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
TEST MODE FORCING
to their default states.
