5.8 S6 TESTING

The 745 provides various diagnostic tools to verify the relay functionality. The normal function of all output con-
tacts can be overridden and forced to be energized or de-energized. Analog outputs may be forced to any level
of their output range. The simulation feature allows system parameters (magnitudes and angles) to be entered
as setpoints and made to generate fault conditions without the necessity of any system connections. In addi-
tion, 16 cycles of sampled current/voltage waveform data (in IEEE Comtrade file format) can be loaded and
"played back" to test the response of the 745 under any (previously recorded) system disturbance.

SS S6 TESTING
The 745 has the ability to override the normal function of all outputs, forcing each to energize and de-energize
for testing. Enabling this feature turns the IN SERVICE indicator off and the TEST MODE indicator on.

De-energized
The 745 has the ability to override the normal function of analog transducer outputs, forcing each to any level
of its output range. Enabling this feature turns the TEST MODE indicator on and de-energize the self-test relay.

This message indicates the start of the OUTPUT RELAYS section. To continue
these setpoints press
EN TE R
Range: Disabled / Enabled
Select Enabled to enable the output relay testing feature and override normal
output relay operation. This setpoint is defaulted to Disabled at power on.
Range: De-energized / Energized
Select Energized to force Output 1 (2-8) to the energized state. Select De-
energized to force Output 1 (2-8) to the de-energized state. This setpoint is
only operational while the output relay testing feature is enabled.
Range: De-energized / Energized
Select Energized to force the self-test relay to the energized state and De-
energized to force to the de-energized state. This setpoint is only operational
while the output relay testing feature is enabled.
This message indicates the start of the ANALOG OUTPUTS section. To continue
these setpoints press
EN TE R
Range: Disabled / Enabled
Select Enabled to enable the analog output testing and override the analog
output normal operation. This setpoint defaults to Disabled at power on.
Range: 0 to 100 (steps of 1)
Enter the percentage of the DC mA output range of Analog Output 1 (2–7).
For example, if the analog output range has been programmed to 4-20 mA,
entering 100% outputs 20 mA, 0% outputs 4 mA, and 50% outputs 12 mA.
This setpoint is only operational if analog output testing is enabled.
