COMMISSIONING
Menu 5.4.7.0 / Behaviour in case of mains con-
nection errors
This function can only be used with a 3~-mains
connection. With a single-phase mains connec-
tion, this function needs to be deactivated. The
following options are available:
• "OFF": Function deactivated
• "Message": Note on LC display
• "Stop Pumps" Note on LC display and deactiva-
tion of all pumps
Menu 5.4.8.0 / Behaviour on activation of
thermal motor winding monitoring and leakage
detection
The temperature sensors and the moisture probe
must be connected to the corresponding termi-
nals in accordance with the wiring diagram!
The following options are available:
• "Auto Reset": When the winding has cooled down
and/or the leakage has been eliminated, the pump
is automatically restarted
• "Manu Reset": When the pump has cooled down
and/or the leakage has been eliminated, the error
needs to be acknowledged manually so that the
pump restarts.
In the Ex-version of the switchgear (SC-L...-Ex),
a manual reactivation lock is additionally installed
for temperature monitoring, which must be man-
ually reset.
POTENTIALLY fatal danger due to electrical
voltage!
To reset the relay 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.
Menu 5.4.9.0 / Behaviour when "External OFF"
contact is open
Automatic mode on the switchgear can be acti-
vated and deactivated via the "External OFF" con-
tact using a remote switch (e.g. a float switch).
This enables additional dry-running protection to
be realised for example. This function overrides all
other switching points and all pumps are switched
off. If this function is used, you can stipulate how
signalling should take place in case of an open
contact here:
• "Ext.Off": Automatic mode is deactivated and the
symbol appears on the LC display.
• "Alarm": Automatic mode is deactivated and the
symbol appears on the LC display. An alarm signal
is also emitted.
Menu 5.5.1.0 / SBM
The required function of the collective run signal
can be set:
• "Ready": Switchgear ready for operation
• "Run": At least one pump is running
Installation and operating instructions Wilo-Control SC-L...-FTS
Menu 5.5.2.0 / SSM
The required logic of the collective fault signal
can be set:
• "Fall": negative logic (falling edge)
• "Raise": positive logic (rising edge)
6.6. Forced switching of the pumps in case of dry
run
Forced activation of the active pump takes place
on reaching the dry running level.
6.7. Operation in case of a fault to the level sensor
If no measured value is detected via the level sen-
sor (e.g. due to a wire break or a defective sensor)
all pumps are deactivated, the fault LED lights up
and the collective fault signal contact is activated.
6.8. Factory settings
The switchgear is pre-set in the factory using
standard settings.
If you wish to reset the switchgear to these
factory settings, please contact Wilo customer
service.
7. Commissioning
POTENTIALLY fatal danger due to electrical
voltage!
Incorrect electrical connections can cause fa-
tal electric shocks! Electrical connections may
only be inspected by a qualified electrician
approved by the local energy supply company,
in accordance with locally applicable regula-
tions.
The "Commissioning" section contains all the
important instructions for operating personnel
on commissioning and operating the switchgear
safely.
Always keep this manual either by the switchgear
or in a place specially reserved for it, where it is
accessible for all operating personnel at all times.
All persons working on or with the switchgear
must have been provided with this operating and
maintenance manual and have read and under-
stood it.
In order to prevent damage or serious injury when
commissioning the switchgear, the following
points must always be observed:
• The switchgear must be installed as described in
the "Installation" section and in accordance with
the applicable national regulations.
• The switchgear must be properly fused and
grounded.
• All unit safety devices and emergency cut-outs
must be connected and inspected to ensure that
they are working properly.
• The switchgear is suitable for use under the spec-
ified operating conditions.
