Rapid-Air DUAL SWIVEL REEL: 100 & 1000 SERIES - Manual (Page 6)

TAUT STOCK
The Taut Stock feature monitors the loop between the reel and the external equipment.
If the loop gets small enough to possibly cause damage to the reel, the interface con-
tacts change state and stop the external equipment.
If it is desired to monitor the reel then the following write up will explain how to connect
and adjust this feature.
The Taut Stock feature is built into the Rapid-Air board 69100035 and wires to external
terminals 7-8-9. The terminal #9 is common and from terminal 8 to 9 is normally
closed contact with power on the unit. Terminal 7 to 9 is a normally open contact with
power on the unit. These contacts are from “relay 2” chip. See diagram. This relay
has to be in place for taut stock to work. There is also a 4 prong post labeled “jump”
that has to be connected so that relay 2 can be activated. To correctly apply the
jumper, locate the post and then locate the plastic 2 prong jumper, insert the jumper so
that the left 2 vertical posts are covered. Once this is in place the taut stock feature
can be tuned.
To tune the taut stock, check that there are no connections on the terminals 7 - 8 &9,
except those that were factory connected. Attach an OHM meter to terminal 9 & 7 with
the meter set to Ohms.
Start the reel and raise the dancer arm so that the reel is running at maximum speed.
Lower the dancer arm up to a point that the stock would be taut. Hold the dancer at
this position and adjust the pot R7 of board 69100034 until the contact changes state.
Release the dancer arm. The contact should return to normal state. Raise and lower
the dancer arm 2 to 3 times to insure that the contact functions properly. Disconnect
the OHM meter and connect the customer interface.
CAUTION: The contact rating of the relay is 10VA@ 0.5 amps max. Refer to next
page for 69100034 taut stock output.
