INITIAL START-UP / COMMISSIONING CHECKLIST
FLOW SWITCH SETTING / ADJUSTMENT (“NO FLOW ALARM”)
Note: Flow switch needs to be adjusted to actual flow rate for proper system operation.
Please make sure system is properly primed and check when pump running for a steady stream of fuel
without air bubbles in the mechanical flow meter (indicator) inside the STS 7030 enclosure. If the “NO
FLOW ALARM” alarm light is blinking (and after 10 seconds illuminate continuously as the pump is turned
off) the
flow switch located on the side of the mechanical flow meter needs to be adjusted to the
actual flow rate .
This can be easily done by sliding the black switch (with lead attached) located on the side of the sight
glass carefully up or down (while pump is running) and lining up the flow switch with the indicator ring
inside the sight tube of the flow meter showing the actual flow rate. For further information please see
enclosed instruction sheet.
You can reset the alarm by pushing the “ALARM RESET” button located on the control panel.
GAUGE VENTING / ACCURACY
After shipment, pointer of gauges may not rest at zero due to internal case pressure buildup caused by
temperature variations.
Accuracy may be significantly reduced . To restore gauge to operating
condition, move yellow lever of fill plug to the ”open” position or remove small plug from top of
gauge and leave open .
INITIAL TEST PROCEDURE
o
With breakers and power turned on and pump running check all alarms for proper operation:
1.
Manually raise float switch located in drip/spill tray. Pump should immediately turn off and “LEAK
DETECTION” should illuminate. Reset alarm by pushing the “RESET ALARM” button on the control
panel.
2. Slowly partially close inlet ball valve. At 12”HG pump should turn off and “HIGH VACUUM ALARM”
should illuminate. Open inlet ball valve again. Reset alarm by pushing the “RESET ALARM” button.
3. Slide the flow switch located on the side of the mechanical flow meter slightly upwards away
from the flow indicator inside the sight tube (mark original position before doing so). The “NO
FLOW ALARM” indicator should start blinking for 10 seconds and then illuminate constantly as the
pump is turned off. Slide flow switch back into original position and reset alarm by pushing the
“RESET ALARM” button.
Note: If any of the above described alarm test procedures fail or if any alarm trip value
deviates immediately contact AXI International.
