The Facilities Panel includes eight general-purpose optically isolated digital output signals (in addition to those signals that are available at the Z-Axis IO Board). These lines are accessed in a single DB15 connector (Figure 34-161).
These output signals can be configured as "sinking" or "sourcing." As shipped from the factory, the output signals are configured as "sinking" (Figure 34-162), i.e. the external equipment must provide a 5 VDC to 24 VDC pull-up voltage on an output pin and the controller pulls this pin to ground when the signal is asserted as true. This configuration is compatible with "sourcing" (PNP) devices.
Alternately, the output signals can be configured as "sourcing" (Figure 34-163), i.e. the external equipment must pull-down an output pin to ground and the controller pulls this pin to 24 VDC when the signal is asserted as true. This configuration is compatible with "sinking" (NPN) devices.
Figure 34-163: Sourcing Output
Outputs can be individually configured as sinking or sourcing signals. To configure the output signals, the X-axis rear cover must be removed and jumpers on the Guidance Controller must be changed. For more information on configuring the jumpers, see the Guidance 3000/2000 Controllers User Manual.

| Electrical Shock | |
|
Improper electrical connection or connection to an improper electrical supply can result in electrical shock, burns, fire, and damage to the equipment and serious injury or death. The
Guidance 3400, the PrecisePower Intelligent Motor Power Supply,
and the 24 VDC power supply are all open frame electrical
devices that contain unshielded high voltage pins, components
and surfaces. In addition, the motor power supply provides
up to 320 VDC volts and takes about 2 minutes to bleed down
after power is disconnected

The pinout for the Digital Output Connector and the corresponding GPL signal numbers are described in Table 34-121.
| Pin | GPL Signal Number | Description |

Digital Output 1 - This output signal can drive 500 mA of current whereas Outputs 2-8 can only drive 100 mA. Due to this higher drive level, even when this output is off, a small amount of current leaks. This leakage can cause some devices that are connected to this signal to always indicate that this output is on. If this occurs, a small drainage resistor should be tied to this signal. |
