With configured two-position controllers, the relay
outputs 1 and 2 as well as the output "cont. controller"
can be separately run manually.
By selecting the desired
relay output, the dosing flow
of the pump/pumps can be changed.
1. Having switched to manual operation, the
message "controller stop" is displayed for five
seconds.
– All controllers are switched off.
– The final control elements are closed (set to 0).
2. After that, the device automatically switches to
the mode "display measured value" (first line:
"manual operation").
– The controller control display is shown on the
right side of the display window. Either control
field 1 is present for relay 1, or there is a field
for the continuous controller.
See section 11.6.3 Controller control fields on the
display .
– Since switching to manual operation will cause
all controllers to be switched off, none of the
control fields are filled (there are no areas
displayed inversely).
3. Press [OK] to switch to the subsequent menu.
Three options are available:
• relay output 1
• relay output 2
• continuous controller.
4. Select relay output 1 using the [Up] and [Down]
buttons. Press [OK] to switch to the corresponding
menu.
5. Set the desired dosing rate of the pump using the
[Up] and [Down] buttons.
6. For relay output 2 and the output continuous
controller, proceed similarly to relay output 1.
7. Press [OK] to start the controller at the selected
dosing flow.
– The display shows the controller control display
in its dependence on the selected dosing
flows.
See section 11.6.3 Controller control fields on the
display .
