5.11.3 Force contact inputs

SETTINGS  TESTING  FORCE CONTACT INPUTS
 FORCE CONTACT
 INPUTS
The force contact inputs feature provides a method of performing checks on the function of all contact inputs.
While in Forcible test mode, the relay contact inputs can be pre-programmed to respond in the following ways:
• If set to "Normal," the input remains fully operational. It is controlled by the voltage across its input terminals and can
be turned on and off by external circuitry. Select this value if a given input must be operational during the test. This
includes, for example, an input initiating the test, or being a part of a user pre-programmed test sequence.
• If set to "Open," the input is forced to report as opened (Logic 0) while the operand selected by
setting is On, regardless of the voltage across the input terminals. While the selected operand is Off, the input behaves
as it does when in service.
• If set to "Closed," the input is forced to report as closed (Logic 1) while the operand selected by
setting is On regardless of the voltage across the input terminals. While the selected operand is Off, the input behaves
as it does when in service.
On restart, the

5.11.4 Force contact outputs

SETTINGS  TESTING  FORCE CONTACT OUTPUTS
 FORCE CONTACT
 OUTPUTS
The force contact outputs feature provides a method of performing checks on the function of all contact outputs.
While in Forcible test mode, the relay contact outputs can be pre-programmed to respond in the following ways:
• If set to "Normal," the contact output remains fully operational. It operates when its control operand is logic 1 and
resets when its control operand is logic 0.
• If set to "Energized," the output closes and remains closed while the operand selected by the
setting is On, regardless of the status of the operand configured to control the output contact. While the selected
operand is Off, the output behaves as it does when in service.
• If set to "De-energized," the output opens and remains opened while the operand selected by the
setting is On, regardless of the status of the operand configured to control the output contact. While the selected
operand is Off, the output behaves as it does when in service.
• If set to "Freeze," the output retains its position at the instant before the
operand selected by the
