3.25 Factory Setpoints
When the 169 relay is shipped it will have all setpoints stored in its non-volatile memory. The factory setpoints
represent values for an average large three phase motor. The preset Relay and System Configurations represent
the most common output relay configurations and attributes. These values are meant to be used as a starting point
for programming the relay and should be changed as each application requires.
In the event of a non-volatile memory failure, which will be detected by the self-test feature (see section 3.23), the
169 relay will reload the factory setpoints but will not provide motor protection.
A list of the motor current, RTD, and overload curve setpoints is given in Table 3-6. For other factory setpoints see
Tables 3-7 and 3-3.
