Low Level Switch & Sensor
The Lubecore ALS pneumatic pump can be equipped with a
low-level switch/sensor. The low-level switch/sensor can be
found on the right side of the pneumatic pump, just below
the reservoir. Once the follower plate reaches the minimum
reservoir grease level, the low-level switch/sensor opens.
The timer then alerts the operator that the reservoir is empty
and requires refilling. As long as the low-level switch is
engaged, the lubrication system will NOT be activated by the
timer. The timer does however keep a record of how many
grease cycles have been missed. This information is
accessible via the dongle timer interface. This function is
only available on the 12.016 and 12.036 model timers.
The operator is informed of a reservoir low level by an
intermittent (2 seconds on / 2 seconds off) green LED light in
the Smart Switch. This alarm lasts for the full duration of the
programmed interval time (working phase).
Note 1: In case of low lubricant level, filling the reservoir will automatically resolve the
error and normal operation continues. However, after filling the reservoir the led will
switch off after completing a normal lubrication cycle. (Test cycle will not reset the LED.)
Note 2: Depending on the size of reservoir, model of follower plate and type of timer
installed, model and type of low-level switch sensor may vary.
Note 3: Do NOT use a sensor type low level with the 12.016 and 12.036 timers.
Note 4: Do NOT use a mechanical type low level switch with a trailer timer.
