INST Characteristics - Continued
On 200 series relays, an additional delay of 0.1 second may be added
with internal switch SW8-2. This delay applies to both phase and
ground applications. Closing switch SW8-2 provides the additional
delay of 0.1 second.
Figure 1-4. Instantaneous Characteristic Curves
Time Characteristics Nine inverse time functions and one fixed time function can be selected
by a front panel switch. Characteristic curves for the inverse and
definite time functions are defined by the following equation.
