Table 5 AS950 sampler wiring (auxiliary half cable 8528500/8528501) (continued)
Connection Color Signal Description
BLK INHIB Black Inhibit/Start Auxiliary control input —Start a sampler after the sampling
program on another sampler ends. As an alternative, start a
sampler when a trigger condition occurs. For example, when
a high or low pH condition occurs, the sampling program
starts.
Liquid level input —Start or continue the sampling program.
A simple float level switch can supply input.
RED EVENT Red Sample event/Special
output
This output goes from 0 to +12 VDC with respect to Terminal
1 after each sample cycle. Refer to the Mode setting of the
hardware settings for the AUX I/O port. Refer to the
AS950 operations documentation.
GRN PRG Green Program
complete/Bottle
Typical state: open circuit. This output stays at ground level
until the sampling program starts again.
Use this output to start another sampler or to signal an
operator or data logger at the end of the sampling program.
— Bare wire Shield (terminated in
AS950 Sampler)
The shield is a connection to earth ground when AC power is
supplied to a sampler to control RF emissions and
susceptibility to RF emissions.
