SECTION 5 • TESTING
INTRODUCTION
The following procedures verify proper relay operation and calibration.
Results obtained from these procedures may no fall within specified tolerances. When evaluating results,
consider three prominent factors:
•
Test equipment accuracy
• Testing method
• External test set components tolerance level
OPERATIONAL TEST
Step 1. Perform test setup (Figure 5-1) and apply power to the relay. Verify that the POWER LED is
ON, and that the power supply status contact is open.
Figure 5-1. Typical Test Setup
Step 2. Set all TIME DIALS (if any) to the zero position.
Step 3. Connect an ac voltage source (50 or 60 Hz, depending upon input option) to input terminals 6
and 7. Adjust this voltage to equal the desired overvoltage pickup level.
