III. FUNCTIONAL PARAMETER SETTING
The parameters of the Walk-through Metal Detector (WTMD)
can be set according to the requirement. The parameter set-
ting is password protected and therefore the parameter setting
menu can only be shown after the password is input correctly.
Figure 6~13 shows the input password. The “SEL” is used
for selection password digits, while the “ADJ” is used to for
changing any selected digit. the “ENT” shall be pressed to
enter the password
.
The initial password of the parameter setting interface is
“1234”, which can be changed by the user. The system has
been provided with a universal password of “1111”, which is
always available. The user can enter the interface with this
password if the customized one is forgotten. After the user en-
ters the interface with the password of ”1111”, the customized
one will become “1234” automatically.
The password used for system setting is “1264” (for important
parameter settings), the user can enter the system setting
menu after this password is input.
The interface will show Fig.40 when an incorrect password
inputted. Input the correct password again at the password
interface.

modication menu, see Fig. 26.
(2) Press “SEL” to select password digits. The digit can be changed by pressing “ADJ” until the 4-digit password is set,
see Fig. 33. The password will be modied successfully after “ENT” is pressed (The password is not saved in the
system though modied successfully, save the set new password according to the “III 4 Save set parameter “).
(3) After the password is modied, see Fig. 34, the password input interface still exists (being equivalent to Fig. 5), the
user can enter the setting menu after the correct password (modied) is input.
2. Sensitivity setting
Input the correct customized password or “1111” and press “ENT” to show Fig. 14. Press “ENT” to enter the parameter set-
ting menu, see Fig. 15.
(1) Press “SEL” to select the submenu (L001~ L008). L001~ L006 refer to the sensitivity of zone l ~ 6. Taking L001
as an example, see Fig. 41 ~ 44, press “ADJ” to select the sensitivity digits. The selected digit can be changed by
pressing “ENT”. After the sensitivity of zone 1 is set, press “SEL” to enter the sensitivity setting menu of zone 2.
(2) The sensitivity from zone 1 to 6 can be set separately or set as the same one for the sake of convenience. L007
refers to all sensitivity values from zone 1 to 6, which can be set as the same one by specifying L007 as an non
zero value, e.g. when L007 is set as 150, then the sensitivity from zone 1 to 6 can be Level 150 after the setting is
saved. If it is unnecessary to set the sensitivity as the same one, L007 must be set as 000.
(3) L008 refers to the multiple of the integral sensitivity. The “Once” or “50 times” can be selected. The switching
between “Once” and “50 times” can be enabled by pressing “ADJ”. The “ENT” is unnecessary here. If “Once” is
selected, the sensitivity will not change; If “50 times” is selected, the sensitivity will be reduced by 50 times.
Note: The adjustable levels with regard to sensitivity are restricted within Level 0 ~ 999. The higher the value is,
the higher the sensitivity will become; The higher the multiple of is, the lower the sensitivity will become.
3. Alarm setting
Input the correct password or” 1111” and press “ENT” to show Fig. 14, then press “SEL” to enter the alarm setting menu,
see Fig. 15. Press “SEL” continuously to enter the ring tone setting menu (see Fig. 24 or Fig.45), the last two digits of
the lower row digital tube are shown, where the rst one the ring tone (9 ring tones i.e. Ring Tone 1 ~ 9 are optional),
the second digit means the volume (Volume 0 ~ 8 are optional, Volume 0 means mute). The “ADJ”and “ENT” are used
for selecting digits and changing selected digit.
13
www.2MTechnology.net
2M Technolgy User Manual
Ringer volume set and press “SEL” is shown in Fig. 25 (or Fig. 46), enter the alarm time settings, 0.5S ~ 4.0S adjustable
alarm time, press “ADJ” to change the time, in increments of 0.5S, It will return 0.5S after more than 4s.
4. Set parameter saving
The parameter will become effective immediately after setting, however it is only available for current operation. When the
machine is shutdown and started again, the operation of the system will enabled based upon the last saved parameter.
Only those set parameter saved in the system are always effective.
Method for saving set parameters: After a parameter is set, press “ENT” in the interface showing “d001”
(see Fig. 25 or Fig.46), the parameter will be saved in the system. After the parameter is saved, the main interface will
be shown automatically (see Fig. 1). The number of passed persons and alarms will be reset.
