Cable Connection; Commissioning; Setup Of The Limit Switches; Test Run - Auma ED 25 Montageanleitung

 For installing electric lines and the mains connection the regulations for the installation of power systems and
equipment, as well as the provisions of the local Electricity Board must be observed!
 Check the mains connection voltage and frequency for conformity on the name plate of the actuator and also the
name plate of the driving motor.
 The conductor cross section must always be laid out according to the respective power consumption of the actuator
and the required length of the line. Cross section of the conductor for this type of actuator: 1 mm² – 2,5 mm².
In case of a fault: Hazardous voltage while protective earth conductor is NOT connected! Electric shock possible.
 Start running the device only after having connected the protective earth conductor.
Short-circuit due to pinching of cables! Electric shock and functional failures possible.
5.1

Cable connection

Hazardous voltage! Electric shock possible.

Disconnect device from the mains before lifting hood.
On principle the wiring diagram enclosed or glued into the hood is applicable.
Replace blanking plug by suitable cable glands.
1. Remove cable sheathing.
2. Strip wires.
3. For flexible cables end sleeves according to DIN 46228 may be used.
4. Connect cables according to order-related wiring diagram.
The enclosure protection IP... stated on the name plate is only ensured if suitable cable glands and dummy plugs are
used.
Attention has to be taken especially when actuator is used in explosive atmosphere.

Commissioning

Pay attention to moving parts during the mounting and adjustment. There exists the danger of being injured and the
risk of essential material damages.
The hood of actuators with option "dust explosion proof" can only be opened if there is no danger of
explosion.
The actuator without hood may be short-term-operated only during test run respectively for indispensible
adjusting works on electrical options such as potentiometer, travel switch or electronic positioner.
During this activity there exists access to dangerous live, blank, moving and rotating parts. In case of
inappropriate or incautious execution of the adjusting works can cause death, severe physical injuries or
essential material damages.
The operation of the actuator without hood is interdicted for a purpose different to what has been described as
mentioned before.
Figure 5.1: Setup of the limit switches
6.1

Setup of the limit switches

Move actuator into end positions. Open eccentric tappet (1) with a wrench SW 10 and adjust switch cam with a screw
driver (7). Close eccentric tappet with wrench (see figure
It is recommended to switch off the actuator with limit switches to increase life cycle.
6.2

Test run

6.2.1 Check direction of rotation

 Move actuator manually to intermediate position or to sufficient distance from end position.
 Switch on actuator in running direction CLOSE and observe the direction of rotation.
 If the direction of rotation is wrong, switch off immediately.
 Check wiring (bridges). Correct phase sequence in case of 3~phase power supply.
 Repeat test run.
Valve damage due to incorrect direction of rotation due to non-functioning of end switches when rotation is wrong.

6.2.2 Check limit switching

In case of wiring of switches is not done factory-made, the switching off in end position has to be checked:
Actuate the switching lever of the DE-switches and WE-switches with an insulated screw driver and check whether the
corresponding switches actually switch off the motor.
If necessary, interchange the inset motor feed bridges.
