6. Pulse Out: This output sends a pulse to an optional recording or
monitoring device each time the pump starts, allowing the time of the
sample event to be recorded. Refer to the Specifications section for
details about the output pulse.
7. Status: This red LED indicates the status of the sampler. While the
sampler is waiting to be triggered, the light remains off. Once
triggered, the LED will blink once every two seconds while the Delay
or Interval timers are running and while the pump is operating. The
LED remains lit constantly when the sample bottle is full or if the
bottle switch is not plugged in.
8. Power: This turns the power to the sampler on and off. Turning the
switch off for one second resets all functions and timers.
9. Charger: Connect the battery charger here.
10. Water Sensor: When an optional water sensor is plugged into this
jack, sampling will not begin until the presence of water is detected
(the Rain Sensor must also detect water). If this sensor input is not
being used, plug one of the two shorting plugs supplied with the
sampler into this jack. This input has no affect when triggering the
sampler using the Trigger Input in External Trigger mode.
11. Rain Sensor: When an optional water sensor is plugged into this
jack, sampling will not begin until the presence of water is detected,
usually in a rain gauge (the Water Sensor must also detect water). If
this sensor input is not being used, plug one of the two shorting
plugs supplied with the sampler into this jack. This input has no
affect when triggering the sampler using the Trigger Input in External
Trigger mode. This input can also be used to take individual
composite samples and is described in detail later in the section
titled “External Trigger Mode”.
12. Bottle Switch: The sample bottle float switch plugs into the control
panel here. For sampling to occur a float switch must be plugged in
and the bottle must not be full. If the Status LED remains lit all the
time, check this connection.
13. Test Pump: Pressing this button tests the operation of the pump.
This button will run the pump regardless of whether the bottle switch
is plugged in or not. The pump runs forward for as long as the
button is held down, then reverses for an equal amount of time or 15
seconds, which ever is less.
