and continue sampling 24 VDC maximum at 100 mA
load maximum
Red E Event input Signal sent to the instrument when
a sample has been collected
—
Green F Bottle number input Signal sent to the instrument that
identifies the sample bottle
—
Connect to sensors
Connect a maximum of three sensors to the instrument with quick-connect sensor cables or bare-
lead sensor cables. Refer to
Table 5 – Table 8 for wiring information.
When the sensor cable will go through conduit, use conduit that is 1-inch or larger, a bare-lead
sensor cable and a junction box. Refer to
Connect a submerged area/velocity bare-lead sensor cable
to a junction box on page 13 or Connect an ultrasonic bare-lead sensor cable to a junction box
on page 15.
Note: Do not cut or splice a sensor cable because instrument malfunction can occur and make the warranty void.
