Use sluice gate valves, knife gate valves or iris gate valves with electric-drive
three-step controller as control elements.
Analog-drive slide valves cannot be used.
We recommend the following regulating times (time elapsed between valve
completely open and completely closed) for the selection of gate valves:
</= 300 mm (11.8 in) diameter: min. 60 seconds
</= 500 mm (19,7 in) diameter: min. 120 seconds
</= 800 mm (31.5 in) diameter: min. 240 seconds
</= 1000 mm (39.4 in) diameter: min. 300 seconds
For the correct driving as well as for error monitoring of the slide valve, the Way-
End-Switches “OFF“ and “ON“ as well as the torque switches “ON“ are a manda-
tory requirement. These signals have to be connected to the digital inputs of the
OCM Pro CF. Please note to select gold-plated contacts in order to ensure con-
tact reliability. Connect a signal relay between switches and OCM Pro CF digital
input to safely conduct the 10 mA input current.
Analog position feedback to OCM Pro CF is not planned.
The OCM Pro CF operates as a three-step controller with surge detection, quick
close control, slide valve monitoring and automatic flush function.
To drive the regulating unit, the digital inputs 4 and 5 are assigned as default.
Hence, digital output 4 as “slide valve closed“ and digital output 5 as “slide valve
open“ are defined.
Analog input 4 is determined for input of external setpoint values (see chapter
7.3.5)
Note
-
The assignment of the digital outputs to the regulator cannot be modified.
-
The input current on the digital inputs of the OCM Pro CF is 10 mA. Please
ensure contact reliability by selecting sufficient contact materials on the end
switch of the control slide valve.
