Figure 2. TEACH Interface
Two TEACH methods may be used to program the sensor:
• Teach individual minimum and maximum limits, or
• Use Auto-Window feature to center a sensing window around the taught position.
The sensor may be programmed either via its push button, or via a remote switch.
Remote programming also may be used to disable the push button, preventing
unauthorized personnel from adjusting the programming settings. To access this
feature, connect the gray wire of the sensor to 0 - 2V dc, with a remote programming
switch between the sensor and the voltage.
NOTE: The impedance of the Remote Teach input is 12 kΩ.
Programming is accomplished by following the sequence of input pulses (see
programming procedures starting on page 4). The duration of each pulse
(corresponding to a push button “click”), and the period between multiple pulses, are
defined as “T”:
