Basic Operations
Example 1: When a solenoid valve is used to hold work placed by the operator on the
bench and the work is released by the valve and moves to the next production
process once all screws have been tightened. (The work piece is not released
until all screws have been tightened).
1. Connect the external switch to SET and GND on the rear panel terminal block (no
polarity if an external switch is used and common GND if an open collector is used before
connecting the output signal to SET).
2. Connect the + terminal of the solenoid vale to +DC 24 V, and
– terminal to VALVE on the
rear panel terminal block.
3. Connect the switch (contact point) for releasing the work if operations are stopped to
RESET and GND.
4. Connect the driver and adjust CN-T to a position that does not count down even if the
driver is used to further tighten screws that have already been tightened.
5. Adjust WS-T to the time taken for the solenoid valve to operate after the work piece
arrives.
6. Adjust WR-T to the time taken to turn the solenoid valve OFF after all screws have been
tightened.
7. Connect a commercially available counter to the COMP signal and GND on the rear
panel terminal block to manage the total number of completed work pieces.
