8.5.2 Configuring the digital input
Option
Description
0 - 4 = Deactivated
Connection not operational
5 = Rotation speed setting mode
Control corresponds to parameter [P:026]
Tbl. 13:
Configure parameter [P:063]
8.5.3 Selecting the interfaces
The parameter [P:060] indicates the current selected interface with operating priority. The electronic
drive unit only accepts control commands via the interface with operating priority. If the actual setting is
not locked by the parameter [P061] = 1, if another interface issues a control command, operating priori-
ty is automatically transferred to the other interface.
Option
Description
1 = remote
Operation via connection “remote”
2 = RS-485
Operation via connection “RS-485”

8.6 Selecting operating mode
After applying the operating voltage, the electronic drive unit carries out a self-test to check the supply
voltage.
The following operating modes are possible:
● Operating without control unit
● Operation via an external control unit
● Operation via RS-485 and peripheral device or PC
● Operation with automatic start
Operating vacuum pump without controller
1. Establish the current supply.
2. Operate the vacuum pump with the on/off and standby buttons.
Operating vacuum pump with external controller
1. Connect a remote control via the "remote" 15-pin D-Sub socket.
2. Control the vacuum pump by means of the “PLC level”.
Operating vacuum pump with peripheral device
1. Observe the operating instructions of the peripheral device.
2. Connect the respective peripheral device to the “remote” 15-pin D-Sub socket.
3. Make the desired settings via the RS-485 using the peripheral device.
Operating vacuum pump with auto start function
► Parameter
[P:010] = 1
: Hold the
button pressed for longer than 5 s.
– This switches off the auto start function:
[P:034] = 0
. The vacuum pump itself remains activat-
ed. In the event of a return to the mains following a power failure, the vacuum pump remains
deactivated.
► Parameter
[P:010] = 0
: Hold the
button pressed for longer than 5 s.
– This switches on the auto start function:
[P:034] = 1
. The vacuum pump itself remains deacti-
vated. In the event of a return to the mains, the vacuum pump restores the operating status
which was established prior to the power failure.
To confirm the command, the yellow LED flashes for 1 second after releasing the button.
8.7 Selecting speed mode
The vacuum pump has different speed modes.
Operation
