temperature contoller ELTC-MV2
BU 123
Revision 1
Ramp mode with continuous output
The actual value x is recorded via a temperature sensor or a
standard signal and converted into a digital signal. Before this
signal is sent to the controller, the actual value is corrected.
The corrected actual value is shown on the display.
The setpoints w1 to w9 and the associated running times t1
to t9 are set on the controller. The current ramp phase, the
current setpoint and the remaining run time of the ramp
section can be shown on the display.
The size of the output signal can be limited by a minimum
and maximum value on the controller.
The hysteresis h is set on the controller. When controlling with
a continuous output, the hysteresis indicates the range in
which the output signal varies between 0/4mA and 20mA or
0/2V and 10V.
The control difference x
di
= w
i
- x is formed with the current
setpoint in the controller.
If the control difference is x
di
< h, he output emits a signal up
to 20mA or 10V.
If the control difference is x
di
≥ h, he output emits a signal of
20mA or 10V.
If the actual value is above the set setpoint w, the output
emits a signal of 0/4mA or 0/2V.
