When the "+" button is pressed once,
"1.ON" appears on the display until the
control relay has switched on the first
stage after approx. 10 secs provided no
further buttons have been pressed. If the
first stage was already switched on
"1.OFF" will appear on the display until the
control relay has switched off the first
stage after approx. 10 secs. Then the
display will change to the last displayed
value.
While waiting the switching counter of this
stage will be displayed for a short mo-
ment. The displayed value is multiplied by
0.001 and is indicated as far as possible
as a decimal. That means for example:
"0.350" is equivalent to 350 switches.
By pressing the "+" button several times
the stages 2 - 6 will appear in ascending
sequence on the display. They can be
switched on/off in the same way.
By pressing the "-" button once "6.ON"
appears on the display until the control
relay has switched on the 6th stage after
approx. 10 secs. If the 6th stage was al-
ready switched on "6.OFF" will appear on
the display until the control relay has
switched off the 6th stage after approx. 10
secs. Then the display will change to the
last displayed value. By pressing the
"-" button several times the stages 5 - 1
will appear on the display in a descending
sequence. They can be switched on/off in
the same way.
In manual mode, the programmed switch-
ing off time (discharge time) is taken into
consideration, i.e. when switching on a
stage which was previously switched off
the switching-off time is the same as the
discharge time. If a stage was identified as
a zero stage (without power) the
corresponding numbers would indicate
this by flashing.
Press "Man/Set" button to exit manual
mode.
6.3 Alarms
The potential-free alarm contact (a/b)
closes whenever the operating voltage is
not applied. In the case of the correct
operating voltage, the contact closes if
there is an alarm. The conditions for an
alarm can be seen in section 6.3.1 to 6.3.7
below. The LED "alarm" lights up for as
long as a state of alarm exists. When an
alarm is signalised, an alarm marker is put
into action (LEDs "Power Factor", "Am-
pere", or "Harmonic" blink).
The alarm markers remain active after the
alarm until they are acknowledged by
pressing the "Set" button. After acknowl-
edgement the flashing alarm marker goes
out.
The alarm signals have no influence on
the control behaviour/performance of the
relay.
