o
9 . Place the mode selector switch in the “run”
position and set the tension adjust potentiometer
to zero (or fully counterclockwise) . The meter
should read zero current output to the brake .
o
10 . Slowly rotate the tension adjust
potentiometer from fully counterclockwise to fully
clockwise, noting that the output current
increases from zero to 345-375 mA at maximum
output .
o
11 . This concludes checkout of the control
system . Remove power and allow approximately
30 seconds before proceeding to the next step .
o
12 . Remove the meter and reattach the sense
magnet lead to terminal 1 of terminal block TB2
and secure the lead . Proceed to step 13 .
All other 2 wire tension brakes
o
5 . Attach a DC voltmeter to terminals 2 and 3 of
terminal block TB2 .
Note:
A DC voltmeter with the capability of reading 0
to 24 VDC should be used . Positive (+) to terminal 2
and negative (-) to terminal 3 .
o
6 . Reapply power to the control system .
o
7 . Place mode selector switch in the brake “off”
position . The meter should read zero voltage and
the brake armature should be free-wheeling .
o
8 . Place mode selector switch in the brake “stop”
position . The meter should read approximately 24
VDC and the brake should be locked up tight .
o
9 . Place mode selector switch in the brake “run”
position and set the tension adjust potentiometer
to zero or full counterclockwise position . The
meter should read zero output voltage to the
brake .
o
10 . Slowly rotate the tension adjust potentiometer
from fully counterclockwise to full clockwise,
noting the output voltage increases from zero to
approximately 24 VDC at maximum output .
o
11 . This concludes check-out of the control
system . Remove power and allow approximately
30 seconds before proceeding to the next step .
o
12 . Remove the meter from terminals 2 and 3 of
terminal block TB2 and secure .
o
13 . Reapply power to the control system .
o
14 . Adjust the tension potentiometer for the
desired brake level required for operation .
Note:
If start-up and adjustment procedures
do not produce the desired results, consult the
troubleshooting section of this manual .
o
15 . If a remote mode selector switch is used,
repeat steps 5 through 13 using the remote
mode selector switch .
o
16 . Close the cover to the control chassis using
the cover screw supplied with the control .
Remote 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 voltage
at terminals 4 and 8 of terminal block TB2 . This
should be approximately 115 VAC or 230 VAC,
depending on the input 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 .
