<The attention and the check method on limit switch attachment>
When the lever working range of a torque wrench is small, a limit switch cannot be struck and a transmitter may
not send. In limit switch attachment, be careful enough and carry out.
<Input Judgment time for transmitter>
Transmitter don
’
t transmit when the signal from limit switch is within 40ms.
This function prevent transmitting the signal at striking the limit switch when the torque wrench is fallen.
When you install a limit switch and a transmitter, it can not send the signal that you strike a limit switch by your
finger. But it is based on the abovementioned processing.
In the case of tightening the limit switch in normal, the time is approx 100ms-170ms.
In the case of striking the limit switch by being fallen, the time is approx 20-30ms.
Input judgment time of transmitter is set by above cause.
<Installation the receiver>
■
Install this machine in the place where it can be easily viewed from the Transmitter and also an electric wave
can be stably received.
■
Set the antenna so that it is not parallel to the metal plates and keep away it from metal plates as far as
possible.
■
Feed the stable power supply (DC24V) with less variation.
When you use with AC power supply, please use the AC/DC adaptor “ADB24050”of an option.
■
Make a wiring for the output terminal block.
Output turns on with relay contact. Once output turns on, short-circuited condition is made between terminals.
Once the rated contact load is exceeded, inner circuit might be damaged. Use an extreme care.
