Installation Procedure
PHASE
Positioning the Actuators
1. Choose a point close enough to the hydraulic distributor to fix the mounting brackets, ensuring
that the movements of the machine on’t interfere in any ay ith the ne parts applied.
2. The actuator mounting brackets provided ith the actuator installation kit must be assembled to
a surface that has a thickness of at least 10 mm and a idth of at least 60 mm.
3. The bracket should be ell fixed to the truck structure, free from any mechanical bending or
distortions. Bolting is preferable to elding (operation ho ever allo ed in those cases in hich
there aren’t the conditions to avoid it). The mounting and installation might take a longer hen
using bolts. Ho ever there are many benefits during initial setting up of the installation and its
maintenance hen taking the bolt fixing approach.
The follo ing pictures sho some installation cases. Pictures are intended for illustration purposes only.
"Since various truck manufacturers exist and trucks from same manufacturer tend to vary as ell, it is
recommended to consider each installation a ne case by itself".

NOTES
1. Carefully align the mechanical support for the actuator assembly before it is tightened in place
using M6 bolts. The rods should slide freely and ith some residual backlash. It is al ays
recommended to fix the brackets from one end before fixing one or more motors and connecting
them to the corresponding forks and clamping them to the transmission rods. Once the optimum
alignment is reached, complete the final fixing.
2. Actuators have a springs return to centre position. It’s important to lock the clamp on the rod of
the double commands only after having bounded it to the actuator. In this ay the neutral
position of the motor ill correspond exactly to the one of the distributor, ensuring a correct
return to 0 position and ith the totally available on both the directions of movement.
3. The fixing kit includes 5 mm bolts ith self-locking head properly tightened during the assembly
of the mounting brackets to prevent the accidental loosening of mounts.
IMPORTANT
Any accidental loosening could considerably alter the radio control function and/or damage the
mechanical assembly.
4. Applications hich do not require multiple motors installed in parallel on same mounting bracket
offer a higher degree of flexibility during installation. Each motor can be aligned accurately along
the direction of the force to be applied in order to ensure precise and reliable movement.
5. The ne design of the MEC-HL-C actuators, thanks to a further reduced cross-section, facilitates
the positioning in situations here the space is drastically reduced.

INSTALLATION MANUAL | MEC-HL C

6. An optional universal KIT, (Easy Kit), can be used in the direct application on the levers. Special
do els are inserted on the base of each lever. Connections bet een these do els and the forks
on the modules are done by a set of connecting rods designed and made based on the machine
specifications. The goal is to compensate the centre-to-centre distance difference bet een the
various levers and the set of modules, along ith the need to convert an angular motion (lever)
into a linear motion (module). The connecting rods are manufactured ith an offset bet een the
t o sockets to distribute the centre-to-centre difference progressively. As a result the
misalignment ill be extremely reduced thus ensuring smooth operation.
PHASE 2
Placement of the Receiver
The receiver should be placed in an open space on the edge of the truck avoiding close proximity or
interference ith the back of the vibrating cabin or the deck. The support seating of the receiver must be
such that a minimum of 150 mm along the 70-pole / 30pol connector area is available to facilitate
assembly and removal of same connector.
The receiver should be placed allo ing the diagnostic LED's to be completely visible by the operator.
Hetronic can provide as optional the supports of the receivers.
Figure 4. Placement of the Recei er

INSTALLATION MANUAL | MEC-HL C

Placement of the Key Switch Box
It is possible to use the same seating to mount the STOP button and the operation selector radio or manual
unit, hich are part of the supplied iring.
The STOP button has to be placed so that it can be easily activated by the operator in the event is necessary
to turn off the receiver.
Figure 5. Placement of the Key Switch Box
PHASE 3
Cable Positioning
There is enough cable length provided in the MEC-HL kit to reach all of the connection points of the
different devices on the truck.
Note in the figure the possibility to mount the actuators also ith independent positioning and separated
brackets.
This flexibility is sometimes the only ay to reach a proper end result.
