3.5.3 Minimum and maximum level indicators for grease/oil
3.5.3.1 Laser for grease minimum level (optional)
The minimum level is achieved by a laser probe. The probe is normally closed when there is grease.
When the minimum level is reached, the probe signals the lack of lubricant.
For connections and setting see Par. 6.1.1 and 6.1.2.
3.5.3.2 Floating switch minimum/maximum level sensor for oil
A dipstick probe with dual floating switch mounted on the pump cover allows the minimum oil level
(reserve) and the maximum level (that allows the interruption of automatic reservoir filling) to be
read.
For connections, see Par. 6.1.3.
3.5.3.3 Floating switch visual maximum level for grease/oil
The filling phase of the lubricant in the reservoir is carried out by the operator with an appropriate
pump.
Once the maximum level of lubricant is reached, the rod that indicates that the reservoir is full
intervenes.
3.5.4 Grease and oil stirring paddle (standard execution)
Two reservoirs have been provided with capacity of 10, 30 and 100 kg. (22-66 – 220 lbs).
As standard, the reservoirs have the stirring paddle and the scraper that do not need to be
disassembled in the event of disassembly and replacement of the same. As standard equipment,
under the stirring paddle there is an electrogalvanized steel mesh with 0.5 mm (0.02 in.) holes. There
pump is thereby protected from any foreign objects that could be inadvertently present during the
reservoir filling phase.
3.6 Electrical equipment
“DROPSA” electrical equipment is designed for the purpose of providing a system complete with all
the controls needed for operation of centralized lubrication systems that is automatic and controlled
by safety signals. The primary supply voltage is 400 Vac and 50 Hz. Other voltages are available on
request. For more information on the available version, contact the DropsA sales engineers.
