* Do not apply power to these Pins.
Secondary Outut, Density or Temperature (Pin 13 and Pin 10)
Pin 13 indicates the density or temperature, represented by a 4-20 mA
or 0-5 Vdc signal, proportional to density or temperature. The current
and voltage signals are returned via Pin 10. Maximum series resistance
on Pin 3 is 500 ohms when configured for 4-20 mA. Recommended
load on Pin 13 is >100K ohms when configured for 0-5 Vdc. Do not
apply power to Pin 13.
Note: Not all models have a secondary output.
Alarm Output (Pin 3 and Pin 9)
Pin 3 indicates an alarm condition as an open drain FET configuration.
Maximum voltage is 30 Vdc, maximum current is 100 mA.
(See Figure 2-6 on page 2-8.)

When wiring terminal block in IP66 device, ensure wires are
appropriate length and are properly dressed. Unnecessarily long
wires can protrude below the top housing and cause damage to the
sensor assembly below.
