RAMP MODE
Ramp start
Press button „ “ for >5 seconds, LED „2“ lights up continuous-
ly.
If the actual value is below the value stored for P50 (= start
value), this value (P50) is initially heated up (in two-point con-
trol). After reaching the start value, the stored ramp function
(P51 to P68) is started.
If the actual value is abovw the start value stored for P50, the
stored ramp function starts immediately.
After reaching the lsat stored ram value, LED "2" goes out and
the set temperature setpoint "P10" is approached (in two-po-
int control) and maintained permanently.
Pause
Press button „ “ for >5 seconds, LED „2“ flashes at a regular
rate. Current temperature is maintained permanently. By pres-
sing the button „ “ again for >5 seconds the ramp continues.
Abort the ramp in a controlled manner
Press button „ “ and „ “ simultaneously for >5 seconds, LED
„2“ flashes alternately long / short. Starting from the current
temperature, the ramp is ramped down with the next smaller
ramp value. After reaching the smallest ramp value, LED "2"
goes out. The set temperature setpoint "P10" is then appro-
ached and maintained permanently.
Cancel ram immediately
Press button „ “ and „ “ simultaneously for >5 seconds, LED
„2“ flashes alternately long / short. Press button „ “ and „ “
simultaneously again for >5 seconds, LED „2“ goes out.
The ramp function is now inactive, the set temperature setpo-
int "P10" is then approached and maintained permanently.
Ramp mode 2-point
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.
A hysteresis h can be set on the controller.
In the controller, the control difference is formed with the
current setpoint x
di
= (w
i
- h) - x
