3.3 Optional
Equipment
The following optional equipment is available to enhance the system capabilities:
Digital Slave Display(s) (see 3.3.1)
Printer
(see
3.3.2)
Connection Box (see 3.3.3)
Transducer(s) (see 3.3.4)
Switch Box (see 3.3.5)
3.3.1
Digital Slave Display(s)
These are used to repeat water depth information at other parts of the ship where
such information is needed. A total of two Digital Slave Displays can be connected
directly to the system.
Echosounding systems and remote indicators which detect and display the
water depth from a single momentary value per transmission pulse, e.g.
digital and pointer displays, can, over a period of time, display false readings.
This is primarily valid in shallow water areas. For this reason, water depths
displayed in this manner must be compared with the graphic presentation at
regular intervals in order to guarantee the ship's safety.
CAUTION!
While crossing steep slopes the echo evaluation might fail.
A steady depth display cannot be guaranteed in this case.
The depth display will show the last evaluated depth value together with a
question mark; longer lasting errors will be indicated by a question mark
without any depth value.
At the digital slave display "----" will be displayed in this case.
3.3.2 Printer
A printer can be connected to give a continuous hard copy of data presented on the
display or to print out a hard copy of events from any time within the previous 24 hour
operating period.
3.3.3
Optional Connection Box
The optional Connection Box (see Figure 3-2) is connected to the Display and Control
Unit and provides the following connections:
a second Digital Slave Display
a blanking pulse output
depth alarm relay contacts (potential free)
