Graco LC-1000 specifications Cycle Pressure Switch Transitions

LC-1000 Lube System Controller 14540

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.