IV. SYSTEM PARAMETER SETTING
1. Manual frequency setting
Input the password of “1264” and press “ENT” to show Fig. 35. Press “SEL” to enter the manual frequency setting menu,
see Fig. 36.
Press “ADJ” to select the frequency digit. The selected digit can be changed by pressing “ENT”.
The manual frequency setting, taking lHz as one stepping, is allowed within 7000 ~ 8999Hz. When the frequency is about
8000Hz, the system performs the best and the power consumption is the lowest.
Note: When the frequency is about 8000Hz, the system performs the best. Generally, the frequency shall be kept
within 7350 ~ 8700Hz.
2. Automatic frequency setting after startup
“Automatic frequency setting after startup”: The system will check the frequencies of ambient machines automatically in
order to set different frequency. When more than one WTMDs is used at the same time, the frequency of each one can be
staggered automatically for fear of repeat and high mutual interference during the operation.
Setting method: Enter the interface as shown in Fig. 37. The automatic frequency setting after startup will be unavail-
able when the last digit of the lower row is “O” and available when “l “; The “ADJ” can be used for switching the last digit
between “O” and “l “. The nal setting shall be saved in the system.
Note: When more than one WTMDs is to be used at the same time, just shut down them after the automatic fre-
quency setting nishes and then start them in order. The frequency setting of one machine must be nished
before the next one is started; Different frequencies shall match with different ring tones.
3. Filtering mode setting
Enter the password “1264” and press Key “ENT”, as shown in Fig. 35; press key “SEL” for three times to enter into the l-
tering mode setting menu, as shown in Fig. 38, and the ltering mode is shown in the last digit at lower row, with the corre-
sponding relationship being shown as below:
0–Band-passltering: it can lter out interference by high frequency and low frequency.
1–Highpassltering: it can lter out low-frequency drift interference by.
2–Lowpassltering: it can lter out the high-frequency interference.
3–Noltering: original data is not subject to ltering treatment.
The Key “ADJ” makes the ltering mode switch circularly under four kinds of modes.
Notes: ltering mode can lter out interference and reduce false alarm. However, after ltering, there will be signal delay
and alarm delay. Band-pass ltering can achieve the best result, but it also lead to the longest time delay. This function de-
14 www.2MTechnology.net
Walkthrough Metal Detector with Single Wrist Thermal Sensor 2MTHWT-HMD
pends on surrounding environment, if there is only small interference, then ltering can be omitted. When more (more
than 4) Walk-through Metal Detector (WTMD)s are working at the same time, there will be certain interference, thus caus-
ing false alarm, so ltering mode is necessary.
4. Set parameter saving or restore to factory settings
“SEL” “Save set parameters” or “restore factory settings” in the interface showing “dOO l”
(see Fig. 38).
0 – Set parameter saving
When the last digit of the lower row is 0, just press “ENT”, the set “Frequency” and the parameter determining automatic
frequency setting will be saved in the system, which will be available for the next startup.
1 – Factory setting restoring
When the last digit of the lower row is 1, just press “ENT”, all factory settings will be restored and saved by the system.
The main interface will be shown again after the saving (Fig. 1). The number of passed persons and alarms will be reset.
DETECTION ADJUSTMENT
I. The Walk-through Metal Detector (WTMD) can only meet the highest performance under stable
conditions. Steps for checking the Walk-through Metal Detector (WTMD) for being used under sta-
ble conditions:
1. Check the installation position of the Walk-through Metal Detector (WTMD) for meeting the requirement of
“installation condition”.
2. The Walk-through Metal Detector (WTMD) shall not waggle after startup.
3. The alarm is not triggered when the tester without metal articles passes through the WTMD; The alarm is triggered
when the tester with metal articles (e.g. keys) passes through the WTMD.
4. The Walk-through Metal Detector (WTMD) can be considered as being used under stable conditions when meeting the
above items.
II . In order to prevent personal belongs such as rings, keys, buckles, leather shoes with metal
parts etc. from affecting those metal articles required to be detected, the following adjustment
steps shall be conducted:
1. Increase the sensitivity, the alarm shall be triggered when passing the WTMD with those metal article exceptions;
2. Decrease the sensitivity (within an appropriate range), pass the Walk-through Metal Detector (WTMD) again with those
metal article exceptions until the sensitivity is just decreased to the level causing no alarms.
