Fuses

CAUTION: Unplug the controller before replacing the fuse(s).
Blown fuses should only be replaced by those indicated on the power supply board near the location of the fuses at
the AC inlet. Use only 1.6 A, 250 VAC, 5x20mm Slo Blo fuses. The use of fuses that have the Semko and/or VDE marking
is preferred. If a fuse blows a second time, it should be presumed that the controller is defective and requires further
service. Please contact your service center. Fuses are not accessible from the outside of the controller. Refer to the
Disassembly/Reassembly procedures later in the manual. The fuses are located on the power supply board as part of
the power inlet module under the fuse cover.
Electrical Safety CAUTION: Be sure the controller is disconnected from the AC power source before any disassembly.
A potential SHOCK HAZARD exists when the front cover is removed even with the unit turned off.
Note: The power supply cord/plug serves as the electrical supply mains disconnect device.
To facilitate electrical safety testing, the controller has an equipotential lug, located on the back of the device opposite
the power cord. There are no other grounded exposed metal parts. Power cord resistance should not exceed 0.2
ohm. If ground resistance exceeds this value or the insulation integrity of the unit has been compromised through
mechanical damage, the controller should be returned to a service center for testing and repair.

Suggested Preventative Maintenance Schedule

The expected service life of the Kendall SCD™ 700 series controller is 5 years. However, the life of the controller can be
extended indefinitely by replacing components if they fail. Refer to the spare parts listing within this Operation and
Service Manual.

Error History

The Kendall SCD™ 700 series compression system stores the ten most recent error codes for use in troubleshooting
devices returned from use. There is a test access mode, discussed later in this manual that describes exactly how to use
the feature.

Cleaning

CONTROLLER CLEANING

The controller enclosure can be cleaned with a soft cloth
dampened with water or a mild detergent. To sanitize the
device, apply cleaning agents with a cloth or wipe. Avoid
excessive spraying, especially in the areas of the connection
ports on the back of the device. If any liquid enters the ports,
then internal component damage will likely result. The
table at right provides optional cleaners and their chemical
components.
The Kendall SCD™ 700 series compression system cannot be
effectively sterilized by liquid immersion, autoclaving, or ETO
sterilization, as irreparable damage to the System will occur.
