Pressure values transferred from the SLC data table to the module must be
integer numbers in units of PSI. If using the Pro-Set 200 Injection Control
System, the ladder logic provides pressure values in the correct format.
4. Configure the module with jumper plugs
Each channel is independently configurable. Jumper-plug configurations
selected here must match G-file bit selections done next in section 5.
The module’s default channel input configurations are:
•
channel 1: mold pressure sensor (low-level) connected to the module
•
channel 2: injection pressure sensor (high-level) connected to module
You may use these default configurations or change them as needed.
Select gain and zero-reference with jumper plugs
Important:
For a 5% FS zero reference, a 2mv/V sensitivity and gain of
450 give an amplified 9.0V operating range of 0.5-9.5V dc. This lets the
module and software continuously autozero the lo-end signal for variations
due to pre-load and/or changes in temperature.
