Carryfast said;The two different types shown here.They both used totally different charts because they used a different type of trace reading.So we generally had to carry both types of charts incase we had to use different vehicles and the other different spigot mounting type for Veeder Root.
I might be wrong, I often am, but the two photos both show ‘Automatic’ Tachographs.
The clue is in the word ‘Automatic’ displayed on the instrument panel. Additionally, the mode switch for the driver record has only three positions; ‘work,’ ‘availability’ and ‘break/rest.’ Irrespective of what the driver set the mode switch to, the Tachograph would ‘automatically’ show a driving mode trace when the instrument received impulses or ‘turns’ from the gearbox sender unit. If the Tachographs had been ‘manual’ types then the driver mode switch would have four positions available; ‘driving,’ ‘availability,’ ‘work’ and ‘break rest.’
The one with the square mounting plate fitted to the front is a model 1318, it used to be the most numerous unit out there. However, the fact that we’ve had digital Tachographs required by law since 2006 means that crown has now been taken by the 1327 (VDO digital Tachograph). The other Tachograph looks like a Lucas Kienzel 1311, using a Bowden cable drive rather than electrical impulses from a Hall Effect motion sensor.
You’re right about carrying different types of chart but there were many types. Some related to the shape of the drive peg on the chart table. Some related to whether the chart was for ‘automatic’ or ‘manual’ Tachographs. Others related to the maximum speed recorded by the Tachograph. Ask drivers doing France how much fun it was in France with an early Actos fitted with a 90 Km/h Tachograph (VDO 1319) when they were using a 125 Km/h chart and having a chat with the Gendarmes. There were even ‘universal’ charts, but they weren’t often as universal as people thought!
Here endeth the next Tachograph lesson.
I know I posted a correct one.
I was confused by the driving symbol which at face value reminded me of the manual type and missed/didn’t bother looking for the automatic label.The rest all stands.
Automatic and Veeder Root different with their own quirks.
The Veeder Root was a nightmare if the clock and mounting ‘key’ got dropped on the floor at night let alone lost or no charts for it.
The automatic as stated again different charts and putting a duty line where a driving line should be.
It looks like nothing has changed regarding the latter except now it’s even worse booking break when it should be booking driving.
