Danger due to electric current
•
Do not replug the jumper under voltage, observe the safety instructions!
•
Make sure the signal has the correct polarity!
•
Never apply line voltage to analog inputs!
5.9 Output voltage “10 V”
Voltage supply e.g. for speed setting by external potentiometer.
Connection: “10 V” - “GND” (max. load
Technical data und connection diagram).
•
It is not permissible to connect voltage outputs of several devices to each other!
•
It is not permissible to connect voltage outputs in the device to each other!
5.10 Voltage supply for external devices (+24V, GND)
A voltage supply is integrated for external devices e.g. a sensor (max. current load see technical
data).
In case of overload or short circuit (24 V – GND), the external power supply is shut down (multi-fuse).
The device performs a “Reset” and continues operation.
•
It is not permissible to connect voltage outputs of several devices to each other!
•
It is not permissible to connect voltage outputs in the device to each other!
5.11 Digital input “D1” for enable (device ON / OFF)
Electronic disconnection and Reset after motor fault via floating contact at terminals “D1”- “24V (input
resistance and voltage range
Technical data)”.
Function factory setting for “D1”:
•
Device “ON” for closed contact.
•
Device “OFF” with opened contact.
Activation via floating contacts, a low voltage of approx. 24 V DC is connected.
Danger due to electric current
•
No disconnection (no potential isolation in accordance with VBG4 §6) in remote control of the
device!
•
Never apply line voltage to the digital input!
5.12 Relay outputs “K1”
An external fault indicator is available over the potential-free contact of the built-in relays (max. contact
rating
Technical data and connection diagram).
Function factory setting for “K1”:
•
For operation the relay is energized, connections “13” and “14” are bridged. For fault the relay is de-
energized (
Diagnostics / faults).
•
When switching off via enable (D1 = Digital In 1), the relay remains energized.
5.13 Bypass circuit
Please observe the following during bypass switching (controller shunt with mains voltage):
•
Mutual locking of mains contactor and bypass protection.
•
Time delay of at least 1 second during switching.
•
When the contactor is switched off at the inverter output, the “enable” (ON / OFF) must also be
opened and closed again when it is switched back on. When switching off, wait at least 90 seconds
before switching back on!
•
Never apply line voltage to the inverter output!
