lube-line check valve or point of lubrication. The "NFS-4", "NFS-5" and "NFS-9"
No-Flow switches for Ajax are provided with brackets for mounting to one of
the screws which hold the cast cover to the cylinder near the cylinder check.
Connect No-Flow switch contact wire to magneto or alarm/shutdown switch.
3. Connect line from lubricator to inlet port on No-Flow switch.
4. Hand pump lubricator until oil flows from outlet port; then connect line from
outlet to point of lubrication.
5. Switch is factory adjusted for a shutdown time of approximately 3 minutes
using SAE 30 oil at 100 º F. The switch is viscosity sensitive, therefore,
shutdown time will vary with oil viscosity. Switch can be field adjusted for a
shutdown time between 2-8 minutes.
6. If adjustments are necessary, ensure that adjustments are made while engine
/ compressor / No-Flow switch are at their normal operating conditions. The
adjustment setscrew is located on bottom of switch housing. Turn setscrew
IN to decrease shutdown time and OUT to increase shutdown time. Shutdown
time can be determined by removing/disabling lubricator pumping unit. On
multiple pump installations pumping at the same rate, the setting can usually
be transferred from one switch to another by making the distance from
the end of the adjustment setscrew to the end of the adjustment setscrew
housing equal on all
