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 configuration.
– 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.

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 flowing in the current inputs is lower than minimum measuring range. The plent should be
off-load.
A04
Current too high
The current flowing 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.
