Valve outputs | Operating hours counter
During pulse width modulation (PWM) at a valve output, the operating hours
counter only evaluates the switch-on time of the PWM signal.
Image 25: Function of the operating hours counter (using the example of an up-
In the as-delivered state, the operating hour values of all valve outputs of the actuator
is "0". If the operating hours counter is not enabled in the configuration of an output,
no operating hours will be counted for the valve concerned. Once the operating hours
counter is enabled, however, the operating hours will be determined and added up by
the ETS immediately after commissioning the actuator.
If the operating hours counter is subsequently disabled again in the parameters and
the actuator is programmed with this disabling function, all the operating hours previ-
ously counted for the valve output concerned will be deleted. When enabled again,
the meter reading of the operating hours counter is always on "0 h".
The operating hours values (full hours) or operating seconds stored in the device will
not be lost in case of a bus voltage failure or by ETS programming.
On the hour counter: Any summed up operating minutes (full hour not yet reached)
will be rejected in this case, however.
After bus voltage return or after an ETS programming operation, the actuator pass-
ively updates the "Value operating hours counter" communication object in each out-
put. The object value can be read out if the read-flag is set. The object value, de-
pending on the configuration for the automatic transmission, is actively transmitted if
necessary to the KNX once the configured transmission delay has elapsed after bus
voltage return (see "Set transmission behaviour of the operating hours counter").
The operating hours counter detects any operation of the valve outputs in manual op-
eration, which means that switching on an output also activates a counting operation
and the manual switch-off interrupts a counting operation.
No operating hours are counted if the supply voltage of the valves is not switched on.
Activating the operating hours counter
The operating hours counter only counts the operating hours of a valve output if it
was activated in the ETS.
