Tip
Write the calibrated transducer length on
the transducer. Then you only have to
choose TRANSD LENGTH and enter the
calibrated transducer length rather then
calibrate the transducer length each time.
Example:
1.
Choose MOTION and CALIBRATE
2. Choose TRANS POSITION 1. Move the
transducer to a position near the end
position. Voltage is shown in the display
window that corresponds to the transduc-
er’s set position. If Egil displays the error
message “Out of range”, the transducer is
too close to the end position. Correct and
mark the position on the transducer. Then
press ENTER to position 2 in Egil.
3. Choose TRANS POSITION 2. Move the
transducer slide to a position near the
other end position. Voltage is shown on the
display that corresponds to the transduc-
er’s position. If Egil displays the error
message “Out of range”, the transducer is
too close to the end position. Press ENTER
to read the position 1 in Egil. If Egil dis-
plays the error message “Too small diff”,
then the difference in voltage between
position 1 and 2 is too small. Start the
calibration again from the beginning.
4. Decide DISTANCE POS 1-2. Measure the
distance between the two marks on the
transducer as accurately as possible. Enter
the value in Egil. Press ENTER.
5. Egil displays the transducer length that
resulted from calibrating. Make sure the
value seems reasonable and press ENTER.
The value you enter will be valid until you
perform a new calibration, enter a new
transducer length, change measurement
method or turn off Egil.
6. Perform a measurement. The first measure-
ment that is taken must be a single opera-
tion.
The choice CURRENT
The current in the breaker’s close and open loops is
automatically registered on the special current channel in
Egil. If you want to measure other currents, you can use
Egil’s analog channel. One example of this could be if there
are relays in the circuit that makes it impossible to measure
the current through the close/trip coil via the control wires.
In this case, you can measure current on the analog channel
with help of a current shunt that is connected in series with
the circuit you will measure current in.
Example:
1.
Choose CURRENT from the ANALOG CHAN-
NEL menu.
2. Enter the current shunt’s resistance when
Egil prompts you to do so. Press ENTER.
This value is valid until you enter a new
value for current shunt or turn off Egil.
If you do not know the current shunt’s resistance, you can
calculate it by dividing total ampere into total millivolt.
These values are located on the shunt. For example, if the
shunt has the value 20A/200 mV, that means the resistance
is 200/20 = 10 mW.
The choice VOLTAGE
The analog channel can also be used to measure voltage.
If the voltage is between -4 and 4V, it can be directly
connected to the input. If the voltage is higher, an external
voltage divider must be used. Because the voltage divid-
er’s ratio is entered in Egil, Egil can calculate and present
the result with real values.
Example:
Choose VOLTAGE from the ANALOG CHANNEL
menu.
Enter the voltage divider’s ratio when Egil prompts you
with EXT. VOLT. DIVIDER. The value to the left of the
colon represents the input voltage that must be applied to
the divider in order to get 1V out. For example, if the
voltage divider used gives 1V, when 400V is connected,
you enter the value 400:1. If you are not using a voltage
divider, but instead connect the measuring device directly
to the channel, the setting must be 001:1.
Open speed (option)
The functions in this menu allow you to input calculation
points for open speed calculation.
Note! You must choose MOTION in the ANA-
LOG CHANNEL menu in order to activate
the open speed
The open speed is calculated as an average speed between
two points on the motion graph. In order to make this
calculation, these two points must be entered in Egil. You
