NOTE .- The current loop generated by
the CCT is ACTIVE. The CCT powers
the current loop. Do NOT connect the
output loop to elements which are also
active. This will damage both elements.
5.- OUTPUT SIGNAL .- SELECTION AND CONNECTIONS

13.- WARRANTY
FEMA ELECTRÓNICA, S.A. warrants this product free of defects in workmanship for ONE (1) year from the date of shipment. This Warranty
is VOID if the unit shows evidence of damages as a result of misapplication, accident, misuse or if the product had been tampered or repaired
by personnel or companies without the official authorization of FEMA ELECTRÓNICA, S.A. This Warranty is VOID also for damages caused by
defective or inappropriate applications. In case of malfunction return the unit to the manufacturer for evaluation. Within the warranty period, and
after examination, and if the unit is found to be deffective and covered by this warranty, the unit will be repaired or replaced.
LIMITATION OF LIABILITY : FEMA ELECTRÓNICA, S.A. shall not be responsible for any damage or loss to other equipment however caused,
which may be experienced as a result of the installation or use of this product. The liability shall not exceed the purchase price paid of the product
upon which liability is based. In no event shall FEMA ELECTRÓNICA, S.A. be liable for consequential, incidental or special damages.

EXCITATION VOLTAGE.- The model CCT-32 supply the Excitation voltage for
sensors, through the terminals 3 & 5. Do not connect these terminals to other
external power supply, permanent damages may result to the unit.
SIGNAL WIRING.- Certain considerations must be given when install the signal
input wires. If the wires are longs can act like an antenna and introduce the
electrical noise to the unit, therefore: Do not install the signal input wires in the
same conduit with power lines, heaters, solenoids, SCR controls etc...and
always far from these elements. When shielded wires are used, leave
unconnected the shield on the transmitter side and connect the other end of the
shield to the ground terminal of the machine.
SAFETYCONSIDERATIONS
PRESCRIPTIONS.- Before starting any operation of adjustment, replace-
ment, maintenance or repair, the unit must be disconnected from any kind of
powersupply.Keeptheunit clean , toassure goodfunctioning andperformance.
Topreventelectrical or fire hazard,donot expose theunitto excessive moisture.
Do not operate the unit in the presence of flammable gases
or fumes, such an environment constitutes a definite safety
hazard.Theunit is designedto be mounted ina 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 systems with vaporized liquids.
11.- PRELIMINARY NOTES
INSTALLATION.-PRECAUTIONS
Theinstallation and useof this unitmust be doneby qualified
personnel. The unit has not AC (mains) switch, neither
internal protection fuse. it will be in operation as soon as
powerisconnected.Theinstallationmustincorporateanexternalmainsswitch
with a protection fuse in the power line
Power : 230 Vac Fuse 50 mA
Power : 115 Vac Fuse 100 mA
Power : 24 Vdc Fuse 300 mA
Add the appropriate devices to the installation in order to protect the operator
and system when using the unit to control a machine or process where injury
to personnel or damage to equipment may occur as a result of failure of the
unit. SAFETY PRESCRIPTIONS.- This unit has been designed and
tested under EN-61010-1 rules and is delivered in good condition.
This operator's manual contains useful information for electrical
connections. Do not make wiring signal changes or connections
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 a 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 characteristics of the power
supplyareshowedontheside label. Please makesurethattheunitis 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
whichpowerloads in cycle ON-OFForto circuits whichpowerinductive loads.
WARNING.- If the power supply is dc voltage, be careful with the polarity
indicated for each terminal.
