control may also be shifted to the bridge control 

 console, but may be reclaimed by the engine room 

 personnel at any time. 



Boiler Section 



The boiler section (fig. 25-16) contains the 

 necessary pressure, temperature, and level in- 

 dicators and alarms for monitoring boiler oper- 

 ation. Also mounted is an underwater log speed 

 indicator and a sound-powered telephone handset 

 and jack. Actual boiler control is accomplished 

 by a Bailey boiler control console (not shown). 



Auxiliaries Section 



The auxiliaries section (fig. 25-17) provides 

 for remote operation (start and stop) of such 



equipment as fire pumps, condensate and circu- 

 lating pumps, and ventilation systems. It also 

 monitors nonvital systems such as potable water, 

 air conditioning, and refrigeration. This section 

 also contains three digital demand meters. These 

 meters will display, upon demand, any one or any 

 three simultaneously, of approximately 170 dif- 

 ferent readings relating to the boilers, fuel and 

 lube oil, main condensers, main turbines, ship 

 service generators, and auxiliary machinery. To 

 obtain a reading, the operator looks up the num- 

 ber (address) of the function he wishes to read 

 on the function address nameplate located on the 

 data logger section and turns a thumbwheel 

 switch beside the digital demand meter to this 

 address. The meter will then display the value 

 of the function selected. The same function may 

 be selected and read on all three meters or three
