Dispose according to the standards for electrical
and electronic equipment RAAE
Installation Rules Notes and Warnings
 Protect the device from direct exposure to sunlight.
 Do not position the device near or directly in contact with sources of heat
or electromagnetic fields.
 Fix the device of a height of at least 60 cm from the ground.
In a clearly visible place easily accessible.
 Connect the device to power lines other than those for operating motors or other
large power devices which could generate network interference or instability.
 The electrical supply of the unit must be protected by a differential switch
2 0Vac~ 0mA and a bipolar magneto thermic 2 0Vac~ 10A, positioned in a
place easily accessible.
 Before working on the equipment to perform any operation switch off the
magneto thermic differential switch.
 For electric operations, always remove voltage, wait 0 seconds for the
inside capacitors to discharge before opening. At the end of the
operations, close the device to restore the correct degree of protection before
powering up.
 For the connection of the supply voltage, use anti-flame wires with a minimum
section of 0.75mm² certified and conform to the standard IEC60227 or IEC60245.
 Use flame-retardant cables with a minimum cross-section area of 0.75 mm² for all
control signals.
 Use flame-retardant cables with a minimum cross-section area of 0.75 mm² to
connect to the indicating relays.
 Use flame-retardant cables with a minimum cross-section area of 0.5 mm² for
electro valves control signals.
 The wire ground conductor of protection must be yellow/green.
 The wire ground conductor of protection must be connected first.
 The wire which is colored yellow/green must only be used for the ground
conductor.

 The cable glands must be chosen according to the diameter of the cable to be
used.
 The sealing of the press cable is guaranteed by the compression of the rubber
gasket that tightens on the outer diameter of the cable.
 The tightness of the cable gland is guaranteed by the compression of the rubber
seal that tightens on the outer diameter of the cable.
 The size of cable and cable gland must ensure that a power cord traction is not
acting on the terminals.
 The terminal block must not be the point of mechanical anchoring of the
conductors.
 The cable gland PG9 supplied on request, has cable diameter minimum of 4mm
and a maximum of 8mm, with clamping nut by 19mm.
 Any use not described in this user instruction manual or incorrect use of the
device may cause damage to the device or to the devices connected to it.
 Furthermore, incorrect use or tampering with the device may cause injury.
 Waterproofness of the casing is guaranteed when the flap is closed.
 Make sure that rigid or flexible ducts used for wiring, if any, do not fill up with
water or other liquids.
 Do not make holes not protected on the container or protected by accessories with
protection degree lower than that of the housing of the control unit.
 Cut off power supply immediately if water is found in the casing.
 If the control unit is used in ways not specified by the manufacturer, the
protection provided by the device may be impaired.
 The E7T Control Unit does not release potentially toxic or harmful substances to
the health and the environment.
 No part with dangerous voltage is normally accessible.
Do not use the control unit if you have not read or do not understand this manual.

lectrical Connections
To connect the wires to the E7T control unit, remove
the cover panel to access the terminal board,
unscrewing the two screws.
If the economiser is in G2 version with reinforced transformer, connect two solenoid valves in
parallel to each terminal.

Keyboard And Monitor
There are 5 round keys on the front panel to control the intrument and select
functions.
At power on, during the verification of initialization,
the first screen that is shown is the firmware
version.
The next screen is always displayed during normal
operations:
 Menu
provides access to settings it is used as RESET
in the event of alarms
 Keys
Increase and decrease the values, manually start valves in Test mode, used to
scroll any alarms.
 The S key allows to start / stop the activation of the solenoid valves.
 Use the L key to select one of the 5 available languages: Italian, English, French,
German, Spanish.
On the main screen, when an alarm is active, the letter L changes state becomes A ,
pressing scrolls through the alarms, pressing A returns to the screen with
the operating mode.
In the versions with tribo electric probe, the black box between the two
keys indicates that the probe is installed.
With the probe installed the – key changes the screen to display the readings of the
emissions.
Without the probe installed is available only the screen with the operating mode.
