to Valve Solenoid
The Thermostat Output turns on (voltage high) when the internal gauge temperature rises above 40ºC, and
turns off when the internal gauge decreases below 35ºC.
The output can be connected to an electrically operated valve as shown.
4.5.3 Index Pulse & Length Thresholds
The Index Pulse and Length Thresholds can be used to control a cutter and provide pre-cut queues to the
process control system so, for example, the line can be slowed prior to a cut. The Index Pulse is configured
to trigger at a specified length interval, and the Length Thresholds can be configured to trigger at preset
lengths before the Index Pulse triggers. The Length Threshold outputs remain high until the Index Pulse trig-
gers and resets. Another way to reset these outputs is to set the Index Pulse Setting to a high value and re-
set the threshold outputs by asserting the Length Reset Input.
The Length Thresholds are available as an alternate output function of the User Scalable Pulse Output .
Example:
Setting Value
Index Pulse Setting 100 m
Index Pulse Length 100 ms
Length Threshold A 90 m
Length Threshold B 80 m
