Selection and configuration of the proportional
controller
1. Mark the "proport. contrl" line using the [Up] and
[Down] buttons, and select using [OK].
2. Select the current input of the ratio value using
the [Up] and [Down] buttons as one of the
following:
– off
– 0-20 mA
– 4-20 mA
– others
and confirm using [OK].
If "others" is selected:
• Adjust the current range freely between 0 and 20
mA by doing the following:
– setting the start-of-scale value in the "Low mA
=" line using the [Up] and [Down] buttons
– setting the full-scale value in the "High mA ="
line using the [Up] and [Down] buttons.
3. Use the [Up] and [Down] buttons to select one of
the following:
– interpulse controller (two-position controller)
– pulse frequency controller
(two-position controller)
– continuous controller
and confirm using [OK].
Selection and configuration of the setpoint
controller
1. Mark the "setpoint contrl" line using the [Up] and
[Down] buttons, and select using [OK].
2. Select the controller using the [Up] and [Down]
buttons as one of the following:
– off
– limit contact
– interpulse controller (two-position controller)
– pulse frequency controller
(two-position controller)
– continuous controller
and confirm using [OK].
If "limit contact" is selected:
3. Use the [Up] and [Down] buttons to select the
switching direction as one of the following:
– downward violation
– upward violation
and confirm using [OK].
If "interpulse ctrl.", "pulse freq. ctrl" or
"cont. controller" is selected, the following applies:
4. Use the [Up] and [Down] buttons to select the
control direction as one of the following:
– downward control (switches with upward
violation of setpoint)
– upward control (switches with downward
violation of setpoint)
and confirm using [OK].
5. Use the [Up] and [Down] buttons to select the
control response as one of the following:
– P (proportional controller),
– PI (proportional-plus-integral controller)
– PID (proportional-plus-integral-plus-derivative
controller)
and confirm using [OK].
Selection and configuration of the combined
controller
1. Mark the line "combined controller" using the [Up]
and [Down] buttons, and select using [OK].
2. Use the [Up] and [Down] buttons to select the
controller output as one of the following:
– off
– interpulse controller (two-position controller)
– pulse frequency controller
(two-position controller)
– continuous controller
and confirm using [OK].
3. Use the [Up] and [Down] buttons to select the
control direction as one of the following:
– downward control (switches with upward
violation of setpoint)
– upward control (switches with downward
violation of setpoint).
and confirm using [OK].
4. Use the [Up] and [Down] buttons to select the
control response as one of the following:
– P (proportional controller)
– PI (proportional-plus-integral controller)
– PID (proportional-plus-integral-plus-derivative
controller) and confirm using [OK].
5. Use the [Up] and [Down] buttons to select the
current input (disturbance variable) as one of the
following:
– 0-20 mA
– 4-20 mA
– other
and confirm using [OK].
If "others" is selected:
• Adjust the current range freely between 0 and 20
mA by doing the following:
– setting the start-of-scale value in the line "Low
mA =" using the [Up] and [Down] buttons
– setting the full-scale value in the line "High mA
=" using the [Up] and [Down] buttons.
