English
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
Menu 5.5.2.0 / SSM
The required logic of the collective fault signal can be set:
• "Fall": negative logic (falling edge)
• "Rise": positive logic (rising edge)
Menu 5.6.0.0 / Pump cycling
To prevent irregular standstill times for the individual pumps,
either general or periodical pump cycling can take place.
With general pump cycling (menu 5.6.1.0), the base-load pump is
always replaced after all pumps have been switched off.
With periodical pump cycling (menu 5.6.2.0), the base-load pump
is always changed after a fixed set time (menu 5.6.3.0).
If running time differences of more than 24 h occur among the
available pumps, the pump with the least operating hours is used
as the base-load pump until the difference has been compensat-
ed.
Menu 5.7.0.0 / pump-kick
To prevent longer standstill times for the connected pumps, a pe-
riodical test run can be performed (pump kick function).
The time interval after a pump kick should be set in menu 5.7.2.0.
The running time for the pump kick is set in menu 5.7.3.0.
6.5. Forced activation of the pumps in case of dry running or
high water
Forced switch-on or deactivation of pumps on reaching dry run
and high water level only takes place if level measurement of both
values is via a float switch.
6.6.

Standby pump

It is possible to use one or more pump(s) as a standby pump. This
pump is not activated in normal operation. It is only activated if
a pump malfunctions due to a fault.
The standby pump is subject to standstill monitoring however and
is activated during pump cycling and pump kick.
This function can be activated or deactivated by
Salmson customer service.
6.7. Operation in case of a fault to the level sensor
If no measured value is detected via the level sensor (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 Salmson customer service.

Commissioning

POTENTIALLY fatal danger due to electrical voltage
Incorrect electrical connections can cause fatal
electric shocks. Electrical connections may only be
inspected by a qualified electrician approved by the
local energy supply company, in accordance with
locally applicable regulations.
The "Commissioning" section contains all the important instruc-
tions 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 per-
sonnel 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 understood 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 "In-
stallation" 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 specified
operating conditions.
7.1.

Level control

The signal transmitters are installed according to the unit specifi-
cations and the desired switching points set.
When using a level sensor, the switching points were set via the
menu.
7.2.

Operation in potentially explosive areas

The switchgear may not be installed or used in potentially explo-
sive areas.
Monitoring devices and signal transmitters used within potentially
explosive areas may only be connected to the Ex variant of the
switchgear (SC-L...-Ex).
RISK of fatal injury due to explosive atmosphere!
The switchgear is not Ex-rated. Operation in
potentially explosive areas will lead to explosions!
The switchgear must always be installed outside
potentially explosive areas!
7.3.

Activating the switchgear

NOTE
Following a power supply interruption, the switch-
gear will automatically start up in the last operating
mode set!
1. Turn main switch to ON position.
2. All LEDs light up for 2 s and the current operating data and
the standby icon appear on the LC display.
