Timer Operation
General Operation of the Lubecore™ Truck Timer
The following is a functional description of the Lubecore™ ALS
truck timer. This information pertains to model 12.016 and
12.036.
For a description of the Lubecore ALS for trailer application
please see the appropriate documentation.
The 10-30 VDC Truck Timer has been designed with the capability
to operate a variety of the Lubecore and competitor lubrication
systems, pneumatic and electric. Choose the appropriate harness
assembly to adapt to specific applications.
Upon ignition, a programmed interval is initiated (“pause phase”). Each time the ignition is
switched on or off, the timer stores the current status and resumes that status after the ignition
is turned on again. After the pause phase is concluded, the timer engages either a solenoid or
an electric motor, starting the “working phase”. If the system has been equipped with a
Lubecore Smart Switch, the light will be illuminated during working phase until the pressure
switch is closed. Depending on the size of the lubrication system, this may take a few seconds.
The working phase will last for a programmed period of time. After 2/3 of the working phase has
been completed, the program checks for feedback from the pressure switch.
After a sufficient lubricant pressure has been reached within the ALS mainline section, the
pressure switch closes to ensure correct lubrication and the light in the Smart Switch will turn
off. If the switch does not close, an audible and visual alarm is activated for the remainder of the
working phase. The alarm will continue through subsequent lubrication cycles until the problem
has been corrected.
The timer is equipped with real-time clock. This clock, synchronized during programming with a
computer, registers all completed cycles, total running time, errors and more. See the timer
report section for more details. Any pressure failures are recorded with a date and time stamp
both when it occurred and was resolved.
To prevent air from entering the lubrication system, Lubecore automated lubrication systems
can be equipped with a low-level switch. Once the follower plate triggers the low-level switch in
the reservoir, the timer will prevent the pump from cycling and activate the externally mounted
light which will illuminate and blink (2 seconds on, 2 seconds off) until the lubrication cycle is
complete. A low-level condition triggers a15 second audible alarm and a blinking light
commence at the initial turn of the ignition. The light will only blink for every proceeding alarm
with the same constant supply of ignition power.
As long as the reservoir is below minimum level, the timer will count pause times and cycles, but
will NOT perform a lubrication cycle. The alarm light will indicate to the operator that the
reservoir is below minimum level during the cycle phase.
Note: Once the reservoir has been refilled, the timer will continue to flash a warning until the
timer completes one fully automated cycle. It will then return to its normal programmed
operations.
Low level events are permanently stored in the timer memory with a date and time stamp from
the real-time clock. This function is not available on the (12.057, 12.058 & 12.059) timers.
