Operation
3.1
Learning a Process
1.
From the main menu select the
LEARN
icon.
2.
After the press has been set up and the crimp verified, press the
ENTER
key to start the learn process.
NOTE: BE SURE THE CRIMP IS VERIFIED. THE CRIMP MONITOR WILL LEARN ITS LIMITS BASED ON
THIS CRIMP.
3.
The
CFM GAIN
has already been set in the setup configuration. After the first crimp, the internal signal
conditioning circuits will be configured and the learning process will begin.
4.
The crimp force monitor requires a minimum number of samples set in the configuration and then following
successful learn, will automatically change to the
RUN
mode.
3.2 Auto-Gain Feature
At the start of the learning process and following the first press cycle, the crimp force monitor automatically adjusts
the force sensor input gain or amplification factor relative to the peak crimp force. Small gauge wire crimping for
example, will have a higher gain to optimize the analysis. In some very low crimp force applications, it may not be
possible to detect the crimp force signal following the press cycle.
If no signal is detected while in the
GAIN
stage, press the key to initialize the
Auto-Gain
feature.
1.
After crimping a wire, press the key.
2.
The crimp force monitor will automatically adjust the internal signal conditioning circuits based on this sample
crimp and the learning process can continue as normal
3.
If no signal is detected during the
Auto-Gain
process, the crimp force monitor will display the following error
message.
Please check the sensor and sensor cabling for damage and/or proper installation.
3.3
Information Screen
From the main menu select the information icon.
Gain Level
is showing the selected level the unit is using.
Headroom
is the comparison between the peak force of the reference signature and the peak force of a crimp
with no wire (terminal only). Headroom is the amount of crimping force specifically related to the compression of
the wire core bundle and is calculated using the following formula:
