System vacuum evaluation:
Once the system vacuum reaches the value for H2, the following responses are triggered:
• The process data bit for H2 is set.
• The H2 LED on the ejector's display illuminates.
Once the system vacuum reaches the value for H1, the following responses are triggered:
• Depending on whether the air saving function is selected, vacuum generation is interrupted.
• The process data bit for H1 is set.
6.4.2 Control Functions (0x006D)
The ejector allows you to conserve compressed air or prevent a too powerful vacuum from being gener-
ated. Vacuum generation is interrupted once the configured switching point H1 is reached. If leakage
causes the vacuum to fall below the hysteresis switching point (H1-h1), vacuum generation resumes.

Description Control mode for ejectors
Index Index 0 to 15 corresponds to ejector #1 to #16
Data type uint8
Length 16 bytes
Access Read/write
Value range 0x00 = control is not active, H1 in hysteresis mode
0x01 = control is not active, H1 in comparator mode
0x02 = control is active
0x03 = control is active with monitoring of leakage
0x04 = control is active, continuous sucking disabled
0x05 = control is active with monitoring of leakage, continuous sucking dis-
abled
Default value 0x02 = control is active
