S-1200 Series Specications
This is a basic performance specication and is not intended to be used as operating instructions.
GENERAL CHARACTERISTICS:
Loop Frequency: The LCD screen displays the actual loop operating frequency for each
channel which makes it easy to quickly identify and eliminate crosstalk in the most difcult to congure intersections. There are eight (8) selectable loop frequency settings per channel (normally in the range of 20 to 100 kilohertz). The actual loop operating frequency is a function of the loop / lead-in network and the components of the loop oscillator circuit.
Sensitivity: A unique bar-graph displayed on the LCD makes it easy to quickly set sensitivity at the ideal level for any loop / lead-in network situation. There are nine (9) selectable sensitivity levels per channel, plus settings for Continuous-Call and Channel-Off. See SENSITIVITY, -∆L/L, & RESPONSE TIME table.
Continuous-Call: When set to the Continuous-Call state, the channel output is continuously in the Call state regardless of the presence or absence of vehicles over the loop. The loop oscillator is disabled when in the Continuous-Call state. This state is indicated by CALL ashing on the LCD. This option is selected from the Sensitivity menu in Program Mode and is useful for checking controller response and other troubleshooting activities.
Channel-Off: When set to the Channel-Off state, the channel output is continuously in the No-Call state regardless of the presence or absence of vehicles over the loop. The loop oscillator is disabled when in the Channel-Off state. This state is indicated by OFF ashing on the LCD. This option is selected from the Sensitivity menu in Program Mode and is useful for checking controller response and other troubleshooting activities.
Call Delay: Each channel’s Call Delay is adjustable from 0 to 255 seconds in one-second steps. Call Delay time begins when a vehicle enters the loop detection zone. The remaining Call Delay time is continuously displayed on the LCD. Whenever a Phase Green Input (call delay override) signal (pin J of either channel’s front panel mounted connector) is active (high state), the Call Delay function for that channel is aborted and the Call Delay time is forced to zero.
Call Extension: Each channel’s Call Extension is adjustable from 0 to 25.5 seconds in 0.1­second steps. Extension time begins when the last vehicle clears the loop detection zone. The remaining Extension time is continuously displayed on the LCD. Any vehicle entering the loop detection zone during the Extension time returns the channel to the Detect state, and later, when the last vehicle clears the loop detection zone, the full Extension time starts counting down again. NOTE: See Option 3, Call Extension Control for an alternate mode of operation for Call Extension.
Presence / Pulse: One of two mutually exclusive modes of operation for each channel can be selected in Program Mode:
Presence Mode: Provides a minimum Call hold time of at least four minutes (regardless of vehicle size) and typically one to three hours for an automobile or truck.
Pulse Mode: A single output Pulse of 125 ±10 milliseconds duration is generated for each vehicle entering the loop detection zone. Each detected vehicle is instantly tuned out if it remains in the loop detection zone longer than two seconds. This enables detection of subsequent vehicles entering the loop detection zone. After each vehicle leaves the loop detection zone, the channel resumes full sensitivity within 0.5 seconds.
Max Presence Timer: Each channel’s Max Presence timer is adjustable from 0 to 999 seconds in one-second steps. A setting of zero (0) turns the Max Presence timer OFF. The Max Presence function is used to limit presence time by automatically resetting a channel. If this function is enabled (ON), the Max Presence timer begins counting down when a Call is initiated and the remaining time is continuously displayed on the LCD. If the loop becomes vacant before the Max Presence timer reaches zero, the Call is dropped and no automatic reset occurs. If the End-Of-Green (EOG) function is not enabled (OFF) and the Call is still present when the Max Presence timer reaches zero, the channel is then automatically reset. If the EOG function is enabled (ON) and the Call is still present when the Max Presence timer reaches zero, the channel enters a Wait state. The Wait state continues until the loop becomes vacant; or the Phase Green Input signal for the channel (pin J of either channel’s front panel mounted connector) transitions from green to not green with the Call still present. If the loop becomes vacant rst, the Call is dropped and no automatic reset occurs. If the Phase Green Input for the channel transitions from green to not green while the channel is in a Wait state, the channel is automatically reset. The phase green signals on pin J are also called Call Delay Overrides.
