DIABLO DSP-15-LV, VEHICLE DETECTOR
DSP-15 Series, Vehicle Detector
The DSP-15 vehicle detector is the PCB version of our DSP-10 Series.
The DSP-15 vehicle detector has been specifically designed to handle all parking, drive-through and access control applications.
Working on virtually any size loop, the DSP-15 automatically tunes itself to the best operating frequency.
Environmental conditions are constantly compensated with the DSP-15’s HYPERTRACK software.
The DSP-15’s inherent noise filtering algorithms allow it to work reliably in any electrical situation.
x = T = 10-position terminal block.
x = F = 10-pin right angle female Molex
x = M = 10-pin header (model pictured)
Works on any in-ground inductive loop from 20 to 2000 microhenries.
Can be easily changed to fail safe or fail secure mode in the field.
Power interruptions of short duration are ignored. If power fails for approximately three seconds or less the DSP-15 “remembers” a vehicle.
The DSP-15-LV is protected from damage if plugged into a higher voltage. No need to change a fuse or reset a circuit breaker, simply plug the detector into the proper voltage and it works.
Separate Power/Fail and Detect LEDs.
- LED Indicators:
The green POWER LED shows the following status:
Loop Open Slow Flash
Loop shorted Fast Flash
The red DETECT LED shows the following status:
Delay Slow Flash
Extension Fast Flash
No Detect Off
Fail Safe Operation (J2 shunt installed - factory default): In fail safe mode the output A relay is energized and will de-energize for any one of the following conditions: vehicle detection, loop failure, or power failure.
In this mode, continuity will occur between connector/terminal block pins 1 and 3 during detection.
Fail Secure Operation (J2 shunt removed): In fail secure mode the output A relay is de-energized and will energize for either vehicle detection or loop failure.
In this mode, continuity will occur between connector/terminal block pins 1 and 2 during detection.
Switch Settings: Changing any DIP or rotary switch setting automatically resets the detector.
Sensitivity: Experience has shown that almost all parking and access control applications can be handled with sensitivity set at NORMAL (level 5).
The rotary sensitivity switch is rarely moved from NORMAL. However, the DSP-15 has ten sensitivity settings varying from LOW (level 0) to HIGH (level 9).
Frequency: Automatically tunes within one of four operating ranges.
Delay: With DIP switch 1 turned off there is no delay. With DIPSWITCH 1 turned on there is a 2 second delay before output A occurs. This 2 second delay is flashed on the detect LED.
If the vehicle leaves before the two seconds has timed out, the output will not occur. Delay only affects Output A.
Extension: DIP switches 2 and 3 are used to select extension timing. See chart below for extension times. Extension allows the main output to be held for a period of time after the vehicle has left the loop detection area.
Selected extension time is flashed on the call LED. Extension timing only affects Output A.
DIP Switch 2 DIP Switch 3
0 seconds Off Off
2 seconds On Off
5 seconds Off On
10 seconds On On
Sensitivity Boost: DIP switch 4 selects this feature. With switch 4 turned on, sensitivity is automatically boosted during a call to improve detection of high-bed vehicles and truck/trailer combinations.
Sensitivity boost is not applicable to most situations.
Output B Function Select: DIP switches 5 and 6 determine the function of the second output relay, Output B. See chart below to select a specific function.
This output can be used in any one of the following ways:
DIP Switch 5 DIP Switch 6
True Presence Off Off
Entry Pulse On Off
Exit Pulse Off On
Loop Fail On On
True presence: The relay is energized whenever a vehicle is present. The relay is not affected by any delay or extension timing.
Entry pulse: The relay is energized for 250 ms when a vehicle enters the loop, or after the delay interval, if programmed.
Exit pulse: The relay is energized for 250 ms when a vehicle exits the loop or after the extension time, if programmed.
Loop fail: If the inductive loop fails (opens or shorts), the output B relay energizes.
Extended Presence: DIP switch 7 is normally left in the off position. If extended presence is required, this switch is turned on. This feature is only used in those rare cases when a vehicle will be over the loop for a long time (such as a loading dock).
Loop Failure Memory: With DIP switch 8 turned on, the DSP-10 will indicate a prior intermittent loop failure regardless if the failure recovers. Any reset will clear the memory failure.
