6.1
TO DO
TO CRITICAL PARTS
The following instructions
CRITICAL to the owner's safety. Be
to follow
the instructions. Contact the
manufacturer or
if you have any question.
1. If the oven is operative prior to
a Microwave Leakage Test (a. k. a. Microwave Emission Check)
should be
prior to
the oven Refer to Section 7.3, Microwave Leakage Test. For the
detailed check procedures.
2. In the event that any microwave oven found to have microwave emission level in excess of 4 mW/cm2. The
following procedures should be followed:
(1). .Inform the distributor;
or manufacturer the finding. Record it in the logbook as
(2).
the unit at no cost to the owner.
(3).
the oven and
the cause of the excessive leakage.
(4).
the oven in your facility and instruct the owner not to use the
the oven has.
3. In the event that the oven operates with the door open. The following procedures should be followed:
the user not to operate the oven.
(2).
the oven in your facility until it is investigated and repaired.
(3). Contact the manufacturer and CDRH (FDA) immediately.
6.2 INTERLOCK
AND
1. If you suspect defective
or monitor interlock
use your ommeter (digital or
analog type) to check the electrical continuity.
2.
the power cord is pulled out and the high-voltage capacitor is discharged before the electrical
continuity check.
3. Set the ohmmeter to
rangę and connect both
(alligator elips) to the switch terminals.
4. Open the door and notice the meter reading the primary or secondary interlock switch should show an
resistancc when the door is open. Replace it when it is defective. The monitor interlock should show
a "zero or near zero" resistance when the door is open. When the door is closed, the readings will be
opposite.
5. If the oven has been rendered inoperative due to the failure of the monitored safety (primary and
secondary ) interlock(s). You should replace all of the monitored safety interlock switched and the monitor
switch.
6. Refer to Chapter 4, Sections l and X for
to remove and assemble the interlock and monitor switches.
7. Always refer to Section 0.4 for adequate wiring diagram. Monitor interlock
always be installed. Repeat
Step 6.2.4 to check electrical continuity.
8.
required checks and tests as described in Chapter 7 before releasing the oven to the owner.
