q
14 . Reconnect the sense magnet lead to term in al 4
of terminal strip TB1 and re-tighten the screw .
q
15 . Reapply power to the control system .
q
16 . Adjust the front panel tension adjust
potentiometer to the maximum output level
desired for the application . Adjustment between
maximum level and zero can now be made
through the remote tension adjust potentiometer .
Note:
If start-up and adjustment procedures do not
provide the desired resuIts consuIt the troubleshooting
section of this manual .
q
17 . If remote mode switching is used, repeat steps
4 through 15 using the remote mode selector
switch .
q
18 . Attach cover using the two screws supplied with
the control .
Roll Follower Tension Adjust
q
1 . Apply power to the control system .
q
2 . Check that the green LED marked “power” is on .
q
3 . Using an AC voltmeter, measure the AC voltage
at terminals 2 and 3 of terminal strip TB1 . This
voltage should be between 24 and 28 VAC .
q
4 . Remove power from the control system and wait
approximately 30 seconds before proceeding to
the next step .
q
5 . Remove the sense magnet lead from terminal
4 of terminal strip TB1 and insert a DC current
meter in series with the lead of the sense magnet
and terminal 4 of terminal strip TB1 .
Note:
A DC current meter with the capability of reading
0 to 500 milliamps should be used . Connect the positive
(+) to terminal 4 and the negative (-) to the sense magnet
wire .
q
6 . Reapply power to the control system .
q
7 . Place the mode selector switch in the brake off
position . Meter should read zero current and
brake should read zero current and brake should
be freewheeling .
q
8 . Place the mode selector switch in the brake “on”
or “stop” position . Meter should read 270 to 280
milliamps and the brake should be locked up
tight .
q
9 . Place the mode selector switch in the “run”
position . Set the front panel tension adjust
potentiometer to its maximum clockwise setting .
Note:
Refer to Chart 1 for various inputs and outputs
when using the roll follower system .
q
10 . Place a second DC voltmeter between terminals
2 and 4 of terminal strip TB2 .
Note:
A DC voltmeter capable of measuring zero to 10
volts DC should be used . Connect positive (+) to terminal
2 and negative(-) to terminal 4 .
q
11 . With the roll follower potentiometer disconnected
from the roll follower arm, position the follower
arm to the true zero position . This should be the
center line of the unwind spindle .
q
12 . Adjust the roll follower potentiometer to obtain a
zero voltage reading on the voltmeter connected
between terminals 2 and 4 of terminal strip TB2 .
q
13 . Connect the roll follower potentiometer to the roll
follower arm . After coupling the follower arm to
the potentiometer, recheck the voltage between
terminals 2 and 4 of terminal strip TB2 to insure
the voltage is still zero VDC .
q
14 . Place a full roll of material on the unwind stand .
q
15 . Set the roll follower arm on the unwind roll .
q
16 . Check the voltage between terminals 2 and 4
of terminal strip TB2 and refer to Chart 1 . If the
voltage reading is less than 2 .5 VDC, refer to
Chart 1 for the maximum percentage of starting
torque available .
Note:
If maximum starting torque available is less than
the actual starting torque required, then the amount of
angular travel of the roll follower potentiometer must be
increased .
If the voltage reading is greater than 2 .5 VDC,
decrease the front panel tension adjust until a 2 .5
VDC reading is obtained . This will set the system
at 100 percent torque level .
q
17 . Adjust the front panel tension adjust for
the desired starting torque required for the
application .
q
18 . Start the machine and draw the web through .
q
19 . Monitor the voltage at terminals 2 and 4 of
terminal strip TB2 as well as the brake current . As
the roll diameter decreases, the sensor voltage
and the brake current will decrease keeping the
tension relatively constant .
q
20 . After an initial run has been completed, remove
power from the system and wait approximately
30 seconds before proceeding to the next step .
q
21 . Remove the meter from in series with the sense
magnet lead to terminal 4 of terminal strip TB1
and tighten the screw .
q
22 . Disconnect the voltmeter used from terminals 2
and 4 of terminal strip TB2 .
q
23 . Re-apply power to the control system .
q
24 . If the remote mode selector switch is used,
repeat steps 4 through 9 and step 21 using the
remote mode selector switch .
Note:
If start-up and adjustment procedures do not
provide the desired resuIts, consuIt the troubleshooting
section of this manual .
q
25 . Re-attach the cover using two cover screws
supplied with the control .
