•OP RATION & OV RVI W
The P9670
P9670P9670
P9670 (from the P9600 series family of IDMT/DT relays) is a micro rocessor based relay
designed to monitor and detect Overcurrent on individual hases in a 3- hase a lication. Ty ically
the P9670
P9670P9670
P9670 is wired in conjunction with external current transformers of the feeder to be rotected.
A clear backlit LCD rovides all the key information that the user requires for both o eration and the
setting u . Setting is achieved in a few sim le ste s and requires no revious knowledge of roduct
o eration.
Normal o eration rovides the user with actual live individual hase currents all on one screen. The
actual hase current re resents that of the current assing through the rimary side of the externally
connected CT’s. This is achieved by the setting of the ratio for the CT.
Programming mode allows the user to assign the o eration of both internal relays for either Auto or
Manual resetting. Relay 2 has the added o tion of being allowed to energise at the start or end of a
time out eriod. If assigned to energise at the start, the Relay can be used to o erate a buzzer or
lam giving early warning before a system actually shuts down.
Low-set and High-set thresholds can be rogrammed for the Overcurrent detection. The time
current characteristic of the low-set units are selectable between Normal Inverse curve 3/10,
Normal Inverse curve 1.3/10, Long Time Inverse curve, Very Inverse curve, Extremely Inverse
curve, Extremely Inverse 0.65 curve and Definite Time. High-set units are the Definitive Time ty e.
Instantaneous tri ing is ossible by setting the time to minimum.
A sim le Summary screen is dis layed once the rogramming is com lete. The same screen can also
be dis layed by subsequent resses of the “R S T” button. This allows the user to access key
information with the tam er roof trans arent cover closed and sealed.
A Test mode is rovided (also accessible with the tam er roof trans arent cover closed) to confirm
the correct o eration of the internal relays. The relays will energise when the “T ST” button is
ressed and de-energise when the button is released (AUTO Reset) or when the “R S T” button is
ressed (MAN reset).
Following a tri condition, the information about the tri is then stored. This can then be recalled
later if required using the “R S T” button to access the information. The P9670
P9670P9670
P9670 has the ability to
store u to 10 tri s and using the “U ” and “Down” buttons, allows each tri to be dis layed
individually. Each tri is also marked with a time stam showing the time from ower u as well as
the time from the revious tri . This feature is very useful for establishing a attern on articular
in uts, knowing when they occurred and how frequent!

1A. TOROID RATIO
 Setting the Toroid Ratio will allow the “actual” Phase currents (IL1, IL , IL3)
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”

Notes during programming
 If during programming it is necessary to abort, press the button briefly.
 Pressing and holding either or for >1sec. will increment or decrement
the new value at a quicker rate.
 Stepping through each User Setting screen is performed by pressing and holding
the button until the desired screen is displayed.
Short presses of the button will allow further editable settings to be changed
within a specific screen.
 If the user remains in a setting or summary screen where no adjustments or button
presses are made within a certain period, the screen will revert back to Normal
operation. Additionally, any settings that have been made but not stored will not be
saved.
 “O/C” refers to Overcurrent.
•TRIPPING MOD
•A fault which develo s on a hase will be indicated by an increase in current
reading on the LCD. When the level of current exceeds the Low-set setting,
the hase at fault will be highlighted by the digits flashing.
•The LCD backlight will flash.
•Relay 2 will energise if assigned to Overcurrent and set to energise at the start
of the time out eriod (See Section 3. RELAY 2 SETTING).
•The characters “I>” will dis lay to indicate the Low-set has been triggered.
•If the current continues to increase above the High-set setting, the characters
“I>” will change and dis lay “I>>” to indicate the High-set has been
triggered.
•When the unit finally tri s, the digits of the hase at fault will sto flashing and
remain highlighted. This allows the user to see which hase was at fault and
caused the unit to tri .
