NOTE
Set the CHARACTERISTIC ANGLE by adjusting one end point of the 180° trip region. In
Figure 5-12, the test current lags the CHARACTERISTIC ANGLE by 90°.
Figure 5-12. Directional Setting
Step 3.
Connect a counter to monitor the time interval from initiation of the timing condition to the output
transition.
Step 4.
Switch the sensing current from 0.0 amperes to 3.75 amperes (LOW range) or 11.25 amperes
(HIGH range). (This is 5 times the level set in step 2.) Monitor the time required to energize the
output contacts and compare that time with the value in Table 5-2.
Step 5.
Adjust the TIME DIAL to 10 and repeat step 4.
This completes relay verification testing.
DIRECTIONAL SETTING PROCEDURE
Characteristic Angle
For switch selectable controls (options 3-2 or 3-4), simply turn the control to the desired setting in accordance
with the markings on the front panel.
For potentiometer controls (options 3-1, 3-3, 3-5, or 3-6), perform the following steps:
Step 1.
Perform the preliminary setup procedures at the beginning of this section.
Step 2.
With the CHARACTERISTIC ANGLE set to minimum, apply a voltage input of 120 Vac at a phase
angle of 0° and a current input of 1.0 ampere (LOW range) or 3.0 amperes (HIGH range) at a
lagging phase angle equal to the desired CHARACTERISTIC ANGLE setting. The appropriate
phase INHIBIT LED should be ON.
Step 3.
Slowly rotate the CHARACTERISTIC ANGLE control
CW to the position where the appropriate phase
INHIBIT LED lights.

Limited Region Of Operation
If the relay includes the LIMITED REGION OF OPERATION
option, perform the following steps. If this option is not included,
continue with
Verifying The Setting
.
Step 4.
Apply a voltage input of 120 Vac at a phase angle of
0° and a current input of 1.0 ampere (LOW range) or
3.0 amperes (HIGH range) at a phase angle defined
by the following equation.
