32 V 2.3 User manual
9.2.3 Displaying security errors (Info n° 15049)
When a security error occurs, the device will stop functioning. A short text, limited to 8 characters, will
appear on the display indicating which kind of error it is.
* For VS-120 only
9.2.4 Displaying the values of a multi-unit system
When several VarioString units are
connected to the remote control
RCC-02/03, the screen VarioString
MULTI appears, displaying the
consolidated values for all the
connected
equipment. The
displayed values can be selected
as per the same procedure described in chap. 9.2.1.1. Moreover, the units can be viewed one by one by
using the arrows up/down after the SET button (2x) when the VarioString image is with a black background.
9.2.5 Displaying messages and event history
The message system is the same as for an Xtender inverter/charger or a VarioTrack MPPT solar charge
controller and the alarm messages/information are stored and displayed in the same list. See the
RCC remote control user manual.
9.2.5.1
Message list
Warning (000): Battery low: the battery voltage is lower than 40V for more than 30 seconds. The
VarioString continues to work until the battery voltage falls below 18V.
Message (012): Use of battery temperature sensor: this indication is given only if the sensor is
connected to the VarioString when it is energized.
Halted (014): Over temperature EL: the warmest point inside the equipment has exceeded the
allowed highest temperature. The equipment stops operating. It starts again when the temperature
drops back to a normal value.
Halted (020): Battery overvoltage: the battery voltage is higher than 68V. The VarioString turns off. It
starts again when the voltage returns to a normal value.
Warning (081): Earthing fault: the battery earthing does not (anymore) match the selection made by
parameters {14040}, {14041} and {14042} which establishes the type of earthing to be checked.
Text Description
None No error. The unit is fully functional
GroundBat The battery grounding mode is different from that chosen in the parameter settings
(chap. 4.4.1.)
GroundPV The PV grounding in parallel or series mode is different from that chosen in the
parameter settings (chap. 4.4.1).
GroundPV1* The grounding of the MPPT input PV1 is different from that chosen in the parameter
settings (chap. 4.4.1).
GroundPV2* The grounding of the MPPT input PV2 is different from that chosen in the parameter
settings (chap. 4.4.1).
OverTemp An abnormal high temperature is detected (Alarm 014).
OverV_B A battery voltage higher than 68V has been detected (alarm 20).
UnderV_B The battery voltage is too low to start the charger.
OverI_PV A PV voltage over 600V has been detected (on VS-70 or on VS-120 in parallel
mode), or over 900V (VS-120 in series mode) (alarm 82).
OverI_PV1* A PV voltage over 600V has been detected in the MPPT input PV1.
OverI_PV2* A PV voltage over 600V has been detected in the MPPT input PV2.
OverV_PV The max input current has been exceeded (series or parallel cabling).
OverV_PV1* The max input current has been exceeded in PV1.
OverV_PV2* The max input current has been exceeded in PV2.
Cabling* A cabling error has been detected on the PV inputs or the cabling does not
correspond to the selected mode (chap 4.4.1).
