Board Sit
An optional Board Sit signal can be used to verify that the board is sitting
flat on the support plate. Dry contact sensors are recommended for this.
Connect the micro switches in series, and connect them to the fixture
connector provided, as shown in
Figure 3- 11 . Use Pin 2 and 3 for dry
contact (voltage free).
When the board is sitting flat on the support plate, all the switches close
and provide a short signal to the PLC input. Once the signal is detected,
the Press is lowered to the All Probes position.
