Thermal Overload Supervision; Time Synchronization Supervision; Auxiliary Communication Testing Supervision; Device Maintenance Supervision - NR Electric PCS-9611 Instruction Manual

4 Supervision
[CTS.En] is the logic setting of the CTS element.
If there has no phase current to be led to this relay, the setting [CTS.En] must be set as "0".

4.2.9 Thermal Overload Supervision

See Section 3.4 for the details. When the thermal overload alarm situation is detected, the alarm
signals [Alm_Device] and [49.Alm] will be issued, and the LED indicator "ALARM " will be on at the
same time.

4.2.10 Time Synchronization Supervision

If the time synchronization function is enabled in this relay, but this relay detects the time
synchronization is not correct, the alarm signals [Alm_Device] and [Alm_TimeSyn] will be issued
and the LED indicator "ALARM " will be on at the same time.

4.2.11 Auxiliary Communication Testing Supervision

If this relay is in the auxiliary communication testing of binary signal or metering, the alarm signals
[Alm_Device] and [Alm_CommTest] will be issued and the LED indicator "ALARM " will be on at
the same time.

4.2.12 Device Maintenance Supervision

If this relay is in the maintenance situation (the binary input which is used for denoting
maintenance situation is energized), the alarm signals [Alm_Device] and [Alm_Maintenance] will
be issued and the LED indicator "ALARM " will be on at the same time.

4.2.13 Reserved Programmable Alarm Supervision

The relay provides several reserved programmable alarm signals which can be programmed
through the PCS-Explorer configuration tool auxiliary software according to the engineering
demands. When the relay detects anyone of the reserved programmable alarms is trigged, the
alarm signals [Alm_Device] and [Alm_SpareX] (X: a number; 01, 02 etc.) will be issued and the
LED indicator "ALARM " will be on at the same time.

4.2.14 Tripping Circuit Supervision

The tripping circuit supervision function can be realized by program the logic function of this
device through the PCS-Explorer configuration tool auxiliary software according to the practical
application experience of the user.
In this manual, a scheme which uses two independent binary inputs to supervise the tripping
circuit is recommended.
The following figure show the recommended scheme for tripping circuit supervision and the logic
diagram of the TCS function.
