Cut a hole in the panel. (See the figure for overall dimensions.)

Slide the controller into the cutout from the front of the panel.

Fit the mounting clamps to the controller, ensuring the lugs are located in their slots.

Fasten the mounting clamps using the retaining screws.

The cables used for powering the controller and the power outputs must conform to the standarts IEC 60245 and IEC 60227.

To minimize the pick-up of electrical noise, the wiring of low voltage lines, particularly the sensor input should be routed away from the high-current power cables. Where it is not possible, use shielded cables with the shield grounded at both ends.

E-70-Ö controller does not include a power switch. Therefore, the power supply to the controller and power outputs must be wired through the proper fuse or circuit breaker.

E-70-Ö controller should be installed inside a suitable grounded metal enclosure (panel). This must prevent the live parts being accessible to human hands and metal tools.

E-70-Ö digital controller measures its input temperature by means of a Pt-100 resistance thermometer and controls two output relays as a function of the input temperature and the state of internal timers. The control of RL1 and RL2 output relays are as follows;

RL1: When the device is energized, the output relay RL1 is activated. When the measured temperature decreases and becomes equal to SETL (2°C), 10 minutes timing will be started. During the timing period, RL1 will be active and measured temperature has no effect on the state of RL1. When the time is out, RL1 becomes inactive, provided that the measured temperature is less than SETH (10°C). When the temperature increases and reaches SETH, RL1 becomes active again and the same steps will be repeated. The state of RL1 is indicated by the green led ECO, this led is illuminated while RL1 is inactive.

RL2: Applying the operating voltage to the controller starts 20 minute timer. Initially the output relay RL2 is de-energized. During the timing period, RL2 will be inactive and measured temperature has no effect on the state of RL2. When timing expires, the state of RL2 is controlled by the input temperature. When the temperature is between ASTL (0°C) and ASTH (15°C), RL2 will be inactive. If the measured temperature is greater than ASTH or less than ASTL, RL2 will be energized. ALM led (red) on the front panel will be flashed while RL2 is energized.

E-70-Ö is housed in a 72 x 72 mm plastic case conforming IEC 668 standard. The operating voltage of the device is 24 V AC ±%10, 50-60 Hz.

5. CONNECTION DIAGRAM

Before operating the controller, ensure that the controller is correctly configured. Incorrect configuration could result in damage to the process being controlled.

The terminals 01 to 07 are electrically live. While the instrument is powered, never touch to these terminals.

The labels on the sides of the controller identify the ordering code (Type), serial number and wiring connections.

Connection diagram is given below.

The front panel view of the E-70-Ö controller is given in section. In normal operation, the four digit display displays the process value and unit. The display of the controller displays between -19 and 99. Out of this range or while the connection of the sensor is broken the display will be shown as ( )

6. OPERATION

The other parameters are configured in configuration mode.

In order to access the configuration mode, and buttons must be pressed simultaneously.

Just after this operation, message is displayed for one second duration, is displayed in the display. The security code must be entered with and buttons in order to access the parameters.

COD

The entered security code must be correct, otherwise pressing button will revert to normal operation.

The factory setting value of security code is “10”. The security code is defined by parameter; user can edit this parameter to define a new security code. If the value of security code is forgotten, pressing and

buttons simultaneously at least 10 seconds, makes possible to access

the parameters.

PAS

If the entered security code is correct, pressing key will select the first parameter.

While a parameter is selected, the parameter value is edited by and

buttons. Pressing button will select the next parameter. Pressing button exist the configuration mode.
