results in more rapid regulation (with larger steps in the value). Once the value of the parameter has
been changed, the changed value flashes and the "SET" push-button must be pressed to save the new
setting; a TIMEOUT (10 seconds) with no user acting on the push-buttons cancels the change in the
value and the value before the change is displayed again.
To exit the settings menu, press the "SET" button key for at least 5 seconds or wait for the TIMEOUT
(30 seconds) without pressing any push-button.
The parameters relevant to the control algorithm are:
D
URATION BEFORE DISCONNECTION
Allows setting of the duration of instantaneous power above the "power threshold +
hysteresis" value before the device initiates the load tripping procedure; the local buzzer
is also activated during the countdown of the duration.
VALUES: from 1 to 240 seconds with step of 1 sec. for fine regulation/10 sec. for rapid
regulation, 1 (default value for IEC 62962 application)
T
RIPPING LOGIC
Allows the load tripping logic to be set.
VALUES: 1 (from lowest priority to highest priority), 2 (from greatest demand to least
demand, default value), 3 (from least demand to highest demand)
C
ONNECTING LOGIC
Allows the load connecting logic to be set.
VALUES: 1 (as tripping logic), 2 (opposite to tripping logic, default value), 3 (manual
reconnection only)
M
ANUAL PRIORITY
Allows manual load connection priority with respect to the tripping performed by the
device to be activated or deactivated.
VALUES: On, Off (default value)
T
HRESHOLD VALUE
Allows the value of the power threshold used by the load control function to be set.
VALUES: from 0.00 kW to 8.00 kW with step of 0.01 kW for fine regulation/0.10 kW for
rapid regulation, 3.30 kW (default value)
T
HRESHOLD HYSTERESIS
Allows the hysteresis value for the power threshold used by the load control function to
be set.
VALUES: from 0.01 kW to 2.50 kW with step of 0.01 kW for fine regulation/0.10 kW for
rapid regulation, 0.50 kW (default value)
