4. Insert the DRI into the drum. Rotate the DRI (1,
Figure 5-3) so that the DRI shaft (2) engages the drive
inside the drum.
5. Push the DRI into the drum so that the notch is lined up
with the breather (3, Figure 5-2).
6. Secure the DRI with the retaining screws (2, Figure 5-2).
7. Loosen the set screw (1, Figure 5-4) on the side of the
DRI flange.
8. Using the spanner wrench holes (2, Figure 5-4) rotate
the DRI so that the connector (3) is pointed down.
9. Tighten the set screw (1, Figure 5-4) after the DRI is
positioned as desired.
10. Plug in the DRI cable and tighten the collar to secure the
connector.
Programming the Minimum Wrap Indicator
The minimum wrap indicator (MWI) needs to be
programmed to alert the operator when the cable is down to
the third wrap of wire or synthetic hoist rope. To program the
MWI you need to:
1. Run the hoist to the first set point, third wrap of wire or
synthetic rope. This deactivates the alarm output.
2. Remove power from the MWI by disconnecting the DRI
cable (2, Figure 5-5).
3. Remove the sealed Hoist Monitoring System (HMS)
programming button cover screw (1, Figure 5-5) on the
DRI.
4. Push and gently hold the programming button (3,
Figure 5-5) and return power to the MWI by
reconnecting the DRI cable.
NOTE: Use an Allen Wrench or other small tool with a flat,
blunt end approximately 1.5mm or (1/16") in width
and at least 76 mm (3") in length. Use of a pointed
or sharp tool can cause faulty setting or damage to
the HMS. Excess force can damage the HMS
operation.
5. Hold the programming button for at least 2 seconds, but
less than 15 seconds, after power is applied and
release.
NOTE: Holding the button for longer than 15 seconds puts
the HMS into Shipping Mode for Series A
units.(See Figure 5-5). See Shipping Mode for
more information.
6. Run the winch to the second set point.
NOTE: It is recommended to transition to the second layer
as the second set point.
7. Gently press and hold the programming button for 1-2
seconds, then release.
8. Replace the MWI/HMS programming screw. Tighten to 7
in-lbs.
NOTE: Failure to replace the programming screw (1,
Figure 5-5) could effect the operation of the MWI.
9. The MWI setup routine is complete.
