630 can be configured to the test mode if the TEST_REQUEST output is
activated.
Table 305 shows the calculation of the TEST_REQUEST output with respect to the
Disable test request setting and various inputs.

This module calculates the load-shedding enable signals ENA_PPLS1 and
ENA_PPLS2 for adjacent electrical areas. These status signals determine whether the
load-shedding data of the corresponding adjacent electrical network areas are
considered or not.
Table 306 shows the calculation of the ENA_PPLS1 status signal for electrical
network area 1. Similarly, the ENA_PPLS2 is calculated for electrical network area
2.
