Checklist

Before first starter

 All controls are turned on

 Touch-Free PRO Start unit (on start or 2 minutes before start depending on timing mode)

 Clock synced in all hardware (ETS1,ECB,ECU,eScan,eLink)

 Loops laid on finish-line. Use a test emiTag to verify that the electronic finish line is placed where you want it to be placed, else move the loops accordingly. You should test the finish-line-field on the right of the run-in, on the left of the run-in and in the middle of the run-in

After the event

 All controls are turned off

Controls

• Controls of type Touch-Free PRO (TFP) should be used during events.
• On major events there should be two control units at each control

Turn on the controls

Controls must be switched on before the event by pressing the on/off switch for some seconds.

When the TFP is switched on, the led-diod on the control blinks fast for a couple of seconds

TFP-controls are active for 36 hours after being activated and is automatically turned off after that time. It’s possible to extend the active time for a control by a short press on the on/off button. When doing this the control will blink fast for a couple of seconds and a new 36 hour period is started.

NOTE The active period of a TFP is NOT extended automatically when someone punches the control. It’s 36 hours from being switched on independently of punches

Punching range

Punching range with a TFP when standing still is 75cm, the range is reduced when punching in high speed.

Placing of controls

Start

At the start a Touch-Free Start PRO unit should be used to clear the emiTag before the start.

If nominal start time is used, the start unit should be placed so that the runner clears/zeroes their emiTag 2 minutes before the actual start time. This will also act as a check that the emiTag is working.

When the emiTag is held in the field of the Touch-Free start Pro it should blink to verify that the emiTag is working. The emiTag will stop blinking if being inside the punching field to long.

Measuring the actual start time

The actual start of the race can then be conducted in different ways

Nominal start time

Let the runner start at their preallocated start time at the sound of beeps from a clock

Start gate (if 1/10th of seconds are required)

If timing requires 1/10 seconds precision, a start gate should be used to measure the exact start time of the competitior.

The start time should be measured with the same clock as the finish time. This can be done by connecting the start gate by two-wire to the start ports of the ETS1 used for the Finish Line

«Free» start time

If the runner can start when they decide themselves or that the actual start time should be measured, it’s possible to use a ETS1 at start with loops in the ground measuring the exact start time of the runner. Passing that loop will also clear the emiTag once again, but a Touch-Free Start PRO should anyway be used before the start to test that the emiTag is working.

Finish

For small races and training a TFP Finish unit can be used for finish the race. For all major events the finish should be constructed with loops in the ground connected to a ETS1 or ECB1 so that you can pass the finish line at full speed.

The punching code when two loops are used is 248, and 90 when only one loop is used

Finish line loops

There should be two loops in the ground connected to an ETS1 or ECB.

Place the eLine loops as shown on the illustration:

Place the loops on the ground and place a heavy rubber mat on top of the loops. If ground is soft it may be possible to dig the loops down in the ground

Make sure that the loops are stable and lie safely, so that they do not disconnect and cause damage! Place the loops in the run-in and run the cable to the finish booth (with the ECB1). Remember that the blue loop ALWAYS must be placed in front of the finishing line and the white loop ALWAYS must be placed behind the finishing line.

The blue eLine loop has a black plug which is to be connected to the black patch cable, and then to ‘LOOP 1’ port on the ECB1.

The white eLine loop has a colourless plug which is to be connected to the patch cable with a white shrink tube (or with a colourless plug) and then to the ‘LOOP 2’ port on the ECB1.

Security zone around finish line

Note that the signals from the eLine loops may have a range of several meters You should establish a ‘security zone’ of about 3,5 meters to the sides of the loops and about 5 meters parallel to the race direction to avoid errors with wrongly registered competitors passing in another track.

Loop indicators on ECB and ETS1

The LED’s marked ‘LOOP 1’ and ‘LOOP 2’ are green when the eLine loop is connected and functioning. A red light indicates that the eLine loop is disconnected or not functioning. An orange light indicates that the eLine loop was disconnected when the power was switched on, or that the connection has been broken, but is now OK. A blue light indicates that no connected antenna is needed.

This may be the case when you wish to use the ECB1 with only one eLine loop. In such cases you connect the eLine loop to ‘LOOP 1’, and the ‘LOOP 2’ LED will be blue.

emiTag

At the competitions the skiers are using emiTag(s), strap the tag around the wrist and fasten it with safety pins.

For races broadcasted on TV, our recommendation is that each runner carries two emiTags (on the same wrist) for redundancy. Note that if runners are assigned two emiTags, they will not recognize only one of them blinking at a control (for example when punching very fast) and you will risk having to read and merge punches from both emiTags at the finish.

Punching is performed by holding the emiTag 0-50 cm from the control for a short moment. The LED light in the emiTag will start flashing, and keeps flashing for 5 seconds after the punch.

NOTE! It is important to see this flashing, since this is the only feedback telling you that the punch is performed correctly!

When allowing the use of personal emiTags on WRE races, there should always be a possibilty to test the emiTag before starting. emiTags with a number lower than 4103640 must be replaced in 2024. For more information New emiTag | Emit.

Readout

The readout is normally performed with an ECU or eScan connected to the timekeeping system for time, splittimes and punch verification

Note that readout equipment that are close to each other should operate with different codes. You can use codes 250,251,252 and 253 for reading out the chip.

If there are some errors with the punching. Raw data/splits from the emiTag can be printed with an eScan or MTR5

If the timekeeping system does not deliver splittimes an eScan or MTR5 can be used to give competitors splittimes immediately after the competition.
