No Heart Beat
Communication
cable
broken or control board
without response.
Contact Cinergia in order to
isolate the problem.
13
PLL error
The frequency of the grid is
too high or low.
Check the grid frequency.
14
Mains lost
There is no voltage on the
grid (short interruption or
voltage dip).
Check the grid voltage.
15
Open loop
The power supply has
reached
the
maximum
voltage in current or power
operation mode.
The load is not connected or its
impedance is too high for the
current setpoint.
16
Isolation
The isolation detector has
detected a fault in the
galvanic isolation.
Check if isolation fault disappears
when the power supply has no
load connected to the output. If it
does, the isolation problem is in
the load. If it does not, contact
Cinergia.
17
Overload
The
power
supply
is
working beyond its rated
values.
Check the parameters configured.
18
Shortcircuit
The power supply has
detected a shortcircuit in
the equipment under test
Check the equipment under test
impedance.

Alarms reset
The user shall follow the next steps for resetting the alarms:
Press the emergency stop button.
Send a Reset signal to the power supply.
Send a Not enable and Not run signals (note: this step is done automatically when the
user is interfacing the power supply by the LCD or by the software provided by
Cinergia).
Proceed as a standard start-up process by deactivating the emergency stop (pull out
the button).
A Reset will be performed only in the case that the alarm source has been cleared. If the
problem persists after resetting the power supply, a new alarm will be triggered.
