SEL-351 Instruction Manual
Make corresponding, complementary text settings:
DP1_1 = 79 ENABLED
DP1_0 = 79 DISABLED
Display point setting DP1 controls the display of the text settings.
Reclosing Relay Enabled
In Figure 7.32, optoisolated input IN2 is energized to enable the reclosing relay, resulting in:
52A = IN1 = logical 1
DP1 = 52A = logical 1
This results in the display of corresponding text setting DP1_1 on the front-panel display:
79 ENABLED
Reclosing Relay Disabled
In Figure 7.32, optoisolated input IN2 is deenergized to disable the reclosing relay, resulting in:
DP1 = IN2 = logical 0
This results in the display of corresponding text setting DP1_0 on the front-panel display:
79 DISABLED
Circuit Breaker Status Indication
Make SELOGIC Control Equation display point setting DP2:
DP2 = 52A
Make corresponding, complementary text settings:
DP2_1 = BREAKER CLOSED
DP2_0 = BREAKER OPEN
Display point setting DP2 controls the display of the text settings.
