Clutch
The clutch should not slip at rated voltage and 10 amperes when the relay is
connected as in Figure 2. See the
SERVICING
section for clutch adjustment.
HIG H-SEISMIC TARGET AND SEAL-IN UNIT
The target and seal-in unit has an operating coil tapped at 0.2 and 2.0 amperes.
The relay is shipped from the factory with the tap screw in the higher ampere
position. The tap screw is the screw holding the right-hand stationary contact. To
change the tap setting, first remove one screw from the left-hand stationary contact
and place it in the desired tap. Next remove the screw from the undesired tap and
place it on the left-hand stationary contact where the first screw was removed. See
Figure 8.
This procedure is necessary to prevent the right-hand stationary contact
from getting out of adjustment.
Screws should
never
be left in
both
taps at the
same time.
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.
See Table IV.
The target must latch in.
4.
Decrease the current slowly until the seal-in unit drops out.
See Table IV.
The target must remain latched in.
Reset the target before checking pickup
again.

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.
The outline and panel-drilling
dimensions are shown in Figure 3.
The internal connections of the CCP13E are shown in Figure 5. An elementary diagram
of typical external connections is shown in Figure 2.
One of the mounting studs or screws should be permanently grounded by a conductor
not less than No.12 B&S gauge copper wire or its equivalent.
