INSTALLATION PRECAUTIONS
.- The installation
and use of this unit must be done by qualified
operators. The unit has not power switch, and
the
unit has not internal protection fuse
, and will start operation as
soon as power is connected. The installation must incorporate an
external main switch with a protection fuse of :
fuse 50 mA (at 230 Vac power)
Also the necessary devices to protect the operator and the process
when using the unit to control a machine or process where injury to
personnel or damage to equipment or process, may occur as a result
of failure of the unit.
SAFETY PRESCRIPTIONS
.- The unit has been designed and
tested under UNE 20553 rules and is delivered in good
condition. This manual contains information for electrical
connections. Do not make wiring signal changes or connec-
tions when power is applied to the unit. Make signal connections
before power is applied and, is reconnection is required, disconnect
the AC (mains) power before such wiring is attempted. Install the unit
in places with a good ventilation to avoid the excessive heating. And
far from electrical noise source or magnetic field generators such as
power relays, electrical motors, speed controls etc... The unit cannot
be installed in open places. Do not use until the installation is finished.
POWER SUPPLY
.- The power supply must be connected to the
adequate terminals (see the connection instructions). The charac-
teristics of the power supply are written on the attached label. Please
make sure that the unit is correctly connected to a power supply of
the correct voltage and frequency. Do not use other power supply
otherwise permanent damage may be caused to the unit. Do not
connect the unit to power sources heavily loaded or to circuits which
power loads in cycle ON-OFF or circuits with power inductive loads.
SIGNAL WIRING
.- Certain considerations must be given when install
the signal input and control wires. Long wires can act like antennas
and introduce electrical noise to the unit, therefore :
A.- Do not install the signal input or control wires in the same
conduit with power lines, heaters, solenoids, SCR controls etc....and
always far from these elements.
B.- When shielded wires are used, connect the shield to the
common terminal and leave unconnected the other end of the shield
and do not connect to the machine ground.
EXCITATION VOLTAGE
.- The unit supplies exci-
tation voltage for sensors, at terminals 3 and 4. Do
not connect these terminals to external power
supply, permanent damages may result to the unit.
SAFETY CONSIDERATIONS
.- Before starting any operation of
adjustment, replacement, maintenance or repair, the unit must be
disconnected from the power supply. Keep the unit clean , to assure
good functioning and performance. To prevent electrical or fire
hazard, do not expose the unit to excessive moisture. Do not operate
the unit in the presence of flammable gases or fumes, such as
environment constitutes a definite safety hazard. The unit is de-
signed to be mounted in a metal panel.
If the unit shows signs of damage, or is not able to show the expected
measures, or has been stored in a bad conditions or a protection
failure can occur, then do not attempt to operate and keep the unit
out of service.
IN CASE OF FIRE
1.- Disconnect the unit from the power supply.
2.- Give the alarm according to the local rules.
3.- Switch off all the air conditioning devices.
4.- Attack the fire with carbonic snow, do not use water in any case.
WARNING : In closed areas do not use sys-
tems with vaporized liquids.
CONNECTIONS
All wiring connections are made using push-in cable connectors.
There is a separate connector block for power supply, input signals
and each relay output. Please make sure that each connector block
is connected on the adequate place.
PANEL MOUNTING
.- The instrument size case is 1/8 DIN. The
internal electronic circuit can be inserted or removed by the front part
and is held on to the case by the two lateral lugs, which must be put
in their corresponding holes placed on each case side. Verify that
the panel cut-out is correctly according to the dimensions indicated
with a minimum depth of 135 mm. (5.31"). Install the fixation clips of
blue colour in the lateral guides of the unit by its rear part and then
slide and press them firmly against the panel, until the unit is totally
hold on.
