 TESTING 

OPERATIONAL TEST PROCEDURE 

The following test procedure verifies operation and calibration of the relay. Note that the results obtained 
from this procedure may not fall strictly within specified tolerances. When evaluating results, consider the 
inherent error of test equipment. Test equipment should be accurate within 1% or better. 

Step 1.  On the logic board (left side), find S1 and set S1-4 to ON (down) and all other switches to OFF 

(up). 

Step 2.  Apply appropriate operating power to terminals 3 and 4. Verify that the POWER LED is ON and 

power supply status contacts (if supplied) are open. 

Step 3.  Apply a variable source of ac current to phase A, terminals 13 and 14. Range of current source 

should be appropriate to the sensing input range. 

Step 4.  Turn the phase pickup adjustment fully CCW. From near zero, slowly increase current from the 

variable current source until the current pickup indicator on front panel lights. Measure the 
current. It should be at or below the low end of the sensing input range. 

Step 5.  Turn the phase pickup adjustment fully CW. Slowly increase current until the current pickup 

indicator lights. Measure the current. It should be at or above the high end of the sensing input 
range. 

Step 6.  Repeat steps 3 (substitute appropriate terminals for terminals 13 and 14), 4, and 5 for each 

phase and neutral (if supplied). Note that the neutral sensing input range may be different than 
the phase sensing input range. 

Step 7.  Set the control timer to its maximum period (potentiometer fully CW). Set timers T1 and T2 to 

their minimum period (both potentiometers fully CCW). 

Step 8.  Provide a means for monitoring contact closure for the three BF outputs (terminals 1 and 10, 2 

and 5, 11 and 12). If current operated targets are supplied, there must be at least 0.2 A flowing 
through the contacts when closed. Reset targets (if supplied). 

Step 9.  Apply a current to any sensing input so that the current pickup indicator LED is ON. Then apply 

a simulated BFI signal to terminals 6 and 7, observing the requirements of isolated and non-
isolated contact sensing. BF1, BF2, and BF3 contacts should close briefly. Also, the BF1 and 
BF2 targets (if supplied) should be tripped. Remove sensing input current. Reset targets (if 
supplied). 

Step 10.  If supervisory contact sensing is supplied, perform this step. If not, continue testing with Step 

11. Apply a current to any sensing input so that the current pickup indicator LED is ON. Apply a 
simulated BFI signal to terminals 6 and 7 and a simulated 52a (supervisory) signal to terminals 
8 and 9, observing the requirements of contact sensing. BF1, BF2, and BF3 contacts should 
close briefly. Also, the BF1 and BF2 targets should be tripped. Reset targets (if supplied). 

Step 11.  If an instantaneous output is not supplied, omit all remaining tests. If supplied, provide a monitor 

for contact terminals 11 and 12. For current operated targets, use at least 0.2 A current flowing 
through the contacts. 

Step 12.  Set switch S1-1 to ON and all other switches (S1-2 through S1-8) to OFF. 

Step 13.  With no current applied to any sensing inputs, apply a simulated BFI signal to terminals 6 and 7. 

Instantaneous contacts should close briefly and the INST target should be tripped. Reset target. 

Step 14.  If supervisory contact sensing is supplied, open switch S1-1 and S1-2. With no current applied 

to any sensing inputs, apply a simulated supervisory signal to terminals 8 and 9. Instantaneous 
contacts should close briefly and INST target should be tripped. Reset target. 

CAUTION 

Before performing the following tests, refer to the relay operating precautions in 
Section 4.
