Function
Description
Time of last switching on and off of the input
voltage
Time is written in UTC format. The next time the
device is turned on or off, the value in the
register is overwritten.
When connecting a three-phase network
Phase break diagnostics in a three-phase
network
2)
If there is no input voltage on any of the three
phases, the red LED on the diagnosed input
lights up. The LEDs of the other inputs of the
group light up yellow. The error value is
recorded in the “Rotation failure or phase
failure” register of the corresponding group.
Phase rotation control in a three-phase
network
1)
If the phase rotation is incorrect, the red LEDs
of these circuit light up, in which the rotation
control occurs. The error value is recorded in
the “Rotation failure or phase failure” register of
the corresponding group.
1)
In case of counter overflow, the register is reset. To reset the counter manually, see
.
2)
Diagnostics is enabled if the module is configured accordingly using the “akYtec Tool Pro”
program or via the Modbus TCP protocol. The module has the ability to connect one to three
control circuits of a three-phase network.
In order to determine the failure when connecting a three-phase network, in the “Network Master”
you need to set up register control for each group of inputs:
–
Voltage at the inputs A1–B1 –...– C3
;
–
Failure of rotation or loss of phases
.
If the phase of any of the input circuits of the group is cut off, the registers will take the values:
–
Failure of rotation or loss of phases
= 1;
– bit of the corresponding input in the register
Voltage at the inputs A1–B1 –...– C3
= 0.
In case of a group phase rotation error, the registers will take the values:
–
Failure of rotation or loss of phases
= 1;
– bit of the corresponding input in the register
Voltage at the inputs A1–B1 –...– C3
= 1.