End-Of-Green (EOG): The EOG function is used to synchronize a channel reset with the termination of the associated phase green. The EOG function is only available when the Max Presence function is set between 1 and 999 seconds. It is not available when the Max Presence function is OFF. When the EOG function is enabled (ON), the channel will automatically reset at the time the phase green input signal (pin J of either channel’s front panel mounted connector) transitions from the ON state to the OFF state if the Max Presence Time has counted down to zero and is resting in the Wait state. The phase green signals on pin J are also called Call Delay Overrides. If an out of range loop failure condition exists and is identied (i.e. loop inductance is less than 20 microhenries or greater than 2500 microhenries) the detector channel will not be reset at End-of Green and the channel will remain in the failed state.
Option 1, Loop Inductance Display: When this option is enabled (ON), the LCD screen displays the total loop inductance (actual loop inductance plus actual lead-in inductance) in microhenries for loop inductance values in the range of 20 to 2500 microhenries. NOTE: Enabling this option activates it for both channels. This option is automatically disabled 15 minutes after activation or on loss of power.
Option 2, Loop Inductance -∆L/L Display: When this option is enabled (ON), the LCD screen displays the percentage of inductance change (-∆L/L value) during the Call state. To facilitate viewing of the maximum change in the -∆L/L value while trafc is in motion over the detection zone, the detector will hold the peak -∆L/L value for a period of two seconds. NOTE: Enabling this option activates it for both channels. This option is automatically disabled 15 minutes after activation or on loss of power.
Option 3, Call Extension Control: When this option is enabled (ON), the channel will extend calls for the programmed extension time only when the Phase Green Input signal (pin J of either channel’s front panel mounted connector) is active for the channel. When this option is OFF, the channel extends ALL calls for the programmed extension time. The signals on pin J are also called Call Delay Overrides. NOTE: Each channel can be enabled independently.
Option 4, Noise Filter Disable: When Option 4 is enabled (ON), internal noise ltering is disabled thus providing a faster response time. When this option is OFF, internal noise ltering is utilized. When the detector is used in speed and/or occupancy applications, the noise lter should be disabled (i.e. Option 4 ON) to provide the most accurate data possible. It is recommended that this option not be activated. The factory default setting of OFF provides stable operation in high crosstalk environments. NOTE: Enabling this option activates it for both channels. Changing the setting of this feature will reset both channels. See SENSITIVITY,
-∆L/L, & RESPONSE TIME table.
Option 5, Phase Green Loop Compensation: When Option 5 is enabled (ON), normal loop compensation is used until the Phase Green Input signal (pin J of either channel’s front panel mounted connector) becomes active. Once the Phase Green Input signal is active, concurrent with a call output, the detector desensitizes the loop by 0.05% (-∆L/L) over a 15 second period. This desensitization tunes out small changes, such as adjacent lane pickup, therefore minimizing the chance of max timing an empty lane. A small motorcycle may also be tuned out following the start of Phase Green. This option is useful in minimizing the effects of false detection from adjacent lane pickup when a channel must be run with a high sensitivity setting to ensure detection of motorcycles. When Option 5 is not enabled (OFF), normal loop compensation is used. NOTE: Each channel can be enabled independently.
Option 6.0, Vehicle Counting Display (TrueCountTM Models - See Model Numbers Table): When Option 6.0 is enabled (ON) for a channel, the normal
operating display is replaced with the accumulated vehicle count display. Each channel is capable of accumulating 65,535 counts before rolling over to zero. The LCD display will show just the hundreds, tens, and ones digits until the accumulated count exceeds 999. At this point the LCD display will alternate between the ten thousands and thousands digits and the remaining three digits for hundreds, tens, and ones.
Option 6.1, Counter Reset: This setting is used to reset the accumulated count for the selected channel. When Option 6.1 is changed from the OFF state to the ON state, the accumulated count for the selected channel is reset to zero. Option
6.1 will always be in the OFF state when rst viewed.
Option 7.00, Vehicle Counting Loop Conguration (TrueCountTM Models ­See Model Numbers Table): Each channel’s Vehicle Counting Loop Conguration
setting can be set from 7.01 to 7.05. This setting indicates the number of loops installed in a single lane. Option 7.01 would indicate a single 6’ x 6’ loop or a long loop such as a 6’ x 50’ QuadrupoleTM. The remaining four settings indicate the number of 6’ x 6’ loops installed in a single lane of trafc. NOTE: Refer to the Model S-1200 Series Operation Manual for complete installation and operation details.
