Comparing projects is a very useful function, which enables you to check differences between two projects.The ITC-PC software is a multi window software and it is possible to open more then one project. If more than one project is open, you can compare them. Mark two of the opened projects from the menu (1) or from the tool bar pressing the compare button (2). Software generates a list of differences (3). Double clicking on any of the differ- ences will show you the exact place in the configuratoin where the specific difference was found (4).

It is a very detailed log, describing in details what was send and received to/from the controller and if there where any difficulties. Whenever you have a problem with communicating with the controller check the Log file first. The log file lists all functions sent to the controller (1). It also shows the whole package (2) sent to the controller and the response from the controller (3) ACK (package accepted) or NAK (package not accepted for example because of wrong checksum).

15 APPENDIX III - Mains supervision
15.1 Mains voltage [V]
The page ”Mains [V]” gives some additional mains voltage supervision options. It is based on two sections: basic and advanced, designated for those who wants to achieve a very precise and strict level of supervising mains voltage.
Figure 265: Mains
15.2 Minimum mains voltage 0-255 V
The controller switches instantly to the failure mode with dark lamps, when the mains voltage drops below this value and the duration of the voltage dip is equal or longer than specied in F993N4. The controller remains in this mode until the mains voltage again has been a least 5 seconds. A programmed value of zero disables this function.
Figure 266: Minimum mains voltage
15.3 Maximum mains voltage 0-300 V
The controller switch instantly to the failure mode with dark lamps when the mains voltage is above this value. The fault will be cleared again when the mains voltage has been inside the interval between the minimum and maximum for more than 10 seconds. A value of zero will disable the checking of maximum voltage.
Figure 267: Maximum mains voltage
15.4 Mains supply frequency 50-60
The mains frequency can be set to 50 or 60 Hz.
Figure 268: Mains supply frequency
15.5 Mains voltage dip duration 0-40
The value is given in 20 ms resolution. A value of zero will internally be considered as 60 ms.
Figure 269: Mains voltage dip duration
15.6 Auxiliary mains voltage 0-255
An extra mains voltage value can be defined to achieve a state in which a fall in mains voltage below this value will force the controller into a controlled shut-down mode (see also F999N41). Flashing yellow will be displayed in failure mode if not F993N1 is set to dark failure mode (+2). The value must be above the minimum value defined in parameter F993N2. A value of zero disables this function
Figure 270: Auxiliary mains voltage
15.7 Mains frequency limit (critical) 0-20
The controller will switch to the failure mode when the mains frequency variation is more than the +/- limit. The fault will be cleared again when the frequency has been within the limit for at least 10 seconds. A value of zero will disable this function.
Figure 271: Mains frequency limit
15.8 Mains frequency limit 0-20
The controller will set a fault when the mains frequency variation is more than the +/- limit. The fault will be cleared again when the frequency has been inside the limit for at least 10 seconds. A value of zero will disable this function.
Figure 272: Mains frequency limit

18 EXAMPLE I
18.1 Intersection layout
The interaction has 6 vehicle groups (G1, G2, G3, G4, G5 and G6) and 3 pedestrian groups (P1, P2, P3). There are 4 loop detectors (D1, D2, D3, D4) on the main road and 4 video detectors on the side roads (C1, C2, C3, C4). Video detectors connects to the digital input terminal. The pedestrian push buttons (P1, P2, P3) connects to the Aux/Red2.
Figure 291: Intersection layout
The Stage Sequence contains both main and alternative stages (A, B1, B2, C, D and E).
18.2 Step 1 Intersection layout
First switch the graphical mode and type the intersection name, Backplane ID, number of signal groups, plans etc. See: Quick Start View button section 3.5 page 17
Figure 292: STEP 1
See: STEP 1 - Intersection layout section 4.1 page 18
18.3 Step 2 Signal groups
Click STEP 2 button and decide the signal groups name, type and min group sequence.
Figure 293: STEP 2
See: STEP 2 - Signal groups section 4.3 page 25
18.4 Step 3 Conflicts
Fill in the intergreen time matrix with the values from the traffic design. Values should always consider the local traffic regulations, speed and distances.
Figure 294: STEP 3
See: STEP 3 - Minimum inter green time matrix section 4.4 page 29
18.5 Step 4 Conflicting group numbers
Table from STEP 4 contains conflicting group numbers
Figure 295: STEP 4
See: STEP 4 - Signal group conflicts section 4.4 page 31
18.6 Step 5 Start-up sequence
Choose start-up sequences from the list - different for the vehicle and pedestrian signal groups.
Figure 296: STEP 5
See: STEP 5 - Intersection start-up sequence section 4.6 page 32
18.7 Step 6 General plan programming
Make the signal plans ”isolated type” and decide the star-up and rest stage. To learn more about: - start-up stage definition see: Start-up stage section 4.7.3 page 34 - rest stage definition see: Rest stage programming section 6.1.1 page 89
Figure 297: STEP 6
See: STEP 6 - General plan programming section 4.7 page 33
18.8 Step 7 Lamp supervision programming
See: STEP 7 - Lamp supervision section 4.8 page 36
18.9 Step 8 Intergreen time matrix
The Intergreen time marix from STEP 8 usually contains both physical and logical conflicts - more about logical conflicts in section 4.9.2 page 41
Figure 298: STEP 8
See: STEP 8 - Physical and fictive inter green time matrix section 4.9 page 40
18.10 Step 9 General plan programming
The plan drawing represents the traffic design. If your traffic design contains only the tabular representation of the green times, you can draw it on your own here in STEP 9. When the drawing plan structure in STEP 9, consider both the green times and stage sequence.
Figure 299: STEP 9
Here you should consider the main stages only. Don’t draw any alternative stages here. How it is decided that the stage B2 is a main stage and the B1 is an alternative one? Simply, if we made the B1 main stage then groups P8 and P9 would never get green as these groups don’t belong to any other stage but only to B2. That is why the B2 stage is a main stage. And only if the P8 either P9 is not requesting, controller can create the alternative stage B1, with the left turn G4 green two times, in stage B1 and E2.
See: STEP 9 - Traffic plans programming section 4.10 page 43
18.11 Step 11 Stage sequence
The Stage Sequence usually contains programming for main stages only. You don’t have to program the alternative stages here. Alternative stages will be created by the controller auto- matically, following some additional rules programmed in the Detector Logic.
Figure 300: STEP 11
See: STEP 11 - Stage logic programming section 4.12 page 55
18.12 Step 13 Loop detector hardware programming
The software generates the default loop detector hardware programming.
Figure 301: STEP 13
See: STEP 13 - Loop detectors section 5.1 page 66
18.13 Step 14 Detector Logic
The Detector Logic programming links loop and video detectors with vehicle groups:
Figure 302: STEP 14 - loop detectors and digital inputs
The Detector Logic programming links the push button inputs with pedestrian signal groups:
Figure 303: STEP 14 - push buttons
See: STEP 14 - Detector Logics section 5.2 page 68
18.14 Step 10 Sequence Logic programming
Press the ”vehicle actuated” button and change the default fixed time settings to vehicle ac- tuated.
Figure 304: STEP 10
You can also add Sequence Logic in STEP 1, make it fixed time plan and associate with Plan 3. This way first two plans would remains vehicle actuated and the last one fixed time plan (back up plan).
