7.4.2. if the direction of rotation is not correct
After activation, an audible signal sounds and all
LEDs flash in turn anti-clockwise:
The switchgear is incorrectly connected and the
connected pump is not operating correctly.
2 phases/conductors of the power supply on
mains side to the switchgear need to be swapped.
Pump running incorrectly:
Connection of the switchgear is correct. Con-
nection of the pump is incorrect. 2 phases of the
mains supply to the pump supply line need to be
swapped.

7.5. Activating automatic mode on the unit

Before automatic mode is switched on, check the
settings for the switching level and follow-up
time.
If all settings have been checked, you can switch
the unit on.
1. Press the "auto" button on the control panel.
2. The "auto" LED lights up and the unit now runs
in automatic mode. As soon as the float switch-
es provide a corresponding signal, the pump is
activated
• "Pump ON" level: If the activation level is reached,
the pump switches on and the "Pump operation"
LED lights up permanently.
• "Pump OFF" level: If the off level is reached, the
follow-up time set is active. During the follow-up
time, the "Pump operation" LED flashes. Once the
follow-up time has expired, the pump switches
off and the "Pump operation" LED goes out.
NOTE
High-water protection is active in automatic
mode. When the activation level for high-water
protection is reached, the following occurs:
• forced switch-on of the pump
• a visual warning, the "High water" LED, lights up
permanently
• an audible warning is emitted via a constant
signal.
• the collective fault signal contact (SSM) is
activated.

7.6. Conduct during operation

When operating the switchgear, always follow the
locally applicable laws and regulations for work
safety, accident prevention and handling electri-
cal products.
To help to ensure safe working practice, the
responsibilities of employees should be clearly set
out by the operator. All personnel are responsible
for ensuring that regulations are observed.
Check the settings at regular intervals as to
whether they meet the current requirements. The
settings may need to be adjusted.

occur:
• forced switch-on of the pump
• visual and audible warning
• activation of the collective fault signal contact
(SSM).

8.2. temporary shutdown

For temporary deactivation, the control is
switched off and switchgear is switched off via
the main switch.
The switchgear and the unit are now ready for
operation at any time. The defined settings are
stored retentively in the switchgear and are not
discarded.
Make sure that the ambient conditions are ob-
served accordingly:
• Ambient/operating temperature -30 ... +60 °C
• Air humidity: 40...50 %
Prevent formation of condensate!
BEWArE of moisture!
ingress of moisture will result in damage to
the switchgear. During standstill time, pay
attention to the permissible air humidity and
ensure the switchgear is stored so it is safe
from overflowing.