Option 9, Third Car Passage: Option 9 is a paired channel option. This means that it takes two channels to implement this feature. When Option 9 is enabled (ON), the outputs of the paired channels 1 and 2 are logically ANDed together. This means that while the loops for both of the paired channels are occupied, a call will be output on both channels. While only one loop is occupied, or neither loop is occupied, a call will not be output on either channel. The rst channel with detection will enter a pending state while waiting for detection on the other paired channel. While in the pending state, the LCD will show Pnd on the display. This feature is intended to be used in Protected / Permissive left turn situations. The expected installation is a stop bar loop for the left turn lane connected to one channel, a queue detection loop for the left turn lane connected to the other channel with a small amount of delay time programmed, and the output of either channel connected to the Vehicle Call input for the protected movement of the trafc controller. NOTE: Refer to the Model S-1200 Series Operation Manual for complete installation and operation details.

S-1200 Series Specications
Option 10, Directional Logic: Option 10 is a paired channel option. This means that it takes
two channels to implement this feature. When Option 10 is enabled (ON), directional logic is enabled. Directional logic starts with a detection on one of the paired channels. This channel will go into the pending state, display Pnd on the LCD screen, and NOT output a call. When both of the paired channels have detection, the last channel to have detection will output a Call until the detection for the last channel ends, even if the detection ends for the rst channel. None of the timing functions (Delay, Extension, Max Presence, or Detector Disconnect) of the rst channel with a detection will time and the rst channel will always operate in the Presence Mode regardless of programming for the channel. The second channel with a detection will time all timing functions as programmed.
This feature is intended to be used in parking lot applications where vehicles can enter or exit from the same lane, freeway ramps for wrong way detection, and left turn lanes where other movements in the intersection tend to clip the detection zone of the left turn. The expected installation is two loops, one after the other in the same lane, spaced anywhere from slightly overlapping to six feet apart. NOTE: Refer to the Model S-1200 Series Operation Manual for complete installation and operation details.
Option 11, Audible Detect Signal: When this option is enabled (ON), an audible signal will be activated whenever the detection zone for the selected channel is occupied. The audible signal indicates actual occupancy of the loop detection zone. Timing and disconnect functions have no affect on the audible signal. This feature allows a technician to watch the detection zone on the street and conrm correct detector operation without having to look at the detector display as well. Only one channel can have this feature active at a given time. Turning this option on for one channel automatically turns it off for the other channel. NOTE: This option is automatically disabled 15 minutes after activation or on loss of power.
Option 12.0, Detector Disconnect: The Detector Disconnect feature requires that the Phase Green Inputs for each channel be connected to the proper controller phase. When the Phase Green Input is not active (low), the detector shall operate normally. When the Phase Green Input is active (high), at the end of each detection, the extension timer will start to count down. If this timer reaches zero before the next detection, this channel will no longer output a Call until the phase green input is not active. Because the extension timer is used as a disconnect timer while in this mode, two different disconnect types are available:
Option 12.1 OFF: Extension timing occurs and the extension timer also serves as the disconnect timer during phase green. This will cause the Call output to remain in the Call state until disconnect occurs. This may allow the user to use gap times appropriate for the advanced loops without considering the effects on the stop bar loops.
Option 12.1 ON: Extension timing is disabled and the extension timer is used as the disconnect timer. This will cause the Call output to follow the occupancy of the loop detection zone until disconnect occurs.
This feature is intended to be used in applications where a loop at the stop bar is not needed after any waiting queue in the associated trafc lane is moving during the green. Note: Refer to the Model S-1200 Series Operation Manual for complete installation and operation details.

Loop Feeder Length: Up to 5000 feet (1500 m) maximum with proper feeder cable and
appropriate loops.
SPECIFICATIONS (ELECTRICAL):
Power: 89 to 135 VAC, 50/60 Hz, 4.8 Watts maximum.
Loop Inductance Range: 20 to 2500 microhenries with a Q factor of 5 or greater.
Loop Inputs: Transformer isolated. The minimum capacitance added by the detector is
0.068 microfarads.
Lightning Protection: Meets and/or exceeds all applicable NEMA TS 1 specications for transient voltage protection. The detector can tolerate, without damage, a 10 microfarad capacitor charged to 2,000 volts being discharged directly into the loop input terminals, or a 10 microfarad capacitor charged to 2,000 volts being discharged between either loop terminal and earth ground.
