4. INSTALLATION
4.1. PLACING THE EQUIPMENT
The equipment is provided in a hermetically
sealed box (IP 65) with a transparent front cover and
an opaque cover for the connection housing.
For the wall-mounting of the unit, there are two
holed pieces in the upper corners. There are also two
more holes in the inside of the connection housing.
Fix the unit with screws on a wall or similar, so
that the screen is in your field of vision.
Avoid proximity to:
-
High voltage devices.
-
Transformers.
-
Motors or sources of vibration.
Or any other source of interference which
-
coud affect the correct working of the unit.
Also avoid temperatures in excess of 50ºC,
-
condensation, drips, vibrations, etc.
To maintain the isolation of the unit, it is
essential to keep the transparent and opaque panels
closed.
4.2. CONNECTION
To connect the unit, remove the lower cover to
reach the terminals.
For the cable entries, it is necessary to remove
the relevant dies (this should be done with the
connection cover in place and screwed to avoid
possible breakage).
It is advisable to install the stuffing box
(prensaestopas) in the open dies, which are included
with the unit.
It is advisable to connect the cables to the
terminals with terminal connection, which are also
included with the unit.
4.3. SUPPLY TO THE EQUIPMENT
The power supply should be at 220 V. AC. It is
recommendable to do this as directly as possible from
the general switch, avoiding that the same cable
supplies command lines, relays, switchers, etc.
Do not use the same line which supplies the unit
to supply the outlets of relays.
For unestable or fluctuating voltages, use grid
stabilizers.
It is important to connect the earth terminal, to
discharge the perturbations which there could be in the
supply.
If the equipment is placed on an electric
switchboard, the earth terminals of the equipment
should be joined in star, at the same point of the
switchboared and from this one to the earth terminal
bar with a section equal to the supply cables of the
switchboard.
The equipment is protected in the supply by a
varistor between the phase and t h e neutral which will
short circuit the fuse on detecting an overload on the
line, and the two supply lines are filtered towards the
earth terminal.
Do not increase the value of the fuse (0.4 A) as
this would suppose the destruction of components. On
the backside of the cover for the connection housing
there are some spare fuses stuck.
Group of three grid supply terminals to the
equipment (right side).
TERMINAL 1: Input of phase of 220 V ac,
protected by the fuse.
TERMINAL 2: Input of neutral of 220 V.
TERMINAL 3: Input of earth terminal
4.4. INPUTS
TERMINAL 1.- Digital input number 1.
TERMINAL 2.- Digital input number 2.
Those two inputs are optojoined to protect the
circuits; the input will be activated when we join them,
with a contact, to terminal number 6.
The contacts of the connection systems which
are connected here must be normally open and free of
tension.
TERMINALS 7 TO 14: Inputs of sensors from
number 1 to number 8.
The inputs of sensors are prepared in the
factory to adapt them to the different values of tension
or power that every sensor can have.
An input without modification has a level of 0 to
5 V. (If those limits are overcome, it can cause
breakage to the system).
TERMINAL 15: Analogical internal earth (it is not
used).
TERMINAL 16: Supply of sensors. Earth at 0 V.
TERMINAL 17: Supply of sensors. 17 V positive
stabilizing.
TERMINAL 18: Supply of sensors.18 V negative
without stabilizing.
NOTES: Make sure that the cables from the
inputs of sensors and digitals are installed away from
the lines of tension of the installation.
Make sure that the cables are screened and the
casing is connected to the earth of the equipment.
4.5. OUTLETS
TERMINAL 3:Analogical outlet of 0 to 10 V, nº 3.
TERMINAL 4:Analogical outlet of 0 to 10 V, nº 2.
TERMINAL 5:Analogical outlet of 0 to 10 V, nº 1.
TERMINAL 6:General of analogical outlets.
Avoid to shortcircuit an analogical outlet with the
general of analogical outlets.
TERMINAL 16:Outlet supply sensors - Earth to
0v.
