功能描述

　　1.由駕駛室向機艙傳達主機轉速命令及由機艙回答命令執行情況的設備。

　　2.CCL應急主機傳令鐘共分十一檔：進一、進二、進三、進四、備車、停車、完車、退一、退二、退三、退四。

　　3.在特殊的情況下，由機艙傳達主機現行速度的命令，而駕駛室回答命令。

　　4.誤車報警：主機齒輪箱檢測到轉向信號與應急主機傳令鐘收信器所要求操作的進退方向相反時，應急主機傳令鐘發信器發出誤車報警信號。主機齒輪箱信號由應急主機傳令鐘收信器輸入檢測判斷。

　　5.失電報警：當其中一路電掉電時，自動轉到另外一路電源，應急主機傳令鐘發信器發出失電報警聲光信號。

　　6.調光：可隨外界光線強弱調節駕駛室應急主機傳令鐘發信器面板上指示燈。

　　7.帶VDR(RS485)接口

　　8.應急主機傳令鐘收信器輸出一付無源閉合觸電和一付有源觸電（DC24V 1A）

　　Functional Description

　　The system orders the main engine speed from wheel house to Engine room respond the speed from Engine room to Wheel house.

　　In event of special condition,the present speed of main engine can be sent from engine room to Wheel house,and respond from wheel house.

　　CCL Emergency Telegraph has 11 levels:forehead1、forehead2、forehead3、forehead4、stand by、stop、finished、astern1、astern2、astern3、astern4.

　　Order error alarm:When the forward or astern signal is not synchronous detection by gear case of M/E and Emergency main engine telegraph receiver,The emergency main engine telegraph transmitter will seed out order error alarm signal,Signal of M/E’s gear case must be estimate obey the input detection signal of Emergency main engine telegraph receiver.

　　Power failure alarm:when the main power is fault,It could switchover to emergency power automatically ,and Emergency main engine telegraph transmite send out visual and audio signal of power failure alarm

　　Light adjustable：the indicator in the wheel house panel can be adjuste

　　VDR(RS485)

　　Emergency main engine telegraph receiver output a pair of passive closed contact and o pair of active contcact(DC24V  1A).
