Pickup and Dropout Test
1.
Connect relay terminals 1 and 11 to a DC source using a load box to control the
current over a range of 0.1 to 2 amperes.
2.
Close the left contact manually.
3.
Increase the current slowly until the seal-in unit picks up.
The target must latch in.
4.
Decrease the current slowly until the seal-in unit drops out.
The target must remain latched in.

The location of the relay should be clean and dry, free from dust, excessive heat
and vibration, and should be well-lighted to facilitate inspection and testing.
The relay should be mounted on a vertical surface.
