Sea Trials
7.1
Full Speed Setting - Servo Throttle
A Warm-up the engine(s) and transmission(s) and slowly move into open water.
B Gradually move the lever(s) to Full speed.
C If synchronization is installed, disable synchronization as explained in Section Section 2.10.4: Turning
Synchronization OFF:.
• If the engine RPM is low, check whether the engine throttle lever is against the full speed
stop.
• If the engine RPM is high, decrease by using Function Code E3, as explained in Section
Section 5.7.0.1.3: Function Code E3 – Throttle Maximum.
D For twin screw applications, check that matching Idle, Mid-range and Full speed Control Head lever
positions cause equal RPM in both engines.
• If RPM’s do not match, check push-pull cable travel. If travel does not match when the Control
Head levers are side by side, adjust Function Code E3 refer to Section Section 5.7.0.1.3:
Function Code E3 – Throttle Maximum.
7.2
Full Speed Setting - Electronic Throttle
A Warm-up the engine(s) and transmission(s) and slowly move into open water.
B Gradually move the lever(s) to Full speed.
C If synchronization is installed, disable synchronization as explained in Section Section 5.7.0.0.2:
Function Code E7 – Synchronization.
• If the engine RPM is low, refer to the MM13927 Field Service Test Unit Reference Manual.
• If the engine RPM is high, decrease by using Function Code
E3
, as explained in Section
Section 5.7.0.1.3: Function Code E3 – Throttle Maximum.
D For twin screw applications, check that matching Idle, Mid-range and Full speed Control Head lever
positions cause equal RPM in both engines.
7.3
Proportional Pause
The proportional pause feature provides engine deceleration when making a direction change. The pause is
variable and in proportion to:
• The Control Head’s lever position prior to the reversal.
• How long the Control Head’s lever has been in that position prior to the reversal.
The pause is In-Gear or at Neutral, depending on the Function Code
C2
Proportional Pause setting. The
sequence of events, are as follows for the three different Reversal Pause types:
7.3.1
In-Gear Delay [C200]
• The Throttle position drops to Idle.
• The Transmission remains engaged in Ahead or Astern.
• The Control System pauses at this position until the delay has timed out.
• The Transmission shifts to the opposite gear (Astern or Ahead).
• The Throttle position moves to the Control Head’s present lever position.
WARNING: It is imperative that the information provided in the previous Sections has been read and followed
precisely, prior to attempting a Sea Trial. If any of the following tests fail, discontinue the Sea Trial immediately
and return to the dock. Consult Section Troubleshooting or a ZF Facility prior to resuming the Sea Trial.
NOTE: On twin screw applications, the following tests must be performed on both sides. During the course of
the Dock Trial and Sea Trials, fill out the Trial Report. Retain this information for future use.
