Initial Filling; Level Monitoring; Bleeding The System - Vogel KFA Instructions De Service

Initial filling

Which lubricants may be used with the units may
be seen from the current release list "Schmierstoffe
für Progressivanlagen"
at: www.vogelag.com
When the unit is filled for the first time, the lubricant
forces the follower upward until the overfill outlet
opens. As filling continues, the air escapes until
the entire reservoir is filled with lubricant. When
excess lubricant starts to emerge from the overfill
outlet, stop filling completely.
When topping up, take care not to let lubricant
emerge from the overfill outlet. Danger of accident
or environmental pollution!

2.7 Level monitoring

Visual
The transparent reservoir enables you to visually
monitor the level. The level should be checked at
regular intervals for safety reasons. The current
level can be precisely seen from the position of
the follower.
When the level in the reservoir has
dropped below the „min" marking, bleed
the entire system.
Level switch
Pump units of the KFA and KFAS series are
available with an automatic level control function
(see section 2.2).
KFAS: When the level drops below the „min"
marking, the sequence of operations is
stopped, and a fault message „FLL"
appears in the display.
KFA: The level signal is output via the
appropriate connector
(see sections 3.2, 4.2, 4.6).
Note!
Pump units with electrical level control are identified
by a „W" in the order description.

2.8 Bleeding the system

•
Disconnect the main lines from the unit. Operate
the pump until the lubricant emerging from the
pressure relief valve is free of bubbles.
Reconnect the main lines.
•
Disconnect the main line from the main
distributor. Operate the pump until the emerging
lubricant is free of bubbles. Reconnect the
main line.
•
Disconnect secondary lines from main distributor.
Operate the pump until bubble-free lubricant
emerges from all ports of the main distributor.
Reconnect the secondary lines.
•
Finally, bleed secondary lines, secondary
distributors, lubricant lines and lubrication points,
and check for proper functioning.
