6.2. 2-point-controller
This chapter describes device how to adjust the switching values of the device used as a 2-point-controller.
This instruct
ion demands that you selected “
2P
“ as your desired output function like it is explained in chapter 5.1.
- Press button 1
(if not already done).
The device will be displaying “
1.on
“ (turn-on-point of switching function 1).
- Use button 2 or button 3 to set
the desired value, the device‟s switching function 1 should be turning on.
- Press button 1
to validate your selection. The display shows “
1.on
“ again.
- Press button 1
again, the device will be displaying “
1.off
“. (turn-off-point of switching function 1)
- Use button 2 or button 3
to set the desired value, the device‟s switching function 1 should be turning off.
- Press button 1
to validate your selection. The display shows “
1.off
“again.
Example: You want to control the temperature of a heating coil, with a hysteresis of +2°C, to 120°C.
Therefore you will have to select the turn-on-
point “1.on“ to 120°C and the turn-off-point to
“122°C“. When your heating coil temperature falls below 120°C it will be turned on. When the
temperature rises above 122°C the heating coil will be turned off.
Note: Depending on the inertia of your heating coil an overshooting of the temperature may be possible.
- When pressing button 1
again, the display shows “
1.on
“ again.
Now you have finished the adjustment of the switching points of the device.
- Press now button 4 to exit the switching point adjustment menu.
6.3. Minimum/maximum-alarm
This chapter describes how to adjust the device„s alarm boundaries for min-/max-alarm-monitoring.
This inst
ruction demands that you selected “
AL.F1
“ as your desired output function like it is explained in
chapter 5.1.
- Press button 1
(if not already done).
The device will be displaying “
AL.Hi
“. (maximum alarm-value)
- Use button 2 or button 3 to set the desired value, the device should turn on its maximum-alarm.
- Press button 1
to validate your selection. The display shows “
AL.Hi
“ again.
- When pressing button 1
again, the device will be displaying “
AL.Lo
“. (minimum alarm-value)
- Use button 2 or button 3 to set the desired value, the device should turn on its minimum-alarm
- Press button 1
to validate your selection. The display shows “
AL.Lo
“ again.
- When pressing button 1
again, the device will be displaying “
A.dEL
“. (delay of the alarm-function)
- Use button 2 or button 3 to set the desired delay of the alarm-function.
Note:
The unit of the value to be set is in [sec.]. The device will turn on the alarm after the minimum
or the maximum alarm value was active for the delay-time you have set.
- Press button 1
to validate the delay time. The display shows “
A.dEL
“ again.
Example: You want to have a temperature alarm-monitoring of a greenhouse. The alarm should start when
the temperature rises above 50°C or falls below 15°C.
Therefore your settings will be 50°C for the maximum alarm-
value “AL.HI“ and 15°C for the mini-
mum alarm-
value “AL.Lo“.
=> The alarm will be starting after the temperature rises above 50°C and stays above 50°C for
the entered delay time or after it had been falling below 15°C and stays below 15°C for the en-
tered delay time.
Please note that the alarm-outputs are inverted! This means, that the output will be active when there is no alarm!
- When pressing button 1
again, the display shows “
AL.Hi
“ again.
Now you have finished the adjustment of the alarm boundaries of the device.
- Press now button 4 to exit the alarm boundaries configuration menu.
