OPTIONS (FIGURE 35)
This menu contains adjustments which are rarely
changed.
Buzzer
The MPC sounds a buzzer when a detection
occurs or when any key is pressed. This
feature can be turned off and on via the INCR
and DECR keys.
Setup Communication (Figure 36)
The MPC can communicate to a remote printer
or computer. SETUP COMMUNICATION (Figure
36) is used to configure to a computer. Please
refer to the E-Z Tec MPC Communication Manual
MM-237 for details.
Setup Printer (Figure 37)
Is used to configure to a printer. Please refer to
Appendix A for printer communication information.
Factory
Some metal detector adjustments are performed
at the factory and require no customer access.
These are performed through the Factory menu.
Access requires a confidential password.
Set Time and Date (Figure 38)
The real time clock is set at the factory and should
not require adjustment since the clock is
maintained with battery power when the metal
detector is off. In the event of battery failure or
semi-annual time change, the clock may be set
as follows:
1.
Move the cursor to the desired entry using
the SELECT UP / DOWN keys.
2.
Change the magnitude of the variable with
the INCR and DECR keys.
3.
When the START CLOCK key is pressed the
real-time clock will start according to the
value of the variables on the screen and the
unit will return to the Options Menu.
4.
The CANCEL key will return the unit to the
Options Menu without altering the clock.
Update Passwords (Figure 39)
The password hierarchy is three level, in
increasing order: OPERATOR, SUPERVISOR,
and ENGINEER. All can be changed as follows:
1.
Align the cursor to PASSWORDS in the OP-
TIONS menu and press “GO TO.”
2.
The MPC will respond by asking for a pass-
word. Enter the ENGINEER password.
3.
The MPC will respond with the UPDATE
PASSWORDS menu.
4.
Position the cursor to the desired password us-
ing the SELECT keys and press “GO TO.” The
PASSWORD display of Figure 40 will appear.
5.
Enter the new password with the LEFT, RIGHT,
and ENTER keys. The display will transfer back
to the UPDATE PASSWORDS menu when the
fourth character is selected. Press “EXIT” to
return without changing the password.
Print Options (Figure 41)
The MPC is capable of downloading the detection
reports to a remote printer. Please refer to the
Printer supplementary data (Appendix A) for
further information on PRINT OPTIONS.
DIAGNOSTICS (FIGURE 42)
The Diagnostics menu is intended to give the
operator an easy way to determine the source of
interference which is causing the metal detector to
false trip. Through the Self-Check and Calibration
sub-menus the metal detector can be configured
to self-monitor for proper operation.
Troubleshooting
The oscillator, or transmitter, produces an
electromagnetic field inside the metal detector
aperture and in the vicinity of the aperture openings
outside the metal detector. The receiver monitors the
field produced by the transmitter.
There are three major sources of interference which
can cause the metal detector to false trip: ground
loops, electromagnetic interference, and power line
noise. Follow the guidelines in the table below to
correct the source of the interference causing the
metal detector to false trip.
