14/54 Function
6 Function
The lubrication unit LU 2 has two operating modes:
• TIME mode
• PULSE mode
A special delivery volume (PURGE) can also be triggered and the operation of
the lubrication unit can also be disabled using a 2-digit PIN number.
The device is equipped with counter pressure and lower temperature monitoring.
Device settings are retained even after a power failure by the use of an integrated
backup battery.
6.1 TIME mode
A metering period (per month, 1 to 12 months) can be entered in the TIME mode.
During this metering period metered volumes of lubricant are delivered at fi xed,
regular intervals (interval period 't [h:mm]). The volume of metered lubricant
delivered is determined by the metering period, the interval period and the entered
oil container LC 2.
Please note:
(1 cm³ | 0.9 g lubricant)
358 814-25
Only in TIME mode: At the initial startup the drive runs for approximately 8 sec
after the supply voltage is connected to prime the lubrication unit.
The operation then starts with the fi rst interval time. When the interval time
has expired the metered volume is delivered.
• The operating mode, the entered delivery period, the entered oil container LC 2
(Ö LC250) and the metered volume to be delivered per 100 hours are shown on
the display.
• Metered lubricant deliveries are only executed when the supply voltage is connected.
• Metered lubricant deliveries not executed because of a fault are automatically
rescheduled at half the interval time.
