E-48 series universal process controllers are advanced new generation
microcontroller based industrial instruments designed for On/Off and PID
control forms, dimensions of 48x48 mm compatible with IEC/TR 60668
standarts. Universal inputs and outputs of controller can be programmed
easily by the user.
E-48 process controllers are equipment having high reading sensivity and
capability, with no moving parts, having infinite life and very low calibration
drift with time and environment conditions. Indicating method is 2x4 digit LED
display. E-48 indicating range is from -1999 to 9999 and is able to connect
mV, mA, thermocouple, resistance thermometer and other sensors and
transmitters. Controllers have high input empedance and protecting and
warning the system against the breakage sensors.
E-48 process controllers can be used in every field of the industry for the
measurement and control of temperature, pressure, level, speed, current,
voltage, resistance and other physical units; as well asin the industry
branches of iron&steel, cement, plastic, chemistry, metallurgy, petrochemical
refineries, ceramic, glass and others.
E-48 controller is designed for panel mounting and
should be used in an industrial environment.

The labels on the sides of the controller identify the ordering code
(Type), serial number and wiring connections.
The controller options are also indicated on the wiring diagram.

The terminals 01 to 05 are electrically live. While the
instrument is powered, never touch to these terminals.
 Before operating the controller, ensure that the
controller is correctly configured. Incorrect
configuration could result in damage to the
process being controlled.

 E-48 controller should be installed inside a suitable
grounded metal enclosure (panel). This must
prevent the live parts being accessibleto human
hands and metal tools.

E-48 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.

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.
 The cables used for powering the controller and the power
outputs must conform to the standarts IEC 60245 and IEC 60227.

AUTO-TUNE

 Auto-tuning matches the characteristics of the controller to the
process being controlled in order to obtain good control. Tuning
involves calculating and setting the values of the PID parameters.
The Auto-tuner works by switching the output on and off to induce an
oscillation in the process value. From the amplitude and period of
oscillations PID parameters are calculated.

Auto-tune can be performed at any time, but normally it is performed
only once during the initial commissioning of the process. However,
if the process under control subsequently becomes unstable
(because its characteristics have changed), you can re-tune again
for the new conditions.
 In order to start Auto-tune process:
1- Set the CNTL parameter in OCNF page as PID.
2- Set the control set point to the value at which you will normally
operate the process. Consider also the process value may exceed
the control set point while in Auto-tuning.
3- Set the HYS parameter in TUNE page as 0. 1 (if DP=1) or 1 (if DP=0).
4- Set the AT parameter in TUNE page as ON to commence
Auto-tuning process. Press  button to revert the normal operation.

The lower display and SF led will flash to indicate that tuning is in
progress.

After a few cycles of oscillation the tuning is completed and the
calculated PID parameters PB, IT and DT are stored.
 While the Auto-tuning in progress if AT parameter is set the OFF or
operating power of the controller is interrupted Auto-tune progress is
stopped and old PID values are retained.
