To enable the feature that indicates to the user when a filter change is due Pr 6.18 should be set to the time between filter changes. When the drive is
running, Pr 6.27 is reduced each time the runtime timer hour increments (Pr 6.23) until Pr 6.27 reaches 0, at which point Pr 6.19 is set to 1 to inform
the user that a filter change is required. When the user has changed the filter, resetting Pr 6.19 to 0 will indicate to the drive that the change has been
done and Pr 6.27 will be reloaded with the value of Pr 6.18. Pr 6.27 can be updated with the value of Pr 6.18 at any time by setting and clearing this
parameter manually. If Pr 6.18=0, then Pr 6.27 is held at zero and so parameters should be saved after Pr 6.18 has been setup so that this system will
function correctly after the drive is powered down and powered up again.

The powered-up clock always starts at zero each time the drive is powered-up. The time can be changed by the user from the keypad, serial comms
or an application module. If the data is not written with the various parts in the correct range (i.e. minutes are greater than 59, etc.) the clock is set to
zero on the next minute. This clock may be used for time stamping the trip log if Pr 6.28 = 0.

The run time clock increments when the drive inverter is active to indicate the number of minutes that the drive has been running since leaving the
Control Techniques factory. This clock may be used for time stamping the trip log if Pr 6.28 = 1.
