Instrumentation Setup

All indicators are configured and tested prior to
shipment to ensure that they are fully functional. The
unit can be turned on immediately after connecting the
input power and the load cells.

The UMC 600IS operates with the program KDA—49
programmed onto a 27C512 EPROM. To verify the
program installed in the indicator, turn on the
indicator and observe the displayed value at the EP
prompt (see Figure 2-3). The EP prompt displays the
family, set, and version level of the installed EPROM.

Figure 2-3. Example of EPROM Display

NOTE:

Battery operated units are set up in the factory

with the sleep timer enabled. When connecting the
battery pack, press the ON/OFF button in the lower left
hand corner of the indicator turning the unit on. At the
end of the programmed time the unit automatically turns
off. The factory preset power off time delay is
configurable under option 4 and can be lengthened or
shortened for the operators specific application.

To ensure that the UMC 600IS is in proper operating
condition, the indicator can be tested in a safe area
with a load cell simulator. The input signal should be
as close as possible to the normal system millivolt
value. Figure 2-4 shows the simulator-to-indicator
wiring connection in a six-wire configuration. See
Section 2.6 on page 8 for more information.

NOTE:

Six-wire configuration requires that the +SEN

lead be shorted to +EXC and the –SEN lead be shorted to
–EXC at the simulator only.

Figure 2-4. Wiring Connection to Simulator

Exceeding rated load cell load or
shorting excitation wires may
damage power supply.

NOTES:

Test weights or a water meter calibration can
be used to verify scale performance.

The tilt stand should be secured with 1/4-20
inch screws. The location should be selected
to offer some degree of protection for the
indicator and its associated hardware.

Unprotected cable runs need to be installed in
a method to protect the cable from damage.

All wiring must conform to the National
Electrical Code and RP 12.6.

See control drawing 54136, Sheet 2, in the back of this
manual for system interconnection details.
