System, components, and lines for trucks with Electronic Monitoring System (EMS)Typical Example (1) Lubrication pump (2) Autolube timer (3) Electric solenoid air valve
Illustration 3 g00291857
(3) Electric solenoid air valveThe electrical system for the automatic lubrication consists of two components. The two components are the autolube timer (2) and the electric solenoid air valve (3) . The timer energizes the solenoid at specific time intervals. The solenoid controls the air line which operates lubrication pump (1) .Ten minutes after the machine has started the timer will turn on the solenoid. The timer keeps the solenoid on for 75 seconds. Then, the timer is shut off. At every 60 minute interval, the timer will turn on the solenoid for 75 seconds. This timing interval continues until the machine is turned off.Trucks With Vital Information Management System (VIMS)

(4) Signal to the VIMS (5) Signal to the VIMS sensor module (6) VIMS sensor moduleThe electrical system that is for the automatic lubrication system has an electric solenoid air valve (3) . At specific intervals, the electric solenoid air valve is energized by the VIMS. The solenoid controls the air line which operates the lubrication pump.Ten minutes after the machine has started the VIMS will turn on the solenoid. The VIMS keeps the solenoid on for 75 seconds. Then, the solenoid is shut off. At every 60 minute interval, the VIMS will turn on the solenoid for 75 seconds. This timing interval continues until the machine is turned off.The time can be adjusted from 5 minutes to 120 minutes and the solenoid ON time can be adjusted from 30 seconds to 120 seconds. The time is only adjustable with the VIMS. Refer to the Service Manual, "Vital Information Management System".
