Microprocessor Control (MPC) (E-Z Tec V Only)
Eriez’ E-Z Tec Micro Processor
Control (MPC) provides a user
friendly transition from analog
adjustments to digital settings through
a menu–driven digital hierarchy. The
digital screen offers alphanumeric
displays of all preset functions or
reject occurrences as they take place
and also records the date and time of
any changes to the preset settings.
Digital processing and controls on all
E-Z Tec MPC Metal Detectors allow
fast product changes. The active
(present) product can be changed via the
front panel ‘touch’ button or remotely
through the RS–232 or RS–485 com-
puter interface connection.
On–site adjustments and settings are
initiated using a 9–button touch panel
control. A backlit super twist 8–line x
40 character display allows up to 99
different product selections, and the
computer interface allows unlimited
product selections, with each product
selection defining such parameters as
sensitivity, gain, phase, product
description and relay states. Unautho-
rized changes are eliminated by a three
level 4–digit security code. Battery
backup provides memory loss protec-
tion caused by power outages.
The reject menu displays report
number, product, date, time and
magnitude of the reject signal in
millivolts. The internal memory holds
up to 100 reject events for visual
review, or reports can be sent to a local
printer or to a computer via the RS232
and RS485 communications ports or a
separate direct printer output port for
an unlimited record of reject reports.
