Installing the StepMetrix Step-Up
1. Place the Ste pMetrix step-up on the flo or before th e
StepMetrix sensor module. Do not fasten the step up to
the floor at thi s point. T he positioning rails need to be
assembled first (see Figure 17).
2.2.3
Installing the StepMetrix Step-Down
1. Place the StepMetrix step-down on the floor after the
sensor module.
2. Do not fasten the step-down to the floor at this po int.
The StepMetrix p ositioning rails must b e assembled
first (see Section 2.2.4).
2.2.4
Installing the StepMetrix Positioning Rails
The StepMetrix positioning rails are used to center the
cows on the StepMetrix sensor module. To inst all
them, perform the following steps:
1. Place the p ositioning rails in the step-do wn and ste p
down. Bolt the rails in place (see Figure 17).
2. Slide the step -up and step-down toward the sensor
module, connecting the positioning rails together with
the plastic antenna supports as shown in Figure 17.
3. Position the step up and step-down so there is a 1-inch
(25 mm) gap bet ween each step and t he sensor
module.
4. Walk on th e step-up and step-down to check for
rocking. If the step up or step do wn rocks place shims
underneath it to prevent rocking.
5. Fasten the step-up and the step-down to the floor using
concrete anchors (see Figure 17).
2.2.5
Installing the StepMetrix ISO ID antenna
— NOTE ———————————————————
⎯⎯⎯
The wire lengths of the load cell cables and ISO ID antenna
cannot be c hanged; therefore the location of the controller
must be considered before installation.
The StepMetrix ISO ID antenna must be i nstalled at the
center of, and parallel to, the positioning rails.
1. Position the ISO ID antenn a on p ositioning rails and
drill holes in t he ISO ID an tenna. Locate the hol es
within the area bordered by the groove in the antenna’s
surface, as shown in Figure 18, detail A. The antenna
must not be drilled outside this area. The top of the
antenna should be 72” a bove the floor. Drill h oles
through the plastic sheet of the p ositioning rails at the
center of the ID antenna. Mount the antenna using the
supplied hardware (see Figure 18).
