o
15 . Adjust the front panel tension adjust
potentiometer to the maximum output level
required for the application . Now set the remote
tension adjust potentiometer between maximum
and zero .
Note:
If start-up and adjustment procedures
do not produce the desired results, consult the
troubleshooting section of this manual .
o
16 . If a remote mode selector switch is used,
repeat steps 5 through 13 using the remote
mode selector switch .
o
17 . Close the control front cover and latch it by
tightening the screw that is provided .
Roll Follower Tension Adjust
o
1 . Apply power to the control system .
o
2 . Check that the green LED marked “power” is
illuminated .
o
3 . Using an AC voltmeter, measure the AC input
voltage at terminals 4 and 8 of terminal block
TB2 . This voltage should be approximately 115
or 230 VAC, depending on the voltage chosen .
o
4 . Remove power from the control system
and wait approximately 30 seconds before
proceeding to the next step .
Electro Disc Tension Brake
Note:
If you are not using electro disc tension brakes,
proceed to step 5 under all other 2 wire tension brake
section .
o
5 . Remove the sense magnet lead from terminal
1 of terminal block TB2 and insert a DC current
meter in series with the lead of the sense magnet
and terminal 1 of terminal block TB2 .
Note:
Use a DC current meter that reads 0 to 500
mA with the positive (+) lead connected to terminal 1
and the negative (-) lead connected to the wire .
o
6 . Reapply power to the control system .
o
7 . Set the mode selector switch to the brake “off”
position . The meter should read zero current and
the brake should free wheel .
o
8 . Place the mode selector switch in the brake
“stop” position . The meter should read 345 to
375 mA and the brake should be locked .
o
9 . Place the mode selector switch in the
brake “run” position and set the tension adjust
potentiometer to its maximum (fully clockwise)
setting .
Note:
Refer to Table 1 for various inputs and outputs
when using the roll follower system
o
10 . Connect a second DC voltmeter between
terminals 9 and 11 of terminal block TB1 .
Note:
Use a DC voltmeter capable of measuring zero
to 10 volts DC .
o
11 . With the roll follower potentiometer disconnected
from the roll follower arm, position the follower
arm to its true zero position, which should be the
centerline of the unwind spindle .
o
12 . Adjust the roll follower potentiometer to a
zero voltage reading on the voltmeter which is
connected per step 10, page 14 .
o
13 . Connect the roll follower potentiometer to
the roll follower arm . After coupling the follower
arm to the potentiometer, recheck the voltage
between terminals 9 and 11 of terminal block
TB1 to insure the voltage is still zero VDC .
o
14 . Place a full roll of material on the unwind
stand .
o
15 . Set the roll follower arm on the unwind roll .
o
16 . Check the voltage between terminals 9 and
11 of terminal block TB1 and refer to Table 1 . If
the voltage reading is less than 0 .8 VDC, refer to
Table 1 for the nominal output current available .
