1 INTRODUCTION
1.1 PRECAUTIONS BEFORE STARTING
: Before usage, make sure that the latest software version is installed on your device. You can download the
latest software from: www.cla-val.ch
: This equipment must be handled with precaution. CLA-VA electronic products are robust and designed to work
under field environmental conditions, but high shocks and strong mechanical constraints can damage the equipment
and/or alter its functionality.
1.2 TROUBLESHOOTING
1.2.1 NOTHING ON THE OLED DISPLAY
A) Check if there is a proper battery connection in the Electronic Valve Controller. A low voltage (below 3.3V) could
imply having no information on the OLED display.
B) Check that the device is not in standby mode by holding the magnetic stick over the button for 5 seconds.
1.2.2 AN INPUT OR VARIABLE IS DISPLAYED IN RED, ORANGE OR BLUE
See the colour coding convention used on the Electronic Valve Controller for the inputs, outputs and variables in chapter 3.1.
1.2.3 ISSUE WITH THE BEHAVIOUR OF THE VALVAPPS™
Refer to the technical datasheet related to your ValvApps™, and especially the block diagram and the logic scheme
explaining its behaviour.
For any remaining issue, please contact CLA-VAL.
1.3 GENERAL DISCLAIMER
In accordance with our policy of continuous development and improvement, CLA-VAL reserves the right to modify or
improve its products at any time without prior notice. CLA-VAL assumes no liability or responsibility for any errors or
omissions in the content of this document.

Visit www.cla-valpacic.com for more details. Contact the Factory at info@cla-valpacic.com 13
CLA-VAL VC12
Electronic Controller

PID (Proportional-Integral-Derivative):
The "PID" regulation maintains the valve at a configured set-point. Up to four (4) "PID"
regulation loops can be
programmed, each of them offering local or remote set-point capability. Real-time chart view helps to visualize valve
response and fine tune the Electronic Valve Controller accordingly. Perfect valve control is achieved by CLA-VAL
features such as programmable set-point ramping to prevent hydraulic shocks.
Control Curve:
The "Control Curve" offers an easy way to create a relationship between 2 system variables. Using graphical functions
the user draws the
"Control Curve" relationship linking pressure,flow, level and/or time directly on the Electronic Valve
Controller screen. Up to four (4)
"Control Curves" can be profiled allowing specific adaptation such as seasonal
adjustment.
!ACTION!:
Used to take action (or alarms) when a programmable condition is met by forcing an output (relay, solenoid,
4-20 mA). The closing relay can be used to send an alarm to a supervision system. Up to four (4)"!Actions! " can be
programmed including appropriate hysteresis or dead band configuration.
Power Management:
This is used to manage the unit Power and prevent excessive battery discharge. It can be used on flow or differential
pressure.
The power management allows activating default values, according to user pre-programmed rules.

o "Conditional": When the"Conditional" option is chosen, an additional field appears and prompts the user to
specify when the PID should be active. The following field is shown:
The PID loop can be configured to be always active, or when one of the inputs meets a certain condition. In this
case, use the pull down menu that is defaulted to "Always" to select the appropriate input, then use the pull down
menu to the right to select an operator, such as the "Greater than" sign (>), then specify a value.
Example: The following PID loop has been set to be conditional active, only when the Feedback [AI2] is greater
than 50.00 l/s.

Electronic Controller

D) R/T view Tab
This screen describes the relationship between 2 system variables in relation to the X and Y axis.
The arrow located at the bottom-left corner shows the user which way to read the graph:
1. Standard: the input is on the X-axis (in this case, flow) and the output on the Y-axis (in this case, actuated pilot
command for a targeted downstream pressure).
This screen illustrates that as the flow increases, the motorized control pilot will increase the output pressure according to
the graph.
2. Reverse: the input is on the Y-axis (in this case, Reservoir/Tank Level) and the output on the X-axis (in this case,
Target Flow)
This screen describes that as the reservoir level decreases, the targeted flow (to fill the reservoir) increases, and the
motorized control will act accordingly.
: The light on the bottom right of the screen indicates whether the control curve is active (green light) or inactive (red
light).
