	6712FR Refrigerated Sampler
	Section 5 Extended Programming
5.13 Sampler Enable	In addition to programming enable conditions, extended pro-
Responses	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	For certain monitoring programs, you may want the sampler to
Enabled	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.
	ONCE ENABLED,
	STAY ENABLED?
	YES NO

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.

5.13.3Sample at Enable or You have the option of directing the sampler to take a sample as

Disable	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.
	SAMPLE AT ENABLE?
	YES NO
