The P9640 (from the P9600 series family of IDMT/DT relays) is a micro rocessor based relay
designed to monitor and detect Earth faults in 3- hase a lications. Ty ically the P9640 is
wired in conjunction with external current transformers of the feeder to be rotected.
The P9640 can be su lied with either a Normal Inverse 1.3/10 or Normal Inverse 3/10
tri ing curve. This should be s ecified at the time of ordering. Either version is clearly marked
at both the front and rear of the roduct.
The adjustments and indicators are laid out to hel the user during set-u and fault finding.
The adjustment for the Low

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 relay. The relay will energise when the “TEST”

•S TTING & OP RATION
Setting of the P9640 is carried out using the 3 otentiometers located behind the
trans arent cover.
1. Time Multiplier (TM (k))
The adjustment for “TM
“TM“TM
“TM (k)

defines the tri ing characteristic when the “Low

threshold “Io>”
“Io>”“Io>”
“Io>” has been exceeded. The lower the
setting, the faster the res onse to tri ing. The higher
the setting, the slower the res onse.
2. Low-Set Trip threshold (Io>)
The adjustment for the “Low
“Low“Low
“Low-

set” can be set from
0.1 to 2A. When the threshold is exceeded due to an
Earth fault condition, the corres onding red LED above
the adjustment illuminates indicating activity. When
tri ing finally occurs, the red LED will then flash.
3. High-Set Trip threshold (Io>>)
The adjustment for the “High
“High“High
“High-

set”set”

x1 to x10 then disable i.e.
The scale markings are multi liers of what has been
set on the “Low

“Low

set”set”

“High“High
“High-
--
-set”
set”set”
set” x6, this will be
the equivalent of 1.5 x 6 = 9A.
When the threshold is exceeded due to an Earth
fault condition, the corres onding red LED above the
adjustment illuminates indicating activity. When tri ing
finally occurs, the red LED will then flash.
 If tripping occurs whereby the High-set level is exceeded, only the LE for the
High-set will illuminate/flash. This allows the user to clearly identify which threshold
was triggered causing the trip.
 There is no delay associated with High-set therefore, tripping is instantaneous.
•L D FUNCTION SUMMARY

this out on each side.
•Insert the P9640 into the anel cut-out and fit the side cli s back on to the
housing.
•Slide the cli s towards the front of the unit until they come in to contact with
the reverse of the anel. The unit is now secured in lace.
•Connect wires to the rear terminals as required.
•The P9640 is now ready for owering and setting.
 The front window of the P9640 is supplied with a clear protective film which can be
removed as and when necessary.
•NORMAL OP RATION
•A ly ower to the unit and the green “Power supply” LED will illuminate.

•Press and hold the button and the relay will energise. Both the red
“Io>” and “Io>>” LED’s will illuminate.
•Release the button and the relay will remain energised.
•Press the button to de-energise the relay. Both red LED’s will
extinguish.
 Testing should be carried out on a regular basis to check the integrity of the
P9640.

“TEST” mode. This should only be
done by means of operating isolators, circuit breakers or other
methods of removing power in this application.
Installation work must be carried
