Hello all,

I work on a PV780 and I want to create a service reminder which every 250 hours, the customer has to change is engine oil.

but I don't know How to make a timer of 250 hours.

I try to do this, but the timer is in (ms)...

If somebody have the solution, it would be brillant!

Thank you.

The Murphy Standard PV780 standard configuration has quite a bit of detail on doing service reminders. The reminder is calculated from the J1939 parameter for the Total Hours of Operation. The color displays do not keep an internal machine hours like the monochrome displays can.

So, the Total Hours of Operation parameter is usually used and not just a 250 hour timer. The Total Hours is compared to the saved service hours to determine if it is time for some action.

Looking at the standard configuration can give you some ideas on how a service reminder can be done:
Using the Total Hours parameter if it is valid.
Setting the reminder target hours.
Compare the target hours to the total hours to determine if a reminder needs to be active.
Set the active indication if the remaining hours is <= 0.

Thanks a lot boyce!

I will try to do this.