Reset: Meets and/or exceeds NEMA TS 1 detector specications. The detector can be reset by removing and reapplying power. Both channels are reset by changing the setting of Option 4 (Noise Filter Disable). Each channel can be independently reset by pressing the CHAN button until the desired channel is selected, then holding the CHAN button for three seconds. Also, changing either the sensitivity or loop frequency of a channel will reset that channel. NOTE: Resetting a channel or changing the setting of Option 4 does not disable any selectable diagnostic functions. If any diagnostic option(s) (Option 1, Option 2, or Option 11) has (have) been activated, it (they) will remain activated following the channel reset or change of Option 4 setting. Resetting the detector by removing and reapplying power disables all selectable diagnostic features.
Phase Green Inputs: Also known as Call Delay Overrides. Meets and/or exceeds all NEMA TS 1 requirements. Application of a high state voltage (89 to 135 VAC) to pin J of either channel’s front panel mounted connector causes the delay timer for the channel to abort the delay timing function and also provides control for Phase Green Loop Compensation, Max Presence Timing (End-of-Green), Extension Timing, and Detector Disconnect, if the features are programmed.
Solid State Output Ratings: Optically isolated. 30 VDC maximum collector (drain) to emitter (source). 100 mA maximum saturation current. 2 VDC maximum transistor saturation voltage. The output is protected with a 33-volt Zener diode connected between the collector (drain) and emitter (source).

SPECIFICATIONS (OPERATIONAL):
Display: The LCD back-lighting illuminates whenever any push-button is pressed.
The back-lighting will extinguish 15 minutes after the last actuation of any push­button.
Detect Indicators: Each channel has a super-high-intensity, red, light-emitting­diode (LED) to indicate a Call output, Delay Timing, Extension Timing, Pending state, or failed loop.
Response Time: Meets and/or exceeds NEMA TS 1 response time specications. See SENSITIVITY, -∆L/L, & RESPONSE TIME table for actual response times.
Self-Tuning: The detector automatically tunes and is operational within two seconds after application of power or after being reset. Full sensitivity and hold time require 30 seconds of operation.
Environmental & Tracking: The detector is fully self-compensating for environmental changes and loop drift over the full temperature range and the entire loop inductance range.
Grounded Loop Operation: The loop isolation transformer allows operation with poor quality loops (which may include one short to ground at a single point).
Loop (Fail) Monitor: If the total inductance of the channel’s loop input network goes out of the range specied for the detector, or rapidly changes by more than ±25%, the channel will immediately enter the Fail-Safe mode and display LOOP FAIL on the LCD. The type of loop failure will also be displayed as L lo (for -25% change or shorted loop conditions) or L hi (for +25% change or open loop conditions). This will continue as long as the loop fault exists. However, if the detector is reset, or power is momentarily lost, the detector will retune if the loop inductance is within the acceptable range. If any type of loop failure occurs in one (or more) loop(s) in a group of two or more loops wired in parallel, the detector will not respond with a Fail-Safe output following any type of reset. It is essential that multiple loops wired to a common detector channel always be wired in series to ensure Fail-Safe operation under all circumstances. At the time of a loop failure, the channel’s LED will begin to ash at a rate of three ashes per second. The LED will continue this display pattern until the channel is manually reset or power is removed. If the loop self-heals, the LOOP FAIL message on the LCD will extinguish and the channel will resume operation in a normal manner; except the LED will continue the three ashes per second display pattern, thus providing an alert that a prior Loop Fail condition has occurred. Each loop failure for the channel is counted and accumulated into the Loop Fail Memory. The total number of loop failures written into the Loop Fail Memory (since the last power interruption or channel reset) is viewed by stepping through the channel’s functions in Program Mode until the LOOP FAIL message is displayed.
Full Restore To Factory Defaults: Pressing and holding all four front panel switches simultaneously and continuously for ve seconds resets the detector and restores all the factory default settings. The countdown of the ve-second period is displayed on the LCD screen. Releasing any of the switches before the countdown ends will abort the Full Restore operation. See FACTORY DEFAULT SETTINGS table.
Display Test: Pressing any two or three of the front panel switches simultaneously will display all possible symbols and messages on the LCD screen.

Note: Entries in this table are based on the assumption that both detector channels are set to the same sensitivity. To achieve the exact response times listed above, the Sensitiv­ity of both channels must be set the same. To approximate response times for a detector with channels set to different sensitivities, look up the response time for each channel and divide it by two, then add these times together.
