Valve outputs | Operating hours counter
The operating hours counter is deactivated.
Deactivation of the operating hours counter and subsequent programming with
the ETS resets the counter status to "0".
Setting type of counter of the operating hours counter
The operating hours counter can optionally be configured as an up-counter or down-
counter. Depending on this type of counter, a limit or start value can be set optionally,
whereby, for example, the operating time of an actuator can be monitored by restrict-
ing the counter range.
Up-counter:
After activating the operating hours counter by enabling in the ETS or by restarting,
the operating hours are counted starting at "0". A maximum of 65,535 hours or
2147483647 can be counted (corresponds to approx. 66 years), after that the counter
stops and signals a counter operation via the "Operating hours count. elapsed" ob-
ject.
A limiting value can be set optionally in the ETS or can be predefined via the commu-
nication object "Limiting value operating hours counter". In this case, the counter op-
eration is signalled to the bus via the "Operating hours count. elapsed" object if the
limiting value is reached, but the meter continues counting - if it is not restarted - up
to the maximum value 65535 and then stops. Only a restart initiates a new counting
operation.
Down-counter:
After enabling the operating hours counter in the ETS, the meter reading is on "0 h"
and the actuator signals a counter operation for the output concerned after the pro-
gramming operation or after bus voltage return via the "Operating hours count.
elapsed" object. Only after a restart is the down-counter set to the maximum value of
65,535 hours or 2147483647 seconds (corresponds to approx. 66 years) and the
counter operation is started.
A start value can be set optionally in the ETS or can be predefined via the communic-
ation object "start value operating hours counter". If a start value is set, the down-
counter is initialised with this value instead of the maximum value after a restart. The
meter then counts the start value downwards by the hour. When the down-counter
reaches the value "0", the counter operation is signalled to the bus via the "Operating
hours count. elapsed" and the counting is stopped. Only a restart initiates a new
counting operation.
The use of the operating hours counter must be set on the parameter page "Ax – Op-
erating hours counter".
￭
Set the parameter "Counting direction" to "Forward". Set the parameter "Spe-
cify signal value" to "via parameter" or "via object" if it is necessary to monitor
the limiting value. Otherwise, reset the parameter to "no". In the "via para-
meter" setting, configure the required limit value (1 ... 2147483647 s or
1 ... 65535 h).
