CENTRAL PROCESSOR PACKAGE INSTALLATION

2.16CONNECTION TO AUXILIARY CONTROL FUNCTIONS (14 Card Central Cabinet)

The 14 card Central Processor can accommodate only one Auxiliary Control Relay card with a maxi- mum of 16 relays. A somewhat different relay mounting arrangement is used due to space limita- tions. Relays 1 through 8 are mounted vertically with RY1 at the bottom of the mounting strip. Note care- fully the location of the COIL terminals; the relay sockets are rotated 900 clockwise from the

CPU main Relay Panel as shown in Figure 2-14.The TDM-AUX/E8 accessory provides relays 9 through 16, just as in the larger cabinets. In this pack- age however, the accessory relay strip is stacked above the primary relay strip as shown in Figure 2-14with addition of AUX/E8.

The A and B control inputs are contained on a circuit board which mounts on the sidewall of the relay housing to the left of the primary relay strip. All control functions are identical to those shown for larger CPP cabinets.
