LENCO 123SC Operating instructions

If you have no lights,
proceed to
“System Inoperative”
Operate the system in TEST MODE.
• If the system works in the Test Mode there is a problem with the accessory signal.
Check for proper connection to the orange accessory wire of the control box.
• If the system does not work in Test Mode continue to Step 2.
Verify there is 12V or 24V at the Power Plug: Disconnect the Power Plug from the control box’s power
and measure voltage using a DC voltmeter.
• If 12V or 24V is not at the Power Plug across the two pins,
step 1: Check the fuse or circuit breaker (between
battery and control box)
step 2:
step 3:
step 4: Check battery switch.
• If 12V or 24V is at the Power Plug across the two pins,
Check the key pad connection.
Call Lenco Marine for further technical assistance.
SYSTEM INOPERATIVE (Power Fault)
NOTE:Under normal operation the control box’s orange accessory wire requires a 12V level
or a tachometer signal to turn the control box ON (top triangular LEDs on switch are lit)
Step 1:
Step 2:
Verify that the power connection is firmly
attached and that 12 or 24 volts is available.
Verify the Orange wire is connected to a 12
or 24V source or an Engine Tach Signal.

Lenco actuators come with 6FT actuator cables that feature Deutsch terminations.
Boat builders may use a separate wire harness connecting power and actuators to control box.
If you’re not certain if there is a separate connection in your boat, contact the boat manufacturer.
This guide is intended to provide basic functional diagnostics and will assist in determining
the source of the problem. Choose Power Fault or Actuator Fault and follow the steps.
If you have this reading
and are still experiencing
a problem, call Lenco.

Press and hold all four keypad buttons down for approximately
three seconds. The LEDs on the keypad should track down than back up
and stop with the top triangular LED lit on each side.
Press the left side button on the keypad labeled “DOWN”. The
starboard actuator should extend and the left side indicating lights should
track.
Press the right side button on the keypad labeled “UP”. The port
actuator should extend and the right side indicating lights should track.
Momentarily press all four keypad buttons down simultaneously.
Both actuators should retract fully and keypad should have no indicating
lights on.

Step B:
Press the left-side button on the switch labeled “DOWN”. The starboard actuator
should extend and the left-side indicator lights should track.
Press the right-side button on the switch labeled “UP”. The port actuator should
extend and the right-side indicator lights should track.
• If fault reading is present at the opposite side of the key pad, the actuator (or its
connections) may be defective. Proceed to Step 4.
• If fault reading is present at the same side of the key pad, the control box may be
defective. Call Lenco Marine for

Remove the wire leads
from the connector by
depressing the small
latch inside the
connector housing.
Extend the Actuator:

Step 4: If fault continues, disconnect the Deutsch Connectors and remove the
orange wedge.
Step 5: Remove the wire leads from the connector by depressing the small
latches inside the connector housing and pulling on the wire leads.
Step 6: Once the wires are removed from the housing, touch the white wire
leads to a Positive (+) 12V Battery Terminal and the black wire leads
to a Negative (-) 12V Battery Terminal. The actuator should extend
while connected to the battery. Reverse the polarity of the wire leads
to the battery terminals and the actuator should retract.
If the actuator does not extend and retract, replace the actuator.
If the actuator extends and retracts properly, re-assemble the
connector taking care to properly seat the wire leads into the
connector housing. Proceed to Step 7.
Step 7: Attach the port and starboard connectors to the system. If the fault reading continues,
