What is displayed Counters are stored in specified time periods (e.g. periodically, daily, monthly, ... see
“Signal analysis”). Here the selection of the counter that is permanently displayed is
made.
Copy set up Copies the settings of the actual channel to the selected channel (including alarm set
points). The last two characters of the channel identifier of the target channel are
substituted by the channel number.
Tip: If the settings for more than one channel are very similar (e.g. more than one
operational time counter) this function makes setting up easier.
Event window “acknowledge”: Displayed message must be acknowledged by operating
the “OK” push button. The message consists of date, time and the relevant event text
L -> H or H -> L.
“Do not display”: There is no event window displayed. The events are however still
entered in the event list (can be called up in normal operation by operating the
function push button “Display”) The event is described with “L->H” or “H->L”
(alternatively an event text L->H / H->L, if this has been set up).
Totaliser/year counter Preset of the totaliser/yearly counter. Useful if the system has previously used an
electro-mechanical counter and the values are to be synchronised.
Attention: The settings only become active when unit set up has been left.
•
Alarm set point: Set-up only required if alarm set point monitoring is required
for this channel.
It is also possible to see if the alarm set point is active without having to open this
menu point (“Limit X active
u
“).
Counter type The alarm set point can be set to various counter types (intermediate, daily, monthly,
total/yearly counters). These counters are regularly reset to zero (exemption: totaliser).
Example daily counter: Daily zero reset after day change. Please note the set-up in
“Signal analysis”.
