Set ANLG OUT 3 SIG TYPE (P.419) to 0 to 10 volts or 4 to 20 mA, depending on
the type of input signal the dancer transducer requires.
▲
Set ANLG OUT 3 GAIN ADJ (P.420) to specify the maximum value of the analog
output when the dancer loading input is at its maximum .
Range: 0 to 10 V , +/-10 V , 4 to 20 mA, 10 to 50 mA P.419 =

DANCER LOADING SETUP EXAMPLE
Assumptions:
• When TENSION SETPOINT (P.854) is set to MAXIMUM , TENSION DEMAND (P.844) is at
4095 counts.
• When TENSION SETPOINT (P.854) is set to MINIMUM , TENSION DEMAND (P.844) is at 0
counts.
• The pneumatic transducer uses a 4 to 20 mA input, zero loading (tension) is
equivalent to 4 mA, and maximum loading (tension) is equivalent to 20 mA.
Under these conditions:
• Set MAX DANCER LOAD (P.831) to 4095 counts, where 4095 equals maximum web
tension.
• Set MIN DANCER LOAD (P.832) to 0 counts, where 0 counts equals zero web
tension at 4 mA.
