Maintenance
Section 4.0
This section contains information useful in the
maintenance and repair of the System 2450.
WARNING: High voltages are present at
the connections and within the System 2450.
Maintenance personnel should take precau-
tions to protect themselves. Read the safety
summary in Section 1.1.4 of the System 2450
Operators Manual before working on the
ESU.
4.1 General Maintenance Information
Although the System 2450 has been designed
and manufactured to high industry standards, it is
recommended that periodic inspection and perfor-
mance testing be performed to ensure continual
safe and effective operation.
Ease of maintenance was a primary consideration
in the design of the System 2450. Maintenance
features of this unit include microprocessor aided
troubleshooting aids and push button calibration,
built in fault detection, circuit protection, and easy
access to circuitry while the unit is operational.
These features, coupled with the warranty, local
support, loaner equipment, factory support, toll
free phone service to the factory and available fac-
tory training ensure a minimal maintenance effort
with extensive support available.
4.2 Maintenance Personnel
Only Hospital Qualified Biomedical Technicians
or ConMed factory technicians should perform
service on the System 2450. Refer all servicing to
a Hospital Qualified Biomedical Technician.
If necessary, your CONMED sales representative
will be happy to assist you in getting your equip-
ment serviced.
4.3 Cleaning
The interior of the unit may be vacuumed or
blown out as required. The exterior of the unit
may be cleaned by wiping it with a cloth that
has been dampened (not dripping) with a mild
detergent such as Windex® or Formula 409®.
(Windex® is a registered trademark of the S.C.
Johnson Company. Formula 409® is a registered
trademark of the Clorox Company.)
4.4 Periodic Inspection
The System 2450 should be visually inspected at
least every six months. This inspection should
include checks for the following:
1) Damage to the power cord and plug.
2) Proper mating and absence of damage to the
accessory connectors.
3) Any obvious external or internal damage to
the unit.
4) Any accumulation of lint or debris within the
unit or heatsink.
5) Control Panel cuts, punctures, or dents.
4.5 Periodic Performance Testing
The System 2450 should be tested for correct
performance at least once every year. Every unit
is supplied with a serialized Production Test Data
Sheet that tabulates the results of the factory tests
that were performed on the unit. This data is
supplied so that it may be used as a reference for
subsequent tests.
Recommended periodic performance tests are
listed in the following sections.
4.5.1 Chassis Ground Integrity
Connect a standard ohmmeter between the
earth ground prong on the power plug and the
Equipotential Ground Connection. Compensate
for lead resistance. Confirm less than 0.2 ohms
resistance is measured.
4.5.2 Displays, Alarms and Commands
Perform the Preliminary Functional Test procedure
described in section 2.3.1 of the System 2450
Operators Manual to verify proper operation of
displays, alarms and commands.
