Each ejector offers three blow-off modes for selection:
Externally Controlled Blow-Off
The ejector switches to blow-off mode for as long as the blow-off signal is present.
The blow-off signal is given priority over the suction signal.
Internally Time-Controlled Blow-Off
After the suction signal is switched off, the ejector switches to blow-off mode automatically for the set
time. With this function, the blow-off signal does not have to be additionally controlled.
The blow-off signal is given priority over the suction signal. This applies even when the set blow-off time
is very long.
Externally Time-Controlled Blow-Off
The blow-off starts with the blow-off signal and is performed for the set time period. Applying the blow-
off signal for a longer time does not lead to a longer blow-off period.
The blow-off signal is given priority over the suction signal. This applies even when the set blow-off time
is very long.
Setting the Blow-Off time [P-0: 0x006A]
If the blow-off function of the ejector is set to internally time-controlled or externally time-controlled
“Blow-off”, then the blow-off time may be specified.
The time can range from 0.10 to 9.99 seconds.
6.4.4 Set Permitted Evacuation Time t1 (0x006B)
The permitted evacuation time t1 is specified in milliseconds. The measurement starts when the switching
threshold H2 is reached and ends when the switching threshold H1 is fallen below.
