Table 6: Executing the auto-config
Commissioning
The device status LEDs flash
alternately red and green on all
Marex ECS components.
The auto-config is running. The process
may take a few minutes.
When the LEDs flash green on all
components, the auto-config is
finished.
4. Reattach the auto-config plug to the
corresponding jack on the wiring
harness. Make sure the plug fits
securely. The configuration is complete.
The device status LED’s are indicating
the components’ status again. The
control unit is ready for operation.
Repeat the auto-config if the process
is interrupted or red LEDs flash or
light up permanently.
If you wish to modify settings you can now make the necessary
changes using the wireless MarexLink network.
5. Test all system functions first at standstill and later at slow
speed. Refer to the Marex ECS Quick Guide.
The commissioning is complete if all functions are working
without failure.

clicked into place.
If the ship or remote control system is subjected to heavy
vibrations, you will need to inspect more frequently the cable
and screw connections to terminals, plugs and fastening points.
9.3 Maintenance
The Marex ECS Control Unit is basically maintenance-free.
Servicing the control unit extends to cleaning and inspecting the
exterior. The following safety instructions must be observed:

Disassembly and replacement
10 Disassembly and replacement
CAUTION
Injury hazard due to improper disassembly or replacement
Stored residual energy, sharp parts, points and corners on
and in the component or on the required tools can cause
injuries. If you replace the Marex ECS Control Unit while the
ship is cruising, the ability to steer may be lost
O Disassemble or replace the Marex ECS Control Unit only
in the habour or at the jetty.

troubleshooting
Malfunctions are signaled to the operator by the ALARM LEDs
and the device status LEDs on the control head’s keypad.
WARNING
Hazard of a fatal accident or collision due to a system
failure
When ALARM LEDs flash red or light up permanently this
indicates a device failure or malfunction which may result in
a system failure or even unexpected reaction of the boat.
You may no longer be able to control the main propulsion
engine. To prevent a fatal accident or collision, immediately
take the following measures when the ALARM LED flashes
or lights up:
O First bring the boat into a safe state!
O Only then acknowledge the alarm and eliminate the
cause of the fault
If the active control head fails, Marex ECS automatically
reduces the engine rpm to idle and disengages the clutch.
12.1 Take control or change the control station
Provided your Marex ECS features more than one control head,
you can control your boat from another control head should the
active control head fail. Choose a control head of which the
device status LED lights up green and push the COMMAND key
twice in order to activate it.
If this is not possible, change to the local control of the
propulsion system, if available.

Error search and troubleshooting
12.2 Alarm signals and acknowledgment
If the ALARM LED of your control head flashes red
accompanied by the buzzer:
O Bring the boat into a safe state!
O Acknowledge the alarm by pushing the ALARM key. The
buzzer is muted and the ALARM LED changes its state:
– If the ALARM LED permanently lights up red, you have to
take troubleshooting measures immediately.
– Even if the ALARM LED turns off, you must check the
function of system and components immediately!
Twin-engine systems provide one ALARM LED each for port
and starboard. In case of alarm, only one may flash or light
up permanently. Then the failure only concerns one of the
propulsion systems and the other propulsion side is not
affected.

Error search and troubleshooting
12.3 Troubleshooting the control head
In case of malfunctions, check the LEDs on the control head(s)
and, if applicable, actuator(s) and carry out the corresponding
steps as explained in the tables below:
Table 7: LED signals on the control head
LED-signal Meaning What to do
This control head is defective. O Replace the control head and repeat the
auto-configuration (see also chapter 8.1 and
the documentation for the Marex ECS
Control Head).
O If available, check also the function of the
other control heads by comparing the LED
signals and referring to the instructions in
this table.
O If available, check the function of the optional
actuator(s), see table 8.
This control head works fine,
but another system component
is defective.
O If available, check the function of the other
control heads, by comparing the LED signals
and referring to the instructions in this table.
O If available, check the function of the optional
actuator(s), see table 8.
The communication of the
control head has failed or the
power supply is beyond the
admissible range.
Power supply failure. O Check the power supply, see also chapter
Do you still have the command and can control
engine and gear?
O Check the on-board power supply.
If not,
O check the STATION cables, see also chapter
7.3.

12.4 Troubleshooting the actuator
In case of an alarm signal on the Marex ECS control head, it may
be necessary to check the condition of the actuator(s). Two LEDs
are provided under the transparent cover of the actuator to
indicate its functional condition Compare the LED signals to the
indications in the table below:
Table 8: LED-signals on the actuator
LED-signal Meaning What to do
This actuator is defective. O Replace the actuator, proceed as described in the
actuator’s documentation and repeat the
Marex ECS auto-config (8.1).
This actuator works fine, but
another actuator may be
affected.
The actuator has stopped
working due to overload.
Power supply failure or the
power is beyond the admissible
range or the communication
between the actuator and the
control unit is disturbed.
O Check the function of all other actuators, if
available. Refer to the instructions in this table.
O Check manually if the actuator’s adjusting lever
can move freely by pulling the push/pull cable.
O Eliminate the cause of the stiff movement.
O Dis- and reconnect the POWER cable and try again.
O Check the PROPULSION cable for proper
connection and visible damage. Replace the cable
if defective.
O Measure the voltage at battery and system
components. Pay special attention to correct
polarity and fuses.
O Make sure the wiring harness is properly
connected to the control unit with the retaining
catches clicked into place.
