Commands menu
– The commands menu allows executing some occasional operations like reading peaks resetting, counters clearing, alarms reset, etc.
– If the Advanced level password has been entered, then the commands menu allows executing the automatic operations useful for the device conguration.
– The following table lists the functions available in the commands menu, divided by the access level required.
– With controller in MAN mode, press the MODE button for 5 seconds.
– Press ▲ to select CMD.
– Press MAN-AUT to access the Commands menu.
– Select the desired command with MODE or MAN-AUT.
– Press and hold for three seconds ▲ if you want to execute the selected command. ALPTEC shows OK? with a countdown.
– If you press and hold ▲ until the end of the countdown the command is executed, while if you release the key before the end, the command is canceled.

Alarm description
COD ALARM DESCRIPTION
A01 Undercompensation All the available steps are connected but the cosphi is still more inductive than the setpoint.
A02 Overcompensation All the steps are disconnected but the cosphi is still more capacitive than the setpoint.
A03 Current too low The current owing in the current inputs is lower than minimum measuring range. The plent should be
o-load.
A04 Current too high The current owing in the current inputs is higher than maximum measuring range.
A05 Voltage too low The measured voltage is lower than the threshold set with P.42.
A06 Voltage too high The measured voltage is higher than the threshold set with P.41.
A07 Panel temperature too high The panel temperature is higher than threshold set with P.39.
A08 Capacitor current overload The calculated capacitor current overload is higher than threshold set with P.32 and P.33.
A09 No-Voltage release A no-voltage release has occoured on the line voltage inputs, lasting more than 8ms.
A10 Voltage THD too high The THD of the plant voltage is higher than the threshold set with P.43.
A11 Current THD too high The THD of the plant current is higher than the threshold set with P.44.
A12 Maintenance requested The maintenance interval set with P.45 has elapsed. To reset the alarm use the command C.xx (see
Command menu)
A13 Step failure The residual power of step xx is lower than minimum threshold set with P.40.

Alarms
– When an alarm is generated, the display will show an alarm icon, the code and the description of the alarm in the language selected.
– If the navigation keys in the pages are pressed, the scrolling message showing the alarm indications will disappear momentarily, to reappear again after a
few seconds.
– Alarms are automatically resetted as soon as the alarm conditions that have generated them disappear.
– In the case of one or more alarms, the behaviour of the ALPTEC depends on the properties settings of the active alarms.
