PTU15
Calibration
The PTU15 calibration can be done in two different ways:
a) By means the P1 and P2 push-buttons.
b) With PC or PLC soft. communication with RS485 port.
a) By means the P1 and P2 push-buttons
To calibrate by-means 2 push-buttons P1 and P2 (see
figure), needs to put the “PTU15” respectively at the
distance refers to 0% and 100% level, in order to
memorise the relevant distance electronically.
In the condition of normal working the PTU15 shows led
flashing (when echo is received).
To calibrate 4mA
needs to put the PTU15 at the distance
at which you want 4mA output current. Wait till the led is
flashing than: press simultaneously P1 and P2, release
them and verify that led will stay fix lightened.
Press two times P1, release it and wait until led is flashing
again before move the sensor. The distance has been
memorised and associated to 4mA output.
To calibrate 20mA
needs to put the PTU15 at the distance
at which you want 20mA output. Wait till the led is flashing
than: press simultaneously P1 and P2, release them and
verify that led will be fix lightened.
Press two times P2, release it and wait until led is flashing
again before move the sensor. The distance has been
memorised and associated to 20mA output.
