External Speed Limit (RS)
This function can be used to temporarily limit the
lower and upper speed of the drive motor, e.g. if
it necessary to limit the maximum delivered air
quantity/power consumption.
Configuring the function "External Speed
Limit" (RPM Limit)
1
Set the desired min/max values in the "Settings
/ Configuration" menu.
2 Allocate an input to this function. See chapter
"Input programming".
As soon as the input is connected, the drive motor
speed only moves within the desired band.
Override Timer Start
If the compressor has been switched off because
of settings in the menu "Timer Start/Stop" (see
chapter "Timer control operation"), this function
will override the timer and start the compressor as
long as the input is activated.
For example, this allows the compressor to be
started by maintenance personnel during a week-
end when the timer would normally have shut
down the compressor.
Pressure Band p2
This function switches the pressure band to pres-
sure band p2.
If this function is active, the menu "Home" (field
"Current Pressure Band") indicates that the pres-
sure band p2 is being used and has been acti-
vated by a programmable input. The programma-
ble input number is also displayed.
Enable Sensor B1
Ex works, the signal for switching the compressor
between on-load and off-load is generated by the
compressed air line pressure sensor B1.
An open input will unload the compressor.
If the input is connected, the sensor controls com-
pressor switching between on-load and off-load.
Enable Remote Load (FS)
If the input is connected, on-load/off-load control
takes place solely via the "Remote Load" function
described below.
Remote Load (FS)
The Remote Load and Off-Load function makes
it possible to remotely switch an FS compressor,
e.g. from a control room, off and on-load. Condi-
tion: "Enable Remote Load" is activated.
See chapter "Configuration / Remote load and off-
load (FS)".
