8.1 Connecting the
device
1. Make sure that Egil and the breaker are
grounded as illustrated below:
2. Connect the power supply cable to Egil.
3. Attach the transducer to the breaker rod or to
the operating mechanism.
4. Connect the motion transducer cable to the
MOTION connector.
5. Connect Egil to the breaker.
Connect the time measurement cable to
the breaker main contacts and to Egil
TIMING contact (15).
6. Connect the auxiliary contact measurement
cable to the auxiliary contacts in the operat-
ing mechanism and to Egil AUX1&2 contact
(16).
6a. If the measurement is on wet (AC voltage)
auxiliary contacts, set the timing auxiliary
inputs to wet mode (LED is off).
6b. If the measurement is on wet (DC voltage)
auxiliary contacts, set the timing auxiliary
inputs to DRY mode (LED is on).
The red
cable must be connected to the positive
side of the auxiliary contact
6c. If the measurement is on dry auxiliary
contacts, set the timing auxiliary inputs to
DRY mode (LED is on).
7. Connect the breaker close coil to Egil close
coil output (10).
8. Connect the breaker trip coil to Egil trip coil
output (12).
9. Make sure a jumper is connected between
the trip coil input (11) and the close coil
input (8).
10. Connect the auxiliary voltage plus (+) to the
coil input (9) on Egil.
11. Turn Egil power switch on (3).
Select measurement
method
1. Select MOTION from the ANALOG CHAN-
NEL menu.
2 . Choose the measurement method.
If you use a rotating transducer or a linear transducer that is
not directly mounted on the moving contact, select measure
method STROKE LENGTH. Enter the moving contact’s
nominal stroke length and press ENTER. For more infor-
mation, see section 6.4 “Analog Channel”.
If you use a linear transducer that is directly mounted on
moving contact, select measure method TRANSD
LENGTH. Enter the transducer’s length and press ENTER.
If the exact length of the transducer is unknown, you can
find out what it is by calibrating the transducer. For more
information, see section 6.4 “Analog Channel”.
Egil is now ready for motion measurement. Remember that
the first operation must be a single close or open operation.
Connect the transducer
1. Connect the OUT terminal to one end of the
position transducer (potentiometer).
2. Connect the IN terminal to the slide of the
transducer.
3. Connect the 0 terminal to the other end of
the transducer.
4. The cable shield should not be grounded
on the transducer side.

Resistive position transducer with
very low resistance:
When the resistance is below 100 ohm, an external power
supply has to be used, e.g. two torch (flashlight) batteries
in series. Connect them across the transducer as shown
below.
Except for extra power supply there is no difference in the
way a low resistance position transducer is used.
