•
VENT VALVE MODE: makes it possible to select
driving of the vent valve
- AUTO TIME: the valve is controlled by the
controller
-
MANUAL: the valve is controlled by the serial
port.
-
AUTO PUMP SPEED: the valve is controlled
by the controller its king into account the
pump's deceleration.
•
VENT VALVE DELAY: Sets the delay, expressed
in seconds, between stopping of the pump and
opening of the vent valve.
•
VENT VALVE OPEN TIME: sets the time,
expressed in seconds, of opening of the vent
valve. Enter 0 if the valve is to be kept open
indefinitely (until the next start).
•
LOAD GAS TYPE: selects the type of gas used in
the process. Therefore, the controller limits the
power supplied to the pump according to the
setting of this parameter.
•
WATER COOLING: indicates whether the pump is
cooled with water or not. The controller limits the
power supplied to the pump according to this
setting.
•
ACTIVE STOP: enables (YES) or disables (NO)
active braking.
•
STOP SPEED READING: enables (YES) or
disables (NO) the pump rotational frequency
reading function also during the slowing phase that
follows a stop command

START MODE: Permits selection of one of the
three types of functioning of the START/STOP and
INTERLOCK inputs:
- START/INTERLOCK: The pump is started if
the START/STOP input is activated and is
stopped if the START/STOP input is de-
activated.
constantly
parameter = continuous) or may be active only
at the time of starting (INTERLOCK TYPE
parameter = impulsive)
-
START/STOP LEVEL The START/STOP input
acts as only START command (active on the
level) The INTERLOCK input acts as STOP
command (active on the level)
In the case of concurrent activation of the two
inputs, the STOP command takes priority
- START/STOP EDGE The START/STOP input
acts as START command (active on the edge)
The INTERLOCK
command (active on the edge).
•
INTERLOCK TYPE: This parameter is displayed
only when the previous parameter (START MODE)
is equal to START/INTERLOCK and permits
selection of one of the following two operating
modes of the INTERLOCK input:
- CONTINUOUS: the INTERLOCK input must
be active continuously so that the pump can
be driven by the controller. If, with the
controller in start, the input INTERLOCK is de-
activated, the controller switches to WAITING
INTERLOCK status and interrupts driving of
the pump
- IMPULSIVE: it is sufficient for the input to be
active when the START command is sent to
the pump. Subsequently, the input can also be
de-activated. If the interlock is not active when
the pump is started, the controller switches too
WAITING INTERLOCK status.
•
ANALOG OUT TYPE: permits selection of the type
of signal to be sent to the programmable analogue
output. One of the following signals can be
selected:
- FREQUENCY: the drive frequency of the
pump is shown
- POWER: the power supplied to the pump is
shown
-
TEMPERATURE: the temperature of the pump
is shown
-
PRESSURE: the pressure read by the gauge
is shown.
•
START OUT MODE: Selects the operating mode
of the START output. Possible options:
-
RUNNING: the output is active when the pump
is driven
-
STARTING: the output is active only during
acceleration ramp-up.
•
SPEED OUT MODE (KRPM/Hz): permits selection
of the unit of measurement of the speed of rotation
shown on the display of the controller.
This setting acts only on the measurement shown
on the display. Possible options:
-
KRPM
-
Hz
