1.- IMPORTANT SAFETY CONSIDERATIONS  
SAFETY CONSIDERATIONS  
INSTALLATION  
PRESCRIPTIONS.-  
PRECAUTIONS.-  
Before starting any operation of adjustment, replacement,  
maintenance or repair, the unit must be disconnected from any kind  
of power supply.  
Keep the unit clean , to assure good functioning and performance.  
Use for it a clean and humid rag. Do not use for the frontal lens  
abrasive products, solvents, alcohol, etc... because its transparence  
could be damaged and this may cause difficulty for a correct vision  
of the reading.  
The installation and  
the future use of this  
unit must be done by  
suitable qualified per-  
sonnel. The unit has  
not  
AC  
(mains)  
switch, it will be in op-  
eration as soon as  
power is connected.  
To prevent electrical or fire hazard, do not expose the unit to  
excessive moisture.  
The installation must incorporate an external main switch.  
The unit has a protection fuse incorporated on the AC socket, if it  
is necessary to change or replace, use the time-lag fuse according  
IEC 127/2 and the values indicated below.  
Do not operate the unit  
inthepresenceofflam-  
mable gases or fumes,  
such as environment  
constitutes a definite  
safety hazard. The unit  
is designed to be  
200 mA when the unit is operating at 230 Vac  
400 mA when the unit is operating at 115 Vac.  
mounted in a metal  
panel.  
Install 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. See paragraph 8, WIRING.  
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.  
SAFETY PRESCRIPTIONS.-  
The 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  
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.  
power is applied to the unit. Make signal  
connections before power is applied  
and, if reconnection is required, discon-  
nect the AC (mains) power before such  
wiring is attempted.  
Install the unit in places with a good  
ventilation to avoid the excessive heat-  
ing. 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.  
WARNING : In closed areas do not use systems with  
vaporized liquids.  
POWER SUPPLY.-  
The power supply must be connected to the adequate terminals (see  
the connection instructions). The characteristics of the power supply  
areshowedonthelabelontherearpart. Pleasemakesurethattheunit  
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 to circuits which power  
inductive loads.  
CONNECTIONS  
All wiring connections are made using push-in cable connectors.  
There is a separate connector block for power supply and input  
signals. Please make sure that each connector block is connected on  
the adequate place.  
2
The wire cross section recommended for signal inputs is 1 mm and  
2
for power supply 2.5 mm .  
SIGNAL WIRING.-  
PANEL MOUNTING  
Certain considerations must be given when install the signal input and  
control wires. If the wires are longs can act like an antenna and  
introduce the electrical noise to the unit, therefore :  
Verify that the panel cut-out is correctly according to the dimensions  
indicated on page 11 with a minimum depth of 150 mm. (5.9").  
Install the fixation pieces in the lateral guides of the unit by its rear  
part and then turn the screw firmly against the panel, until the unit is  
totally hold on.  
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.  
See paragraph 12 on page 11.  
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.

3.- MAIN FEATURES  
On this paragraph is detailed the main features for every one of the series which are the following :  
Instruments of four digits plus polarity (only minus) to show temperature using the signal generated by sensors  
type RTD (PT-100 (0.00385), model MX) or Thermocouples (models J1,J2, K1,K2, T1,T2, E1,E2, S1,S2, R1,R2  
and L1).  
All instruments of these two series also has circuitry to linearize the sensor signal and the value displayed is  
proportional to the measured temperature in °C or °F for all range corresponding to every sensor.  
See paragraph 9, page 9.  
Serie LDP-124-XX : 4 digits type LED, seven segments, red or green colour with 57 mm (2.3") height and  
minus sign for polarity.  
Serie LDP-144-XX : 4 digits type LED, seven segments, red or green colour with 100 mm (4") height and  
minus sign for polarity.  
The complete reference for each instrument is obtained replacing the XX by the corresponding reference of  
each temperature sensor.  
The common features for all series are the following:  
MECHANICAL.-  
Housed in a rugged extruded aluminium profile housing for panel mounting or free standing.  
Finished in anodized black colour. The frontal lens is mounted with a special rubber profile which  
provides the front part of the unit with an IP-65 protection.  
CONNECTIONS.-  
Connections for Signal Inputs are made using one screw-clamp connector of four terminals located  
on the rear part of the unit.  
The recommended wire cross section for RTD sensors is 1 mm2.  
For thermocouples must be used the compensate wire adequate for each thermocouple.  
Connection for Power Supply uses a push-in cable connector with 2 terminals for power and 1  
terminal for earth.  
The fuse is located in the Power Supply socket, as well as the spare fuse.  
SENSOR BREAK DETECTION.-  
The linearizing circuits for RTD and for thermocouple sensors are provided with an special control to  
detect when the sensor is broken or when the circuit sensor is opened.  
If it occurs then the display starts to flash.  
AUTOMATIC COMPENSATION.-  
The variation resistance of the RTD sensors is in function of the temperature measured. To avoid  
errors due to the lead wire resistance the LDP-1X4-MX uses a 3-wire measurement, which compensates  
the lead wire resistance. However 2-wire sensors can be used. See wiring connections, paragraph 8.3  
page 8.  
The maximum resistance allowable is 10 .  
The thermocouple sensors generate a voltage produced by the junction of two metals with a different  
characteristics. Therefore use the specific compensation wires for each model of thermocouple on  
the measurement circuit to avoid create a new junction which should generate a small signal and it  
should be added to the signal generated by the thermocouple sensor.  
All instruments for thermocouple sensors are provided with a circuitry for Cold-Junction compensa-  
tion.

start the adjust.  
5.- Adjust the Thermocouple simulator to generate the low signal indicated in TABLE-A.  
6.- Display must shows the DISPLAY value indicated in TABLE-A, if not turn the trimmer PT1located  
on the Signal Conditioner (See paragraph 10.2) until display shows te correct value.  
7.- Adjust the Thermocouple simulator to generate the high signal indicated in TABLE-B.  
8.- Display must shows the DISPLAY value, if not turn the trimmer PT2 located on the Signal  
Conditioner (See paragraph 10.2) until obtain the DISPLAY value.
