Installation
Before attempting any installation make sure that all power is turned off to
the equipment being worked on.
As mentioned previously, the
AA1069
card is
a stand alone module and can be installed in a variety of ways. It should be
mounted in a protective enclosure, which is well ventilated. For mounting, there
are four holes, as shown in Fig. 1B, for use with stand-offs, or the fast-track that
is supplied may be used. The card requires a 120 VAC supply, which should be
fused at 1.0 AMP. Referring to Fig.’s 1A and 2 make all external interconnections
using shielded twisted wire. All wiring should be in accordance with good stan-
dard practices and any codes that may apply.
Note: Some Model Drives require the use of the AA1081 Inverter / Buffer
card with the AA1069 Module. Please refer to Appendix 1B for installation
and set-up.
Initial Set-up
Since the
AA1069
card is designed to be used in a variety of winder applica-
tions, and with various SAFTRONICS drives, the initial settings suggested in
Table 1 are for reference only. The final settings will be dictated by the particular
application in which it is used. Referring to Table 1 and Fig.’s 1A and 2, proceed
as follows for the initial set-up.
1 -
With the drive disconnected
and the
AA1069
installed as above, apply
power to the card. Temporarily connect a jumper from terminal 8 ( (-) 12 V)
and 10 (Enable). Adjust RV2 (Minimum Adjustment) to fully CCW (0 V ). Then
apply the appropriate full scale LINE SPEED REFERENCE voltage, between
terminal 1 or 2 and terminal 7 GND. i.e., the voltage that would represent
maximum line speed. Ensure that the proper jumpers are in place, L1 and L4
for a positive reference, or L2 and L3 for negative.
2 - Connect a voltmeter to terminal 3 ( Supply) and terminal 7(GND)
then adjust RV1(Speed Adj.) for +10 V. Check that terminal 4 (Dancer (-)
Supply) is (-) 10 V. Next check that the slider on both the Dancer (terminal
13) and Dancer Position (terminal 6) potentiometers adjust from (+/-) 10 V
throughout their range with 0 V in mid-position.
NOTE: the Dancer slider should read 0 V when in it’s mechanical neutral
position. Also, the polarity of the Dancer input at terminal 13 must be in
a direction as to provide the proper feedback.
3 - Ensure that jumpers L5 and L6 are in, and set the Dancer slider to it’s neutral
position (0 V) (or disconnect it) . Adjust the Position Input potentiometer for
(-) 10 V at terminal 6. Connect the voltmeter to terminal 11 (Proportional
Output) and adjust RV6 to 1 V output or approximately 10% of the
Dancer input.
