4.14 Tactile Modules
The Audible and Tactile power supplies on the ST750LV are designed to provide a DC voltage
between 10V and 24V, and typically provide a maximum of 100mA at 18V DC. The ST750LV
provides three audible activation signals on the pedestrian phases. These are located on the
CPU card PL2 (Phase D) and PL3 (Phase B). Circuit diagram 667/DA/27831/ETC details the
output signals.
Pin 11 is titled ‘Tactile Phase n’ – This is intended to interlock a tactile unit via the tactile PSU
‘interlock’ input to prevent operation on a Pelican during the flashing green man period where the
‘Loud’ output is configured to be time-switched. If the tactile is also required to be switched then
the tactile PSU ‘interlock’ input signal can be taken from this output.
- Tactile Module – P/N 667/7/17390/000.
The Audible and Tactile options are not included in the base Outercase specified in
Table 6, and therefore should be specified separately.
4.15 Regularity Sign Expansion Kit
Fuse position ‘F3 Detector’ can be used to supply regulatory signs if required. Monitoring of any
installed regularity signs would require standard torriodial current coils to be connected to the
external analogue inputs.
4.16 Detector Supply Kits
With reference to Figure 94, the ST750LV is configured with one 2A detector supply kit, fitted on
the right hand side of the ST750LV Rack Assembly, at manufacture. An additional 2A Detector
Supply kits can be specified and fitted immediately below the first. The Detector PSU transformer
of the will be configured with conventional main leads to allow mains supply to be obtained from
the SKT1 on the Phase Driver PCB.
Detector Supply Kits available include:
- 2 Amp Detector Supply Kit (667/1/27853/000)
