Page 3: Introduction
Introduction The TR-EVO temperature controller is a valid tool to adjust temperature in heating elements, without using external sensors. By taking advantage of the voltage-current characteristic, the TR-EVO manages to maintain the temperature set even in conditions of high heath loss, thereby obtaining considerable benefits compared to traditional methods used. -

Page 7: Description Of The Connections On The Power Unit
The cables are used for connection to the power unit and the RS485 communication module of the PLC. Wire the system using the adequate wiring diagrams for your configuration. For example, a minimal diagram is provided below. TR-EVO 8.8.8 ≡... - Page 8 A 16A fuse with semi-rapid response should be used as the protective component. Terminals 3, 4 Output to pulse transformer primary. The transformer should be dimensioned starting with the size of the element to control, i.e. the type of alloy, width, thickness and length. (see specific section).
- Page 9 Terminals 9, 10 "IN WORK" output Opto-isolated output of sealing circuit signaling: this optical coupler is closed during the sealing cycle, and return open at the end of the cycle; see the "operating modes" section for further operating details. It can be externally configured NPN or PNP, with a maximum current which must not exceed 50mA at 24 Volts continuously.

Page 10: Signalling On Power Module
Current measurement input To sense the heating element current, TR-EVO has a dedicated passage where to pass one of the connecting cables between transformer and heating element. Normally the cable only makes one passage through the hole. -

Page 12: Hardware" Configuration
The formula: Pr=Cs×Lu× LaSp×2 enables calculation of the maximum power Pr required by the heating element, where: Cs = surface load in Watts per cm . This value determines the speed the bar heats and assumes, as seen above, a reference value of 30. Naturally, this value can be changed if higher speed is required, or less power supply is available, or power that exceeds the maximum that can be supplied by the controller. -
Page 13: Start-Up
Start-up On first start-up, the equipment will probably give an error signal. This signal is normal and depends on the fact the parameters of the heating element have not been registered yet. For the temperature controller to acquire these parameters, the Tuning procedure must be activated which should always be executed after replacing the heating element. -

Timed: temperature in this mode, when the pre-heating input is on, it activates temperature adjustment to the pre-heating temperature. Start input activates the timed heating cycle which is composed of 2 phases. The first phase (indicated with the TD led on the display) delays heating starting for the time set on the relevant timer. - Page 16 Rapid temperature change This error occurs in the tuning procedure and highlights the operation started with the heating element hot. Wait for it to cool and repeat the operation. Insufficient voltage reading; this error occurs in the tuning procedure and highlights an error in transformer connection or in its dimensioning.

Short circuit: - on the secondary circuit of the pulse transformer. - on the heating element. - on the twisted cable. Heating activated in error; this error indicates a likely fault in the power adjustment element. It can activate in the event of high inductive pulses on the power supply.
