DEIF TAP-210DG/3 Channel input module

DEIF TAP-210DG/3 Channel input module

This test has checked the calibration point of the relay and the other settings need only be checked to see that they are functioning. Refer to tests 2 – 6 in Table 1 for the appropriate switch positions. With the dropper resistors (REXT2) still out of circuit, monitor the voltage at the relay terminals (27, 28). Slowly increase the voltage until the relay picks up (when the green timer start led is fully illuminated). The measured pick-up values should be higher than the pick-up value on the lowest setting (400V) as indicated below. Take the pick-up value at 400V as being X.

MVTD 13 neutral displacement relay

A series dropper resistor of approximately 50kΩ is required to obtain sufficient accuracy in determining the pick-up value of the relay. Check that the trip indicator is reset and slowly increase the ac voltage until the green timer start led on the frontplate is fully illuminated. Record the pick-up voltage. Repeat the test for each of the settings shown in Table 1. The allowable errors on the voltage settings are ±2% on the lowest setting and ± 4% on all other settings. (No allowance has been made for instrument errors).
