The solenoid energised Oil Injection Unit with up to 4 nozzles,
directed at the frictional points (e.g chain link pins) is activated
by means of a signal received from a proximity switch. Once
the Unit operates, an impulse is relayed to a Control Unit.
The Control unit will be programmed to receive the total number
of impulses required to lubricate the entire chain, i.e. the
total number of links, before a rest period is initiated. Ideal
for Conveyor chains.
