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.
