5.13 Sampler Enable
Responses
In addition to programming enable conditions, extended pro-
gramming lets you control the sampler’s response to its enable
state. You can:
• Stay enabled after the first enable.
• Set up a repeatable enable.
• Take a sample at enable or disable.
• Delay the start of sampling after the enable.
• Reset the sampling interval countdown each time the
sampler is enabled.
• Control the sampling interval countdown while
disabled.
• Enable Part B of a two-part program when Part A is
done.
5.13.1 Once Enabled Stay
Enabled
For certain monitoring programs, you may want the sampler to
continue to sample, even though the conditions that enabled the
sampler no longer exist. When you use the ONCE ENABLED,
STAY ENABLED feature, after becoming enabled the sampler
takes samples until it reaches the end of its program.
Note
The STAY ENABLED feature works only when the sampler
becomes enabled following program start. If you need this fea-
ture with enable prior to program start, contact Teledyne Isco
for details.
5.13.2 Repeatable Enable After enabling the sampler, the enabling instrument (or instru-
ments) continues to monitor the conditions and disables the
sampler when the conditions are no longer satisfied. If
re-enabled, the sampler resumes the sampling program.
Note
Repeatable enable is called “sampler latching” in flow meters,
flow loggers, and FLOWLINK. Latching a sampler produces
the same results as selecting YES; the difference is that the
external instrument controls the latching.
5.13.3 Sample at Enable or
Disable
You have the option of directing the sampler to take a sample as
soon as it receives the enable and/or disable signal. If you
program the sampler to stay enabled and choose to take a sample
at enable, the sample interval will be reset at the enable time.
Samples at disable do not affect the sample intervals. Standard
programs do not take a sample at the enable time.
