HNS 3000
In the basic settings, the display can be changed as follows:
• Display of the maximum value "n.TOP"
The highest level measured in the system since the unit was last switched on or since
last performed reset is displayed permanently.
• Display of the minimum value "n.MIN"
The lowest level measured in the system since the unit was last switched on or since
last performed reset is displayed permanently.
• Display of the actual temperature "TEMP"
• Display of the maximum temperature value "T.TOP"
The highest level measured in the system since the unit was last switched on or since
last performed reset is displayed permanently.
• Display of the minimum value "T.MIN"
The lowest temperature measured in the system since the unit was last switched on or
since last performed reset is displayed permanently.
• Display of the set switchpoint "S.P. 1", "S.P. 2", "S.P. 3" or "S.P. 4"
Depending on the model, one of the switch points 1 to 4 can be permanently
displayed.
• Display dark "OFF".
The display is switched off.
Depending on the setting, "n.TOP", "n.MIN", "TEMP", "T.TOP", "T.MIN", "S.P. 1", "S.P. 2",
"S.P. 3" , "S.P. 4" or "oFF" are shown in the display. The ;
scroll through the shown above fluid level and temperature values. If neither of these keys
is pressed within approx. 5 seconds, the value of the parameter pre-set to appear in the
display will be shown.
NOTES:
• If the actual fluid level exceeds the upper limit of the unit's nominal range, it can
no longer be measured and the display starts to flash.
The values of the switching outputs and analogue outputs are maintained. The
measured peak fluid level plus the pre-set offset is shown in the display.
• If, after a voltage breakdown, the display shows "..........." (flashing left and right
centre LEDs), it should be checked whether the tank level is too high or too low.
The analogue output provides 4 mA resp. 0 V depending on the setting of the
analogue input, all switching contacts will be opened.
• If the actual fluid level falls below the lower limit of the unit's nominal range, it
can no longer be measured. The minimum value flashes in the display.
The values of the switching outputs are set to 4 mA or 0 V, all switching
contacts are opened. All switching outputs will be opened.
• If the actual level "niv" has been chosen as a primary display (displayed value
shown permanently), press key
- maximum level value "n.TOP"
- minimum level value "n.MIN"
- current temperature "TEMP"
- maximum temperature "T.TOP"
- minimum temperature "T.MIN"
