itself and the Rain Sensor goes dry.  The next time the sensor detects moisture, the Start 

Delay timer will start over again and another sample will be taken when it expires. 

 

If the pump’s Sample Size control is set to take a full-bottle discrete sample, further triggers 

will have no affect.  If the pump is set to take composite samples, each one will represent 

the conditions at the time of that “qualified rain event”.  This process will continue until the 

sample bottle is full and the Status LED remains lit all the time. 

 

Using the Trigger Input as a source: 

This input is generally used for connecting to a flow monitor, processor controller, or other 

external monitoring device. 

 

When using the Trigger In input jack, leave the Rain Sensor input jack disconnected.   

 

Upon being triggered by the Trigger Input, the Start Delay timer begins running.  When the 

delay timer has expired, the pump takes a sample based on the Sample Size setting.  

Holding the Trigger Input active past the end of the sample will cause the pump to continue 

until the Trigger Input is released.  When the sample is complete, the pump reverses, then 

stops. 

 

Flow Proportional Sampling 

 

a.

 

To set the WS700R up to take flow proportional samples, a flow monitor must 

be attached to the control panel.  In this configuration, the sampler is 

designed to take a sample every time a specific amount of flow has passed 

through the flow monitor. 

 

b.

 

The flow monitor must provide a momentary switch closure (250ms or longer) 

or a pulse of 4-30VDC, whenever a sample is to be taken.  The output of the 

flow monitor must be wired to a 2-wire RCA jack as shown in Appendix C.  

The phone plug is then inserted into the Trigger In jack on the control panel.   

 

c.

 

Set the Sample Interval knob to External Trigger mode and the Sample Size 

knob to the desired sample size.  The sample will be taken, flow 

proportionally, as directed by the flow meter.
