•OP RATION & OV RVI W
The P9660
P9660P9660
P9660 (from the P9600 series family of IDMT/DT relays) is a mi ropro essor based relay
designed to monitor and dete t an Earth fault urrent by measurement of the imbalan e of the
urrent from a urrent transformer arrangement as shown in the Conne tion Diagram on Page 6.
A lear ba klit LCD provides all the key information that the user requires for both operation and the
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 the a tual live earth fault urrent on one s reen. The a tual
urrent represents that of the urrent passing through the primary side of the externally onne ted
CT. This is a hieved by the setting of the ratio for the CT.
Programming mode allows the user to assign the operation of both internal relays for either 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 the 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.
A simple Summary s reen is displayed on e the programming is omplete. The same s reen an also
be displayed by subsequent 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 the 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 P9660
P9660P9660
P9660 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 knowing when
tripping o urred and how frequent!

1A. TOROID RATIO
 Setting the Toroid Ratio will allow the “actual” Earth fault current (Io) to be
displa ed on the LCD which represents that of the current flowing through the parallel
connected, external CT’s. If no CT’s are used, the parameter should be set to 5/5 (i.e.
1:1). Use this if the fault current is likel to be <5A.
 Default setting is “5/5”
•Press and hold the button. The LCD displays a s reen showing the
