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.
m
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.
m
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.
m
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.