Note: If the sensitivity of one zone is required to be decreased, just adjust the relevant zone; If the sensitivity of the
entire WTMD is required to be decrease, just set “All” as an non-zero value to realize the setting of all 6 zones or set
the “Integral” as 50 times. After the above adjustment, those articles with the sizes being smaller than the sample
will not trigger the alarm, while those with the sizes being bigger than the sample will be detected accurately.
III. Inspection rules of the Walk-through Metal Detector {WTMD)
1. A warning line being 50 cm away from the front / rear of the Walk-through Metal Detector (WTMD) shall be drawn in
order to make the persons to be inspected pass one by one.
2. Before the persons to be inspected passes the WTMD, those carried metal articles such as keys, cell phone, iron trade
mark articles, cigarette and coins etc. shall be put at a specied position. The above mentioned articles can be taken
back after the inspection.
3. The persons to be inspected shall walk through the WTMD, normally one by one. Crowdin g, intended rush or ambling
15
www.2MTechnology.net
2M Technolgy User Manual
as well as impacting the door plate are not allowed.
4. For the WTMD inspection, the person shall be inspected after the last one passes the warning line without triggering
the alarm. If an alarm is triggered, the person shall be inspected after the alarm tone stops.
5. A person passing through the Walk-through Metal Detector (WTMD) triggers the alarm means that metal articles are
carried. The metal article location can be found according to the indication of the LED light bar (The bought “Hand met-
al detector” produced by our company can used together).
6. The person to be inspected shall not wear jewelries or clothes, caps and footwear with metallics for fear of affecting
normal inspection of metal articles.
COMMON PROBLEM HANDLING
I. Infrared sensor counting failure
1. Check both ends of the sensor leads in the main case for being correctly connected.
2. If both ends of the sensor leads are connected correctly, check the emission voltage of the infrared modules for being
in good condition. Resistor R5 and R286 are emission ends. The voltage R5 / R286 and U2 / U36 connecting ends is
approx. 2.5V. D2 and D13 are reception ends. When the infrared is not blocked, the voltage of the 3rd pin of D2 and
Dl 3 is close to OV. When the infrared is blocked, the voltage of the 3rd is higher than 3V. If the voltage of the infrared
module emission and reception ends is normal, check IC U21 of the main controller.
3. If one or a pair of the infrared module emission and reception ends does not work, the infrared tube shall be checked
for being burnt or bad connection or the system for bad wiring.
II. False alarm
1. If frequent false alarm appear, check the installation conditions of the Walk-through Metal Detector (WTMD) for meeting
the “Installation conditions”.
2. If the installation meets the “Installation conditions”, check the right / left door plates for being installed backwards.
3. If the door plates are installed correctly, try to decrease the sensitivity of all zones and check the false alarm for being
handled.
4. If this problem is still not handled through decreasing sensitivity, check the voltage for being normal. Normal working
voltage shall be 110 - 240V. False alarms might be caused if the voltage is lower than 11OV (handling method: Try to
buy an adjustable booster or a back-up UPS power supply).
5. If the working voltage is kept within the normal range, check the oscillation frequency for being normal. Stagger the
interference by changing the frequency and the perform further tests.
III. Startup failure
1. If a startup failure appears, check the voltage for being kept within a normal range. If the supply voltage is lower than
90V, the machine will not be started up (Try to buy an adjustable booster).
2. If the voltage is kept within a normal range, check the input end of the switching supply. If no voltage is found, check the
fuse for being burnt out. If the voltage is normal, check the output end voltage of the switching supply for being 12V. If
the voltage is 12V, check the voltage values of the motherboard and MCU for being 5V and 3.6V respectively.
IV. Alarm failure
1. If an alarm failure occurs, check the alarming mode rstly. If the alarming mode is “With infrared”, the alarm is only
available with infrared counting; If the alarming mode is “Without infrared”, check the oscillation signal for normal out-
put.
16 www.2MTechnology.net
Walkthrough Metal Detector with Single Wrist Thermal Sensor 2MTHWT-HMD
2. If the alarm failure still exists though the oscillation signal is normal, the DC power values of the motherboard shall be
checked for being +8V, -8V and +12V respectively with a multimeter.
3. If the DC power values of the motherboard are +8V, -8V and +12V, the reference voltage shall be checked for being
3.6V with a multimeter.
4. If the reference voltage is 3.6V, the 3rd-pin DC voltage of Q21 and Q25 of the motherboard shall be checked for being
close to -8V and OV respectively with a multimeter.
