EVLJBOX HP Sequencer - Application manual
Introduction
The EVLJBOX HP Sequencer is a control solution housed in an
electric panel that makes it possible to control in sequence up
to 5 heat pumps managed by programmable EVCO devices and
interconnected with RS-485 serial communications systems.
The number of operating units and their power level are adjusted
according to the cooling/heating requirements of the equipment,
but it is also possible to set parameters for the number of units
active at the same time.
The fully IP65-compliant panel houses a user interface with a LCD
graphic display with a resolution of 320x240 pixels and 16 colours,
from which it is possible to manage all the main functions of the
equipment (switch on/off, alter operating mode, etc.) and view the
main variables of each of the connected heat pumps.

Installation
INSTALLATION PRECAUTIONS
–Ensure that the working conditions are within the limits stated in the “Technical specications” section.
–Do not install the device close to heat sources, equipment with a strong magnetic eld, in places subject to direct
sunlight, rain, damp, excessive dust, mechanical vibrations or shocks.
–In compliance with safety regulations, the device must be installed properly to ensure adequate protection from
contact with electrical parts. All protective parts must be xed in such a way as to need the aid of a tool to remove
them.
–Users will need a rigid pipe tting; the maximum diameter of the xing hole must be 28.5 mm
–To ensure IP65-rated protection of the whole casing, x the container using only the holes already made
Wall mounting
1. Secure the back cover |7| to the wall using the 4 screws
|1|
and the holes already made |6|
2. Make sure the seal |8| is correctly inserted
3. Place the front cover |4| over the back cover
|7| and push the 2 assembling tongues |10|
down into the holes |2| on the right or left
of the front cover |4|
4. Fix the user interface |12| into place by pressing it
into its housing |5| from the front
5. Fix the control module |14| to the DIN rail |16|;
next secure the DIN rail |16| to the back cover
|7| in its housing |17| with two screws |15|
6. If the connection cables are fed in from above,
make a hole whose diameter is suitable for xing
a rigid pipe tting |13| on the top of the
back cover |7|; if the cables are fed in from the
bottom, make the hole on the bottom of the cover
7. Screw the rigid pipe tting |13| to the back
cover |7|
8. Connect the user interface |12| as shown in the
section “Electrical connections”, feeding the
connection cables through the rigid pipe tting |13|
9. Secure the front cover |4| to the back cover |7|
using the 4 screws |9| and the holes already made |3|
10. Fix the covering strips |11| over the top and bottom
parts of the front cover |4|

Electrical connections
PRECAUTIONS FOR ELECTRICAL CONNECTIONS
–Use cables of an adequate section for the current running through them
–To reduce any electromagnetic interference, connect the power cables as far away as possible from the signal cables
and connect to a RS-485 MODBUS network using a twisted pair
–If using an electrical or pneumatic screwdriver, adjust the tightening torque
–If the device is moved from a cold to a warm place, humidity may cause condensation to form inside; wait for about an
hour before switching on the power
–Make sure that the supply voltage, electrical frequency and power are within the set limits
–Disconnect the power supply before carrying out any type of maintenance
–Do not use the device as a safety device
–For repairs and further information, contact the EVCO sales network; returned goods without the data label will not be
accepted
