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
configured to control the output contact. While the selected operand is Off, the output behaves as it does when in
service.
