Safety Precautions
Refer to Precautions for Correct Use on page in the Technical Guide for Thumbwheel Switches.
Handling
The molded components of the Switch use polyacetal resin and
ABS resin. It is recommended that alcohol is used to wipe off dirt
and smudges from the molded components. Take care to prevent
the alcohol from getting inside.
A7BS/A7BL Thumbwheel Switches are not drip-proof. Do not use
them in areas subject to water or oil.
Do not allow solder flux or alcohol to enter the Switch.
Setting Numbers
Locking Type
Set with the setting button by raising it.
Return the button to its original position after setting. It is then
locked to prevent rotation, and the set numbers will not change
accidentally.
To separate the Switches, use a flat-blade screwdriver as shown in
the following figure to release the hooks on the top and bottom and
then separate the Switches. Be careful not to bend the hooks.
Models with External Stoppers (A7BS-20@-S)
With the A7BS-20@-S, any range can be set externally using the
Stopper Pin. Insert the Stopper Pin using the following procedure:
Example: To Display the Range 0 to 7
1. Any number within the range of (0 to 7) can be chosen to limit the
numbers displayed in the display window. (In this example, 8 and
9 are outside of this range.)
2. First, insert the Stopper Pin in the hole
in front of the lower limit (“0”) for the
number to be defined.
3. Next, inset the Stopper Pin in the hole
past the upper limit (“7”) for the number
to be defined. (The Stopper Pins then
surround the exact range to be
defined.)
4. Confirm that the (+) push-button can no
longer be pushed after reaching the
upper limit of (“7”).
5. Confirm that the (-) push-button can no longer be pushed after
reaching the lower limit of (“0”). This completes the setting.
