Display Of Measurements And Required Cosϕ Setting; Maximum Value Clearing; Operating Mode - Icar 5LSA Bedienungsanleitung

1.12 DISPLAY OF MEASUREMENTS AND REQUIRED COSϕ SETTING
Normally, the display shows the cosϕ of the system together with the IND and CAP
LED's. The flashing decimal point indicates the negative sign (inverse energy flow).
By pressing the MODE key, the V, A, ∆kvar, etc. LEDs are switched on one after another
and the relative measurement of each is shown.
An optional function is available for each LED and indicated on the front panel, which can
be displayed by pressing the + and - keys (the LED flashes quickly thereafter).
When the SET COSϕ LED lights up, the set-point of the required cosϕ can be pro-
grammed; the + and - keys increase or decrease the value respectively. The set cosϕ can
be adjusted between 0.80 IND and 0.80 CAP.
The following table summarises all the available measurements.

This PF (Power Factor) value is determined by active and reactive energy meters of
the last 7 days. It is referred to positive energy quadrants only.
Overload current (Thd I %) caused by harmonic voltage at the capacitor terminals.
Caution! The temperature measurement is considered valid after a period of 20-30
minutes after power up.

1.13 MAXIMUM VALUE CLEARING

The maximum values of Voltage, Current, Overload and Temperature along with average
weekly power factor can be cleared by simultaneously pressing the + and - keys for 3 sec-
onds. Once clearing is complete, the display views CLr.

1.14 OPERATING MODE

The AUTO and MANU LED's indicate the automatic or manual operating mode.
To change mode, press the MANU/AUTO key for at least 1 second.
When the SET COSϕ LED is lit up, no mode change is possible.
The operating mode remains stored even if power is removed.
