Trip Speed Test Procedure
After following Trip Speed Programming Procedure, system must be tested to ensure Trip Speed was programmed
correctly. Entering TEST Mode causes system to trip at ‘Input Speed’ from Programming Procedure – raising engine
speed to actual ‘Trip Speed’ is unsafe and unnecessary.
Before Testing:
o
IF valve is synchronized with shut-off system on same engine:
Leave all controllers connected to ensure engine shuts down
o
IF valve is synchronized with shut-off system on secondary engine:
Disconnect secondary controller to prevent accidental shut-down of secondary engine
1.
Ensure fuse is removed from F1 on Mode Selection Box
2.
With engine off, push switch to close valve and hold switch for 5 seconds until light begins flashing rapidly
3.
Release switch to re-open valve. Light will exhibit continuous rapid flash interrupted by single pulse*
4.
Start engine and slowly raise engine speed to ‘Input Speed’ as previously recorded
5.
Valve will close and red light will illuminate until valve resets itself to open (In Manual Reset Mode, light will stay
illuminated until valve is manually reset by pushing toggle switch)
6.
If valve did not close when expected, trip speed may not be correctly programmed. Confirm installation and re-
follow steps indicated on previous page
*Light will exhibit ‘double pulse’ if Secondary Trip Speed is active
