4.5.3
Extended Operation (“Analog Control Mode”)
▪ In order to be able to control the pump with external signals (PLC) the mode “Analog Control
Mode” has to be set with the display buttons. The “UP” and “Down” buttons have to be pressed
simultaneously during 5 seconds. The display should feedback the change by blinking between
the stored speed value and “An”. The chosen mode is then stored in the EEPROM of the
controller.
▪ The system and levitation can be enabled/disabled with the digital input on the “USER
INTERFACE” connector (see
Table 13). When disabling the running system, the speed is
automatically reduced to 0 rpm and the impeller is smoothly touched down without grinding the
wall.
▪
The speed can be set with an analog signa
l on the “USER INTERFACE” connector according to
Table 13 . It is strongly recommended to use galvanic separated signal values
▪
For monitoring purposes a
digital output on the “USER INTERFACE” connector (see
Table 13 )
indicates an error. In case of an error the codes described in Table 15 are displayed (blinking
between “An” and the according code number)

Controller
Supply voltage out of range (Power input)
(Ext. range: < 90 or > 378 V DC corresponds to < 64 VAC or > 267 VAC Input)
If the voltage is out of extended range the system starts to reduce the speed and an error is
generated. When reaching 0 rpm and the voltage is still out of extended range the system is
disabled.

Pump
Dry Running Detection
Pump keeps running on reduced speed (5000 rpm).
The system accelerates to the original speed value when the pump is refilled with liquid.
Note that the speed is only reduced during dry running if the pump speed was ≥ 6000 rpm.

Note 1: In case of an error the system can only be restarted with a reset or a power supply restart.
Note 2: Description is for standard firmware.
Note 3: For other configurations of error codes refer to alternate controller or firmware documentation.
