6.3.2 Control functions shutdown
If the Control Function Lockdown is active, the controller will operate only as a voltage indicator, while
leaving the output relay off.
This feature is managed by the function ‘‘
[,F22]
-
Control function shutdown’’
:
[,,no]
Control functions shutdown disabled
[,,,1]
Control functions shutdown enabled if the functions lockdown is not active
[,,,2]
Control functions shutdown always enabled
After the Control Functions Shutdown has been enabled, to activate it, the user must use the Quick menu
key and navigate it to
[Ctrl]
, then confirm the selection with the set key. After the user confirmed the
selection, the messages

6.5.1Parameters description
F01 - Number of phases in operation:
This parameter configures which phases will be monitored by the instrument:
[,,,1]
- Only the R phase (used in single-phase connections)
[,,,2]
- R and S phases (used in two-phase connections)
[,,,3]
- R, S and T phases (used in three-phase star connections)
[,,,4]
- R, S and T phases (used in three-phase triangle connections)
F02 - Detection of phase inversion:
This parameter enables/disables the phase sequence monitoring. If this function is enabled and a phase
has been inverted, the output relay will remain open and an alarm will be set, thereby protecting the load
against possible phase inversions.
Note:
Protection against phase inversion is only available if
[,F01]
is set to the value 3 or 4.
F03 - Angular asymmetry sensitivity:
This parameter adjusts the sensitivity with which the
PhaseLog
e
plus
will detect phase angle
asymmetries. The higher the value of this parameter, the lower will be the tolerance against this
error. If you wish to disable this monitoring, simply set the function with the value 0.
The equation to determine the detection limits of the alarm is presented in chapter 8.2 - Detection of
angular / modular asymmetry alarms. It should be noted that the limits to indicate angular asymmetry
error are given by "mean of the lags + tolerance" and "mean of the lags - tolerance". In this way, it is
important to note that the alarm detection limit depends on the current values of each measured
phase. To illustrate, knowing that the phase difference between two voltage phases in a three-phase
system is ± 120 ° and the total sum of the phase-shifts is equal to 360 °, if the function is set to the
value
[,f03]
= 80, then we have:
- Upper limit: the alarm will be triggered when the angular mismatch is greater than 144º.
- Lower limit: the alarm will be triggered when the angular mismatch is less than 96º.
F04 - Time to validate angular asymmetry:
Time in seconds that the three-phase monitor waits to validate the angular asymmetry error.
F05 - Modular asymmetry sensitivity:
On this parameter the user can adjust the sensitivity with which
PhaseLog
e
plus
will detect the
phase asymmetry of the phases set in
[,f01]
. The higher the value of this parameter, easier the
controller will detect the error. If you wish to deactivate this monitoring, simply set the function to
00.0.
The equation for determining the detection limits of the alarm is presented in chapter 8.2 - Detection
of angular / modular asymmetry alarms. It should be noted that the limits to indicate modular
asymmetry error are given by "mean of the vo tolerance" and "mean of the voltages -
tolerance". In this way, it is important to note that the alarm detection limit depends on the current
values of each measured phase.
For example, considering that the function is set to the value
[,F05]
= 80 and that the voltages of
the phases R and S are equal to 220 V
RMS
, then:
- Upper limit: the alarm will be triggered when the phase T voltage is higher than 293 V
RMS
, because
it will be higher than the mean of the measured values (244 V
RMS
) plus the calculated tolerance (48
V
RMS
).
- Lower limit: the alarm will be triggered when the phase T voltage is less than 159 V
RMS
, because it
will be less than the average of the measured values (199 V
RMS
) less the calculated tolerance (39
V
RMS
).
F06 - Time to validate modular asymmetry:
Time in seconds that the three-phase monitor waits to validate the modular asymmetry error.
F07 - Minimum operating voltage:
Minimum voltage threshold to trigger the out-of-range alarm and open the load relay.
F08 - Maximum operating voltage:
Maximum voltage threshold to trigger the out-of-range alarm and open the load relay.
F09 - Time for validation of out of range voltage:
Time in seconds that the three-phase monitor waits to validate the out of range voltage alarms
(
[,F07]
/
[,F08]
).
Note:
If there is any error in the voltage reading (
[E-t,]
,
[E-r,]
or
[E-s,]
active), this function is
ignored, therefore the output is disabled immediately.
F10 - Offset of R voltage indication:
This parameter lets you adjust the R phase voltage indication offset.
F11 - Offset of S voltage indication:
This parameter lets you adjust the S phase voltage indication offset.
F12 - Offset of T voltage indication:
This parameter lets you adjust the T phase voltage indication offset.
F13 - Delay to energize the controller:
Time in seconds in wish the
PhaseLog
e
plus
will wait before triggering its output.
F13 - Delay to enable load output during controller startup:
Time in seconds that the
PhaseLog
e
plus
will wait before activating its load output during startup.
F14 - Minimum time to reactivate load output:
Time in seconds that the
PhaseLog
e
plus
will wait before reactivating its load output once it has
been deactivated.
F15 - Data logger operating mode:
This parameter controls the datalogger operating mode:
[,,,0]
- Always off
[,,,1]
- Always on
[,,,2]
- Manual operation
F16 - Datalogger sample period
Period of time in seconds between each voltage sample stored in the controller's datalogger.
F17 - Force datalogger write on voltage change
If the datalogger has been activated and if any monitored voltage suffers a change greater than ou equal
to the value set in this parameter, the
PhaseLog
e
plus
will force a data recording in memory
regardless of the sampling time set in F16. This functions is evaluated once per second. This function
can be set from 3 to 50 volts; to deactivate it, press the
<
key until the
[Off,]
message appears on
the display.
NOTICE:
The controller is equipped with a an auxiliary internal power supply in order to keep its date and time in the case
of an energy shortage.A fully charged battery can provide enough energy to keep the time and date running for
some weeks. If the controller remains turned off for a prolonged period of time, it will display the
message
[ECLO]
; in this case the controller's date and time has been lost due to low battery and the user must
adjust it again. To completely recharge a dischaged battery, keep the controller turned on for at least 5 hours.
