SYSTEM START-UP AND ADJUSTMENT
Manual Tension Adjust (Front Panel)
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 block TB1 . This
voltage should be between 24 VAC and 30 VAC .
q
4 . Remove power from the control system and wait
a pproximately 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 between 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 . Positive (+) to
terminal 4 and negative(-) to wire .
q
6 . Reapply power to the control system .
q
7 . Place mode selector switch in the brake “off”
position . Meter should read zero current and
brake should be free-wheeling .
q
8 . Place mode selector switch in the brake “on” or
“stop” position . Meter should read 270 to 280
milliamps and brake should be locked-up tight .
q
9 . Place mode selector switch in the “run” position
and set the tension adjust potentiometer to zero
or full counterclockwise position . Meter should
read zero output current to the brake .
q
10 . Rotate the tension adjust potentiometer from fuIly
counterclockwise to fuII clockwise slowly noting
the output current increases from zero to 270 to
280 milliamps at maximum output .
q
11 . This concludes check-out of the control system .
Remove power and allow approximately 30
seconds before proceeding to the next step .
q
12 . Remove the meter and re-attach the sense
magnet lead to terminal 4 of terminal strip TB1
and secure .
q
13 . Re-apply power to the control system .
q
14 . Adjust the tension potentiometer for the desired
brake level required for the operation .
Note:
If start-up and adjustment procedures do not
produce the desired results, consult the troubleshooting
section of this manual .
q
15 . If a remote mode selector switch is used, repeat
steps 7 through 13 using the remote mode
selector switch .
q
16 . Attach the cover to the control chassis using the
two cover screws supplied with the control .
Remote 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 VAC 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 . The meter should read zero output
current and the brake should be freewheeling .
q
8 . Place the mode selector switch in the brake on or
“stop” position . The meter should read maximum
output current of 270 to 280 milliamps to the
brake . The brake should be locked up tight .
q
9 . Place the mode selector switch in the “run”
mode . Set the front panel tension adjust
potentiometer to its maximum clockwise position .
Set the remote tension adjust potentiometer to its
fully counterclockwise position . The meter should
read zero output to the brake .
q
10 . Rotate the remote tension adjust potentiometer
from its minimum, fully counterclockwise position,
slowly to its maximum, fully clockwise position .
Monitor the meter and observe that the output
current goes from zero to a maximum of 270 to
280 milliamps . Leave this potentiometer at its
maximum setting .
q
11 . Rotate the front panel tension adjust
potentiometer slowly from its fully clockwise, or
maximum setting, to its fully counterclockwise,
or minimum setting . Monitor the meter observing
that the current goes from 270 to 280 milliamps
to zero at the minimum setting .
q
12 . This concludes the check-out of the control
system . Remove power from the system and wait
approximately 30 seconds before proceeding to
the next step .
q
13 . Remove the meter from in series with the sense
magnet and terminal 4 of terminal strip TB1 .
