ZIEHL-ABEGG ECblue Assembly Instructions

1
Factory setting: E1 min. = 5 %, E1 max. = 100 %
0.5...10 V
0...100 % speed setting
I.e. the motor starts with 6 % of the rated speed at a setting signal of approx. 1 V.

Example: E1 min. = 0 %, E1 max. = 100 %
0....10 V
0...100 % speed setting

Example: E1 min. = 0 %, E1 max. = 50 %
0....5 V
0...100 % speed setting
5.10 Voltage supply “10 V DC”
Voltage supply for activation of the digital input and external components, e.g. for a potentiometer for
speed setting (PELV current source according to EN 60204-1).
Connection: “10 V” - “GND” (max. load
Technical data und connection diagram).
During an overload or short-circuit (10 V - GND), the control voltage (and thus the device) is
disconnected . Automatic start after elimination of the cause of error.
It is not permissible to connect outputs of several devices to each other!
5.11 Connection terminal type A-G-247NW for service
If necessary an external terminal can be connected. This can be e.g. necessary to adapt the pre-
setting during start-up.
The connection is made by a 4-wire cable at the terminals: A (D+), B (D-) and GND. E. g. telephone
cable type: J-Y (St) Y 2x2x0.6 (or similar), maximum cable length approx. 250 m.
The voltage supply of the terminal is made by the accumulators inserted there or the plug power
supply unit.

5.12 Digital input “D1” for enable (device ON / OFF)
Electronic ON / OFF control via floating contact at terminals “+10V” - “D1” (input resistance and
voltage range
Technical data).
Function factory setting for “D1”:
•
Device “ON” for closed contact.
•
Device “OFF” with opened contact.
Relay “K1” remains energized, connections 11 - 14 bridged.
Status Out with flash code:
| 1 | ( Diagnostics / Faults).
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!
5.13 Relay output “K1” for fault indication
An external fault indicator is available over the potential-free contact of the built-in relay (max. contact
rating see Technical data and connection diagram).
Function factory setting for “K1”:
•
For operation the relay is energized, connections “11” and “14” are bridged. For fault the relay is de-
energized (see Diagnostics / Faults).
•
When switching off via enable (D1 = Digital In 1), the relay remains energized.
