A use question about Jobo process timer 8

[yexiaoxiao2102]

Hi,

Does Jobo process timer 8 need to be connected to the Jobo CPP/CPA machines in order to work? I recently bought one and its screen won't lit up even I connect it to the wall outlet. And the seller told me that it needs to be plugged into the Jobo machine?

Thanks!

I have never used one, but I knew someone who had the timer 4, which is essentially the same thing.

The above brochure in French I have in English, there is no mention of it needing to be attached to a processor, in fact I don't know how it would be attached to a processor. What you could do is obtain the accessory foot switch so that you can keep your hands free to do the processing steps required. That is the pédale art. number 6201 in the bottom right corner of AgX's attachment.

The process timer 8 is a more advanced unit, perhaps there is an internal fuse that has blown. Being in the USA is it not possible it may have been attached to 115V instead of 230V or vice versa?

Well, there may be some connection to a Jobo processor indeed...

There is a "sensor" (#4615) to be mounted at any Jobo lift. And to be connected to Process Timer 16 (brother model to the #8). That is the timer where one can start the run-down by either a start button or ones voice (handsfree thus). Jobo do not explain the function of that sensor, but to me it s clear that it just gives a start signal for each process step run-down to the timer (basically a 2nd switch in parallel to the start switch).

Maybe #8 has a socket for the cable of this sensor too

AgX, I found a reference in a Jobo publication dated 8/92 which mentions the Jobo timer 16. This timer is fully programmable, can be operated by keys or sound (voice control)...

with additional Lift sensor which may be controlled automatically from the processor. Also suitable for older lifts.

Timer 16 item number 4610
Lift-Sensor item number 4615.

Well, only the start of each timer run-down can be trickled by loud voice (or rather sound), so much on "operating". And nothing more this sensor could do. (Something a tinkerer with a microswitch, cable and little soldering could make himself.)
