    There is a target and seal-in coil in series with the normally-open contact. The CCP13E relay is functionally equivalent to the CCP13D relay, but the two relays are not electrically interchangeable. There are differences in the output circuit arrangement s.

    GEK-65525 CONSTRUCT! ON The type CCP13E relay is mounted in an M2-size case. The case has studs at both The outline and panel drilling for this ends in the rear for external connections. case is shown in Figure 3. The electrical connections between the relay units and the case studs are made through stationary molded inner and outer blocks, between which nests a removable connection plug that completes the circuits.

    GEK-65525 A stainless ball is placed in the tube before the diaphragm is assembled. When the moving contact hits the stationary contact, the energy of the former is imparted to the latter and then to the ball, which is free to roll up the inclined tube. Thus, the moving contact comes to rest with substantially no rebound or vibration.

    GEK-65525 ACCEPTANCE TESTS Immediately upon receipt of the relay, an inspection and acceptance test should be made to make sure that no damage has been sustained in shipment and that the relay If the examination or test indicates that calibrations have not been disturbed. readjustment is necessary, refer to the section on SERVICING.

    (front view). Pickup The pickup of the CCP13E relay may be checked by applying rated voltage and frequency to the relay as in Figure 11. The relay should close its left contact at the current specified on the nameplate (relays are shipped with current pickup set to the minimum setting) multiplied by 1.15.

    GEK-65525 BEARINGS The lower jewel screw can be removed from the unit by means of an offset screwdriver or an end wrench. The jewel may be tested for cracks by exploring its surface with the point of a fine needle. If it is necessary to replace the jewel, a new pivot should be screwed into the bottom of the shaft at the same time.
