11 FORM NO. L-21208-C-0908
90: Diameter Measure Flag Sent as integer, read & write. Diameter Measure Flag is only to be used after registers
87, 88, and 89 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 register. RSTC1000 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 register. RSTC1000 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.

ALIBRATION
Set the Maximum Tension Setpoint before calibrating the tension sensors. Afterwards, re-calibration of tension sensors
is necessary whenever Maximum Tension Setpoint is changed.
73 – 74: Minimum Tension Setpoint Floating point number sent as long integer * 1000 in units of lbs, read & write,
range is 0.000 to 10,000.000 lbs. Minimum Tension Setpoint value must be less than Maximum Tension Setpoint
value. Read the current minimum tension setpoint or write a new minimum tension setpoint value.
Example: 55.742 lbs
Register 73: 0 (msw)
Register 74: 55742 (lsw)
Tension Setpoint = ((0 * 65536) + 55742) / 1000 = 55.742 lbs
75 – 76: Maximum Tension Setpoint Floating point number sent as long integer * 1000 in units of lbs, read & write,
range is 0.000 to 10,000.000 lbs. Maximum Tension Setpoint value must be greater than Minimum Tension Setpoint
value. Read the current maximum tension setpoint or write a new maximum tension setpoint value.
Example: 324.742 lbs
Register 75: 4 (msw)
Register 76: 62598 (lsw)
Tension Setpoint = ((4 * 65536) + 62598) / 1000 = 324.742 lbs
77: Tension Calibration Set Sent as integer, read & 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 calibra-
tion set.
Example 3 – Tension Calibration Set 3
Register 80: 0 (msb), 3 (lsb)
