The detector function defines the basic behaviour of the detector:
- The detector can be set to active or inactive.
- Detector with software-based permanent request: The SOFT detector function generates a software-based permanent request. This permanent request does not work in green. This means that only requests are triggered. A permanent extension must be achieved with the "extension" traffic stream flag.
- The traffic stream is set to red. The REDwJAM detector function is used to check the flow. As soon as the detector in question fulfils the flow control conditions, the assigned traffic stream is set to red. The minimum blocking time after a jam can be parametrised differently to the normal minimum red time. The REDwJAM detector function assumes that a loop is provided in the outflow, i.e. after the stop line. Detectors equipped with the REDwJAM detector function cannot be used for registration and measuring.
- The dimensioning is switched off. The EXTwJAM detector function is used to check the flow. As soon as the detector in question fulfils the conditions of the flow control, the measurement of the assigned traffic stream is switched off. The EXTwJAM detector function assumes that a loop is provided in the outflow, i.e. after the stop line. Detectors equipped with the EXTwJAM detector function cannot be used for registration and dimensioning.
The call mode defines the behaviour when a new request is recognised. For the registration type Occupancy, you must also specify the duration of the occupancy after which a request is recognised. After a request, you can specify how long it is valid. This can be set via the debounce time, delay time, reset time and hold time.

Description |
|
Fct |
Detector function GP |
|
Each detector has a function. |
|
|
|
|
|
|
|
|
INAC |
The detector is switched off. It has no effect. |
|
|
|
NORM |
The detector has no special functionality derived from the detector function. The operation of the detector depends on the detector parameters according to the Standard detector parameters form. |
|
|
|
SOFT |
The SOFT detector function generates a software continuous request. |
|
|
|
The traffic stream is set to red. The REDwJAM detector function is used to perform a flow control. As soon as the relevant detector fulfills the conditions of the flow control, the assigned traffic stream is set to red. The minimum blocking time after congestion can be parameterized differently to the normal minimum red time. Traffic stream is closed immediately in case of congestion. |
|
|
|
|
TS closes only after reaching tgmin1 and jam. |
|
|
|
|
STRO_gmin2 (REDwJAM_gmin2) |
TS does not close until tgmin2 and jam are reached. |
|
|
|
STRO_gmax1 (REDwJAM_gmax1) |
TS closes only after reaching tgmax1 and congestion. |
|
|
|
STRO_gmax2 (REDwJAM_gmax2) |
The TS does not close until tgmax2 and congestion have been reached. |
|
|
|
The extension is switched off. With the EXTwJAM detector function, a flow control is performed. As soon as the relevant detector meets the conditions of the flow control, the extension of the assigned traffic stream is switched off. |
|
|
OCC_TYPE |
Detector call mode |
|
For each detector, it is possible to determine which signal is considered a call. |
|
|
|
|
|
|
|
|
Impulse |
Positive edge: The detector is requested with the rising edge. |
|
|
|
Gap |
Negative edge: The detector is requested with the falling edge. |
|
|
|
mpWithOcc |
Positive edge with occupancy: The detector is requested with the rising edge, or when it is occupied. |
|
|
|
Occupancy |
Occupier: The detector is requested after the occupancy time has been reached. |
|
TREST |
Rest time |
|
Detectors that are processed with pulses can be debounced. This means that no further pulses are accepted after a valid pulse for the duration of the rest time (TREST). |
|
|
|
|
|
|
|
|
0 .. 3276 |
Value in seconds. |
|
TOCC |
Occupancy time |
|
The Occupancy time (TOCC) parameter defines the occupancy time after which the detector requests. |
|
|
|
|
|
|
|
|
no OccTime |
Occupancy is not recorded. |
|
|
|
1 ... 3276 |
This detector is evaluated for occupancy, i.e. it must be occupied for at least the set period of time (in seconds). |
|
|
|
INAC |
The Occupancy time criterion is switched off. |
|
Tdel |
Delay time |
|
The Delay time (Tdel) parameter can be used to delay the effect of a call after the Call criterion has been met. That is, vs | plus waits with a consideration of this requirement until the detector waiting time is greater than the value delay time. |
|
|
|
|
|
|
|
|
0 .. 3276 |
Value in seconds. |
|
Treset |
Reset time |
|
As long as the time after green end is smaller than the comparison value Reset time (Treset), a detector cannot trigger a request. This means that for the duration of the reset time, the requests of the relevant detector are deleted. |
|
|
|
|
|
|
|
|
0 |
No reset. |
|
|
|
1 .. 255 |
Reset time in seconds. |
|
THOLD |
Hold time |
|
The hold time (THOLD) specifies how long the effect of a detector lasts. As soon as the detector waiting time is greater than the Hold time value, the effect of the relevant detector is switched off. In the case of detectors which record the occupancy (registration type occupant) and are set with a hold time of 0s, the effect is only maintained just during the effective occupancy of the detector. |
|
|
|
|
|
|
|
|
Duration |
The detector waiting time is deleted at the start of green or at PT check-out. |
|
|
|
0 .. 3276 |
Holding time in seconds. |
