CAUTION!
Digital input is based on dry contact detection principle. Never apply signal to inputs. Otherwise there is risk of damaging
the device.
Digital input type (tYPE):
„
Option to enable tariff 2 (TARIFF 2): If you choose this option for the digital input type, tariff2 energy counters
will be enabled when the digital input is active (dry contact must be applied from related DIN+ and DIN-).
„
Option to enable the counter (COUNTER): If you choose this option for the digital input type, the counter will
count the changes in the position of the digital input depending on the chosen detection edge.
„
If you choose rising edge detection (RISING) for the detection edge, the counter will increase by 1 on each
activation of the dry contact that is connected to the digital input.
„
If you choose falling edge detection (FALLING) for the detection edge, the counter will increase by 1 on each
de-activation of the dry contact that is connected to the digital input.
„
If you choose both edges detection (BOTH EDGE) for the detection edge, the counter will increase by 1 on
each activation and de-activaton of the dry contact that is connected to the digital input.
„
Run Hour enable option (RUN HOUR): If you choose this option for the digital input type, the “run hour
counter” start counting when the digital input is active. (Dry contact must be applied from related DIN+ and
DIN-).
Detection delay time (dLY):
The input is enabled or disabled based on the detection delay time which is set to account for contact spikes or
noise in the digital input.
Detection edge (EdgE):
Use this menu item to choose the position where the digital input is detected active or passive. This menu is
available only for the digital input mode “counter”. Other options always use the rising edge detection.
3.5.7 Pulse Output Settings Menu (PULSE)
Use this menu item to specify the on/off position, output parameter, pulse duration and step range settings for
the pulse outputs. You can freely choose the settings for each pulse output independent of each other. Please
see Table 3-3 for the menu tree and SECTION 5 for the factory default settings.
The pulse output is activated with an increase in the predefined output parameter that is equal to each step range
and deactivates after the predefined time.
Output parameter setup (OUT):
Use this menu item to set the parameter dependency of the output. The respective output is closed when you
choose “OFF”.
Pulse duration setup (durA):
Use this menu item to specify the time the pulse is active.
Pulse step range (rAt):
Use this menu to specify the smallest possible increase for the input parameter that will
output a pulse.
3.5.8 Password Settings Menu (SECURITY)
Use this menu item to turn the password protection on/off, set a password activation time and change password
settings editing options. Please see Table 3-3 for the menu tree and SECTION 5 for the factory default settings.
4 digit password protects the product setup and counter menus against unauthorized access and modifications.
When activated, a password query screen is displayed if someone attempts to change the values. After a successful
login, the device will not ask for a password until the “password activation time” has elapsed. You can set this value in
the respective menu item. Please see Table 3-3 for the menu tree and SECTION 5 for the factory default settings.
