HOLD

When the indicator is in one of the following states,
this LED comes on.

- The indicated weight value is held.

- The hold signal is input in the rear panel terminal base.

- The digital indicator status is HOLD.

GROSS

When the indicated weight value is a total
weight, this LED comes on.

NET

When the indicated weight value is a net weight,
this LED comes on.

TARE

When the indicated weight value is a tare weight
or the indicator is in the tare subtraction status,
this LED comes on.

CZ

When the indicator is within ± 1/4 scale division
from the zero point, this LED comes on to
indicate the true zero point.

ZT

When the indicator is Zero Tracking (ZT), this
LED comes on.

MD

When the indicator status is stable, this LED
comes on. (This may come on in the unstable
status depending on the indicator type.)

Digital Indicator

（※ This indicator is based on the

overflow indication of our F360A
series, so the indication may be
different from the indication of the
LD514 main unit depending on the

indicator that is connected.）

　　　　　 Connection Fault Indication

When the dedicated serial interface input short-circuits
or wire breaking occurs, or when the rotary switch is not
selected correctly, blanking (all digit OFF) takes place
and all the status indicating LEDs come on.

In this case, check the following items and take a proper

measure.

- When the dedicated serial interface is used, check if it is
correctly connected or any wire breaking does not
occur.

- Check if the rotary switch is set according to the
specified number.

- Check if the indicator is normally operated.

When the all-digit indicating part and the status
indicating LEDs do not come on, check the following
item and take a proper measure.

- Check if the power supply (100 to 220 V AC) is
correctly input.

FRONT PANEL

Numeric display part

This part indicates the following 7 types of value.

- Total weight

- Net weight

- Tare weight

- Load cell indicator interrelated value (Standard mode)

- Load cell indicator interrelated value (LD151 compatible mode)

- Digital indicator interrelated value

- Over-scale indication

　　　　Self-check (self-diagnosis) method

The LD514 can make a self-diagnostic test by special operation
or a command from the indicator. If any fault is not found by
self-diagnostic test (ROM check), a visual check is started in
succession. At the visual check, a decimal point and a number
of 0 to 9 are displayed for each digit on the display unit.
Visually check if the numeric value can be normally indicated.

The self-check is made in the following two cases.

- The power supply is turned on after the rotary switch is set to
the self-check mode.

When the rotary switch is set to No.8 and then the power
supply is turned on, the check is repeated until this setting on
the rotary switch is changed.

- A self-check command is given from the indicator that is
connected.
For making a self-check, the load cell indicator such as F805
outputs a check command to the LD154. Some types of
indicator may not output a check command. For details, refer
to the instruction manual for the respective indicator.

Visual check

If the indication is provided as shown above, the
display unit is normal.

SI/F terminal base

This is a terminal base for SI/F
input (two-wire serial interface
input). The applicable wire
material is a parallel 2-core
cable, cabtyre cable, etc.

SIF

Frame ground

This is a grounding terminal. Be sure to
ground this F.G terminal to prevent an electric
shock and a fault due to static electricity.

AC power supply
input terminal base

Connect the attached AC power cable.The input
voltage is 100 to 240 V AC and the frequency is
50/60 Hz.

Connecting to Cage Clamp Terminal Block

As the SI/F terminal and hold input terminal is using the cage clam
system terminal stand, connecting is simple.

1.Strip the casing 0.2in(6mm) on the cable to be connected.

2.Twist the bare wire to fit the terminal hole.

3.Insert the supplied screwdriver into the upper hole and lift
upward

4.Insert he twisted wires into the lower hole.

。

5.Pull the screwdriver out from the upper hole.

6.Make sure cable is clamped securely and does not come

out wight a slight tug.

・Cable can be from 24 to 12AWG (0.2 to 2.5MM

2

).
It is not necessary to solder the cable wires or to
fix a solderless terminal

・If several cables to be inserted to the same hole,

twist those cable wires together and insert.
