Installation
Installing the Tup
To install your tup (Instrumented load cell), you must:
•
remove the crosshead weights,
•
bolt the tup to the lower crossmember, and
•
reinstall the weights.
The following sections detail this procedure.
Remove the Crosshead Weights
To remove the weights:
(a) Install the stop blocks and verify that both stacks are the same height. Refer to
Chapter 5 for details on stop block installation and adjustment.
(b) Lower the crosshead onto the stopblocks. Loosen the hand knobs on the front
crosshead plate and remove the weights. When removing the weights, be careful not
to allow the back weight plate to fall off.
Bolt the Tup to the Lower Crossmember
To bolt the tup to the lower crossmember:
(a) Fit the tup into the rectangular cut-out in the bottom crossbar. Attach the tup using
the 1/2-13 inch (1/2 inch screw, 13 threads to the inch) socket-head cap screw. The
15 kN (3.5 Kip) tup (Product No. 8730) should have the 5-pin connector facing the
rear safety enclosure door. All other tups should have the connector facing the right
guide column.
(b) Connect the short 3 ft. (1m) tup cable to the tup. Attach the Amphenol connector
(round 5-pin connector) of the long 20 ft. (6.5m) tup cable to the connector of the
short tup lead. The cable should be routed underneath the back safety enclosure, as
indicated in Step 5 in Utility Connections and Initial Set-up.
(c) Secure the tup cable with the cable clamp located on the right rear corner post. The
cable clamp grips the blue Amphenol connector of the tup cable.
(d) The tup lead should be stress-relieved at the tup using tie wraps. Repeated bending
of the tup lead at the connector could result in damage.
(e) Check that sufficient cable slack is available for the full range of crosshead motion.
Gather any excess slack in the cable and secure with a tie wrap.
