Power-Up

When you connect the TeSys H motor starter to the control supply, the four LEDs flash for 1 s, stay lit for 1 s, and then go off. The location of the LEDs is shown in the product description.

When you set the nominal current for the first time, the LEDs light up as indicated in the following procedure. When you change the nominal current, the behavior of the TeSys H motor starter and the sequence of LEDs depend on the state of the TeSys H motor starter.

WARNING
HAZARD OF INADEQUATE MOTOR PROTECTION The current setting of the TeSys H motor starter must be adapted in accordance with the motor to be protected. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Setting the Nominal Current for the First Time

Before you start the following procedure, make sure that the following conditions are met:

The TeSys H motor starter is powered up.
The 110–230 Vac or 24 Vdc LED is on and the other LEDs are off.
No run commands are on control inputs I1 or I2.

Step	Action
1	Lift the cover on the front of the TeSys H motor starter to access the SET/RESET button.
2	Press and hold down the SET/RESET button for at least 6 s. After 6 s the 110–230 Vac or 24 Vdc LED flashes once.
3	Release the SET/RESET button.
4	Turn the potentiometer to select an approximate nominal current, and then fine-tune the position until the LEDs indicate the exact nominal current that you want. The LEDs light up in a combination that indicates the nominal current. See the table of LED combinations and corresponding nominal current.
5	Press the SET/RESET button to save the selected nominal current. The 110–230 Vac or 24 Vdc LED comes on and the other LEDs go off.
6	Drop the cover back over the front of the TeSys H motor starter.

NOTE: The factory setting for LZ.H2X4 is 0.18 A. The factory setting for LZ.H6X5 is 1.5 A.

Changing the Nominal Current

Before you start, make sure that the following conditions are met:

The TeSys H motor starter is powered up.
The 110–230 Vac or 24 Vdc LED is on and the other LEDs are off.
No run commands are on control inputs I1 or I2.

Step	Action
1	Lift the cover on the front of the TeSys H motor starter to access the SET/RESET button.
2	Press and hold down the SET/RESET button for at least 6 s. When you are holding the button down, the LEDs flash in a combination that indicates the normal current.
3	Release the SET/RESET button. The LEDs stay lit.
4	Turn the potentiometer to select an approximate nominal current, and then fine-tune the position until the LEDs indicate the exact nominal current that you want. See the table of LED combinations and corresponding nominal current.
5	Press the SET/RESET button to save the selected nominal current. The 110–230 Vac or 24 Vdc LED comes on and the other LEDs go off.
6	Drop the cover back over the front of the TeSys H motor starter.

Checking the Nominal Current

Before you start, make sure that the following conditions are met:

The TeSys H motor starter is powered up.
The TRIP/ERR LED is off.
No run commands are on control inputs I1 or I2.

Step

Action

1

Lift the cover on the front of the TeSys H motor starter to access the SET/RESET button.

2

Press and hold down the SET/RESET button for 2–5 s.

When you are holding the button down, the LEDs flash in a combination that indicates the nominal current. See the table of LED combinations and corresponding nominal current.

NOTE: If you hold down the SET/RESET button for more than 6 seconds, you start the procedure to set the nominal current after the first time.

3

Drop the cover back over the front of the TeSys H motor starter.
