3.5 Mains Isolation Transformer
Mains Supply is provided by the Master Switch Unit to the Mains Isolation Transformer via a 32A
Isolator (Controller Switch), detailed in paragraph 3.4. The Transformer need not be specified
separately, as it is contained within the Outercase, chosen from Table 5. The Transformer Wiring
Terminal block is shown in Figure 11 Figure 12 and Figure
11 Figure 12. The appropriate supply should be selected from
the terminal block. Full procedures on mains supply selection is detailed in Document
667/HB/32750/000. Output from the mains transformer is input to PL9 on the Backplane Board;
please refer to paragraph 3.2.2 above.

3.6 Manual Panel PED Full
The Manual Panel (P/N 667/1/27056/002) is mounted within a secure position on both large and
small cabinet. This unit does not form part of the Outercase, chosen from Table 5, and therefore
should be specified separately. When the full Manual Panel is not specified a simple switch
pedestrian panel is fitted, to allow the traffic lights to be switched on and off. Please refer to
document 667/HB/32750/000 for more information on this unit. The 34 way ribbon cable from
manual panel connects into socket X2 on the CPU PCB. The detector fault monitoring LED
indicator is repeated from the manual panel to the Outercase by the use of a lens. The lens kit
(P/N 667/1/27104/000) should only be specified when the full manual panel is specified.

Note: When the full manual panel (shown) is fitted, the magnet is fitted to the
door to operate the door open switch.
