Description:
The FP4 D is properly connected to an external controller via the electrical interface
and connected to the power supply.
The FP4 D sends a permanent output signal (high level) to PIN 4, which indicates to
the external control (PLC) that it is ready for operation. This output signal must be per-
manently and continuously present for >3 seconds. Control by the external controller is
only possible if this condition is present.
The control signal 2 seconds with a signal length of 12 (11.9 ... 12.1) seconds high
level can be sent from the external control (PLC) to the FP4 D.
Immediately after the control signal drops, the motor run (ML) of the FP4 D starts and
0.16 cm³ lubricant is conveyed to the outlet. Simultaneously with the start of the motor
run (ML), the FP4 D sends a low level output signal to the external controller (PLC) as
confirmation for the duration of the motor run (ML).
The motor running time (ML) depends on various conditions, including the counter-
pressure present or built up in the hydraulic system and the temperature. With the FP4
D, the motor running time (ML) is 7...17 seconds.
At the end of each error-free and successful motor run (ML), the output signal at the
FP4 D changes from a low level to a high level for a short pause time P = 2 seconds.
A total of 40 engine runs and donations will take place immediately one after the
other. 40 x 0.16 cm³ = 6.4 cm³ lubricant is conveyed from the cartridge to the outlet.
A possible next control signal can be sent from the external controller (PLC) at the
earliest >3 seconds after the end of the error-free and successful motor run. In the
meantime, the FP4 D does not process any control signals.
In order to ensure a reliable and unambiguous recognition of the control signal, a
pause must be observed. For the control signal 12 seconds, the FP4 D has a pause
time (Tp) between two identical or different control signals of at least 733 (Tp=ML
max
x
40 s P x 39 + signal 3 seconds) seconds.
For an FP4 D with two pump units, 40 filling strokes
per pump unit
are triggered
when the control signal is triggered for 12 seconds. The pause time (Tp) is increases to
1553 seconds.
If the integrated microelectronics of the FP4 D has detected an error during or im-
mediately after the end of the motor run (ML), it is transmitted to the external controller
(PLC) by the corresponding output signal (section 8.3).
