5.3.3 Operate from external signal (setpoint sample)
The setpoint sample option starts and stops the sampler after

The current status indicates when the sample program is being
inhibited by an external device.
Note: Setpoint and stormwater sampling cannot be enabled at the
same time.

active and stops the program when the signal is no longer
active.
Note: SETPT CONTROL cannot be set unless a setpoint trigger is
enabled.

before the sample program starts. The delay time will begin
when the external signal is received. The program will begin
