Instruction Manual MINK MV 0500-0600 B_EN_en 25 | 40
7.1.4.1 Parameter settings for exact pressure control
PID Control Settings
P3.13.1.1 PID Gain
If the value of the parameter is set to 100% a change of 10% in the error value causes the controller
output to change by 10%.
Preset value: 400%
P3.13.1.2 PID Integration Time
If this parameter is set to 1.00 second a change of 10% in the error value causes the controller out-
put to change by 10%/s.
Preset value: 0,5 s.
Nominal Values
P3.13.2.1 Keypad SP 1
Setting the nominal value in mbar.
Preset value: 400 mbar
Sleep Settings
Sleep will put the machine to sleep-mode when the pressure level is steady.
P3.13.5.1 SP 1 Sleep Frequency
This function will put the drive into sleep mode if the set point is reached and the output frequency
stays below the sleep limit for a longer time than set in the sleep delay
Preset value: 20,2 Hz
● do not set the value below 20,2 Hz, otherwise sleep-mode will be disabled.
P3.13.5.2 SP 1 Sleep Time Delay
Time of working at minimum frequency, before entering sleep-mode condition.
Preset value: 5s
P3.13.5.3 SP 1 Sleep Wake-Up Limit
Defines the PID feedback error limit for the wake-up function. The drive exits from sleep-mode if the
Error exceeds this value.
Preset value: 10,0 mbar
7.2 Conveying Condensable Vapors
Use the machine in Aqua version for conveying water vapor or other condensable vapors. The ma-
chine in Aqua version is able to convey up to 100% saturated water vapor.
The conveyance of other vapors than water vapor shall be agreed upon with Busch.
● Make sure that any condensate from the suction side will not enter the non-operating machine.
● Before process:
● Warm up the machine by running the machine for 30 minutes.
● After process:
● During process condensate may occur in the machine. To remove the condensate from the
machine, convey dry air at 400 mbar with the machine’s maximum speed for 30 minutes, after
the process and at least once a day.
