Automatic Lubrication System - Section 42 OM4202 Page 42-8 24 VDC Solid State Timer Adjustment The timer is factory set for a nominal 2.5 minute (off time) interval. Dwell time is approximately 1 minute, 15 seconds. A longer interval (off time) is obtained by turning selector knob (3, Figure 42-3) to the desired time interval. The injectors may be adjusted to supply from 0.13 cc to 1.31 cc (0.008 in 3 to 0.08 in 3 ) of lubricant per injec- tion cycle. The injector piston travel distance deter- mines the amount of lubricant supplied. This travel is in turn controlled by an adjusting screw in the top of the injector housing.
Injector Adjustment Turn the adjusting screw (2, Figure 42-4) counter- clockwise to increase lubricant amount delivered and clockwise to decrease the lubricant amount. FIGURE 42-3. TIMER ADJUSTMENT NOTE: Set the timer by turning selector knob (3) to the 2.5 minute setting point. Then, turn the selector knob clockwise, one detent at a time, to the desired setting, or until the maximum limit of eighty minutes is reached. The recommended setting is 20 minutes. ! CAUTION! The solid state timer is a sealed unit, do not attempt disassembly. FIGURE 42-4. TYPE SL-1 SERIES INJECTOR Injectors (SL-1) 1. Visible Indicator Stem 2. Adjusting Screw 3. Outlet - 0.125 in. NPT 4.
Manifold Each lube injector services only one grease point. Injectors are available in banks of two, three, four and five as well as single replacement units. Injector output is adjustable: With the solid state timer set at 20 minutes, the rec- ommended setting is: Maximum output = 1.31 cc (0.08 in 3 ). Minimum output = 0.13 cc (0.008 in 3 ). In case of a pump malfunction, each injector is equipped with a covered grease fitting to allow the use of external lubricating equipment. Four turns clockwise from the maximum coun- terclockwise position. This delivers approxi- mately 0.66 cc (0.04 in 3 ) of lube per cycle.
