•OP RATION & OV RVI W
The P9680
P9680 P9680
P9680 (from the P9600 series family of IDMT/DT relays) is a mi ropro essor based relay
designed to monitor and dete t Over urrent on individual phases and non-dire tional Earth faults (by
measurement of the neutral urrent) in 3-phase appli ations. Typi ally the P9680
P9680 P9680
P9680 is wired in
onjun tion with external urrent transformers of the feeder to be prote ted.
A lear ba klit LCD provides all key information the user requires for both operation and setting up.
Setting is a hieved in a few simple steps and requires no previous knowledge of produ t operation.
Normal operation provides the user with a tual live individual phase urrents and earth fault urrent
all on one s reen. The a tual phase urrent represents that of the urrent passing through the
primary side of the externally onne ted CT’s. This is a hieved by the setting of the ratio for the CT.
Programming mode allows the user to assign the operation mode for both internal relays. They an
be individually assigned to Over urrent, Earth fault or a ombination of both. They an also be
onfigured for Auto or Manual resetting. Relay 2 has the added option of being allowed to energise
at the start or end of a time out period. If assigned to energise at the start, the Relay an be used to
operate a buzzer or lamp giving early warning before a system a tually shuts down.
Low-set and High-set thresholds an be programmed for both Over urrent and Earth fault
dete tion. The time urrent hara teristi of the low-set units are sele table between Normal
Inverse urve 3/10, Normal Inverse urve 1.3/10, Long Time Inverse urve, Very Inverse urve,
Extremely Inverse urve, Extremely Inverse 0.65 urve and Definite Time. High-set units are the
Definitive Time type. Instantaneous tripping is possible by setting the time to minimum.
Two simple Summary s reens are displayed on e the programming is omplete. The same s reens
an also be displayed by presses of the “R S T” button. This allows the user to a ess key
information with the tamperproof transparent over losed and sealed.
A Test mode is provided (also a essible with tamperproof transparent over losed) to onfirm the
orre t operation of the internal relays. The relays will energise when the “T ST” button is pressed
and de-energise when the button is released (AUTO Reset) or when the “R S T” button is pressed
(MAN Reset).
Following a trip ondition, the information about the trip is then stored. This an then be re alled
later if required using the “R S T” button to a ess the information. The P9680
P9680P9680
P9680 has the ability to
store up to 10 trips and using the “Up” and “Down” buttons, allows ea h trip to be displayed
individually. Ea h trip is also marked with a time stamp showing the time from power up as well as
the time from the previous trip. This feature is very useful for establishing a pattern on parti ular
inputs, knowing when they o urred and how frequent!

P9680 is arried out using the 3 buttons lo ated
behind the transparent over.
The button sele ts the required parameter to be hanged. The
buttons either in rement or de rement a value a ordingly.
Any adjustments made are stored by the pressing and holding of the button
until the LCD shows the word “Saved!

 Please read the “Notes during programming” before commencing with the
following.
1A. TOROID RATIO
 Setting the Toroid Ratio will allow the “actual” Phase currents (IL1, IL , IL3) and
Neutral current (Io) displayed on the LCD to represent that of the currents flowing
through the external CT’s. If no CT’s are used, the parameter should be set to 5/5
(i.e. 1:1). The setting applies to all CT’s.
 Default setting is “5/5”
•Press and hold the button. The LCD displays a s reen showing the

The information displayed highlights the ause of the trip (i.e. whi h phase for example), the level of urrent at the time the trip o urred; the triggering method (Low-set
or High-set) and whi h relays were a tivated. It also shows the elapsed time from powering the P9680

relay is set for Manual resetting, then pressing the “RESET”
“RESET”“RESET”
“RESET” button will de-energise the
relay(s) and clear the LCD.
In the event of an Overcurrent condition, the basic sequence of events is
shown below.
 Assuming High-set trip is enabled.
2. ARTH FAULT
•When an Earth fault o urs ausing a flow in urrent through the Neutral, an
in rease in urrent reading on the LCD will o ur. When the level of urrent
ex eeds the Low-set setting, the reading will be highlighted by the digits
flashing.
•The LCD ba klight will flash.
•Relay 2 will energise if assigned to Earth fault and set to energise at the start of
the time out period (See Se tion 3. RELAY 2 SETTING).
•The hara ters “Io>” will display to indi ate the Low-set has been triggered.
•If the urrent ontinues to in rease above the High-set setting, the hara ters
“Io>” will hange and display “Io>>” to indi ate the High-set has been
triggered.
•When the unit finally trips, the digits will stop flashing and remain highlighted.
This allows the user to see what aused the unit to trip.
•The red “Tripped”
“Tripped”“Tripped”
“Tripped” LED will also flash.
•The relays whi h energised are also displayed on the s reen after tripping.
•Press to reset and return the unit ba k to normal operation (assuming
the fault has been leared). The LCD reverts ba k to displaying the normal
system urrents and the red “Tripped”
“Tripped”“Tripped”
“Tripped” LED stops flashing.
 If either relay is set for Auto resetting, then they would have de-energised after the
fault had cleared. The corresponding relay ident (i.e. R1 and/or R ) on the display
would also disappear. Pressing the “RESET”
“RESET”“RESET”
“RESET” button will only clear the LCD. If either
relay is set for Manual resetting, then pressing the “RESET”
“RESET”“RESET”
“RESET” button will de-energise the
relay(s) and clear the LCD.
In the event of an arth fault condition, the basic sequence of events is shown
below.
