Step 2.
Adjust the BE1-40Q Relay for the desired pickup value as specified by the generator
application or the test setup capabilities.
Step 3.
Adjust the TIME DELAY switches to a minimum value (e.g., 0.1, 0.2, or 0.3 seconds).
Step 4.
Adjust the voltage source to the nominal value of the sensing input as designated by the
second digit of the style number, at a leading phase angle of 150

Characteristics Data
Step 1.
Adjust the current source phase angle for each of the values indicated in Table 5-3. Record
the magnitude of current required to receive each pickup indication. To measure pickup for
each phase angle setting, slowly increase the current magnitude from zero or a value less
than the pickup value until the PICKUP LED lights and an output contact operation occurs.

Step 2.
With the above recorded data, calculate P (watts) and Q (vars), as follows, for each recorded
pickup value.
