2.0 Installation 2.1 Installation Overview Standard installation of the RoughDeck AX heavy duty floor scale consists of the following steps: 1. Select a site 2. Check levelness and smoothness of site 3. Unpack scales and ramps 4. Adjust the four feet on the scale 5. Anchor ramps and plates that sit above tabs on the scale 6. Connect cable to junction box and indicator 7. Calibrate the unit Access ramp installation is described in Section 2.6 on page 32. 2.
2.4 Assembly The following paragraph presents instructions for installing and adjusting the scale feet. 2.4.1 Installing and Adjusting Feet For load cell protection during shipping, the scale feet are shipped detached from the load cells. The feet are secured to the bottom of the shipping pallet along with the load cell cable, strain relief fitting and product literature. Remove all parts from the envelope.
Electrical Interface to Indicator Twenty feet of 6-wire cable to connect the scale to the weight indicator is supplied with each scale. The cable must be routed to the indicator in a manner that will protect the cable from damage. Two methods of cable protection in non-washdown applications are shown in Figure 4.

To be watertight, each cord grip must be tightened so the rubber sleeve begins to protrude from the hub. Unused hubs must be properly plugged to prevent moisture entry. See the Electronic Replacement Parts catalog to order extra hole plugs. Remove the desiccant from the plastic bag, and insert the desiccant bag into the junction box before closing.
3.0 3.1 Adjustments and Calibration Mechanical Adjustments To accommodate minor unevenness, scale feet can be used to adjust scale height up or down a fraction of an inch. Adjust the feet using the top access foot adjust holes until all feet are contacting the floor equally. No jam nuts are supplied for locking the feet, as there is a slight decrease in accuracy when jam nuts are tightened.
4.0 4.1 Service Information Troubleshooting Guide System does not operate - no display • • • • Power disconnected: Check and reconnect. Indicator fuse blown. Replace fuse. Check for cause. Interface cable cut or disconnected: Repair.
