Key Switches

(O) Mark of the pressed key moves upward.

Control I/O

(O) Mark of the ON-terminal moves upward.

The terminal of the displayed number is on.

Standard Serial

Output

Pressing the [ENTER] key sends “1 2 3 <CR><LF>” at the baud rate set

in the general function setting.

OP-01 BCD

<Hold>

(O) Mark moves upward when “Hold” is on.

The terminal of the displayed number is on.

OP-03

(RS-422/-485),

OP-04

(RS-232C)

Pressing the [ENTER] key sends “1 2 3” based on setting made in the

OP-05 Setpoint

Unit

The number of COMMON terminal of the digit to be read is shown.

The value of the digit to be read is shown.

OP-07 Analog

Output

A current value (mA) being output is displayed.

The current value can be changed with the [∧] or [ ∨] key.

A load cell signal value being input is displayed in the unit of mV/V.

When this value is within a range of 0 to 2 mV/V with no load, it is likely

that the load cell is damaged or it is connected improperly.

Since an offset can be added to an A/D input, using the [ ∧ ] or [ ∨ ], the

A/D converter can be checked for operations without applying a load to

the load cell.

Procedure Problem Cause

With +SIG and –SIG Load Cell terminals shorted, 0.0

mV/V is not displayed.

Load Cell excitation voltage or output

voltage is incorrect, or Load Cell is

wired incorrectly.

When not loaded, the displayed value is out of a range

of 0.0 mV/V to 2.0 mV/V.

Damaged Load Cell

When loaded, the displayed value is smaller than that of

procedure 2, or larger than 3.2 mV/V.

Load Cell is wired incorrectly, or

incorrect rate of Load Cell.

* When the [ ∧ ] or [ ∨ ], key pressed, the displayed

value does not increase.

Load Cell is incorrectly wired.

A/D Converter

* Note the value increase for future reference.

ROM version

ROM version is displayed.
