A two position DIP switch between the two main connectors, is visible from the connector edge

of the unit. These switches are for future expansion and currently have not effect on the

operation of the unit.

OUTPUTS

The PD100 outputs include a form C relay for reporting OUT conditions and a dc logic output for

reporting no metal within sensing range of the probe.

The logic output is labeled METAL since it provides an indication that the metal target is within

sensing range. The intent of this output is to proximity of the target though it may be outside the

calibrated accept zone. This output provides a dc sourcing signal that switches between zero

volts and 22 volts, delivering up to 100 mA.

The METAL output is ON (sourcing at 22 volts) when material is within sensing range of the

probe.

INDICATORS

The function of the indicators and controls on the PD100 are described in the following

paragraphs:

1. The amber OUT indicator is ON whenever the target is beyond the position threshold

established during calibration.

2. The green OK indicator is ON whenever the target is at or inside the position threshold as

established during calibration.

Through various flashing patterns, these indicators also provide information regarding system

mode (calibrate vs operate), firmware version number, and error conditions. Reading firmware

version is described later in this document. All other flash patterns can be interpreted as follows:

Alternate flashing of amber and green indicates busy such as during initialization after power-up.

Simultaneous flashing of amber and green indicates failed calibration. This error can occur if the

gap between the probe and the target is excessive at calibration.

Green flashing, amber off - calibration in process.

Green flashing, amber on - probe error. Probe may not be connected, probe wire broken, or

probe may be defective.
