2.7 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 UMC600 operates with the EPROM program
KDA1921-1(27C512). To verify the program installed
in the indicator, turn on the indicator and observe the
displayed value at the EP prompt (see Figure 2-4). The
EP prompt displays the family, set, and version level of
the installed EPROM.

EP–1.15

EPROM

Figure 2-4. EPROM Display

Set 1

To ensure that the UMC600 is in proper operating
condition, the indicator can be tested with a load cell
simulator. The input signal should be as close as
possible to the normal system millivolt value.
Figure 2-5 shows the simulator-to-indicator wiring
connection in a six-wire configuration. See Section 2.9
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.

2.12 Digitial I/O Wiring

The standard unit has four outputs for setpoint and zero band control and four discrete inputs that allow the zero,
net/gross, and print function to be operated remotely by contact closure of these inputs to digital ground. Wire any
active digital input and outputs to connector TB3 on the CPU board. Table 2-4 shows the digital I/O assignments for
the TB3 connector and their description.

The three parameters listed in Section 3.1.1 are directly
related to calibration and must be set before proceeding
to calibration mode.

3.1 Digital Configuration

3.1.1 Parameter Overview

Table 3-1 on page 14 lists configuration parameters and
describes their values. The following paragraphs give
the procedure for configuring the UMC600.

3.1.2 Configuration Procedure

1. Unscrew the two screws on the face plate
bracket (Figure 3-1). The bracket drops down,
exposing four program switches on the left side

2. Temporarily remove the unit’s flexible black

display overlay by gently pushing down and
lifting the panel up and out at its center to expose
the configuration and calibration instructions
printed on the surface below. The switch
function table defines the appropriate front panel
switch settings for the CONF and CAL modes.

3. Close switch SW1-2, marked

CONF (2), by

moving to the up position (see Figure 3-2). A
prompt appears with a parameter number and
data value.

The parameter identifier is a number, 1–14, that
correlates to the

CONFIG chart on the upper left of the

switch map panel. Selected data represents the value
being entered into the unit configuration data. For
example, 1 100 sets the indicator to 10,000 graduations
(see Table 3-2 on page 16).

3.1.3 Digital Configuration Parameters

Table 3-1 (shown below) shows an overview of the 14 configuration parameters and their description.
Table 3-2 on page 16 lists the configuration display prompts (Prompt 1), and their value selections for displayed

graduations. Prior to calibration, the UMC600 must be digitally configured, or given its set of operating parameters.
The first three parameter selections are directly related to calibration and must be set up before proceeding to the
calibration mode. These parameters include;

• number of graduation

• resolution

• decimal point location in the weight data, all of which define the scale capacity.
