Configuration  
To set-up the Limitrol only 3 steps are required:  
1. Wire the instrument (page 7).  
2. Configure the instrument (page 14).  
3. Check the operating parameters (page 22).

USE WIRE SUITABLE  
FOR 75°C MINIMUM.  
NOTES  
For supply connections use No 16 AWG or larger  
wires rated for at least 75 °C.  
Use copper conductors only.  
Class 2 wiring must be a minimum of 1/4 inch from  
any Class 1 conductors.

MOUNTING REQUIREMENTS  
Panel surface texture must be better than 6.3 µmm.  
Select a mounting location with the following  
characteristics:  
1) Minimal vibration.  
2) An ambient temperature range between 0 and  
50°C (32 and 122 °F).  
The instrument is shipped with a rubber panel gasket (50  
to 60 Sh). To assure the IP65 and NEMA 4 protection,  
insert the panel gasket between the instrument and the  
panel as shown below.  
3) Easy access to the rear of the instrument.  
4) No corrosive gases (sulfuric gas, ammonia, etc.).  
5) No water or other fluid (i.e. condensation).  
6) Relative humidity of 20% to 80% non condensing.  
Install the instrument as follows:  
1) Insert the instrument in the gasket.  
2) Insert the instrument in the panel cutout.  
3) Pushing the instrument against the panel, insert the  
mounting bracket.  
4) Torque the mounting bracket screws between 0.3  
and 0.4 Nm (2.66 and 3.54 lbf-in).  
The instrument can be mounted on a panel up to 15 mm  
(0.591 in) thick with a square cutout of 45 x 45 mm (1.772  
x 1.772 in). For outline refer to Dimensions and Panel  
Cutout.  
5) To insure NEMA 4X/IP65 protection, make sure the  
instrument does not move within the cutout .

NOTE:  
NOTE: When a relay output is used to drive an inductive  
load, connect an external snubber network (RC) across  
the terminals:  
1) Do not run input wires with power cables.  
2) For TC wiring use proper compensating cable,  
preferably shielded (see Thermocouple Compen-  
sating Cable Color Codes).

3) Shielded cable should be grounded at one end

4) The resistance of the 3 wires must be the same.  
NOTE:  
1) Do not run input wires with power cables.  
2) High line resistance can cause measurement  
errors.  
3) When shielded cable is used, ground it at one end  
only to avoid ground loop currents.  
4) The input impedance is equal to:  
B) Logic Input  
Less than 5 for 20 mAdc input  
Greater than 1 Mfor 60 mVdc input  
Greater than 400 Kfor 5 Vdc and 10 Vdc input  
This input is used as a remote reset.  
Safety note:  
-
-
Do not run logic input wiring with AC power cables.  
Use an external contact with a contact rating  
greater than 0.5 mA, 5 Vdc.  
-
The instrument needs 100 ms to recognize a  
contact status variation.

When the fuse is damaged the instrument should be  
returned to your supplier to check the power supply.  
7) Safety requirements for permanently connected  
equipment:  
-
Include a switch or circuit-breaker in the  
installation.  
-
Place the switch in close proximity to the  
equipment and within easy reach of the  
operator.  
-
Mark the switch as the disconnecting device for  
the equipment. NOTE: A single switch or  
circuit-breaker can drive more than one  
instrument.  
8) When the NEUTRAL line is present, connect it to  
terminal 4.  
9) To avoid shock and possible instrument damage,  
connect power last.

A sensor break is signaled as "OPEN”. On the mA/V  
input, a sensor break can be detected only when the  
range selected has a zero elevation (4/20 mA, 12/60 mV,

CALIBRATION PROCEDURE  
f) during calibration, connect one input at a time to the  
rear terminal block.  
Calibration parameters are logically divided into groups  
of two parameters each – initial scale value and final  
scalevalue. Acalibrationcheckisprovidedafterentering  
the values of each group. It is also possible to perform a  
calibration check without making an entry: press the  
FUNC button twice when “OFF” is displayed. The instru-  
ment goes directly to the group check.  
g) Use calibrators with the following:  
Accuracy  
TC Input:  
+0.005% output  
+0.001% range  
+5 mV  
RTD Input:  
+0.02%  
+0.0025 decade

CJ Compensation:  
Before beginning calibration, be sure the internal DIP  
switch V101 is open.  
Current Transformer: 0.1 mA AC rms  
Resolution  
TC Input:

WARNING:Performthecalibrationprocedureaccording  
to J106 jumper positions as shown in Figure 1. Other-  
wise, the stored calibration values may be lost.

to air conditioning or other mechanical devices.  
c) Relative humidity should not exceed 70%.  
d) Minimum warm up time of at least 20 minutes.

MAINTENANCE  
1. Remove power from the power supply terminals and  
from relay output terminals.  
2. Remove the instrument from case.  
3. Using a vacuum cleaner or a compressed air jet (max.  
3kg/cm2) remove dust and dirt which may be present  
on the louvers and on the internal circuits, being  
careful to not damage the electronic components.  
4. Clean external plastic or rubber parts only with a cloth  
moistened with ethyl alcohol (pure or denatured)  
[C2H5OH]; or isopropyl alcohol (pure or denatured)  
[(CH3)2CHOH]; or water [H2O]  
5. Verify that there are no loose terminals.  
6. Before re-inserting the instrument in its case, be sure  
it is perfectly dry.  
7. Re-insert the instrument and turn it ON.
