The Z unit is a clapper type auxiliary relay (standard SG) with one make contact, Z10, and make-break contacts, Z11 and Z OPERATION Operation of the relay and associated equipment will be described, using the external schematic in Figure 7, in conjunction with Figures 4 and 5, which show contact positions as a function of the drum position. The Type SC line of relays are adjustable over a wide range of current. Each relay is provided with a mechanical operation indicator and a calibrated scale to indicate the pick-up setting. The high drop-out to pick-up ratio (%) of the Type SC relays make them particularly suitable for use as fault detectors to supervise main protective relays.

The principal component parts of the relay and their location are shown in Figures 1 through 5. ELECTROMAGNET The electromagnets for the types CO-5, CO-6, CO-7, CO-8 and CO-9 relays have a main tapped coil located on the center leg of an “E” type laminat-ed structure that produces a flux which divides and returns through the outer legs. SC and SC-1 relays have been provided with tapped coils to meet this requirement. The coil taps are brought out to a tap block mounted on the lower end of the relay frame or on the relay sub-base, depend-ing on the type of case used. The connector plate on the tap block is marked with the minimum pickup value of each tap and the shunt is. The Z unit is a clapper type auxiliary relay (standard SG) with one make contact, Z10, and make-break contacts, Z11 and Z OPERATION Operation of the relay and associated equipment will be described, using the external schematic in Figure 7, in conjunction with Figures 4 and 5, which show contact positions as a function of the drum position.

not be construed as a commitment by ABB Flexible Automation Inc. ABB The 24 VDC will not energize the relay until the 0 VDC. The core, shunt and plunger construction also pro- vides the high ratio of dropout to pickup in the SC and. SV relays. This ratio is above 90% for any pickup. according to ABB Remote monitoring portal user's manual If the PVS is equipped with an emergency stop relay (option +Q), SC INV 1 U (23B0).
