Instruction manual Installation
59
Ensure that the circuit breaker is accessible to operating personal at all times!
Additionally ensure that all breakers installed are clearly marked in terms of
function, signal type and EA device name (i.e. EA supply, EA return line etc.)
Procedure
1. Connect the unit plug for the power supply and the unit plug for position feedback
according to wiring diagram, see Chapter “Wiring diagram EA25/45/120/250”. Make
sure that the cable routing does not point upwards.
component wear, error signals and false fail safe return signals due
If the voltage is removed when reaching the end position, the status signal of the
end position is omitted and the actuator controls again the now
energized position.
This causes the LED to flash red or green, as well as premature relay
wear.
During normal operation avoid switching off the control power to the actuator.
E.g. connect the inputs OPEN/CLOSE as a changeover contact
2. If necessary, connect the ready for operation monitoring (terminal 5.6 NO), see
Chapter “Wiring diagram EA25/45/120/250”.
3. If necessary, adjust the end positions; see Chapter “Adjusting end positions”.
4. If necessary, adjust the heating element; see Chapter “Adjusting the heating element”.
Upon delivery, the heating element is set as follows:
T < 0 °C (< 32°F) heating element is heating
T > 5 °C (> 41°F) heating element switches off again
If required, the switch-on threshold can be set up to 40 °C (104°F).
