1. External control input signal
Activates by shortening with COM. (pin No. 1,19) in the output connector of BCD.
BCD output
connector pin No.
Name Operation
31 ZERO When the indicated value on load display is within
±
10 % against the
maximum display value, zero set function will activate by the operation and
make the display “0” compulsively. (Same operation as key operation in the
paragraph 6

−
1.) As for the operational details, refer to the paragraph 7
−
9.
32 A/Z At the same time when Tare weight cancellation (A/Z) function activates
and load display value will become Net weight display (Only when “Net
weight” is selected in Function F
−
02.), “A/Z” on status display will light up
and load display value will light up and load display value will become “0”.

8.
33 A/Z OFF Only while Tare weight cancellation
(
A
/
Z
)
function activates, Tare weight
cancellation clear
(
A
/
Z OFF
)
will activate and at the same time the load
display will become the Gross weight, the “A/Z” on status display will put
off.

27 HOLD While inputting this signal, the target selected with Function F
−
50 is
frozen among display and BCD output, and at the same time the “HOLD”
on status display will light on. As for the operational details, refer to the
paragraph 7

28 LOCK During inputting this signal, all the key input can be locked (prohibition)
and the “LOCK” on status display will light up as well.
29 SEL.1 When “00003=External selection” is selected in the Function F
−
20, the
target of BCD output will be changed by the combination with 2 input
conditions as follows:
Both SEL 1 and SEL 2 are open
：
Interlock with load display
30 SEL.2
Both SEL.1 and SEL.2 are open.
：
Interlock with load display
Short for only SEL.1
：
A/Z cancelled portion
Short for only SEL.2
：
Net weight
Short for both of SEL.1 and SEL.2
：
Gross weight
1,19 COM. Common for input signals (Pin No. 27,28,29,30,31,32,33
)

●
Operation of input signal will be executed after shortening for more
than 100 ms approximately.
●
During the input of HOLD signal, when ZERO signal, A/Z signal, and
A/Z OFF signal(or “ZERO” key, “A/Z A ” key, “A/Z OFF Y ” key) are
input, operation of ZERO, A/Z and A/Z OFF will be executed at the
same time of cancellation of HOLD signal.
●
After inputting the HOLD signal in power
−
off condition, turn on the
power. Then status display of ”HOLD” will be light on, and load
display will clear the indication at the same time. The load value will
be shown simultaneous with the cancellation of HOLD signal.
