Magpowr DIGITRAC 2 Instruction Manual - page 12
The following appear only if inertia comp is used:
DIAMETER AT THIS WEIGHT
The roll diameter at the entered weight. Diameter must be
calibrated while the web is running. It is not necessary to calibrate
at the maximum velocity.
ROLL WEIGHT
The roll weight at any diameter in lbs or kgm.
RUNNING VELOCITY
The maximum running web velocity. Typical velocity can be used.
TIME TO ZERO SPEED
The time it takes the machine to stop when running at the above
velocity.
WIDTH AT THIS WEIGHT
This width is used to calculate density for the above roll weight.

TROUBLE SHOOTING
PROBLEM
POSSIBLE CAUSE
SOLUTION OR DIAGNOSTIC
Screen blank or hard to read
Contrast misadjusted
Power select switch
improperly set.
Press SHIFT, B and
éor ê to adjust.
Set 115/230 vac power select switch to the
appropriate voltage.
Output always low
TENSION ON/OFF set to
OFF
If REMOTE TENSION ON/OFF is set to
)TOGGLE( press TENSION ON/OFF on the
keypad once.
If REMOTE TENSION ON/OFF is set to
)LEVEL( one or more of the remote tension
off switches are closed.
E-STOP is active (except
unwind).
E-STOP is wired incorrectly.
JP8-7 not set for the proper
logic supply.
If the internal logic is being used (the factory
default) TB4.2 must be connected to TB4.1
to disable E-STOP. Also verify JP8-7 set to
)INT(.
If an external logic supply is used see
Section 6.5.
Output always high
E-STOP is active (unwinds
only).
E-STOP is wired incorrectly.
JP8-7 not set for the proper
logic supply.
See above.
Cannot enter PROGRAM,
CALIBRATE, BASIC
Not in HOLD mode:
RUN/STOP not wired
correctly.
JP8-7 not set for the proper
logic supply.
If the internal logic supply is being used (the
factory default) TB4.4 must be connected to
TB4.3 to be in HOLD mode. Also verify
JP8-7 set to
)INT(.
If an external logic supply is used see
Section 6.5.
)EXCESSIVE ROLL
WEIGHT
(
Sensor(s) misapplied
The total weight of the sensor idler roll and
shaft must be less than
of sensor rating.
When two sensors are used this is the
combined rating of both (i.e. 100 lbs for two
50 lb sensors).
