Input and output signals - time control
LUB-V can be switched off completely by switching off the supply voltage. Its settings will
not be lost: the integrated microelectronics automatically store the remaining time until
the next scheduled lubrication cycle. After reapplying the supply voltage LUB-V automati-
cally checks itself and continues to operate according to the set values.
After a long standstill of LUB-V a "quick check" is recommended (chapter 6.3.6).
The output signal at PIN 4 can be tapped for further processing (e.g. indicator light or
external control). The maximum permissible current output must not exceed I
max
< 20mA.
No inductive load (e.g. relay) may be connected!

LUB-V operates in hour mode -h- as a time-based and cycle-controlled lubrication system
according to the values set in PRO menu.
