1、Switching between local and remote control position is through the “local / remote”
rotating switching which in thruster starter.
Notice:
There will must to stop the main motor, fan, oil pump and sea water pump before
change local to remote or change remote to local.
2、When system is stand in remote control mode，whether bridge or DP/JOY can
control thruster. But DP/JOY control permissions are priority, (Note : when the
control right in DP/JOY, W/H FWD and W/H AFT control lever should be placed in
the zero position. )
1) System power on and the control right default in W/H AFT.
2) DP/JOY send request signal, then the system must satisfy: ①In remote
control mode ② Follow up control ③Thruster running ④Thruster is normal, these
four conditions satisfy, then sends ready signal automatically and agrees to transfer
control right.
3) When DP/JOY request signal interrupt or other problem result in losing the
control right. At this point control right default in W/H AFT control.
4）When system is stand in remote control mode and DP / JOY not request
control, W/H FWD or W/H AFT are allow to gain the control right..
2.3.2
Control Mode Switching
In remote control mode, the system has two control modes:
1）Follow up control mode
Output the pitch command value by DP/JOY or bridge lever, then PLC
program compares it with pitch feedback value. If there have a difference, it
gives a new control signal, then drives solenoid valve to take (left or right)
action.
Attention: when “PITCH FEEDBACK SIGNAL FAIL Alarm” appears, the
pitch meter shows the pitch value is zero, but the actual pitch value remain
unchanged, follow up control mode failed, you can switch to non follow up
control mode to operate the pitch at that time.
2）Non follow up control mode
By pressing "PORT" and "STBD" buttons to open loop control, it sends
control signals directly to drive the corresponding solenoid valve to take (left
or right) action. When control signal stops, the pitch stop changing.

stop.
2、Before starting the main motor of thruster, the system must satisfy: 1）power
available 2）pitch neutral 3）hyd. oil pump running 4）vent fan running 5）sea
water pump running 6) ready to start.
2.3.4
Automatically change control mode
Follow up control mode will invalidation when PLC is failure, thruster pitch would
remain the same value, and control mode automatically transfers to non follow up
control mode and you will see the group lamps of non follow up are light on. (Note: if
PLC is failure, system stand in non follow up control mode, but this time pitch
feedback value and motor load value can’t be displayed.)

Where applicable; check the following parts of the system each 6-month period:
a Check cables and cable entrances for damage to the cable.
b Tighten all electrical screw-terminals.
c Tighten all plug connections.
Yearly maintenance
Visual inspection of system parts is recommended to prevent malfunctions and to
ensure safe operation. Each year, check and if necessary calibrate the input sensors
and output actuators according to the manufacturer’s instructions. In general, it is not
necessary to re-calibrate sensors if the input signal is correct.

System failure analysis
1: When operating control lever, the pitch command value of touch screen (meter) has
no change or is not normal.
a: Check whether communication is normal, if the communication between PLC and
touch screen is failure, the message “COMMUNICATION ERROR X” will appear
on the top left corner of the HMI; ERROR 0：communication error with 1#BT,
ERROR 1：communication error with 2#BT, ERROR 2：communication error with ST.
b: Check whether PLC is normal, in Parameter setting interface, observed the value in
“display”, if it changes that PLC is normal.
c: In Parameter setting page, observed whether the control lever setting value of
“PORT（SET）”、”NEUTRAL（SET）”、”STBD（SET）” is normal.
d: Direct measurement the input signal from control lever of PLC side , if the input
signal is not normal , you need to check the control lever supply voltage “"± 10V" is
normal.
2: The touch screen page can not switch.
Restart the touch screen, if the fault is still exists required to replace the touch
screen.
3: PLC input signal is normal, but the state does not reflect normal.

For example, the main power supply and the main power supply feedback signal is
normal, but the touch screen displays the main power loss, it need to check whether
the
voltage is normal.
4: The output light of PLC is normal, but the state does not reflect normal.
For example the lamp
to check whether
of PLC is light, but the buzzer did not ring, you need
and
voltage is normal.
