Instructions and Warnings
The following indicators and standard definitions are used:
DANGER means that death, severe personal injury, or considerable equipment damage will occur if safety precautions are disregarded.
WARNING means that death, severe personal, or considerable equipment damage could occur if safety precautions are disregarded.
CAUTION means that light personal injury or equipment damage may occur if safety precautions are disregarded. This particularly applies to damage to the device and to
resulting damage of the protected equipment.
WARNING!
The firmware may be upgraded to add new features or enhance/modify existing features, please make sure that the version of this manual is compatible with the product in your hand.
WARNING!
During operation of electrical equipment, certain parts of these devices are under high voltage. Severe personal injury or significant equipment damage could result from improper behavior.
Only qualified personnel should work on this equipment or in the vicinity of this equipment. These personnel must be familiar with all warnings and service procedures described in this manual, as well as safety regulations.
In particular, the general facility and safety regulations for work with high-voltage equipment must be observed. Noncompliance may result in death, injury, or significant equipment damage.
DANGER!
Never allow the current transformer (CT) secondary circuit connected to this equipment to be opened while the primary system is live. Opening the CT circuit will produce a dangerously high voltage.
WARNING!
z Exposed terminals
Do not touch the exposed terminals of this equipment while the power is on, as the high voltage generated is dangerous
z Residual voltage
Hazardous voltage can be present in the DC circuit just after switching off the DC power supply. It takes a few seconds for the voltage to discharge.
PCS-9692C Power Measurement Unit
CAUTION!
z Earth
The earthing terminal of the equipment must be securely earthed
z Operating environment
The equipment must only be used within the range of ambient environment detailed in the specification and in an environment free of abnormal vibration.
z Ratings
Before applying AC voltage and current or the DC power supply to the equipment, check that they conform to the equipment ratings.
z Printed circuit board
Do not attach and remove printed circuit boards when DC power to the equipment is on, as this may cause the equipment to malfunction.
z External circuit
When connecting the output contacts of the equipment to an external circuit, carefully check the supply voltage used in order to prevent the connected circuit from overheating.
z Connection cable
Carefully handle the connection cable without applying excessive force.

Chapter 3 Supervision and Metering Chapter 3 Supervision and Metering
3.1 Overview
When this device is in energizing process before the LED “HEALTHY” is on, this device needs to be checked to ensure there are no errors. Therefore, the automatic supervision function, which checks the health of this device when startup and during normal operation, plays an important role.
This device based on the microprocessor operations is suitable for implementing this automatic supervision function. This device also provides on-line data metering, remote control function.
3.2 Self-supervision
3.2.1 Hardware Supervision
The RAM, ROM, DC/DC and A/D elements on the CPU module are monitored to ensure whether they are damaged or have some errors. If any one of them is detected damaged or having error, this device will be blocked and issues a relevant alarm signal. The LED indicator “HEALTHY” will be extinguished.
3.2.2 Setting Supervision
The settings are checked to ensure them to be correct and not to be modified. If the settings are checked to have any error in them, the alarm signal [Alm_Setting] will be issued and this equipment will be blocked at the same time. The LED indicator “HEALTHY” will be extinguished.
3.2.3 CT Failure Supervision
The main purpose of the current transformer (CT) circuit failure supervision function is to detect faults in the secondary circuits of CT and avoid influence on the operation of corresponding protection functions. This CT failure supervision function will be processed all the time, whether general fault detection picks up or not.
The criteria of CTS element are:
(1) 3I0 > 0.04×In + 0.25×Imax (“I0” is self-calculated)
(2) Imax > 0.04×In
In normal operation program of this device, if the above two conditions are met, and this condition lasts longer than 10s, the alarm signal [Alm_CTS] will be issued and the LED indicator “ALARM” will be lit.
3.2.4 VT Failure Supervision
The voltage transformer supervision (VTS) feature is used to detect failure of the AC voltage inputs to the device.
Chapter 3 Supervision and Metering
The VTS logic in the device is designed to detect the voltage failure and automatically adjust the configuration of protective elements whose stability would otherwise be compromised. A time-delay alarm output is also available.
The criteria of VTS element are:
(1) Any phase current is greater than 0.08In
(2) U1 < 0.31Un or U2 > 0.138Un
In normal operation program of this device, if the above two conditions are met, and this condition lasts longer than 10s, the alarm signal [Alm_VTS] will be issued and the LED indicator “ALARM” will be lit.
3.3 Metering
The device produces a variety of both directly and calculated power system quantities. These measurement values are updated on a per second basis.
The measurands include Ia, Ib, Ic, I1, I2, I0, CTI0, Ua, Ub, Uc, Uab, Ubc, Uca, U1, U2 etc. These measurands are gotten by real-time calculation and real-time summation locally. This calculation is independent with network.
