System Components
1. Controls
Timer
8852A
The timer is the “brain” of the automatic lube system. It requires a constant 24 volt power supply. Its function is to
supply and remove power from the pump module via a solenoid valve, at predetermined time intervals. The timer
must be programmed for “pump on” and “pause interval” settings.
Solenoid valve
9008A
The solenoid valve is controlled by the timer. The function of the solenoid valve is to turn the power supply on for
the pump module. The solenoid operates on a 24 volt signal received from the timer. The solenoid also has a
manual override button to activate the pump module.
Pressure switch (optional)
9146A
A pressure switch can be installed in an automatic lube system for additional system control and safety. A normally
open pressure switch when properly connected to the timer and installed so that it monitors supply line pressure will
turn the pump module off upon detection of a preset pressure, normally 2500 psi (172 bar, 17 MPa). Two advan-
tages of a pressure switch are:
It can monitor system for faults.
It can turn the power supply to the pump off when a preset pressure has been reached.
