4.3. Parameterization - Nominal current setting

• Activate the reset button for more than 6 s to reach the operating mode "Parameterization" - the green
LED PWR flashes once.
The LEDs are switched off at intervals of 2 s for 0.3 s in the operating mode "Parameterization" to
differentiate from other operating conditions.
• Set the nominal current of the drive with the 240°
potentiometer. The nominal current is specified
in 16 stages. The four LEDs display the set
current.
• Store the value by pressing the reset button
again (retentive area of the memory).
• Actuate the Reset key for more than 2 s (and less
than 6 s) to display the set current for 3 s.
This function is possible only if
1) the device is not activated, and
2) there is no defect in the device.
From a motor current of 12 A or 45 A,
the blocking monitor is activated
(refer to 8.1. Tripping characteristics).

5. Application Examples

5.1. EMERGENCY STOP
Integrating a hybrid motor starter into an EMERGENCY STOP chain is pictured in Fig. 3 (page 54).
Here, the control voltage supply is switched off via the safety relays, as soon as the EMERGENCY STOP
button is actuated.
Switching off the control voltage supply with a controlled motor always results in wear in
the hybrid motor starter.
This switch should only be used if no more than 10,000 shutdowns can be expected over the entire
lifespan system.
If the switch-off is performed, for instance, from a "safe controller" with semiconductor outputs, the
residual voltage must be < 5 V DC. Interruptions ≤ 1 ms are filtered.

5.2. Safety door (EMERGENCY STOP and EMERGENCY OFF)

A circuit according to Fig. 4 (page 55) should be used in applications in which the safety switch-off is a
normal operating state, such as in the safety door or in two-hand applications.
Not the control supply voltage but the control circuit is switched in this application.
If the switch-off is performed, for instance, from a "safe controller" with semiconductor outputs, the
residual voltage must be < 0.5 V DC. Interruptions ≤ 1 ms are filtered.
