44: Alarm Acknowledge integer, write only. Alarm Acknowledge has a value of 1 to acknowledge an alarm. Writing a
1 to this register will turn off all alarm outputs until the alarm condition is satisfi ed and occurs again.
45: Output On/Off integer, read and write. Output On/Off has a value of 0 for Off and 1 for On. Writing to this
register will affect both RSTC1100 control outputs.
Signal Selection
46: Run/Stop Signal Selection integer, read and write. Run/Stop Signal Selection has the following values:
1 – run/stop maintained
2 – run/stop momentary
3 – run only momentary
4 – run pulsed (encoder)
5 – run/stop signal via network communications
Diameter Calibration
When calibrating the roll diameter signal, send registers 47 through 50 in the order presented here.
47: Diameter Sensor Installed integer, read and write. Diameter Sensor Installed has a value of 0 for no sensor
installed and 1 for sensor installed. When Diameter Sensor Installed is set to 0, values for registers 48 through 50
are ignored and Roll Diameter register is always 0.
48: Diameter – Core Size fl oating point, read and write. The range is 0.0 to 50.0 inches. Core Size is the outside
diameter of roll’s core or any roll diameter that is smaller than the roll diameter used for Large Roll Size.
49: Diameter – Large Roll Size fl oating point, read and write. The range is 0.0 to 400.0 inches. Large Roll Size is
the outside diameter of any roll used for diameter calibration that is larger than the diameter used for Core Size.
50: Diameter Measure Flag integer, read and write. Diameter Measure Flag is only to be used after parameters 47,
48, and 49 have been written.
1. Apply the voltage representing the Core Size to the Diameter Sensor Input terminal and then write a 1 to
Diameter Measure Flag. RSTC1100 will measure this voltage and calibrate the smaller roll size.
2. Read Diameter Measure Flag to determine when previous calibration step is complete. Calibration step is
complete when fl ag = 0.
3. Apply the voltage representing the Large Roll Size to the Diameter Sensor Input terminal and then write a 2 to
Diameter Measure Flag. RSTC1100 will measure this voltage and calibrate the larger roll size.
4. Read Diameter Measure Flag to determine when previous calibration step is complete. Calibration step is
complete when fl ag = 0.
The diameter measurement is now calibrated and ready for use.
Tension Calibration
Set the Minimum and Maximum Tension Setpoint before calibrating the tension sensors. Afterwards, recalibration of
the tension sensors is necessary whenever Maximum Tension Setpoint is changed.
When calibrating the tension sensor signal, write the registers in order for each calibration set.
38: Minimum Tension Setpoint fl oating point, read and write. The range is 0.0 to 10,000.0 lbs but Minimum Tension
Setpoint value must be less than Maximum Tension Setpoint.
39: Maximum Tension Setpoint fl oating point, read and write. The range is 0.0 to 10,000.0 lbs but Maximum Tension
Setpoint value must be greater than Minimum Tension Setpoint.
40: Tension Calibration Set integer, read and write. Tension Calibration Set has values of 1 for Calibration Set 1, 2
for Calibration Set 2, and 3 for Calibration Set 3. Writing a value to this register selects the desired calibration set.
