Mamba II
ROTARY SWITCH
To accurately sensitivity settings, use the rotary switch 0-9. To set the lowest sensitivity set to 0 and the highest
sensitivity in the range, set 9. If you change sensitivity in the control software, system will store this setting up to next
change using a rotary switch. The last position is always written into an EPROM - whether hardware or software.
To set the detection methods for different types of fences and installing it is necessary to use the programming
software (see. Chapter 4. Programming SW)
3.4. TESTING MODE
The device has a built-in alarm signal level, which will be very helpful for set up of the system. To activate it, turn DIP
switch no. 2 to the ON position.
1
Extra sensitivity
2
Activation of test mode
3
Switch ON / OFF reed relay on mainboard
4-8 Address for RS485 BUS
In this mode, the following LEDs on the board has different meaning:
AL
Alarm
T1
Prealarm
T2
Not used in test mode
Green
Not used in test mode
When adjusting the sensitivity, proceed as follows:
Switch ON Test mode
Turn off extra sensitive mode (DIP switch no. 1).
Set the rotary switch to the middle sensitivity.
Check the signal level by mechanical deformation of sensoring cable. Signal indicator shows the level of signal -
the more green lights on the bar chart means the greater signal level. The yellow LED T1 indicates Prealarm and
red AL indicates an alarm signal.
The sensor needs always 10 seconds after an alarm to regenerate and calibrate the detection algorithm.
Therefore, make individual tests always with a slight time spacing!
Now you can test the sensitivity of the system: throw the object with approximate weight of 2 kg on the fence
(not directly on the cable) and the system should not raise the alarm - red LED AL does not light. Is necessary to
always watch level on the indicator bar.
When the fence is loaded by object with weight more than 25 kg system must raise the alarm - red LED AL lights.
Is necessary to always watch level on the indicator bar.
Adjust the sensitivity by rotary switch or use DIP switch no. 2, until you met the previous two terms.
