Up / Down Display alarm counter: Down = Query the memory
Up = Query the cumulative alarm time
Displays MAX and MIN measurements, additionally
values
8.5 Menu mode (last decimal point on)
The menu mode is used to select the menu items. If no key is pressed for 30 s, one automatically
returns to the display mode.
Function button
Set / Reset
Press briefly: Change into the configuration mode
Returns to the display mode (the most recently set
values are then applied)
Function key
Up / Down
Press briefly: Select menu item; changes into the display mode
8.6 Configuration mode (last decimal point flashes)
In the configuration mode you can set the value of a parameter. The display alternates between the
parameter relation and the currently set value until one of the Up/Down buttons is pressed, which
changes the value of the parameter. If no key is pressed for 2 s the display starts alternating again.
If no key is pressed for 30 s (simulation mode 15 min) one automatically returns to the display mode (the
most recently set value is applied during this)
Function button
Set / Reset
Press briefly: The settings are taken over; continue to next parameter.
Changes into menu mode after the last parameter
Returns to the display mode (the most recently set
values are then applied)
Function key
Up / Down
Press briefly/long: Value change of the parameter (slow/fast)
Hint: Simultaneously pressing the Up and Down keys resets the adjustable value to zero. If the Up or
Down button is kept pressed while setting the value the change in the display is accelerated.
8.7 Test mode (only activated and connected feedback contacts)
If feedback contacts of the section switch are connected to the UFR1001E and activated (value > set
turn-on time of section switch, e.g. 5.0s), the trip circuit can be tested by pressing the Test button. To do
that, the measurement voltage has to be connected and no alarm is allowed to be present!
After pressing the Test button the UFR1001E triggers. The tripping time of the internal relay + section
switch are measured through the feedback contacts. After successful tripping, the tripping time of the
slower switch remains shown in the display until any key is pressed.
8.8 Alarm counter
The alarm counter 8 8 is increased by 1 with every shut-down. Up to 100 shut-downs are counted.
That allows quick detection of how often the UFR1001E has shut down since the last delete of the alarm
counter (see cumulative alarm time).
Query the alarm counter:
Change into the display mode
Press the button several times until display 8 xx 8
8.9 Cumulative alarm time (display in hours)
The cumulative alarm time 8 8 indicates how long the relay was switched off due to an alarm. It is
recorded with a resolution of 1 minute and only when the control voltage is applied.
