Key Points of the Procedure
1. The limit values that are set can be checked by pressing . The balance displays the lower-limit value after
showing [  ] and the upper-limit value after showing [  ].
2. If a mistake is made, press during the setup of actual quantities or during the setup of values.
3. If is pressed while a value is flashing, an actual quantity will be set based on the weight currently loaded
on the balance. Press at this time to display the value input screen.
4. If the
[ ]
mark lights up for all three judgment indicators (HI, OK and LO), the lower limit value set exceeds the
upper-limit value. Check the values, since mistakes can occur with entries, as in cases when the upper-limit value is
specified with a negative sign.
5. When the [M] mark is flashing on the value input screen, the sign on the left end can be changed. Press to
switch between the positive and negative signs.
3.4 Input/Output Functions
Figure 3-1. Terminal Numbers and Functions
Compatible plug: TCP 0556-01-0201 (Hosiden - supplied with balance)
Tare subtraction (zero adjustment) is possible by connecting an external tare subtraction input and a signal
ground through contacts or a transistor switch. When following this procedure, secure a connection time of
at least 400 milliseconds. When the switch is off, the voltage maximum is 15 V; when the switch is on, the sink
current is 20 mA or less.
Before plugging in the connectors, unplug the AC adapter.
