Empty level The empty cartridge level is indicated by a 0,5-Hz square wave signal
(LOW-HIGH level).
Once the empty level has been reached, the lubricator will cease to
deliver lubricant or process any more control signals. This ensures
that no air can enter the lubricator or lubricant lines.
The empty level signal cannot be cleared and continues without
interruption until the cartridge is replaced.
The transition across the output signals when replacing a cartridge
with the lubricator switched on is illustrated as follows,
