The TEC-410 limit control is an over temperature protec-
tion or a high limit safety device with a latching output that
removes power in an abnormal condition when the process
temperature is higher than the high limit set point or lower
than the low limit set point.
The unit is powered by 11–26 or 90–250VDC/VAC supply,
voltage incorporates a 3 amp form C relay for limit control,
a universal input which is fully programmable for PT100,
thermocouple types J, K, T, E, B, R, S, N, L, and 0-60mV,
and an option port is available for one of the following
functions: RS-232, RS-485 communication interface and
Retransmission. Alternative output options include SSR
drive and triac. The input signal is digitized by using an 18-
bit Analog to Digital converter. Its fast sampling rate (5
times/second) allows the TEC-410 to control fast processes
such as pressure and flow in addition to temperature.
RS-485 digital communication is available as an additional
option. This option allows the TEC-410 to be integrated
with a supervisory control system. An alarm output is
another option. A variety of alarm functions and alarm
modes can be programmed for a specific application. The
DC power supply output option is used for an external sen-
sor or transmitter. The standard event input option can be
programmed for remote reset or remote lock out signal
input. The limit annunciator option can be used to control
an alarm buzzer.
Three different methods can be used to program the
TEC-410.
1. Use the keys on the front panel to program the unit
manually
2. Use a PC and setup software to program the unit via the
RS-485 port.
3. Use a PC and configuration software to program the
unit via the programming port.
High accuracy, maximum flexibility, fast response, and user
friendly operation are the main features of the TEC-410
high limit controller.

Dangerous voltages capable of causing death are
sometimes present in this instrument. Before instal-
lation or beginning any troubleshooting procedures, the
power to all equipment must be switched off and isolated.
Units suspected of being faulty must be disconnected and
removed to a properly equipped workshop for testing and
repair. Component replacement and internal adjustments
must be made by a qualified maintenance person only.
To minimize the possibility of fire or shock hazards
do not expose this instrument to rain or excessive
moisture.
Do not use this instrument in areas under hazardous
conditions such as excessive shock, vibration, dirt,
moisture, corrosive gases or oil. The ambient temperature
of the area should not exceed the maximum rating specified
in chapter 6.
2–1 Unpacking
Upon receipt of the shipment, remove the unit from the car-
ton and inspect the unit for any shipping damage.
If there is any damage due to transit, report it and file a
claim with the carrier. Write down the model number, seri-
al number and date code. for future reference when corre-
sponding with our Service Department. The serial number
(SN) and date code (D/C) are labeled on the box and the
housing of the unit.
2–2 Mounting
Make the panel cutout according to the dimensions shown
in figure 2.1.
Remove the mounting clamps and screws and insert the
controller into the panel cutout. Reinstall the mounting
clamp and screws. Gently tighten the screws until the front
panel fits snugly in the cutout.

2–3 Wiring Precautions
•Before wiring, verify the correct model number and
options on the label. Switch off the power while checking.
•Care must be taken to ensure that the maximum voltage rating
specified on the label is not exceeded.
•It is recommended that the power for these units be protected
by fuses or circuit breakers rated at the minimum value pos-
sible.
•All units should be installed inside a suitably grounded metal
enclosure to prevent live parts from being accessible to
human hands and metal tools.
•All wiring must conform to appropriate standards of good
practice and local codes and regulations. Wiring must be
suitable for the voltage, current, and temperature rating of
the system.
•Beware not to over-tighten the terminal screws. The torque
should not exceed 1N-m (8.9 lb-in or 10 KgF-cm)
•Unused control terminals should not be used as jumper
points as they may be internally connected, causing damage
to the unit.
•Verify that the ratings of the output devices and the inputs as
specified in chapter 6 are not exceeded.
•Except the thermocouple wiring, all wiring should use
stranded copper conductor with maximum gauge of 18
AWG.

