DELL X1052P switches

This is the method to be used when testing the 100/120V version (see Figure 1 for test circuit) and the 380/440V version with a step up transformer (see Figure 2 for test circuit). One pole of the switch (SW1) should be used to start the timer and one of the relay contacts used to stop the timer. Adjust the variac to give 130% of the setting voltage. Using switch SW1 change the voltage applied to the relay from zero to 130%. Measure and record the operating time.

This test method is for use 

when no step-up transformer is available for testing the 380/440V version. The test procedure is the same as for Method 1 but the applied voltages should be from zero to 130% and from zero to 200% of the actual pick-up voltage measured at the relay terminals (27 and 28) without the external resistor assembly in circuit (see Figure 3). The operating times should be within the limits given in Test Method 1.
