LC-1000 Lube System Controller
Sample LC-1000 Program for Piston Distributor or Injector Systems
31 Point Piston Distributor System
DESCRIPTION
System Lube Volume: 99 cc (6.0 cu in) per hour
EO-3 Motor Driven Pump: 140 cc/min (8.5 cu in)
Total Piston Distributor Displacement: 4.62 cc/cycle
(.28 cu in)
Cycle Interval: 99 cc / 4.62 cc = 21.4 cycles/hr
60 min/21.4 cyc = 2.8 min (168 sec) per cycle
Cycle Switch (Pressure Switch) Transitions:
(1 transition/cycle) x 1 = 1
Pump Run Time: 4.62cc/140cc = .033min
(1.98 second)
Monitor Time: 1.98 sec x 2 (safety factor) = 3.96
seconds
Note: Due to the very short calculated pump run time,
use a 20 second monitor time.
