L50 Injection Lubricator - Parker

Installation (cont'd):
Injection Lubricator Options
Pulse Generator:
In those applications where the maximum amount
of oil delivery is not enough, or flow is continuous,
the L50 is available with an optional Pulse Generator
(“G” option). The pulse generator fires the injector
module at the start of each cycle, and then at specified
intervals (adjustable between 1 sec. and 20 sec.)
within the cycle. The unit will not fire if the tool is not in
use. The Pulse Generator assembly may be ordered
separately as RKL50G.

Injection Lubricator Troubleshooting
1.) Injector actuates when tool/equipment is activated,
but no oil is dispensed.
2.) Injector module does not actuate when tool/
equipment is activated.
3.) Air leaks constantly from grooves in sensor body
under the injector module.
4.) Air and/or oil leaks from top or bottom of injector
module, cycle counter, or pulse generator.
5.) Cycle counter does not make injector fire at the
pre-determined 12, 24, 48, 96 or 192 cycle count.
6.) Cycle counter allows injector to fire all the time (or
more than it should).
7.) Pulse generator not timing consistently.
Cycle Counter:
For those applications where the minimum oil delivery
per cycle is too much, the L50 is available with an
optional cycle counter. Located below the injector
module, it counts the number of equipment cycles.
With a counter installed, the injectors will not fire until
the counter has reached the desired number of cycles.
Cycle Counter Adjustment:
The cycle counter has four positions:
Off: Oil injector module will not operate
1: Oil Injector module operates with every cycle
5: Oil injector module operates every fifth cycle
10: Oil injector module operates every tenth cycle
Push switch to desired
setting for lube injection
every 1, 5, or 10 tool cycles.

Problem Probable Cause
Check to make sure oil supply is adequate and that
injector has been properly primed and purged of all air
in oil supply (see priming instructions).
The minimum airflow through the lubricator must be at
least 5 SCFM or injector module will not fire.
This is generally caused by foreign material being
caught in the flow sensor piston bore in the sensor
body preventing it from closing.
O-ring seals are either cut or misaligned or two Phillips
head screws holding the top-plate are loose.
The two Phillips head screws holding the top-plate
are over-torqued (should be 30-40 in. lbs.) or internal
counter problem.
The two Phillips head screws holding the top plate are
under-torqued (should be 30-40 in. lbs.) or internal
counter problem.
The air logic timer has become contaminated with
either liquid or particulate matter.
