Inverse Denite Minimum Time
(IDMT) Overcurrent Relay
The P9650 (from the P9600 series family of IDMT/DT relays) is a microprocessor
based relay designed to monitor and detect over currents in 3-phase
applications. Typically the P9650 is wired in conjunction with external current
transformers (1 per phase) of the feeder to be protected.
Adjustments & indicators are laid out in a way to help the user during set-up and
fault finding. eg. The adjustment for the LOW SET has its corresponding red
LED positioned above it so it is clear which function this LED relates to.
The same applies to the HIGH SET adjustment & LED.
Adjustment and LED operation is explained further on the next page.
The adjustment for TM (k), which defines the curve response to tripping, is
assigned to the LOW SET triggering only. The HIGH SET does not have any
additional adjustments nor does the HIGH TRIP INSTANTANEOUS if triggered.
The HIGH SET can be set to disabled, if required.
A T EST mode is provided to confirm the correct operation of the internal relays.
The relay will energize when the TEST button is pressed and de-energise when
the RESET button is pressed.
When an over current occurs in one of the phases and the level of the current
exceeds the LOW-SET I> trip threshold, the corresponding red LED above
the adjustment illuminates. The time out then commences, no matter the
point at which tripping occurred either by:
A) the level of current that is above the trip threshold.
B) the Time Multiplier Setting.
When tripping finally occurs, the red LED will then flash indicating a
tripped condition. If the fault current has been removed, pressing the RESET
button will return the relay back to normal operation & the red LED will
then extinguish.
Example 2.
If a fault current occurs such that it exceeds the HIGH-SET I>> trip
threshold, the relay will de-energise with no delay & the red LED above the
HIGH-SET I>> adjustment will flash indicating a TRIPPED condition.
If the fault current has been removed, pressing the RESET button will
return the relay back to normal operation. The red LED will then extinguish.
In the event of an over current condition, the basic sequence of events is
shown below assuming HIGH-SET trip is enabled.

INSTALLATION
Installation work must be carried
out by qualified personnel.
BEFORE INSTALLATION, ISOLATE THE SUPPLY. THIS
PRODUCT IS D ESIGNED TO CONNECT TO SEVERAL TYPES
OF CIRCUITS. ENSURE ALL ARE ISOLATED.
Lift the raised part of the side clip in order to remove from the housing.
Insert the P9650 into the panel cut-out and fit side clips back onto the housing.
Slide the clips towards the front of the unit until they come in to contact with
the reverse side of the door. The unit is now secured in place.
Connect wires to the rear terminals as required.
The P9650 is now ready for powering and setting
The front window of the P9650 is supplied with a clear protective film which
can be removed as and when necessary.
NORMAL OPERATION
Apply power to the unit and the green power supply LED will illuminate.
TEST MODE
Press and hold the button and the relay will energize. Both the red I> & I>>
LED’s will illuminate.
Release the button and the relay will remain energized.
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
P9650. DO NOT use this product to provide a means of isolating circuits in
order to work on when placed in the TEST mode. This should only be done by
means of operating isolators, circuit breakers or other methods of removing
power in this application.

LED FUNCTION SUMMARY
The green LED will remain illuminated for as long as power is applied
to the Aux. connections ( terminals 1 and 2).
In response to an over current condition:
In response to Test and Reset button operation:
Status I> I>>
Normal
Low-set triggered
Low-set Tripped
High-set triggered
High-set Tripped
Button press I> I>>
Setting of the P9650 is carried out using the 3 potentiometers located behind
the transparent cover.
1. TIME MULTIPLIER (TM (k)) defines the tripping
characteristic when the LOW-SET threshold “I>” has
been exceeded. The lower the setting, the faster the
response to tripping. The higher the setting, the slower
the response.
2. LOW-SET TRIP threshold (I>) can be set from 2 to 6A.
When the threshold is exceeded due to an over current
condition, the corresponding red LED above the
adjustment illuminates indicating activity. When tripping
finally occurs, the red LED will then flash.
3. High-Set Trip threshold (I>>) adjustment can be set
from x1 to x10 or disable =
The scale markings are multipliers of what has been set on
the LOW-SET threshold. For example if the LOW-
SET is set to 4A and HIGH-SET to 8, this will be the
equivalent of 4 x 8 or 32A. When the threshold is
exceeded due to an over current condition, the corresponding red LED
above the adjustment illuminates indicating activity. When tripping finally
occurs, the red LED will then flash. If tripping occurs whereby the HIGH-
SET level is exceeded, only the LED for the HIGH-SET will 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.
