Repair and maintenance
1.4
Repairs are subject to checking and can be carried out only at Sartorius. In case of defect or functional trouble,
please contact your local Sartorius organization for repair. When returning the instrument for repair, an exact
and complete fault description must be supplied. Maintenance work may be carried out only by a trained
technician aware of the involved hazards, whereby the relevant precautions must be taken.
1.4.1 Failure and excessive stress
If the instrument is suspected of being unsafe, shut it down and protect it against accidental operation. This is
the case when the unit
• is physically damaged,
• does not function any more,
• is stressed beyond the tolerable limits (e.g. during storage, transport).
1.4.2 For special attention
Make sure that the construction of the instrument is not altered to the detriment of safety. In particular,
leakage paths, air gaps (of live parts) and insulating layers must not be reduced. The manufacturer cannot be held
responsible for personnel injury or damage caused by an instrument repaired incorrectly by user or installer.
1.4.3 Fuses
! WARNING !
Two mains fuses of 315 mA slow blowing are located in the Euro-power connector on the rear side of the
instrument.
The secondary transformer winding is protected by a Multifuse 1,85 A and the load cell supply is proteted by a
Multifuse 0.5 A. If a Multifuse switches off : Disconnect the device from power, after a cooling down period of
about 3 min. it can be used again.
The transformer primary winding is protected by means of a thermal fuse. After overheating, the thermal fuse is
molten. The PR 5710 has to be sent to our service for repair.
1.4.4 Soldering work
The PR 5710 Basic unit does not require any soldering work.
Sartorius
Only a qualified person may replace fuses.
