SHUTDOWN/DISPOSAL

7.4.2. If the direction of rotation is incorrect
The fault code "E06" (rotating field error) will
appear on the display.
The switchgear is incorrectly connected and all
connected pumps are operating incorrectly.
2 phases/conductors of the power supply on
mains side to the switchgear need to be swapped
over.
Pump is operating incorrectly (without error
code E06):
Connection of the switchgear is correct. Connec-
tion of the pump is incorrect.
• In case of motors with direct starting, 2 phases of
the pump supply line must be swapped over.
• With star delta activation motors, the connec-
tions of two windings need to swapped over, e.g.
U1 with V1 and U2 with V2.

7.5. Automatic mode on the unit

NOTE
Observe the installation and operating in-
structions for products provided on-site (float
switches, level sensors, connected consumers)
as well as the system documentation!
7.5.1. Activating automatic mode on the unit
If all settings have been checked, you can switch
the unit on using menu item 3.1.0.0.
1. Select menu item 3.1.0.0.
2. Select "ON"
3. The unit now runs in automatic mode. As soon
as the signal transmitters supply a corresponding
signal, the relevant pumps are activated
7.5.2. 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 ensure safe working practice, the respon-
sibilities of employees should be clearly specified
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.

7.6. Emergency operation

POTENTIALLY fatal danger due to electrical
voltage!
To operate the separate main switches
for each pump by hand, the cover must be
opened. There is a risk of fatal injury due to
live parts! This work may only be carried out
by a qualified electrician.
In case of a control failing, the individual pumps
can be switched on manually.
Installation and operating instructions Wilo-Control SC-L
In such cases, each connected pump can be acti-
vated separately via the relevant HAND-0-AUTO
switch on the switchgear.
• Switch-on: Set the switch to "HAND (H)".
• Switch off: Set the switch to "0 (OFF)".
• For automatic mode, the switches need to be
reset to "AUTO (A)".
If the connected pump is switched on via the
separate HAND-0-AUTO switch in the switch-
gear, this will run constantly. No regulation will
take place via the control. Make sure that the
permissible usage conditions for the pump are
observed accordingly!
8. Shutdown/disposal
• All work must be carried out with the greatest
care.
• Proper protective clothing is to be worn.
• When working in enclosed spaces, a second per-
son must be present for safety reasons.

8.1. Deactivating automatic mode on the unit

1. Select menu item 3.1.0.0.
2. Select "OFF"
3. The system now runs in stand-by mode.

8.2. Temporary decommissioning

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: 0 ... 40 °C
• 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 humidity and
ensure the switchgear is stored so it is over-
flow-proof.
1. Switch off the switchgear using the main switch
("OFF" position).

8.3. Final shutdown

POTENTIALLY fatal danger due to electrical
voltage!
Incorrect procedures can cause fatal electric
shocks. This work may only be carried out by
a qualified electrician approved by the local
power supplier, in accordance with locally
applicable regulations.
1. Switch off the switchgear using the main switch
("OFF" position).
