8. The Smart Touch Controller automatically governs frequency selection for all Hy5A detector modules.
This simplies installation and guarantees that there is no cross-talk
between multiple loops. The frequency and call level can also be
manually selected; if this is required, refer to the appropriate loop
set
( ELD, ILD, OLD, RLD) in the Installer Menu: Table 6 on page 66.
9. Sensitivity is the only adjustment available on the detector itself.
Generally, sensitivity does not need to be increased unless the loop
is large or there are multiple loops connected to one detector.
NOTE: Do not exceed more than 200 square feet (61 square meters) of loop area
to one detector. The detection height is roughly 2/3’s the size of the shortest side
of the loop.
If required, adjust the sensitivity using the rotary dial. The factory
default setting is 1.
0 = Low with boost* 4 = Low without boost
1 = Normal with boost* 5 = Normal without boost
2 = Medium with boost* 6 = Medium without boost
3 = High with boost* 7 = High without boost
NOTE: *A boost feature is applied for settings 0 through 3. Boost increases the sensitivity during a call and is
useful for maintaining continuous detection if the signal becomes weak (such as with tractor-trailer trucks).
Sensitivity settings 4 through 7 are the same as 0 through 3, but without the boost feature.
10. Set the loop congurations in the Installer Menu. Display settings include, DT, OR, IR, DL.
11. Set the vehicle detector logic (DL).
View Call Level in Real Time
1. Enter the Installer Menu and access the loop menu item associated with the Hy5A detector:
Exit=ELD, Inside=ILD, Outside=OLD, or Reset/Shadow/Center=SLD/CLD).
2. Press SELECT and change the menu item to 2, Call Level. For example:
ILD2
CALL LEVEL
3. To exit the Installer Menu and return to Run mode, press Menu.
Knowing the strength of a vehicle detector (call level) is valuable because it provides information about how
well the vehicle loop is actually “seeing” a passing vehicle. The Hy5A detector has the ability to read call levels
in real time on a scale of 1 to 7. A call level of 7 indicates the loop is detecting the passing vehicle extremely
well and is highly sensitive. If you receive a call level reading of 0 to 2, when a vehicle passes over the loop,
you’ll want to test the loop to make sure is functioning correctly. If the test outcome is good and
all the loops are operating properly, you may need to adjust the Hy5A sensitivity dial, so the call level reads in
the 5 to 6 range.
