Warning!
Failure of devices such as the thermocouple/RTD sensor, heater output relay or temperature control may result in
severe damage to a product while in process, melting of the heater or a damaging fire. A latching over-temperature
protection device such as a Tempco model TEC-910 or TEC-410 high-limit controller with manual reset must be
installed in your process. This device should remove power to the heating circuit if the above failure occurs. We
recommend this device be classified as a safety control and carry FM, U.L/CSA Listing or certification. Failure to
install high-limit protection where a potential hazard exists could result in damage to equipment, property and possible
severe injury to personnel.

1 Introduction
1.1 Introduction
The new generation of Tempco PID microprocessor-based Fuzzy logic controller series
incorporates two bright and easy to read LCD Displays which indicate Process Value (PV) and Set point (SP).
The Fuzzy Logic technology incorporated on these series controllers enables a process to reach a
predetermined set point in the shortest time with minimum of overshoot during start up (Power ON) or
external load disturbances (example: an oven door being opened).
Different controller models in this series are as follows:

These controllers are powered by an 11-26 or 90-250 VDC/VAC supply, incorporating a 2 Amp control relay output as
a standard. The second output can be used as a cooling control or an alarm. Both outputs can be selected as a 5VDC
or 14VDC logic output, linear current or linear voltage to drive an external device. There are six types of alarms and a
dwell timer that can be configured for the third output. The controllers are fully programmable for Linear current,
Linear Voltage, PT100 and thermocouple types J, K, T, E, B, R, S, N, L, U, P, C, and D. The input signal is
digitized by using an 18-bit A to D converter. Its fast sampling rate allows the controller to control fast processes.

Press and hold key 5 seconds to activate Auto-Tuning Mode
Note:
§ Using Manual, Auto-Tuning, Calibration modes will break the control loop and change some of the
previous setting data. Make sure that the system is allowable to apply these modes.
§ The flow chart shows a complete list of all parameters. For actual application, the number of
available parameters will vary depending on the setup and model of controller, and will be less
than that shown in the flow chart.
§ The user can select up to 8 parameters to put in the user select menu by using the SEL1~SEL8
parameters in the setup menu.

2 Installation and Wiring
Sometimes dangerous voltages capable of causing death are present in this instrument. Before
beginning installation or any troubleshooting procedures, power to the 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 qualified
maintenance personnel 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 the specifications section.
Remove stains from this equipment using a soft, dry cloth. Do not use harsh chemicals, volatile solvents
such as thinner or strong detergents to clean the equipment in order to avoid deformation.
2.1 Unpacking
Upon receipt of the shipment, remove the controller from the carton and inspect the unit for shipping damage.
If any damage is found, contact your local representative immediately. Note the model number and serial
number for future reference when corresponding with our service center. The serial number (S/N) is labeled
on the box and the housing of the controller.
The controller is designed for indoor use only, and is not intended for use in any hazardous area. It should be
kept away from shock, vibration, and electromagnetic fields (such as variable frequency drives), motors and
transformers. It is intended to operate under the following environmental conditions.
Environmental Parameter
Specification
Operating Temperature
14°F to 122°F (-10°C to 50°C)
Humidity

2.2 Mounting
Make the panel cut out per the dimensions required by the controller. The dimensions of the different sizes of
this series controller series are given in the following section. Remove the mounting clamps from the controller
and insert the controller into the panel cut out. After inserting the controller into the panel cut out, re-install the
mounting clamps. Gently tighten the clamp screws until the controller is properly secured into the cutout.
2.3 Wiring
Sometimes dangerous voltages capable of causing death are present in this instrument. Before doing
installation or any troubleshooting procedures, the power to the 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.
The utmost care must be taken to ensure that the maximum voltage rating specified on the label is not
exceeded.
It is recommended that the supply power of these units be protected by fuses or circuit breakers rated at the
lowest value possible.
All units should be installed inside a suitably grounded metal enclosure to prevent live parts 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.
The tightening torque on the Screw terminals should not exceed 1 N-m (8.9 Lb-in or 10.2 Kg F-cm).
Except Thermocouple Wiring, all other wires used are to be standard copper conductors with the maximum
Gauge not exceeding 18AWG.
