5-4 Observing Flow Velocity Waveforms
■ When molding is started, flow velocity waveforms are displayed
.
Indicates the
measurement range of
passage waveform

Minimum voltage value
※ If waveforms are not displayed, check the following.
① Has resin reached the sensor?
→Check the molded parts and the sensor mounting position.
② Is the display channel checked?
→Confirm the check mark in the channel information display section (at the right side of the
operation window).
③ Is the system connected correctly (sensor, relay amplifier, power supply, LAN and trigger signal)?
→Check the Network settings by referring to Section 2-4, "Connections in the system" on Page 7.
Isn't the sensor damaged?
④
→Check the sensor by referring to Section 7-3 "Checking the Operation of Sensor" on Page 30.
※ If the peak of the velocity waveform exceeds 5000mV and is saturated, the light intensity needs to be
adjusted. Adjust the light intensity so that the peak and the trough of the waveform will not be
saturated.
(For the light intensity adjustment procedure, refer to "Adjusting the Light Intensity of Relay Amplifier"
on Page 34.)
