Encoder Settings
Based on the selected valve type.
CAUTION! Encoder settings should be made by authorized Valco personnel only!
Correction Factor -
The scaling factor used to adjust an individual/system ratio for the selected channel. This feature
is used on right angle machines when only one encoder is installed and the valves are mounted in sections that are
running at different speeds. To be as precise as possible, the encoder should always be mounted in the section that is
running the fastest.
Encoder Input -
Use to choose a scanner (1 through 4) or the encoder Z pulse to trigger the selected channel.
Valve - Voltage Settings
CAUTION! Valve voltage settings should be made by authorized Valco personnel only!
Acceleration Voltage -
This is the voltage applied to the valve during the valve acceleration phase.
Spike Voltage -
This is the voltage applied to the valve during the spike phase.
Hold Voltage Value -
This is the voltage required to hold the valve after the Acceleration Phase and the Spike Phase.
Valve - Timing Settings
CAUTION! Valve timing settings should be made by authorized Valco personnel only!
Acceleration Time -
This time (in milliseconds) represents the length (duration) of the valve acceleration phase.
Spike Time -
This time (in milliseconds) represents the duration of the spike phase.
Boost Mode (On/Off) -
To overcome problems when a valve sits idle for a long time under high pressure, the Boost
Mode can be enabled for each individual valve (1-4). If the Boost Mode is enabled, it will become active when the
machine is idle for a specified amount of time. Then, the standard valve parameters will be overwritten with higher
values for a defined number of products.
