LEMCOM VACUUM PUMP SETTINGS
This chapter describes all the settings that can be configured individually on each LEMCOM module
(master or secondary). Configuration can be done using LEMCOM Manager (PC software),
LEMCOM Web Server and by sending configuration data via EtherNet/IP.
SETTING
DESCRIPTION
COMMENT
L1
Gripped product threshold
Vacuum threshold that enables the
"Gripped product" signal.
Default unit: percent vacuum (0 to 99%)
Other units (inHg / mbar) available from
LEMCOM Manager and LEMCOM Web
Server.
h1
Hysteresis of gripping threshold
Vacuum drop that disables the "Gripped
product" signal.
L2
ASC Regulation threshold
Vacuum threshold that automatically
disables the vacuum generation (ASC
regulation system).
h2
Hysteresis of ASC regulation threshold
Vacuum drop that restarts vacuum
generation.
AUTO BLOW
Automatic blow off function
AUTO BLOW
duration (ms)
Automatic blowing for a period of 1 to
9999ms.
Automatic blow off starts as soon as
vacuum control is disabled.
ASC
Vacuum regulation system (Air Saving
Control)
Compressed air savings of 60 to 99%.
Regulation threshold is defined with L2
parameter.
DIAG/E
Regulation system monitoring (DIAG
ECO)
DIAG ECO avoids repetitive bounces of
the regulation system in case of vacuum
leakage (porous handled product).
LEMCOM automatically switches to
permanent vacuum once the vacuum
valve bounces more than "
Maximum
bounces No
." during a period of "
DIAG/E
analysis time
".
Maximum
bounces
Number
Maximum bounces of the regulation
system before enabling permanent
vacuum.
DIAG/E
analysis time
(s)
Analysis period for counting bounces of
the regulation system.
Customer LED
Configurable blue LED
Define the operating mode of the blue
LED located on the front side of the
LEMCOM.
Refer to
§4.1
to get the description of blue
led modes.
Valves status
Status of the vacuum pump valves in
case of communication loss
Security setting that defines the status of
the vacuum and blow-off valves when
fieldbus (master module) or local bus
(secondary modules) communication is
lost.
MD1 (0x00)
Hold the valves in the
states they were before communication
loss
MD2 (0x01)
Vacuum command
enabled / blow-off command disabled
MD3 (0x02)
Vacuum command
disabled / blow-off command enabled
MD4 (0x03)
Vacuum and blow-off
commands disabled
MD5 (0x04)
Vacuum disabled then
blow-off for 2s then vacuum and blow-off
disabled
