10.7 Venting settings
(only with RS 204.1)
There are three venting modes:
Manual venting
Venting after switching on the pump
Cyclical venting
Manual venting
This mode is always activated, which means that venting using
the AUTO/MANU key (see Chapter 10.7.1) is possible at any
time, no matter whether additional venting modes are activated
and regardless of which operation mode the pump is in.
Venting
when switching on the pump
In this mode, venting is performed once, namely directly after
the pump has been switched on (operation of the
STOP/START key). Venting time is set upon activation of this
mode (see Chapter 10.7.2).
Moreover, this mode allows the external control of the vent
valve via the external stop input. After having removed the ex-
ternal stop signal, the pump will vent for the preset time.
For deactivating the mode, please see the description in Chap-
ter 10.7.4.
Cyclical venting
In this mode, venting is cyclically repeated after a predeter-
mined pause time. Venting time and pause time duration are
set upon activation of this mode (see Chapter 10.7.3).
For deactivating the mode, please see the description in Chap-
ter 10.7.4.
NOTE !
Venting is always performed with 100% stroke frequency
–
regardless of the preset stroke frequency!
CAUTION !
After pump and suction line have been vented, there might
be the possibility (depending on the backpressure) that
small fluid quantities are already conveyed into the pres-
sure line although the vent valve is still open.
The venting period must therefore be coordinated with the
possible gas volume on the suction side of the pump.
NOTE !
In all operating modes of the venting valve the maximum
venting time is 5 min and the minimum interval time is 15
min!
10.7.1 Manual venting
The manual operation of the vent valve is done using the
AUTO/MANU key. Venting does not start until the key is
pressed for 3 sec. Venting remains active as long as the key is
pressed. After releasing the key, the venting will be stopped.
