Maintenance and repair

POTENTIALLY fatal danger due to electrical voltage
There is a risk of fatal electric shocks occurring
when performing work on the open switchgear.
During all work, the switchgear must be discon-
nected from the electricity network and secured
against reactivation without permission. All
electrical work must be carried out by a qualified
electrician.
After completing maintenance or repair work, the switchgear must
be connected according to the "Installation" section and activated
as under "Commissioning".
Maintenance or repair work and/or constructional
changes that are not listed in this operating and
maintenance manual may only be carried out by the
manufacturer or by authorised service centres.
9.1.

Maintenance intervals

To ensure reliable operation, various maintenance tasks must be
carried out regularly.
NOTE
When used in sewage lifting units inside buildings or
on land plots, the maintenance intervals and work
shown in DIN EN 12056-4 must be adhered to.
Before initial commissioning or after a longer period of
storage:
• Clean the switchgear
Yearly
• Visual inspection of individual components
9.2.

Maintenance tasks

Prior to maintenance work, the switchgear must be switched off
as described under "Temporary shutdown". Maintenance work
may only be carried out by qualified persons.
9.2.1. Clean the switchgear
Use a damp cotton cloth to clean the switchgear.
Do not use any aggressive or scouring cleaners or
fluids!
9.2.2. Visual inspection of individual components
Have the individual components checked for wear by a qualified
electrician or Salmson Customer Service (e.g. melting of protective
contacts, deformation of plastic parts).
If more serious wear is ascertained, have the affected components
replaced by a specialist electrician or Salmson Customer Service.
9.3.

Repairs

Prior to repair work, the switchgear must be switched off as
described under "Final shutdown" and all power supply cables dis-
mantled. Repair work must be carried out by an authorised service
centre or Salmson Customer Service.

Troubleshooting and possible solutions

DANGER due to electrical voltage
Improper procedures during electrical work may
result in fatal injuries caused by electrical voltage!
Such work may only be carried out by a qualified
electrician.
Potential faults are indicated visually and audibly. According to the
fault shown, the connected pump or signal transmitter must be
checked for correct operation and replaced if necessary.
Only perform this work if suitably qualified personnel are available.
Electrical work must be carried out by qualified electricians for
instance.
We recommend always having this work carried out by Salmson
Customer Service.
Unsanctioned modifications to the switchgear are made at the
operator's own risk and release the manufacturer from any war-
ranty obligations.

10.1. Acknowledging faults

After a fault occurs, a visual and audible warning is
output.
By briefly pressing the Buzzer OFF/reset button, the au-
dible alarm is deactivated and collective fault signal relay
(SSM) acknowledged.
When held down for longer (min. 1 sec), the fault is ac-
knowledged and the control is reenabled.
A fault can only acknowledged once it has been elim-
inated!
