General Information
If the 220 pressure transducer fails to operate properly upon receipt, check for shipping damage,
and check the cables for proper continuity. Any damage should be reported to the carrier and
MKS Instruments immediately. If it is necessary to return the unit to MKS, obtain an RMA
(Return Material Authorization) number from a MKS Service Center before shipping. Please
refer to the inside back cover of this manual for a list of MKS Calibration and Service Centers.
All returns to MKS Instruments must be free of harmful,
corrosive, radioactive, or toxic materials.
There are no user-repairable parts in the 220 transducer.
Periodically check for wear on the cables and inspect the enclosure for visible signs of damage.
How To Clean the Unit
To clean the unit, wipe down the enclosure with a damp cloth.
How To Change the Fuse(s)
1. Select the appropriate fuses.
Refer to Table 6, page 26, for the fuse information.
2. Disconnect the power cord from the controller.
Disconnect the power cord before proceeding to avoid an
electrical shock.
3. Insert a small, flat head screw driver under one side of the black fuse holder, then the
other, to disengage the fuse holder.
Refer to Figure 6, page 26, for the location of the fuse holder clip. The fuse holder will
slide partially out of the instrument.
4. Carefully slide the fuse holder out and remove the fuse.
5. Insert the new fuse into the fuse holder.
Be certain that the new fuse is the appropriate type for the line voltage selection.
