GFD233A101 3BHE022294R0101 ABB processor module in stock

Description

GFD233A101 The 745 provides various diagnostic tools to verify the relay functionality. The normal

function of all output contacts can be overridden and forced to be energized or de

energized. Analog outputs may be forced GFD233A101 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

addition, 32 cycles of sampled current/voltage GFD233A101 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.

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 LED off and

the Test Mode LED on. Refer to FIGURE 5–49: GFD233A101 Output relays scheme logic on page 5–104 for

the output relay scheme logic.

FORCE OUTPUT RELAYS FUNCTION: Select “Enabled” to enable the output relay

testing feature and override normal output relay operation. This setpoint is defaulted

to “Disabled” at power on.

FORCE OUTPUT 1 to 8: Select “Energized” to force output 1(8) to the GFD233A101 energized state or

“De-energized” to force output 1(8) to the de-energized state. This setpoint is only

operational when output relay testing is enabled.

FORCE SELF-TEST RLY: 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.

The 745 has the ability to override the normal function GFD233A101 of analog transducer outputs,

forcing each to any level of its output range. Enabling this feature turns the Test Mode LED

on and de-energize the self-test relay.

FORCE ANALOG OUTPUT FUNCTION: Select “Enabled” to enable the analog output

testing and override the analog output normal operation. This setpoint defaults to

“Disabled” at power on.

FORCE ANALOG OUT 1(7): Enter the percentage GFD233A101 of the DC mA output range of analog

output 1(7). For example, if the analog output range has been programmed to 4 to 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.

When in simulation mode, protection features do not operate based on actual system

inputs. If simulation mode is used for field testing on equipment, other means of

protection must be provided by the operator.