Notes: 50°C max. air ambient

ASTM thermocouples (USA), the red colored lead

2–4 Power Wiring
The controller is designed to operate at
11–26VAC/VDC to 90–250VAC. Check that the
installation voltage corresponds to the power rating
indicated on the product label before connecting
power to the controller. Near the controller a fuse
and a switch rated at 2A/250VAC should be
equipped as shown in Figure 2-4.
This equipment is designed for installation in an
enclosure which provides adequate protection against
electric shock. The enclosure must be connected to
earth ground.
Local requirements regarding electrical installation should
be rigidly observed. Consideration should be given to pre-
vent unauthorized personnel from accessing the power ter-
minals.
2–5 Sensor Installation Guidelines
Proper sensor installation can eliminate many problems in a
control system. The probe should be placed so that it can
detect any temperature change with minimal thermal lag. In
a process that requires fairly constant heat output, the probe
should be placed close to the heater. In a process where the
heat demand is variable, the probe should be close to the
work area. Some experimentation with probe location is
often required to find the optimum position.
In a liquid process, the addition of agitation will help to
eliminate thermal lag. Since the thermocouple is basically a
point measuring device, placing more than one thermocou-
ple in parallel will provide an average temperature readout
and produce better results in most air heated processes.
Proper sensor type is also a very important factor in obtain-
ing precise measurements. The sensor must have the correct
temperature range to meet the process requirements. In spe-
cial processes, the sensor might have requirements such as
leak-proof, anti-vibration, antiseptic, etc.
Standard sensor limits of error are ±4°F (±2°C) or 0.75% of
the sensed temperature (half that for special limits of error)
plus drift caused by improper protection or an over-temper-
ature occurrence. This error is far greater than controller
error and cannot be corrected on the sensor except by prop-
er selection and replacement.

2–6 Thermocouple Input Wiring
Thermocouple input connections are shown in figure 2-5.
The correct type of thermocouple extension lead-wire or
compensating cable must be used for the entire distance
between the unit and the thermocouple, ensuring that the
correct polarity is observed throughout. Junction/terminal
blocks or splices in the cable run should be avoided, if pos-
sible.
If the length of the thermocouple plus the extension wire is
too long, it may affect the temperature measurement. A 400
ohms K type or a 500 ohms J type thermocouple lead resist-
ance will produce approximately 1°C temperature error.

2-7 RTD Input Wiring
The RTD connections are shown in figure 2-6,
with the compensating lead connected to terminal
19. For two-wire RTD inputs, terminals 19 and 20
should be jumpered. A three-wire RTD offers the
capability of lead resistance compensation, pro-
vided that the three leads are of same gauge and
equal length.
Two-wire RTD should be avoided, if possible, for
the purpose of accuracy. A 0.4 ohm lead resistance
of a two-wire RTD will produce 1°C temperature
error.

Example: A 4-20 mA current loop pressure transducer with
range 0-15 kg/cm2 isconnected to input, then perform the
following setup:
INPT = 4-20 mA IN.LO = 0.00
UNIT = PU IN.HI = 15.00
RESO = 1-DP
Of course, you may select other value for RESO to alter
the resolution.
3–1 Process Input
Press for 4 seconds and release to enter the setup menu.
Press to select parameter. The display will indicate the
parameter symbol and the value (or selection) for that
parameter.
INPT: Selects the sensor type and signal type for the
process input.
UNIT: Selects the process unit
RESO: Selects the location of the decimal point
(Resolution) for most (not all) process related
parameters.
IN.LO: Selects the low scale value for the linear type
input.
Hidden if: T/C or RTD type is selected for INPT
IN.HI: Selects the high scale value for the linear type
input.
Hidden if: T/C or RTD type is selected for INPT
How to use IN.LO and IN.HI:
If 4–20mA is selected for INPT, SL specifies the input sig-
nal low (i.e., 4mA), SH specifies the input signal high (i.e.,
20mA), S specifies the current input signal value, and the
conversion curve of the process value is shown as follows:
OUT1: Selects the output 1 function. The available output 1 functions are: High Limit Control, Low
Limit Control, and High/Low Limit Control. Refer to section 1-6 for limit control operation.
O1.HY: Output 1 hysteresis value. The hysteresis value is adjusted to a value to eliminate relay jitter
in a noisy environment.

LSP.H : Upper limit of LSP1. Hidden if HI is selected for OUT1
HSP.L and HSP.H in the setup menu are used limit the adjustment range of HSP1. LSP.L and LSP.H
are used to limit the adjustment range of LSP1.

3–4 PV Shift
In certain applications it is desirable to shift the controller display value (PV) from its actual value.
This can be easily accomplished with this control by using the PV shift function.
Cycle the unit to the SHIF parameter by using the scroll key in setup menu. The number you adjust,
either positive or negative, will be added to the actual value. The SHIF function will alter the
process variable (PV) only.

3–5 Digital Filter
In certain applications the process value is too unstable to be read. To improve this, a programmable
low pass filter is incorporated in the TEC-410. This is a first order filter with the time constant speci-
fied by the FILT parameter which is found in the setup menu. The default value of SHIF is set at 0.5
seconds before the unit is shipped. Adjust FILT to change the time constant from 0 to 60 seconds. 0
seconds means no filter is applied to the input signal. The filter is characterized by Figure 3-2 below.
