MVP D-TEK™ Operating Instructions 4
Document no. 10000104
Reset Switch
When this toggle switch is momentarily pressed down toward the “Frequency Switch” and
released will cause the D-TEK to reboot.
Frequency Switch
This 3-position toggle switch is used to change the loop operation frequency to
High/Medium or Low. This helps to prevent cross talk with adjacent loops and possible
interference from other sources in the same operational frequency. Note: When the
frequency is changed the D-TEK must be re-set.
Frequency Counter
When this toggle switch is momentarily pushed up toward the power and detect LEDs will
cause the detector to blink the red “Detect” LED. Each blink of the LED indicates a
frequency multiple of 10 KHz. (example 5 blinks = 50 KHz.) Counts from 3 to 13 confirm
that the detector has tuned to the loop.
Sensitivity
This rotary switch controls the detector sensitivity. During normal operation the sensitivity
setting is 3 or 4. Note: the higher the sensitivity the more prone the detector will be to
interference. To increase detection height without increasing the detector sensitivity
settings, increase the size of the loop. Detection height is roughly 70% of the shortest side
of the loop. (example 4 x 8 loop = approximately 33 inch detection height and a 6 x 8 loop =
approximately 50 inch detection height.)
ASB
Automatic Sensitivity Boost is activated by DIP switch 6 on the back of the detector. This
allows the detector to be set at a “standby” sensitivity and when detection occurs sets the
sensitivity to maximum until the unit un-detects. This allows for the use on high bed
vehicles that might otherwise un-detect while still in the loop.
Pulse/Presence relay 2
This feature is controlled by DIP switch 2 on the back of the detector and allows relay 2 to
act in the pulse mode or as a second presence mode relay mimicking relay 1.
