emergency cutout valve provides the console operator a positive control to prevent the launch valve from opening during a HANGFIRE condition. When placed in the emergency position, the cutout valve electrically and hydraulically shifts the launch valve control system to the closed position. Central Junction Box The central junction provides a single location for the  catapult  control  system  wiring  and  relays.  The terminal board and all wires are clearly marked for easy identification. Relay status lights and a relay tester aid in troubleshooting electrical malfunctions. Deckedge Signal Box The  deckedge  signal  box  (fig.  4-65)  is  located  at flight deck level adjacent to the deckedge control panel. Its function is to indicate the readiness of the catapult to the launching officer during operations. Water Brake Control Panel The  water  brake  control  panel  (see  fig.  4-59)  is located in the water brake pump room. In the event of an  emergency  or  malfunction  of  the  water  brakes,  a switch   on   the   panel   is   used   to   suspend   catapult operations  and  it  is  further  protection  for  personnel when access to the launching engine cylinders or water brake cylinder is required. Main Control Console (CV-63) The  main  control  console  (fig.  4-66)  is  used  in conjunction  with  the  deckedge  control  panel  during catapult  operation.  The  control  console  consists  of  an operating  panel,  an  emergency  panel,  a  malfunction panel,  two  gauge  panels,  a  launch  valve  cutout  valve, and the transfer switch enclosure. OPERATING  PANEL.—The  operating  panel  is used  in  conjunction  with  the  deckedge  panel  during launching operations. It contains the lights, push  buttons,  and  switches  that  are  used  for  catapult control during the launching sequence. EMERGENCY PANEL.—The emergency panel contains  all  the  lights,  push  buttons,  and  switches  are required   to   provide   complete   control   during   the launching, retraction, and bridle tensioning phases. STEAM  GAUGE  PANEL.—The   steam   gauge panel  contains  a  steam  pressure  gauge,  CSV  setting controls,  digital  endspeed  indicator  and  launch  valve timer displays. GAUGE  PANEL.—The  gauge  panel  provides  a means of monitoring steam and hydraulic temperature and pressures. MALFUNCTION   PANEL.—The    malfunction panel contains lights that indicate the status of certain catapult components or systems. The hydraulic pressure  and  the  valve  position  malfunction  lights  are 4-53 INTER LOCK ON FIRST READY STAND BY FINAL READY FIRE ABEf0466 Figure 4-65.—Deckedge signal box.
