TRAM PRIORITY OPERATION
TRAM |  | Function |  |  |  |  |  |  |  |  |  |  |  |  |  |
Detector No |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
6 | - | Starts Timer 1 (Refer Special Purpose Timesettings Nos. 9, 13, 23 & 27) |
7 | - | When first activated resets Timer 1 |
8 | - | Starts Timer 2 (Refer Special Purpose Timesettings Nos. 10, 14, 24 & 28) |
9 | - | When first activated resets Timer 2 |
Timer 1 or 2 expired OR detectors 8 or 10 'ON' constitutes a 'TRAM CALL' |
NOTES: |  |  |  |  |
1. When an advance tram detector fails (ie has a detector alarm) it will be ignored. |  |  |
2. When a stop line tram detector fails, both it and the associated advance detector will be ignored. |  |
3. If the value of a delay timer is set too high (eg. 200 sec.) the tram will reach the stop line loop well before the
delay timer expires, and thus phase calls from the advance detector will effectively be inhibited. |  |
4. Timer status can be monitored by observing the LED display on the front panel as follows: |  |  |
Controller Type |  | Key Command |  |  |  | LED Position & Timer No |  |
|  |  |  |  |  | o | o | o | o | o | o | o | o |  |
Delta 3 |  | A.128 |  |  |  |  | 4 | 3 | 2 | 1 |  |
PTF3 |  | A.4128 |  |  |  |  | 4 | 3 | 2 | 1 |
PSC |  | A.E0128 |  |  |  | 1 | 2 | 3 | 4 |  |  |  |  |
5. Tram calls are cancelled and timers reset if the timers have been expired for more than one cycle. |
6. To monitor XSF and MSS flags on the front panels, key in: |
Controller Type |  | XSF | MSS |  |
Delta 3 |  | A.D8 | A.DA |  |
PTF3 |  | A.40D8 | A.40DA |  |  |
PSC |  | A.E00D8 | A.E00DA |
Z Flags |  | Period | Select Alternate Delay Times |  | Select Special Timer Times |  | Inhibit Detectors |
No | Z- | No | Z+ |  | L.O.P | 9 - 10 |  | 11 - 12 |  | - |  |
| Z- | No | Z+ |  | A.M. | 13 - 14 |  | 15 - 16 |  | - |
No | Z- |  | Z+ |  | P.M. | 23 - 24 |  | 25 - 26 |  | - |
| Z- |  | Z+ |  | H.O.P. | 27 - 28 |  | 29 - 30 |  | - |
7. Tram leaving detector 7 sets MSS1. |
8. Tram leaving detector 9 sets MSS2. |
9. When XSF4 (Master & Flexi) is set, the pedestrian delay by trams is inhibited - Pedestrian Operation |
notes (page 3/1) are not applicable. |
10. When XSF4 (Master & Flexi) is set, the tram detectors (Timer 1 or 2 expired or Detectors 8 or 10 on) extend
SG1 & SG2 in A, B, D and E phases the same as the vehicle detectors. The timers are reset when either the
associated stopline tram loop is activated or if the timers have been expired for more than one cycle. |
