REJECT COUNTER (MPC ONLY)
The MPC stores a running total of the number
of times the Direct Reject output has cycled.
This normally provides a very close approxi-
mation of the total number of detections while
preventing multiple counts of the same piece
of tramp metal.
Maximum Count: 9999.
REJECT REPORTS (MPC ONLY)
The MPC stores pertinent data on the most
recent 100 rejects. Report Number, Product
Number, Time, Date, and Peak Signal Level
can be reviewed on the LCD display. The re-
ports can be downloaded to a remote printer.
In this case, Travel Time, Timed Reject Time,
Sensitivity, Gain, and Product Description are
also included in the report. The reports can
be downloaded to a remote computer. The
computer report contains all information men-
tioned above plus Phase, Filter Frequency,
Detect Mode, Fault Status, Date & Time that
any one of the variables was last changed,
Direct Reject Time, Window Time, and status
of Tach Input, Direct Reject Auto Reset, Timed
Reject Auto Reset, Space Between Products,
Index Device Used?, and Reject Confirmation.
ENVIRONMENT
Ambient Temperature 0
°
C (32
°
F) to 50
°
C
(122
°
F) during operation.
Storage Temperature -10
°
C (14
°
F) to 80
°
C
(176
°
F).
Relative Humidity 0 to 95%.
NOTE: When stored at or below 0
°
C for
longer than six hours and then moved to a
warmer location, the temperature of the unit
should be allowed to stabilize long enough to
allow drying of moisture which may have ac-
cumulated on the electronic components (over-
night is recommended). DO NOT APPLY
POWER UNTIL ELECTRONIC CIRCUITRY IS
COMPLETELY DRY.
ENCLOSURE RATING
NEMA-4X/IP66.
PRODUCT VELOCITY
The metal detector can be adjusted to scan
products traveling from approximately 2 ft./min.
to 7800 ft./min. (.6 m/min. to 2400 m/min.) de-
pending on the size and type of sensing head.
The unit is set up at the factory for optimal
performance for the customer’s application and
requires no further adjustment.
FREQUENCY
The metal detector operating frequency de-
pends on the aperture size and the character-
istics of the product to be inspected. It is ad-
justable but this is normally not required un-
less another metal detector in the area causes
interference. In this case consult the factory
for adjustment details.
BATTERY LIFE (MPC ONLY)
Minimum 1.4 years; maximum 5.0 years.
COMMUNICATION (MPC ONLY)
Printer-RS 232 (see Appendix A).
Computer-RS 232/485 (see E-Z Tec MPC
Communications Manual MM-237).
PRODUCT DESCRIPTION (MPC ONLY)
32 alphanumeric characters of description can
be stored for each of 32 separate products.
DIAGNOSTICS (MPC ONLY)
Automatic self-checking for proper operation
of the metal detector electronics at user defin-
able intervals
Detector can show Fault condition when user-
scheduled calibration procedure is missed.
Receiver and transmitter independently con-
trollable for identification and isolation of ex-
ternal electronic noise sources.
