Set-Up and Controls

Powering On the A-100NA

The A-100NA is powered on when plugged into the power source.  The pump is now ready to be run manually by switching on the Power Switch. 

Controls

The A-100NA has only a dial knob to control the speed (output) of the pump.  Adjust the knob to change the percent cycle time on/off.   

The pumping mechanism is turned on and off by an electronic cycle timer. The total-time cycle is factory preset and is not user adjustable. The on-time cycle is adjustable from 5% to 100% of the total cycle time (A-100NA timer adjusts from .3 to 60 seconds with total time cycle of 60 seconds).  

Example: If the total-time cycle is 60 seconds and the on-time cycle is adjusted for 25 percent, the pump will run for 15 seconds and turn off for 45 seconds (60 second total cycle). This cycle is repeated until either the power switch is turned off, the cycle time is changed, or the input power is disconnected from the pump.  

To adjust the pump output – 

• Slide the slide clamps to the left only far enough to open the control panel door.  
• Turn the adjustment knob to the desired percentage of on-time per cycle.  

Note: When power is applied to the pump, the A-100N will either automatically begin to pump, or maintain power-off status, depending on the power switch status 

Flow Verification System (FVS) – sensor sold separately 

The A-100NA is equipped with a Flow Verification System which is designed to stop the pump and provide a contact closure output in the event the sensor does not detect chemical during pump operation. (This could indicate a clogged injection fitting, empty chemical solution tank, worn pump tube, loose tubing connection, etc.) 

To allow the pump to clear any gasses that may have accumulated during stopped operation (such as with chlorine), an alarm delay time value from 1- 256 seconds must be programmed.  
Press the FIELD and DIGIT buttons at the same time to enter the delay value.  
Note: an alarm delay value of 000 disables the FVS system. Any other value (001-256) activates the FVS.  
The pump will stop, and the alarm mode activated, if no pulses are received by the pump and the alarm delay time period has ended.  
Press the STAND-BY button twice to clear the alarm and restart the pump. The Flow Verification Sensor is sold as an optional accessory. 

Ensure the flow sensor used is operated within its operating flow range. Flows that fall outside of the sensors range will create a false no-flow alarm.
